How to Make Air Fryer Egg Casserole
Below, you’ll find easy step-by-step instructions with helpful tips to walk you through the process of making this air fryer breakfast casserole.
Step 1: Mix the ingredients
In a large mixing bowl, combine the cooked sausage, diced tomatoes and green chilies, and Italian seasoning. Stir everything together well, then add the shredded cheddar cheese.
Step 2: Add the eggs and cream
Crack the eggs into the mixture and pour in the heavy cream. Whisk everything together until the eggs are slightly frothy — this helps create a light, fluffy texture.

Step 3: Assemble the casserole
Divide the egg mixture evenly between the ramekins, then top each with a little extra shredded cheddar cheese
Step 4: Air fry
Set your air fryer to 340°F and cook for 5-8 minutes. Keep an eye on it, as air fryers can vary — you want the eggs to be fully set and the cheese melted and bubbly.

Step 5: Serve and enjoy!
Once done, carefully remove the casseroles from the air fryer, let them cool for a few minutes, then dig in!
Individual Breakfast Casserole Variations
- Vegetarian: Skip the sausage and add diced bell peppers, onions, and spinach for a colorful and flavorful veggie-packed casserole.
- Keto-Friendly: Use almond milk instead of heavy cream. Skip the tomatoes and add low-carb veggies like mushrooms and bell peppers.
- Tex-Mex Style: Layer refried beans and salsa between the sausage mixture and eggs, then top with a Mexican cheese blend for a spicy alternative.
- Add Potatoes: Add a layer of cooked hash browns or tater tots before pouring in the sausage and egg mixture. It’s a delicious and filling brunch option!
Air Fryer Breakfast Casserole Pro Tips
- Pre-Cook Ingredients: Cook sausage or vegetables before adding them to the casserole to make sure they’re fully cooked and flavorful.
- Prevent Sticking: Use a silicone baking pan or line your air fryer basket with parchment paper for easy cleanup and to prevent sticking.
- Let It Rest: Allow the casserole to sit for a few minutes after cooking to let the flavors come together before serving.
- Customize Toppings: Switch up the cheese or add fun toppings like avocado, salsa, or sour cream to make it your own!
Air Fryer Egg Bake FAQs
Can I use frozen ingredients in my air fryer breakfast casserole?
Yes, you can use frozen veggies or pre-cooked meats, but make sure they’re fully thawed before assembling to ensure even cooking.
Can I make this breakfast casserole ahead of time?
Absolutely! Assemble the casserole the night before and refrigerate it. When ready to eat, just pop it in the air fryer until warmed through.
How do I prevent the top of my casserole from overcooking in the air fryer?
If the top is browning too quickly, loosely cover it with aluminum foil halfway through cooking to prevent overcooking while the middle sets.
Can I make this mini breakfast casserole without eggs?
Yes! You can use a liquid egg substitute or a tofu scramble for an egg-free version.
Can I use different meats or cheeses in my breakfast casserole?
Definitely! Swap in your favorites like bacon, ham, or turkey sausage, and try cheeses like Swiss, Monterey Jack, or feta.
Why is my air fryer breakfast casserole soggy?
This can happen if there’s too much liquid in the mixture or if the ingredients release excess moisture while cooking. To avoid this, drain any watery ingredients, pre-cook vegetables and meats, and avoid adding too much cream.
Can I make a larger casserole for a group instead of individual servings?
Absolutely! If you’re cooking for a crowd, you can easily make a larger casserole by adjusting the ingredients to fit a bigger dish. Just be sure to adjust the cooking time as needed. Since an individual breakfast casserole cooks faster, it may take a bit longer for a large casserole to cook all the way through. Keep an eye on it to ensure it’s fully done!
How do I store leftovers?
Store any leftovers in an airtight container in the fridge for up to 3 days. Reheat in the air fryer for a few minutes until warm.
