Slow cookers: stainless vs ceramic vs coated inserts

Ignore stainless exteriors. We score the insert: bare stainless or traditional uncoated ceramic can pass or partial; ceramic-nonstick coatings fail.

On this page
How to read verdicts: passes metal/glass primary path (silicone seals OK if disclosed). partial usable if you skip a coated accessory, or plastic remains on lids. fails plastic or fluoropolymer/nonstick in the normal use path.

360 Cookware 6 Quart Slow Cooker Set

360 Cookware 6 Quart Slow Cooker Set

PASSES

360 Cookware · Model 6 Quart Slow Cooker Set (stock pot + base)

Why: Removable multi-ply stock pot with T-316 surgical-grade stainless food-contact surface and matching stainless steel cover (brand Q&A: all lids stainless). Zero chemical nonstick coatings. Vapor seal is metal-to-metal moisture film — no PTFE and no plastic crock. Exterior phenolic knobs on classic lines are handle/knob hardware, not the cooking surface.

Cuisinart slow cookers (typical ceramic or coated inserts)

PARTIAL

Cuisinart · Model Category

Why: Most Cuisinart slow cookers use ceramic stoneware (uncoated glaze) — partial like KitchenAid. Some easy-clean lines use coatings — check SKU. Default score partial for ceramic; flip to fail if the listing says nonstick coating.

PARTIAL

HOUSNAT · Model 6QT 10-in-1 (ASIN B09J95V2DG) · 4.1★ (474 ratings)

Why: 304 stainless inner pot and tempered glass lid are strong, but the lid gasket/seal polymer is not named on the Amazon listing. Under site methodology an unnamed gasket demotes this from a pass to partial until the seal is disclosed.

Instant Pot Duo (stainless pot) used on Slow Cook

PARTIAL

Instant Pot · Model Duo / Duo Plus stainless

Why: Same 18/8 stainless pot as pressure mode — excellent uncoated metal insert. Lid sealing ring is silicone and lid has plastics, so partial as a full appliance; strong pass for the cooking surface alone.
