Yes, you can put glass in an air fryer as long as it is oven-safe, rated for the temperature you are cooking at, and small enough not to block the airflow. Use tempered or borosilicate ovenproof glass, and avoid regular drinking glasses or any dish that isn’t marked oven-safe, because ordinary glass can crack or shatter from the fast, intense heat.
Important safety note
The real risk with glass is thermal shock — a sudden temperature change that can crack it. Never put cold glass straight from the fridge into a hot air fryer, and never run cold water over a hot dish. Let glass come closer to room temperature first, and let it cool gradually after.
When glass is fine to use
- Oven-safe glass dishes (such as Pyrex-type borosilicate) rated to your cooking temperature, for baking eggs, small casseroles or reheating.
- Dishes that leave space around the edges so hot air can still circulate.
- Air fryers with built-in glass bowls or containers, which are designed for the heat, see our best glass air fryers.
When to skip the glass
- Don’t use non-oven-safe glass or drinking glasses; they can shatter.
- Don’t fill the basket with a dish so large it blocks the airflow, or food won’t cook evenly.
- Don’t exceed the glass’s rated temperature. Check the base of the dish for its heat rating.
- Avoid sudden temperature changes at every step.
How to use glass the right way
- Confirm the dish is marked oven-safe and rated for your temperature.
- Choose a size that leaves room for air to flow around it.
- Let cold ingredients and the dish warm up a little before cooking to avoid thermal shock.
- Handle it with mitts, and let it cool gradually afterward.
