Is there a slow cooker with a stainless steel insert UK? Yes—but you need to look carefully at the cooking pot, not the exterior. Some UK multicookers, including the Instant Pot Duo 7-in-1 and Instant Pot Pro 5.7L, have genuine stainless-steel inner pots and a Slow Cook setting. By contrast, many traditional products advertised as “stainless steel slow cookers” have a stainless-steel outer housing and a completely different ceramic or coated cooking bowl.
If your priority is to cook food directly against an uncoated stainless-steel surface, choosing by the words printed on a retailer’s listing is not enough. This UK guide explains verified options, how to identify the inner bowl, where to look for compatible replacements, the difference between stainless steel and non-stick coatings, and the practical drawbacks of using a multicooker for slow cooking.
Is There a Slow Cooker With a Stainless Steel Bowl Available?
Yes. Genuine stainless-steel bowls exist in UK appliances offering a slow-cooking programme. The clearest examples are multi-use electric cookers with functions such as pressure cooking, sautéing, steaming and slow cooking. Some traditional single-purpose slow cookers use metal inserts too, but a metallic appearance does not establish that the food-contact surface is uncoated stainless steel.
For example, the Instant Pot Duo 7-in-1 5.7L UK product page specifically lists a dishwasher-safe stainless-steel cooking pot, while the Instant Pot Pro 5.7L information describes a stainless-steel inner pot with handles. Both are electrical multicookers rather than simple ceramic crock-style appliances.
The distinction matters for expectations. A traditional slow cooker generally concentrates on Low, High and perhaps Keep Warm. A multicooker has more cooking modes, additional controls and sometimes a different heating profile. Having Slow Cook printed on the control panel does not mean every recipe will behave identically to a traditional ceramic slow cooker.
How to Tell Whether a Slow Cooker Really Has a Stainless Steel Insert
Check the manufacturer’s description of the removable inner cooking pot. A specification that says “stainless steel housing”, “stainless steel finish”, “brushed stainless steel exterior” or merely “stainless steel appliance” may describe the outer casing only.
| Product wording | What it establishes | What to check next |
|---|---|---|
| Stainless steel exterior | Outer housing material | What the removable pot is made from |
| Removable ceramic bowl | Food contacts ceramic or stoneware | Not a stainless-steel insert |
| Non-stick metal pot | Food contacts a coating | Whether it is stainless steel underneath, and whether the coating matters to you |
| Uncoated stainless-steel inner pot | Food contacts stainless steel | Grade, compatibility, cleaning instructions and replacement availability |
| 18/8 or 304 stainless-steel insert | Manufacturer identifies a stainless-steel grade | Whether the exact appliance also supports Slow Cook |
Photos can be misleading. A shiny silver interior might be stainless steel, but polished aluminium and some coatings can look similar. Find an exact material statement in the manual or official product specification before buying.
What Is the Best Slow Cooker With a Stainless Steel Insert UK?
For readers who specifically want an uncoated stainless-steel inner pot and an integrated Slow Cook setting, these manufacturer-documented multicookers provide useful starting points. “Best” depends on whether you value simpler controls, pot handles, cooking capacity or additional pressure-cooking features—not merely the material.
| UK option | Stainless-steel inner pot | Slow Cook function | Most relevant distinction |
|---|---|---|---|
| Instant Pot Duo 7-in-1, 5.7L (Duo 60) | Yes, removable uncoated steel pot | Yes | Multi-use cooker with a straightforward classic inner-pot format |
| Instant Pot Pro, 5.7L (Pro 60 / PRCPC601WE) | Yes, steel pot with handles | Yes | Different handled pot design; model-specific replacement required |
| Instant Pot Duo 3L | Yes, compatible steel pot listed for the compact Duo | Check exact model | Smaller footprint and a distinct 3L replacement part |
Instant Pot Duo 7-in-1 5.7L
The UK manufacturer describes the Duo 60 as a multi-use electric pressure cooker that includes Slow Cook and Sauté modes. Its cooking pot is stainless steel and is described as free from BPA, PFOA and PTFE. The manufacturer’s Duo cooking instructions include specific Slow Cook settings, so you can check whether its operation suits the recipes you typically make.
This model is a useful starting point if you want stainless steel but do not need to pursue the more complex features of the Pro family. It is still a multicooker, with programme choices and additional functions beyond those found on a basic slow cooker.
