Origin and Cultural Significance
Egg casseroles and baked omelets are popular in many cuisines because they transform simple ingredients into a versatile, filling meal. This air fryer version combines the familiar flavors of a vegetable omelet with the convenience of a small baked casserole.
Although this particular combination is a modern home-cooking variation rather than a traditional regional dish, it fits naturally into everyday cooking, where eggs, vegetables, and cheese create a quick meal that can be adapted to different tastes.
Ingredients
For the Egg and Vegetable Mixture
- 4 large eggs
- ½ cup small broccoli florets, chopped
- ½ cup diced tomatoes
- ¼ cup diced red bell pepper
- 1 tablespoon milk or cream (optional)
- ¼ teaspoon salt, or to taste
- ⅛ teaspoon freshly ground black pepper
- Cooking spray or a little olive oil, for greasing
For the Cheese Topping
- ¼ cup shredded mozzarella, cheddar, or grated Parmesan
For Garnishing
- 1 tablespoon fresh parsley, finely chopped
Optional Additions
- Spinach: Add a small handful of chopped spinach for extra color and variety.
- Mushrooms: Include finely sliced mushrooms for a savory, earthy flavor. Cook off excess moisture before adding.
- Onions: Add a little finely diced red or yellow onion for extra flavor.
- Feta cheese: Replace some of the mozzarella with crumbled feta for a tangy finish.
- Chili flakes: Sprinkle in a pinch for gentle heat.
- Italian seasoning: Add ¼ teaspoon for a fragrant herb flavor.
- Cooked chicken or turkey: Mix in a small amount of chopped, fully cooked meat for a heartier meal.
Tips for Success
- Chop vegetables evenly: Small, uniform pieces cook more consistently and make the casserole easier to slice.
- Manage vegetable moisture: Tomatoes release liquid as they cook. Remove excess seeds or watery pulp if necessary, and avoid adding too many vegetables.
- Use a suitable baking dish: Choose an oven-safe dish or silicone mold specifically suitable for air fryer temperatures that fits comfortably inside the basket.
- Grease the dish well: A light coating of oil helps prevent sticking and makes serving easier.
- Whisk thoroughly: Beat the eggs until the whites and yolks are fully combined for a consistent texture.
- Do not overfill: Leave a little space at the top because the egg mixture may puff up as it cooks.
- Check the center: Air fryers vary in power, and deeper dishes require more cooking time. The center should be fully set, with no runny egg remaining.
- Add extra cheese carefully: A thick cheese layer can brown before the eggs finish cooking. If needed, add some of the cheese during the final few minutes.
- Rest before slicing: Let the casserole stand for 2–3 minutes after cooking so it can settle and release more easily from the dish.
Instructions
Step 1: Prepare the Vegetables
Wash the broccoli, tomatoes, and red bell pepper. Chop them into small, evenly sized pieces.
If using fresh broccoli florets, make sure they are small enough to soften during the short cooking time. For particularly firm broccoli or a thicker casserole, briefly steam or microwave the broccoli before mixing it with the eggs.
Step 2: Whisk the Eggs
Crack the eggs into a medium mixing bowl. Add the salt, black pepper, and milk or cream, if using.
Whisk until the mixture is smooth and well combined. The optional milk or cream adds moisture and can help produce a tender texture, although it is not essential.
Step 3: Combine the Ingredients
Add the chopped broccoli, tomatoes, and red bell pepper to the beaten eggs. Stir gently until the vegetables are evenly distributed throughout the mixture.
Step 4: Prepare the Baking Dish
Lightly coat a small air fryer-safe baking dish or silicone mold with cooking spray or olive oil.
Pour the egg and vegetable mixture into the dish, spreading the ingredients evenly. Sprinkle the shredded mozzarella, cheddar, or Parmesan over the top.
Step 5: Air Fry the Casserole
Preheat the air fryer to 350°F (175°C) if recommended by the appliance manufacturer.
Place the baking dish carefully inside the air fryer basket. Cook for approximately 8–12 minutes, checking around the 7-minute mark.
The cooking time will depend on the depth of the dish, the quantity of vegetables, and the air fryer model. If the top browns too quickly while the center remains undercooked, reduce the temperature slightly and continue cooking.
The casserole is ready when the eggs are fully set in the center and the cheese is melted. For food safety, the egg mixture should reach an internal temperature of 160°F (71°C).
Step 6: Garnish and Serve
Carefully remove the hot dish from the air fryer using oven mitts. Allow the casserole to rest for 2–3 minutes.
Sprinkle the chopped fresh parsley over the top, then slice or spoon the casserole onto plates. Serve warm on its own or alongside whole-grain toast, fresh fruit, or a simple green salad.

Recommendation
Serve this casserole with whole-grain toast, sliced avocado, or a fresh fruit salad for a more complete breakfast. For lunch, pair it with a leafy green salad dressed with olive oil and lemon juice.
If preparing it ahead, allow the casserole to cool, then refrigerate it in an airtight container for up to 3–4 days. Reheat individual portions in the air fryer at 300–320°F (150–160°C) until warmed through, or use a microwave for convenience.
For the best texture, add fresh parsley after reheating rather than before storing. Avoid freezing if possible, as cooked eggs and watery vegetables can become softer after thawing.
