Step-by-Step Instructions

Preparation Steps

1. First, preheat your oven to 350°F (175°C). This helps cook the casserole evenly.

2. Next, grease a 9×13 inch baking dish. You can use non-stick spray or butter for this.

3. In a large skillet, cook 1 pound of breakfast sausage over medium heat. Break it apart with a spatula. Cook until the sausage is fully browned. Drain any extra grease and set it aside.

Mixing Ingredients

1. In a big mixing bowl, beat together 6 large eggs and 1 cup of milk.

2. Stir in 1 teaspoon of garlic powder, 1 teaspoon of onion powder, and salt and pepper to taste.

3. Add the cooked sausage, 1 cup of diced bell peppers, 1 cup of diced onion, and 1 cup of shredded cheddar cheese to the egg mix. Stir well to combine.

4. Gently fold in 4 cups of cubed day-old bread. Make sure all the bread pieces are coated in the egg mixture.

Baking the Casserole

1. Pour the mixture into the greased baking dish. Spread it out evenly.

2. Top the casserole with the remaining 1 cup of shredded cheddar cheese.

3. Bake in the preheated oven for 30-35 minutes. Check if it’s done when it is puffed, set in the center, and the cheese is golden and bubbly.

4. After baking, let the casserole cool for 5-10 minutes. This makes it easier to slice. Garnish with fresh parsley before serving.
