Ingredients
  

1 pound breakfast sausage (mild or spicy, based on preference)

6 large eggs

2 cups milk

1 teaspoon Dijon mustard

1 teaspoon garlic powder

1/2 teaspoon onion powder

1/2 teaspoon paprika

1/4 teaspoon salt

1/4 teaspoon black pepper

5 cups cubed day-old French bread

1 cup shredded cheddar cheese

1 cup diced bell peppers (red, yellow, or green)

1/2 cup green onions, sliced (for garnish)

Instructions
 

Cook the Sausage: In a large skillet over medium heat, cook the breakfast sausage until browned and cooked through. Break it apart with a spatula into small crumbles. Drain any excess grease and set aside to cool slightly.

    Prepare the Egg Mixture: In a large mixing bowl, whisk together the eggs, milk, Dijon mustard, garlic powder, onion powder, paprika, salt, and black pepper until fully combined.

      Assemble the Casserole: In a greased 9x13-inch baking dish, spread the cubed French bread evenly across the bottom. Layer the cooked sausage, diced bell peppers, and shredded cheddar cheese over the bread.

        Pour Egg Mixture: Pour the egg mixture evenly over the bread and sausage layers, ensuring all pieces are moistened. Gently press the bread down with a spatula to soak up the egg mixture.

          Refrigerate Overnight: Cover the baking dish tightly with plastic wrap and refrigerate overnight (or for at least 6 hours) to allow the flavors to meld and the bread to absorb the egg mixture.

            Preheat and Bake: In the morning, preheat your oven to 350°F (175°C). Remove the casserole from the refrigerator and let it sit at room temperature for about 15 minutes.

              Bake the Casserole: Remove the plastic wrap and bake the casserole for 45-50 minutes, or until the center is set and the top is golden brown. If the top starts browning too quickly, cover it loosely with aluminum foil.

                Garnish and Serve: Once baked, allow the casserole to cool for 5-10 minutes before slicing. Garnish with sliced green onions before serving hot.