Instant Pot Pro 5.7L
The Pro 5.7L also includes Slow Cook and Sauté. Its manufacturer documents a handled stainless-steel inner cooking pot, which may be more convenient when removing it from the housing. The UK Pro instructions explain its Slow Cook settings and demonstrate that the model is intended to perform this function.
A handled pot can be useful, but the handles and the pot must still be treated as potentially hot. This model needs its own approved Pro-type insert; a standard Duo pot of the same advertised capacity is not interchangeable.
Instant Pot Duo 3L for Smaller Kitchens
If you cook for one or two people, a smaller multicooker may be easier to store and fill sensibly. Instant Pot UK lists a 3L stainless-steel replacement pot for the compact Duo family. Before purchasing the appliance, confirm its exact Slow Cook programmes and that the model is available in a UK specification.
None of these examples is a claim that one model wins every comparison. Check current prices, model numbers and manufacturer documentation. An in-stock appliance and an easily obtainable replacement pot are practical buying advantages, but stock changes.
Are Traditional Stainless Steel Slow Cookers the Same as Stainless Steel Multicookers?
No. The terms describe different things. A conventional slow cooker uses a dedicated electrical base and removable bowl and normally provides a small number of cooking settings. A multicooker combines several functions in one appliance, including Slow Cook and often pressure cooking.
A multicooker can be attractive when you want an uncoated steel food-contact surface, but it may cost more, occupy more space or have more complicated controls than a conventional slow cooker. Slow Cook settings and timings can differ, so the manufacturer’s guidance matters.
If you’re weighing up materials rather than functions, see our ceramic-versus-aluminium slow cooker comparison and guide to ceramic slow cooker pots. Those articles cover different materials; this guide specifically addresses stainless-steel inner vessels.
Where Can I Find a Stainless Steel Slow Cooker Insert in the UK?
Start with the appliance manufacturer’s official UK spare-parts catalogue. Search for the exact model number printed on the cooker base, plus “inner pot”, “stainless steel” and its capacity. Don’t start with a generic marketplace insert simply because it looks the right size.
Instant Pot UK has separate replacement pots for several product families. For example, its standard 5.7L Duo-family stainless-steel inner pot is listed for selected Duo, Duo Nova, Duo Plus and Duo Crisp models. The listing explicitly excludes Pro and other incompatible variants.
The separate 5.7L handled Pro-family inner pot fits specified Duo Evo Plus, Pro and Pro Plus models, but not the standard Duo. There is also a separate Instant Pot Plus 5.7L replacement pot for model RPPC61-BK only.
Important: These manufacturer listings were marked out of stock at the time of research, so they confirm that genuine compatible parts exist but do not guarantee immediate availability. Check availability directly with the manufacturer or an authorised supplier, without substituting an unapproved vessel.
Can You Replace a Ceramic Slow Cooker Bowl With Stainless Steel?
Usually not unless the manufacturer explicitly approves a compatible stainless-steel replacement for that particular appliance. A ceramic slow cooker housing is designed for a certain insert shape, size and way of transferring heat. A different metal bowl may not fit or heat as intended.
A third-party insert with a similar diameter or litre capacity is not proof of safe compatibility. The same applies to pressure multicookers: correct fit, sealing performance and heating behaviour can be safety-critical. Do not use random replacement pots, other brands’ inserts or generic saucepans in an electric slow cooker.
If you own a ceramic slow cooker and want to avoid a ceramic food-contact surface, the most reliable path may be buying an appliance specifically supplied with an approved stainless-steel inner pot rather than trying to retrofit your current cooker.
Are Stainless Steel Slow Cookers Non Toxic?
Good-quality stainless steel intended for food contact is widely used in kitchen equipment. It is typically durable, corrosion-resistant and does not need a conventional non-stick coating to function. But “non-toxic” is not an automatic guarantee about every product or condition of use, and it is better to examine the steel grade, construction and official food-contact information than to rely on broad advertising.
The UK’s Food Standards Agency guidance on food-contact materials describes the legal framework for materials intended to contact food. The UK Health Security Agency’s nickel information notes that nickel is used in stainless-steel alloys. For people with specific medically diagnosed metal sensitivities or dietary restrictions, the material grade may warrant individual advice.
A scientific UK Committee on Toxicity review of nickel explains that nickel release from good-quality stainless steel food-contact materials is generally of limited relevance compared with overall dietary exposure, while poorly made materials may behave differently.
