Larger tomatoes should be sliced in half. Even for small cherry tomatoes I usually cut them in half because it makes them cook fast.
2. Drizzle
Put the tomato halves in a bowl and drizzle them with the olive oil. Sprinkle on the salt and garlic powder and toss the tomatoes so they are coated in spices.
3. Air Fry
As the tomatoes air fry they will release a fair bit of juice. This means that the air fryer can be kind of messy after cooking them.
If want you can put a piece of parchment paper in the bottom of the basket. You can buy perforated parchment paper specifically cut to fit, which results in minimal cleanup.
Put the tomato halves in the air fryer basket, spreading them out so they don’t overlap. Don’t overfill the basket.
My 5.8 quart Cosori air fryer has no problem fitting 1 pint of cherry tomatoes. But if all the tomatoes won’t fit then cook them in batches.
Air fry the tomatoes at 390 degrees F for 8-10 minutes. When they are done the tomatoes should have released a lot of liquid and be a little charred, but not blackened.
Larger tomato halves will need a longer cooking time than cherry tomatoes. Cook them at 390 degrees F for 20-25 minutes.
