Preparation Process Of Make Ahead Breakfast Casserole Recipe

Start by cooking sausage, onions, and peppers until golden and fragrant. Cube bread and place it in a greased baking dish. Layer with the cooked mixture and shredded cheese. In a bowl, whisk eggs, milk, and seasonings, then pour over the bread mixture. Cover and refrigerate overnight. In the morning, uncover, bake until golden, and garnish with parsley. This process ensures flavors blend beautifully and saves morning prep time.

Step By Step Instructions

Prep the dish
Grease a 9×13 baking dish and spread cubed bread evenly inside. This forms a sturdy base that will absorb the egg mixture and hold the casserole together.

Cook sausage & veggies
In a skillet, brown sausage over medium heat. Add onions and bell peppers, cooking until tender and aromatic. Break sausage into small crumbles for even distribution.

Layer bread cubes
Arrange the cooked sausage and vegetables evenly over the bread cubes. Distribute carefully so each slice of casserole has a balanced mix of flavors and textures.

Add cheese and herbs
Sprinkle shredded cheddar and a portion of parsley over the layered mixture. This adds creaminess and freshness while enhancing the savory depth of the casserole.

Whisk eggs & milk
In a large bowl, whisk together eggs, milk, salt, pepper, and garlic powder until smooth. This mixture binds the ingredients and creates a fluffy texture once baked.

Pour custard & press
Pour the egg mixture evenly over the bread and toppings. Lightly press with a spatula so the bread absorbs liquid. Cover tightly with foil and refrigerate overnight.

Bake until set
Preheat oven to 350°F. Remove foil and bake until the top is golden, the center is firm, and a knife inserted in the middle comes out clean and dry.

Rest, garnish & serve
Allow casserole to rest for five minutes after baking. Garnish with remaining cheese and parsley, slice into squares, and serve warm for a complete meal.

• Serve with fresh fruit salad
