Ingredients for a Fluffy Breakfast Bake

• 8 large eggs

• 1/2 cup shredded mozzarella cheese
• Salt and pepper to taste
• Optional: chopped fresh chives or parsley

Step-by-Step Oven-Baked Omelette Instructions

1. Preheat your oven to 350°F (175°C). Grease an 8-inch square baking dish with butter or nonstick spray.
2. In a large bowl, whisk the eggs vigorously until pale and frothy. Season with salt and pepper.
3. Gently fold in diced ham, Cheddar, and mozzarella until evenly distributed.
4. Pour the egg mixture into the prepared baking dish, tapping gently to release any air bubbles.
5. Bake for 35–40 minutes, or until the center is set and the top is lightly golden.
6. Let rest 5 minutes before slicing into squares. Garnish with fresh chives or parsley.

Tips for the Perfect Cheesy Omelette Casserole

• Use room-temperature eggs for a loftier, fluffier texture.
• For extra creaminess, stir in 2 tablespoons of milk or half-and-half.
• Mix in diced bell peppers or spinach for a veggie boost.
• Allow the bake to cool slightly—this makes slicing cleaner and neater.

Serving Suggestions and Variations

Pair your sliceable omelette with:

• Warm crusty toast or garlic bread.
• A light mixed green salad with vinaigrette.
• Salsa, sour cream, or hot sauce for dipping.
