Ingredient Notes & Details

Eggs
The star of this baked egg recipe. Use large, fresh eggs for the best fluffy texture. Farm-fresh eggs often have richer flavor and color.

Milk or cream
Adds creaminess and helps create a soft, tender texture. For a richer casserole, use heavy cream. For a lighter version, whole milk works perfectly.

Cheddar cheese
Sharp cheddar adds bold flavor and melts beautifully. You can substitute mozzarella, Swiss, Monterey Jack, or a cheese blend for variety.

Cooked bacon or sausage
Adds savory depth and makes the casserole more filling. Turkey sausage or plant-based alternatives work well too.

Bell peppers
Provide color, sweetness, and texture. Red, yellow, or green peppers all work beautifully in this cheesy baked egg dish.

Onion
Adds aromatic flavor and balances the richness of the eggs and cheese.

Spinach
A great way to add nutrients and freshness. Fresh or frozen spinach can be used — just be sure to squeeze excess moisture from frozen spinach.

Salt and pepper
Essential for enhancing flavor. Adjust seasoning based on the saltiness of your cheese or meat.

Garlic powder
Adds subtle depth without overpowering the dish.

Olive oil or butter
Used to grease the baking dish and prevent sticking.

Step-by-Step Instructions

Step 1: Preheat the oven
Preheat your oven to 180°C (350°F). Lightly grease a baking dish with butter or olive oil to prevent sticking.

Give the oven enough time to fully preheat so the casserole cooks evenly.

Step 2: Prepare the mix-ins
Cook the bacon or sausage in a skillet until fully done. Drain excess grease and set aside.

Dice bell peppers and onion into small pieces so they cook evenly in the casserole.

If using spinach, chop it finely.

Step 3: Whisk the eggs
In a large bowl, crack the eggs and whisk until fully combined.

Add milk or cream, salt, pepper, and garlic powder.

Whisk until the mixture becomes slightly frothy — this helps create a fluffy baked egg casserole texture.

Step 4: Assemble the casserole
Spread the cooked meat evenly across the bottom of the prepared baking dish.

Add chopped vegetables and distribute evenly.

Sprinkle shredded cheese on top.

Pour the egg mixture slowly over the ingredients so everything is evenly coated.

Step 5: Bake until perfectly set
Place the casserole in the oven and bake for 35–40 minutes.

The center should be set but slightly soft. The top should be lightly golden.

If the top browns too quickly, loosely cover with foil.

Step 6: Rest before slicing
Allow the casserole to rest for 5–10 minutes after baking.

This helps the eggs firm up and makes slicing easier.

Cut into squares and serve warm.

FAQ for Common Questions