Instant Pot UK describes its selected 5.7L spare pots as 18/8 (Grade 304) stainless steel with an impact-bonded base incorporating an aluminium core for heat distribution. That does not mean food touches exposed aluminium; the manufacturer’s specification identifies the food-contact vessel as stainless steel. If you specifically want to avoid a conventional synthetic non-stick coating, check whether the exact inner pot is described as uncoated.
Is Stainless Steel Better Than Ceramic or Non-Stick?
| Feature | Uncoated stainless steel | Ceramic or stoneware | Coated metal |
|---|---|---|---|
| Food-contact surface | Steel alloy | Glazed ceramic | Non-stick or other coating |
| Cleaning | May need soaking for stuck food | Often easy for stews; care varies | Often easy while coating remains intact |
| Weight | Varies by construction | Often heavy | Often relatively light |
| Scratch concerns | No coating to scratch off, but surface can mark | Can chip or crack | Requires care to avoid coating damage |
| Hob and oven use | Model-specific | Model-specific | Model-specific |
No material automatically makes a slow cooker more nutritious or more energy-efficient. Food quality depends largely on the recipe, cooking temperatures, filling and operating time. If ceramic or non-stick is already working well for you, stainless steel is a preference rather than a universal upgrade.
Are Slow Cooker Stainless Steel Inner Bowls Easy to Clean?
Generally yes, but they clean differently from non-stick bowls. Stainless steel does not have a synthetic easy-release surface, so starch-rich foods, thick sauces or poorly stirred sautéed ingredients can leave residue on the base. This does not necessarily mean the pot is damaged.
The manufacturer lists the Duo and Pro replacement steel pots as dishwasher-safe, with polished interiors and graduated markings. Always follow the instructions for the exact product rather than assuming every metal insert and lid belongs in a dishwasher.
How to Clean an Uncoated Stainless Steel Inner Pot
- Switch off and allow it to cool. Never clean while the powered appliance is operating.
- Remove leftovers. Transfer food to suitable containers rather than leaving it standing unnecessarily.
- Wash with warm water and washing-up liquid. A soft sponge is often sufficient for fresh residue.
- Soak stubborn food. Let hot water and a little washing-up liquid loosen stuck-on food before cleaning again.
- Rinse and dry thoroughly. This can reduce water spots and make the interior easier to inspect.
- Check dishwasher permission. If the manufacturer’s pot instructions allow machine washing, follow those instructions, while keeping the electrical base completely out of water.
A stainless-steel pot may develop rainbow-like heat marks or mineral deposits. Those cosmetic changes do not automatically mean the cookware has become unsafe. Avoid harsh scrubbing tools or chemicals if the manual prohibits them. See our guide to dishwasher-safe slow cooker components for the wider distinction between pots, lids and electric housings.
Can You Sear Meat in a Stainless Steel Slow Cooker Pot?
Some stainless-steel multicookers have a Sauté programme that lets you brown meat in the same inner bowl used later for slow cooking. This can save a separate frying pan, though stainless steel may stick until the pan and ingredients are appropriately heated and managed.
The Instant Pot Pro instructions, for example, include Sauté and advise leaving the lid off during that programme and deglazing the pot afterwards. That is not permission to put an ordinary removable insert directly on a gas burner, induction hob or external cooking ring.
If searing is a priority, our UK guide to slow cookers with a sear function and guide to slow cookers with sauté functionality explain which cooking methods you are actually paying for.
Can You Use a Stainless Steel Slow Cooker Pot on an Induction Hob?
Not merely because it is stainless steel. Some steel grades and multilayer bases work on induction, but induction compatibility needs manufacturer approval and a suitable magnetic base. A multicooker insert may be specifically designed for use only inside its own powered housing.
Never put the electrical appliance base on any hob. Before placing a removable inner pot on a separate induction ring, obtain clear model-specific approval for that use. Our UK slow cooker pot and induction-hob guide provides a fuller explanation.
Are Stainless Steel Slow Cooker Pots Oven-Safe?
Again, check the specific model and the manufacturer’s instructions. Stainless steel by itself does not establish an oven rating, because handles, base construction and other components can impose restrictions. The electrical housing must never enter an oven.
Do not assume an approved stainless-steel pot means its supplied lid is also oven-safe. See our UK slow cooker pot oven-safety guide for model-by-model examples.
