Instant Pot Stainless Steel Inner Pot vs. Glass Casserole Dish

Materials

• 18/8 stainless steel interior
• No non-stick coating

Common claims

• Food-grade stainless steel
• Multi-function cooker
• No PTFE coating

Concerns / watch-outs

• Some models offer non-stick inner pots as accessories — avoid those and stick with the stainless insert
• Gasket/seals are silicone; replace per manufacturer schedule

Notes

The standard stainless insert is one of the cleanest cooking vessel options. Avoid the optional non-stick insert accessories if PFAS avoidance is a priority.

Cleaner alternatives

• stainless steel
• enameled cast iron

Materials

• Tempered or borosilicate glass

Common claims

• Oven-to-table serving
• Non-reactive surface
• Easy cleanup

Concerns / watch-outs

• Tempered glass can shatter with thermal shock — avoid moving from freezer directly to hot oven
• Borosilicate glass is more thermal-shock resistant than standard tempered glass

Notes

One of the most inert baking surfaces available. Choose borosilicate glass for better thermal shock resistance. Avoid the broiler, which can create extreme temperature differentials.

Cleaner alternatives

• glass bakeware
• enameled cast iron
