Can You Put Pyrex in an Air Fryer?

Short answer

Yes - but bring it to room temperature

Yes, you can put Pyrex in an air fryer. It is oven-safe bakeware and an air fryer is just a small convection oven. The catch is thermal shock: an air fryer heats far faster than an oven, so never put fridge-cold Pyrex into a preheated basket.

Why Pyrex behaves this way

Pyrex is oven-safe by design, so the basic answer is straightforward - if it is happy at 400°F on your oven shelf, it is happy at 400°F in an air fryer basket. There is no microwave radiation involved, so none of the metal-and-arcing folklore applies. What does apply, and applies harder than in a conventional oven, is thermal shock.

There is a wrinkle worth knowing. Older Pyrex, and Pyrex sold in Europe today, is borosilicate glass, which shrugs off sudden temperature changes. Much of the Pyrex sold in the United States since the 1990s is tempered soda-lime glass instead - cheaper, tougher against knocks, and noticeably less tolerant of thermal shock. Since an air fryer goes from cold to 400°F in about two minutes and blows that heat straight at the dish, it is a more abrupt environment than an oven shelf. So the rule is simple regardless of which type you own: let the dish sit out until it is room temperature, and cool it on a dry board rather than a wet worktop.

The rules

  • Let Pyrex reach room temperature before it goes into a preheated fryer.
  • Never take it straight from the fridge or freezer into a hot basket.
  • Cool it on a dry trivet or wooden board - never a cold or wet worktop.
  • Leave a gap around the dish so hot air can still circulate.

What goes wrong

  • Thermal shock can crack or shatter it - air fryers heat much faster than ovens, so the change is more abrupt.
  • Modern US Pyrex is soda-lime glass, which tolerates sudden temperature swings less well than borosilicate.
  • A dish that fills the basket blocks airflow and cooks unevenly.
  • Chipped or crazed glass is far more likely to fail under heat.

Pyrex in an air fryer: FAQ

Can you put Pyrex in an air fryer?

Yes. Pyrex is oven-safe and an air fryer is a small convection oven. The one precaution is thermal shock - bring the dish to room temperature first, because an air fryer heats much faster than a conventional oven.

Will Pyrex shatter in an air fryer?

Only from thermal shock, not from the heat itself. Cold glass meeting a fast-heating fryer is the risk. Room-temperature Pyrex going into a preheated basket, and cooling on a dry surface afterwards, is fine.

Is all Pyrex the same?

No. Older and European Pyrex is borosilicate glass, which handles temperature swings well. Much US Pyrex made since the 1990s is tempered soda-lime glass, which is less tolerant of thermal shock. Treat whichever you own with the same care and you will not have a problem.

Can you put Pyrex in an air fryer straight from the fridge?

No - this is exactly the situation to avoid. A cold dish dropped into a preheated air fryer is asked to expand very fast and very unevenly, and that is what cracks glass. Let it stand until it is at room temperature.
