Here's what we look for:
- Materials like stainless steel, glass, and ceramic
- 100% PFAS-free nonstick coatings, with ceramic tested for heavy metals
- Aluminum only if it’s hard anodized, ceramic-coated, or safely encased in stainless
- No plastic in contact with food (but we avoid it wherever possible)
- Transparent brands that disclose all materials

How to Swap to Non-Toxic slow cookers:
Here's how to swap to non-toxic slow cookers:
What to know about slow cookers
Slow cookers heat food at low temperatures for long periods, which means whatever the cooking insert is made of stays in contact with your food for hours. That extended contact makes the materials of the insert, lid, and any nonstick coating especially important.
- The cooking insert (or crock) is the most important part to evaluate since it holds your food for 4–10 hours at a time.
- Lids, sealing rings, and any plastic components near the cooking area also matter since heat can cause materials to release unwanted substances.
Review the slow cooker you already have
Check what your slow cooker's insert is made of and whether any nonstick coatings or plastic parts come into contact with food. Look at the product box, manual, or manufacturer's website for material details.
- Ceramic and stoneware inserts are common and generally a good sign — but check whether the manufacturer confirms they are tested free of lead and cadmium.
- If your insert has a nonstick coating, look for whether the brand confirms it is PFAS-free (not just PTFE-free) — these are different things.
Use your current slow cooker more safely
If you're not ready to replace your slow cooker, a few small changes can reduce direct contact between food and materials you're unsure about.
- Use oven-safe glass or stainless steel inserts inside the crock as a liner, or look for food-grade parchment slow cooker liners instead of plastic ones.
- Avoid using scratched or chipped nonstick inserts — damaged coatings can release more particles into food over long cooking sessions.
Choose a cleaner slow cooker
Look for slow cookers with inserts made from stainless steel, ceramic, or stoneware that has been tested free of lead and cadmium. Avoid models with nonstick-coated inserts unless the brand confirms the coating is completely PFAS-free.
- Prioritize models where no plastic touches your food — BPA-free plastic on handles or the exterior is fine, but it shouldn't line the lid or contact the cooking area.