Do Stainless Steel Multicookers Slow Cook as Well as Traditional Slow Cookers?
They can produce very good results, but the heat delivery and lid design may differ from a traditional ceramic slow cooker. Some pressure multicookers reach slow-cooking temperatures more gradually or offer several programmable levels instead of the familiar Low and High dial.
The Instant Pot Pro’s official Slow Cook guidance describes different heating approaches for Low and High. The Duo instructions also identify Slow Cook settings and recommend using the relevant manual instructions. When transferring a recipe designed for a traditional slow cooker, start with the manufacturer’s guidance rather than assuming the same labels, timings and liquid requirements give an identical result.
If you primarily want to leave an inexpensive stew cooking on Low, a simple purpose-built slow cooker may remain the more convenient choice. If you want stainless steel and also value pressure cooking or sautéing, a multicooker can justify its greater complexity.
What Should You Check Before Buying a Stainless Steel Insert Slow Cooker?
- Food-contact surface: confirm that the inner vessel, not just the housing, is genuine stainless steel.
- Coating: check whether the food touches uncoated metal or a non-stick layer.
- Cooking function: confirm the product has a Slow Cook programme, not merely a pressure-cooking option.
- Capacity: choose a size suitable for your household and batch-cooking needs.
- Replacement compatibility: record the full appliance code, not only its litre capacity.
- Cleaning: check dishwasher instructions for the pot and lid separately.
- Controls: choose a programme interface you can operate confidently.
- Availability and warranty: verify current UK model stock, parts support and warranty conditions.

Frequently Asked Questions
Is There a Slow Cooker With a Stainless Steel Bowl Available?
Yes. Several UK multicookers, including specified Instant Pot Duo and Pro models, provide both an uncoated stainless-steel inner cooking pot and a Slow Cook programme. Many conventional slow cookers advertised with stainless steel in the title refer only to the outside housing.
What Is the Best Slow Cooker With a Stainless Steel Insert UK?
The Instant Pot Duo 7-in-1 5.7L and Instant Pot Pro 5.7L are two manufacturer-verified options worth comparing. The best choice depends on the controls, pot design, space and other functions you will actually use; neither is automatically best for everyone.
Where Can I Find a Stainless Steel Slow Cooker Insert in the UK?
Check your manufacturer’s official UK spare-parts listings using the exact model number. Instant Pot sells or lists dedicated stainless-steel replacements for certain Duo, Pro and Plus families, but some were out of stock when checked. Do not substitute a generic pot simply because it shares the same capacity.
Are Stainless Steel Slow Cookers Non Toxic?
Food-grade stainless steel intended for food contact is a widely used cookware material and can be a suitable choice for people who prefer to avoid a conventional non-stick coating. However, ‘non-toxic’ should not be treated as an absolute safety certification; check the material specification, manufacturer instructions and any relevant personal sensitivity.
Are Slow Cooker Stainless Steel Inner Bowls Easy to Clean?
Usually, yes, especially when the manufacturer permits dishwasher washing. However, food may stick more readily than on a non-stick coating, so soaking and gentle washing can sometimes be needed.
Can I Buy a Stainless Steel Replacement for My Ceramic Slow Cooker?
Not unless the original manufacturer explicitly lists an approved replacement for that exact model. Swapping materials and insert designs without approval can affect fit, heating and safe operation.
Are 18/8 Stainless Steel and 304 Stainless Steel the Same?
18/8 is a common description of an alloy containing approximately 18% chromium and 8% nickel, while 304 is a standard stainless-steel grade. Manufacturer specifications may use both terms for the same food-contact insert. Always rely on the actual listed specification rather than a general appearance.
Can Stainless Steel Slow Cooker Bowls Go in a Dishwasher?
Some can. For example, Instant Pot UK’s specified Duo and Pro stainless-steel inner pots are described as dishwasher-safe. The powered base must never be immersed in water.
The Bottom Line
Yes, you can find a slow cooker with a stainless steel insert in the UK—but the clearest verified examples are multicookers with Slow Cook programmes, particularly select Instant Pot Duo and Pro models. These use genuine stainless-steel food-contact bowls, unlike the many traditional slow cookers that have a stainless-steel outer shell but a ceramic or coated insert.
Look beyond the marketing title. Check the exact inner-pot material, whether it is uncoated, the model’s slow-cooking instructions and replacement-part compatibility. Those details are more useful than a general claim that an appliance is stainless steel.
