Prepare the Ingredients
Cook the Breakfast Meat
Begin by cooking your choice of breakfast meat in a pan. Whether you go for bacon, sausage, or ham, make sure the bacon gets crispy for added texture. Once cooked, crumble or chop the meat into small pieces and set it aside.
Prepare the Bread
Cut your bread into cubes. If you're using fresh bread, lightly toast the cubes to help them hold their shape during baking. This step is crucial to ensure the casserole doesn’t turn out soggy.
Chop the Vegetables
If you’re adding vegetables to your casserole, now is the time to chop them. Sauté the vegetables, such as bell peppers, onions, or spinach, in olive oil until they are soft and fragrant.
Grate the Cheese
Grating your cheese fresh will help it melt more smoothly. Pre-shredded cheese is convenient, but fresh cheese always yields the best results.
Assembling the Casserole
Preheat the Oven
Start by preheating your oven to 350°F (175°C) and grease a 9x13-inch baking dish to prevent sticking.
Mix the Egg Base
In a large mixing bowl, whisk together the eggs, milk, salt, pepper, and any spices you're using, such as mustard powder or paprika. Mix gently to avoid overbeating.
Add the Bread and Other Ingredients
Add the cubed bread to the egg mixture, making sure every piece is thoroughly coated. Stir in the cooked meat, sautéed vegetables, and shredded cheese. Mix until everything is evenly distributed.
Transfer to the Baking Dish
Pour the casserole mixture into the prepared baking dish. Spread it out evenly, ensuring there are no gaps and the mixture is well-distributed.
Baking the Casserole
Cover the casserole with aluminum foil and bake it in the preheated oven for about 40-45 minutes. After that, remove the foil and bake for an additional 10-15 minutes, or until the top is golden brown and the casserole has set. Let it cool for a few minutes before serving.
