Instructions
Spray your 7-inch baking pan with cooking spray or line with parchment paper, then preheat air fryer to 320°F (160°C).
Heat olive oil in a skillet over medium heat. Sauté onion and bell pepper for 3-4 minutes until softened. Add tomatoes for 2 minutes, then stir in spinach for 1 minute until wilted. Set aside.
Whisk eggs, milk, salt, pepper, and garlic powder in a bowl for 30-45 seconds until smooth and frothy.
Stir 3/4 cup of cheddar into the egg mixture, then gently fold in the sautéed vegetables. Reserve 1/4 cup cheddar for topping.
Pour mixture into prepared pan, spread vegetables evenly, tap pan to release bubbles, and sprinkle remaining cheddar on top.
Place pan in air fryer and cook at 320°F (160°C) for 16-18 minutes. Do not open during first 12 minutes. Center should be set with slight jiggle when done.
Carefully remove pan and let rest for 5 minutes. Top with feta and fresh herbs, then slice and serve warm.
Notes
Take eggs out of the refrigerator 30 minutes before starting for even cooking.
Always sauté vegetables first to release excess moisture and intensify flavor.
Use whole milk or heavy cream for a creamier texture; avoid skim milk.
Don't overfill the pan; the frittata needs room to puff up.
Every air fryer is different, so check at the 14-minute mark the first time.
Let the frittata rest for the full 5 minutes before cutting to prevent it from falling apart.
For meal prep, sauté vegetables the night before and store in the refrigerator.
For clean slices, spray your knife with cooking spray before cutting.
Store leftover slices in the refrigerator for up to 4 days or freeze for up to 2 months.
Reheat in the air fryer at 300°F for 3-4 minutes for the best texture.
