Begin by thinly slicing the 2 large onions (either yellow or red). Aim for consistent thickness for even cooking.

In a large bowl, add the thinly sliced onions, 1 tablespoon of olive oil, 2 tablespoons of cornstarch or flour, 1/2 teaspoon of garlic powder, 1/2 teaspoon of smoked paprika, 1/2 teaspoon of salt, and 1/4 teaspoon of black pepper. If using, add 1 tablespoon of grated Parmesan cheese.

Toss all the ingredients together thoroughly until the onion slices are evenly coated with the oil and seasoning mixture. Ensure each piece is well-covered.

Preheat your air fryer to 350°F.

Place the seasoned onion slices in the air fryer basket in a single layer, ensuring not to overcrowd the basket. Overcrowding will result in steamed, not crispy, onions. You may need to cook in multiple batches depending on the size of your air fryer.

Air fry for 10-15 minutes, shaking the basket halfway through (around the 5-7 minute mark) to ensure even cooking and crispiness. Continue cooking until the onions are golden brown and crispy.

Once golden brown and crispy, remove the onions from the air fryer. Serve immediately as a topping for burgers, salads, soups, casseroles, sandwiches, or enjoy them as a snack on their own.
