Instructions

1. Cube 6 slices of day-old bread into 1-inch pieces and set aside. Chop 1 cup of bell peppers and 1 cup of onions into small, uniform pieces.
2. Cook 1 lb of breakfast sausage in a skillet over medium heat until fully browned and crumbly, about 8-10 minutes. Drain excess fat.
3. Drizzle 1 tablespoon of olive oil in a 9×13-inch baking dish. Spread bread cubes evenly across the bottom of the dish.
4. Layer the cooked sausage crumbles, sauteed bell peppers, and onions over the bread cubes. Sprinkle 2 cups of shredded cheese on top.
5. Crack 8 large eggs into a mixing bowl. Add 2 cups of milk, 1 teaspoon of salt, and ½ teaspoon of pepper. Whisk until smooth and fully combined.
6. Pour the egg mixture carefully over the layered ingredients, ensuring even coverage. Use a spatula to gently press down and help bread absorb liquid.
7. Preheat your oven to 350F. Cover the casserole with aluminum foil and bake for 25 minutes.
8. Remove foil and continue baking for additional 15-20 minutes until the top turns golden brown and the center sets completely.
