Recipe Variations

  • For a vegetarian twist, skip the Italian sausage and opt for diced bell peppers, onions, and spinach, adding a colorful and flavorful mix to your casserole.
  • To make it keto-friendly, replace the heavy cream with almond milk and omit the tomatoes. Instead, opt for low-carb vegetables like mushrooms and bell peppers.
  • For a Tex-Mex version, add refried beans and salsa between the sausage mixture and eggs and top with a Mexican cheese blend for a spicy kick.
  • To make it more indulgent, layer cooked hash browns or tater tots at the bottom of the baking dish before adding the sausage mixture and eggs, creating a hearty and satisfying dish perfect for brunch.

Pro Tips

Here are some pro tips to elevate your air fryer breakfast casserole:

  • Pre-cook ingredients like sausage or vegetables before adding them to the casserole to ensure they are fully cooked and retain flavor.
  • Use a silicone baking pan or line your air fryer basket with parchment paper to prevent sticking and make cleanup easier.
  • Allow the casserole to rest a few minutes after cooking to let the flavors meld together before serving.
  • To customize your casserole to your taste preferences, you can experiment with different cheese blends or toppings, such as avocado, salsa, or sour cream.
  • Consider adding a layer of shredded hash browns or diced potatoes for added texture and flavor.


Can I use frozen ingredients in my air fryer breakfast casserole? Yes, you can, such as vegetables or pre-cooked meats. However, ensure they are fully thawed before assembling the casserole to ensure even cooking.

How long does it take to cook a breakfast casserole in the air fryer? Cooking times may vary depending on the size and thickness of your casserole, but typically, they are 20-25 minutes at 350°F (175°C).

Can I make a breakfast casserole ahead of time and reheat it in the air fryer? Yes, you can assemble the casserole the night before and refrigerate it. When ready to serve, preheat your air fryer and cook the casserole until heated through.

Can I use different meats or cheeses in my breakfast casserole? Absolutely! Feel free to customize your casserole with favorite meats like bacon, ham, turkey sausage, and cheeses such as Swiss, Monterey Jack, or feta for added flavor.

How do I prevent the top of my casserole from overcooking in the air fryer? If you notice the top of your casserole browning too quickly, you can cover it loosely with aluminum foil halfway through the cooking process to prevent it from burning while the center finishes cooking.
