Step-by-Step Guide
1. Prepare the baking dish
Grease a 9×13-inch baking dish with butter. Make sure all sides are coated well. This prevents sticking and helps easy serving later. Set the dish aside while you prepare the ingredients.
2. Add bread cubes
Place the bread cubes evenly in the greased baking dish. Spread them out so they cover the base completely. This creates a soft and fluffy layer once the casserole is baked.
3. Add meat and vegetables
Sprinkle chopped sausage or bacon over the bread. Add onions and bell peppers evenly. This step adds flavor and texture. Make sure everything is spread well for balanced bites.
4. Mix the egg mixture
In a large bowl, whisk eggs, milk, and cream together. Add salt, pepper, and mustard powder. Mix until smooth and fully combined. This mixture will soak into the bread overnight.
5. Add cheese
Stir in cheddar and Parmesan cheese into the egg mixture. Mix gently so it spreads evenly. The cheese melts beautifully and gives a rich and creamy texture.
6. Combine everything
Pour the egg mixture over the bread and toppings. Press down lightly so the bread absorbs the liquid. Make sure all pieces are soaked for best results.
7. Chill overnight
Cover the dish with plastic wrap or foil. Place it in the fridge overnight. This step helps the flavors blend and gives the casserole its soft texture.
8. Bake the casserole
Preheat oven to 350°F. Remove the dish from the fridge and let it sit for a few minutes. Bake for 40 to 45 minutes until golden and set in the center.
9. Rest and serve
Let the casserole cool for about 10 minutes before slicing. This helps it set properly. Serve warm and enjoy a comforting, hearty breakfast.
