A complete printable recipe and the measurements in both US customary and metric are available in the recipe card below.
Preparing Your Air Fryer and Ingredients
Start by preheating your air fryer to 350°F (180ºC). Double-check that your dish fits in the air fryer basket, and then lightly spray your baking dish with cooking spray. This will prevent sticking and make cleanup easier.
Mixing the Egg Mixture
In a large bowl, whisk together eggs, sour cream, milk, 1½ cups of shredded cheddar cheese, and a pinch of salt and pepper. This creates the creamy, cheesy base of your casserole.
Cooking the Veggies
Next, heat a skillet over medium heat and add some olive oil. Toss in green onions, diced bell pepper, and red onion.
Sauté for about 5-7 minutes until they’re slightly softened. Add broccoli florets at the end and cook for a couple more minutes.
Assembling the Casserole
Arrange the sautéed vegetables evenly in the prepared baking dish. Gently pour egg mixture over the vegetables in the dish, and make sure it’s spread evenly.
Next, sprinkle the remaining cheese over the top. This will give a lovely golden and cheesy crust to your casserole.
Cooking and Serving
Place the dish in the air fryer and air fry for about 20-25 minutes. You’re looking for a nice browned top and a set center. Once done, let the breakfast casserole rest for a few minutes. This makes it easier to slice. Serve warm and enjoy a deliciously hearty breakfast!
Recipe Notes and Expert Tips
- Choosing the Right Dish: Not all baking dishes are air fryer-friendly. Ensure the dish you use is oven-safe and fits comfortably in your air fryer basket. A round or square cake pan often works well.
- Don’t Overcrowd the Air Fryer: Ensure there’s enough space around the dish for air circulation. This helps the casserole cook evenly.
- Add Your Favorite Ingredients: This recipe is super flexible. Feel free to add pre-cooked veggie sausage, meat-free bacon, spinach, mushrooms, tomatoes, leftover refrigerated hashbrowns, or even leftover roasted vegetables. A dash of hot sauce can also give it a nice kick.
- Cheese: While cheddar is great, don’t hesitate to try other cheeses like mozzarella or pepper jack for a different flavor profile. Feel free to add some extra cheese if desired!
- Check for Doneness: Air fryers can vary, so start checking your breakfast casserole around the 20-minute mark. It’s done when the top is golden brown, and the center is set.
- Make-Ahead: You can assemble the casserole the night before, store it in the fridge, and pop it in the air fryer in the morning. It’s a perfect time-saver for busy mornings.
- Cook Time: Different air fryers can have a longer or shorter cook time so keep an eye on the casserole to prevent burning.

How to Store Leftover Air Fryer Breakfast Casserole
- Airtight Container: Once the casserole is completely cooled, store it in an airtight container. This keeps it fresh and prevents it from absorbing odors from the fridge.
- Refrigerate or Freeze: You can keep the casserole in the refrigerator for up to 3 days. For longer storage, freeze it in individual portions for up to 2 months.
- Reheating: Reheat refrigerated or thawed breakfast casserole slices in the air fryer or oven until heated through. This helps maintain the texture better than microwaving.
What to Serve with Air Fryer Egg Casserole
Pair with a Side of Freshness
A great way to balance the richness of the breakfast casserole is by serving it with a fresh side. Try a light Caprese Salad or a fruit salad. These add a refreshing touch and a pop of color to your breakfast table.
Veggie Breakfast Sides
If you’re serving this ninja foodi breakfast casserole for brunch or a heavier meal, pair it with other breakfast staples. Hash browns, toast, roasted tomatoes, or even some crispy mushrooms can complement the flavors in the casserole beautifully.
Make It a Brunch Spread
If you’re hosting a brunch, consider adding a few more items to create a spread. Muffins, croissants, Cinnamon Rolls, and French Toast can elevate your meal and offer something for everyone. Brunch is all about variety and indulgence!
