I tested the healthiest, non toxic slow cookers and I'm sharing the best ones. The best non-toxic slow cooker is made with glass, stainless steel, or unglazed clay and without PTFE, PFAS, non-stick coatings, leaded ceramic glazes, silicone, nano-ceramic, or aluminum food contact surfaces.

For those who want to cut to the chase, the best non toxic Crockpot dupe is Instant Pot hands down. For a truly non-toxic slow cooker, Magnifique Glass Pot Multi-Cooker is the safest.

Toxins in Slow Cookers

  • PTFE, PFOA, and PFAS: Traditional non-stick coatings like Teflon are built on PFAS chemistry — the "forever chemicals" that don't break down. PTFE coatings can degrade and release fumes when overheated or scratched.
  • Lead and cadmium in glazes and enamel: These heavy metals have historically shown up in ceramic glazes, especially in bright colors like red, orange, and yellow.
  • Reactive or unlined aluminum: Bare aluminum can leach into food, especially acidic dishes like tomato-based stews.
  • Vague or undisclosed metal alloys: "Stainless steel" isn't one material — cheaper grades can contain more nickel or chromium and are more prone to leaching. Brands that specify the actual grade (like 18/8 or 316 surgical-grade steel) are giving you more to go on.

Materials Used in Non-Toxic Slow Cookers

  • Glass: completely inert, no coatings or glazes, but can shatter under thermal shock.
  • Stainless steel: no coating to wear off, though trace nickel/chromium can leach with acidic foods.
  • Unglazed clay: no glaze layer to hide lead or cadmium in, but the pot itself is a consumable, fragile part.
  • Cast iron (enameled, lead-free glaze): durable and inert once properly enameled, but heavy and glaze quality varies by brand.

What to Look For

For a truly non toxic slow cooker look for pure, unglazed clay or stoneware, glass, 18/8 or surgical-grade stainless steel with no coating, or enameled cast iron. Out of all the materials, glass is the least toxic. If you do want non-stick convenience, look for a ceramic coating that's specifically certified PFAS-free.

I tried VitaClay Nourishing Pot Slow Cooker

VitaClay's new Nourishing Pot is a 12-in-1 unglazed, fired clay pot that's lead-free, aluminum-free, and Teflon-free. This is basically earth oven cooking for the modern day. The double-lid design creates a light micro-pressure that speeds cooking and locks in moisture. It's got a dedicated bone broth mode, and it's programmable for up to 24 hours.

  • Material: Unglazed organic clay pot and clay lid, no metal food-contact surface
  • Capacity: 6.5 qt
  • Power: 120VAC / 60Hz / 700W
  • Price: $350

I tried GreenPan Elite Slow Cooker

GreenPan's Elite is a mid-range non-toxic slow cooker with a PFAS-free ceramic nonstick pot. Its sear function sets it apart — it browns at up to 400°F right in the pot. Chili and stews come out tender without turning mushy. On the plus side, even dried-on food wipes right off.

  • Material: Hard-anodized aluminum inner pot with Thermolon Volt ceramic nonstick coating (made without PFAS, PFOA, lead and cadmium)
  • Capacity: 6 qt
  • Price: $299.99 (often on sale for $200–$250)

I tried Our Place Dream Cooker

Our Place Dream Cooker is the most modern slow cooker I've tried — a 6-quart touchscreen multicooker that handles pressure cooking, slow cooking, searing, and keep-warm. The inner pot is aluminum with a toxin-free ceramic non-stick coating, compliant with California's AB 1200 nonstick cookware regulations.

  • Capacity: 6 qt
  • Weight: 12.9 lb
  • Functions: Pressure Cook, Slow Cook, Sauté/Sear, Keep Warm
  • Compliance: Meets California AB 1200 nonstick cookware disclosure requirements
  • Price: $199

I tried Magnifique Glass Pot Multi-Cooker

Magnifique's Glass Pot Multi-Cooker is the ONLY slow cooker made with 100% non-toxic borosilicate glass that's third-party tested to be free of heavy metals and PFAS. There's no coating that could chip, crack, peel or wear off over time. Glass is completely inert so it won't ever leach chemicals into food, even with acidic or hot ingredients.

  • Price: $129.99
  • Material: Borosilicate glass pot and lid, stainless steel steam tray, no coatings or plastic components
  • Capacity: 4.5 qt
  • Power: 1,130W (120V / 60Hz)
  • Testing: Third-party tested, free of heavy metals and PFAS

I tried GreenLife Slow Cooker by GreenPan (budget!)

GreenLife is the budget sister brand of GreenPan and the most affordable option. It uses GreenPan's Thermolon Volt ceramic non-stick coating, made without intentionally added PFAS. It's the lightest slow cooker I've ever tried. For a simple, no frills entry level machine that's healthier than your typical slow cooker, this could be a decent option.

  • Capacity: 6 qt
  • Power: 240W
  • Price: $54.99–$119.99 depending on size

I tried Instant Pot Duo 7-in-1

Instant Pot is the best non toxic Crockpot dupe in my experience. It's made from food-grade 304 (18/8) stainless steel with no non-stick coating — no PTFE, no PFOA. Independent lab testing on the stainless inner pot has consistently come back non-detect for lead, cadmium, and mercury. It does it ALL: pressure cook, sous vide, steam, saute, slow cook, rice, porridge, and yogurt.

  • Price: $100-$150 depending on size
  • Material: 304 (18/8) stainless steel inner pot and lid, no non-stick coating
  • Capacity: 6 qt
  • Power: 1,000W (120V / 60Hz)
  • Safety: UL and ULC certified, 10+ built-in safety mechanisms

360 Cookware Stainless Steel Slow Cooker

360 Cookware is another truly non toxic slow cooker made from T-304 surgical-grade stainless steel. By nature stainless steel is still chromium and nickel bonded into the metal, so there's still a chance those elements can migrate at a trace level. This is why glass is the safest least toxic material.

  • Material: T-316 surgical-grade stainless steel, tri-ply construction, no coating
  • Capacity: 4 qt (2.3 qt and 6 qt also available)
  • Warranty: Lifetime
  • Price: $439.95 for 4 qt | $479.95 for 6 qt

I tried Caraway Dutch Oven (Manual)

If you're looking for a manual nontoxic slow cooker, Caraway Dutch Oven is the safest because it's independently tested to be free of PTFE, PFOA, PFAS, lead, cadmium, and other heavy metals. It's an enameled cast iron Dutch oven you slow cook in manually. Cast iron's heat retention makes it excellent for slow braises.

  • Material: Enameled cast iron with a 3-layer enamel coating, free of PTFE, PFOA, and PFAS
  • Capacity: 6.5 qt
  • Oven-safe: Up to 500°F
  • Warranty: Lifetime
  • Price: $265
