In a bowl, beat the eggs with Italian seasonings until well combined.
Add the broccoli florets, diced cherry tomatoes, shredded cheddar cheese and finely chopped green onion to the egg mixture. Stir until evenly distributed.
Place the bowl in the preheated air fryer basket.
Cook frittata in the air fryer for 15 minutes or until the eggs are set and the top is golden brown.
Once done, carefully remove the frittata from the air fryer and let it cool slightly before serving.
