Ingredients (With Sizes)
Here’s what you’ll need for a classic brunch casserole:
• 8 large eggs
• 2 cups (480 ml) whole milk
• 1 teaspoon salt
• ½ teaspoon black pepper
• ½ teaspoon garlic powder
• 1 loaf (about 10 cups) day-old bread, cubed
• 1½ cups (170 g) shredded cheddar cheese
• 1 cup (120 g) shredded mozzarella or Monterey Jack
• 1 lb (450 g) breakfast sausage or bacon, cooked and crumbled
• 1 small onion, finely diced
• 1 cup (150 g) chopped bell peppers
• 2 tablespoons butter (for greasing the dish)
Preparing the Base
Start by greasing a large baking dish with butter. Spread the cubed bread evenly across the bottom. This creates the foundation of your casserole and helps soak up all the delicious egg mixture.
Next, sprinkle the cooked sausage or bacon over the bread, followed by the onions, peppers, and half of the cheese. These layers ensure every bite is full of flavor.
Mixing the Eggs
In a large bowl, whisk together the eggs, milk, salt, pepper, and garlic powder until smooth. This mixture is what ties the whole casserole together.
Slowly pour the egg mixture over the bread and fillings. Press gently with a spoon so the bread absorbs the liquid evenly.
Topping and Baking
Sprinkle the remaining cheese over the top. Cover the dish with foil and refrigerate for at least 30 minutes or overnight if you want to bake it fresh in the morning.
When ready to bake, preheat your oven to 350°F (180°C). Bake covered for 30 minutes, then uncover and bake for another 15–20 minutes until the top is golden and the center is set.
Serving Suggestions
Let the casserole rest for 10 minutes before slicing. This helps it hold its shape. Serve it with fresh fruit, a green salad, or roasted potatoes for a complete brunch spread.
It’s also delicious with a drizzle of hot sauce or a spoon of sour cream on top.
Make It Your Own
You can customize this casserole endlessly. Swap sausage for ham, use spinach instead of peppers, or add mushrooms, tomatoes, or herbs. The base stays the same—the flavors are up to you.
