NOPE
If I put the air fryer inside the oven, does it cook faster?
No, sticking your air fryer inside the oven won't speed things up; it's like putting a microwave inside a fridge and hoping for faster cold.
Putting an air fryer inside an oven doesn't make food cook faster. Air fryers work by circulating hot air directly and quickly around the food inside their compact chambers. Tossing one into a larger oven just turns it into dead space and ruins airflow, potentially making cooking slower or uneven. Use each appliance as intended—your air fryer inside an oven is just unnecessary clutter, not a speed boost.
