Air Fryer Breakfast Casserole is quick and easy frittata with veggies, cheese and optional sausage or hashbrowns. Meal prep for breakfast or serve during holidays, this healthy breakfast will be a hit!
Preheat air fryer at 400°F for 5 minutes. Line basket of air fryer with parchment paper making sure to position it evenly in the center, so there is enough room to hold egg mixture on all sides. Trim off sticking out corners.
Remove basket from the air fryer, add spinach and stir until a bit wilted. Sprinkle with Parmesan cheese and pour egg mixture on top. Bake at 300°F for 20-30 minutes or until toothpick inserted in the middle comes out clean.
