Ingredients Used

For the Casserole

  • 1 pound breakfast sausage – Adds rich, savory flavor
  • 6 large eggs – The base for a fluffy, protein-packed casserole
  • 2 cups milk – Ensures a creamy texture
  • 1 teaspoon mustard powder – Enhances flavor
  • ½ teaspoon salt – Balances flavors
  • ½ teaspoon black pepper – Adds a mild kick
  • 4 cups bread cubes (French or sourdough works best) – Soaks up the egg mixture for a hearty texture
  • 1 cup shredded cheddar cheese – Melts beautifully for a rich, cheesy layer
  • ½ cup diced bell peppers (optional) – Adds color and a slight sweetness
  • ¼ cup chopped green onions (optional) – Provides a mild onion flavor

For Toppings (Optional but Recommended)

  • Fresh parsley or chives – For garnish
  • Hot sauce or salsa – For added spice
  • Extra cheese – Because more cheese is always better!

Method of Preparation

Step 1: Cook the Sausage

  1. In a skillet over medium heat, cook the sausage until browned, breaking it into crumbles.
  2. Drain excess grease and set aside.

Step 2: Assemble the Casserole

  1. Grease a 9×13-inch baking dish.
  2. Spread the bread cubes evenly in the dish.
  3. Sprinkle the cooked sausage, shredded cheese, and optional vegetables over the bread.

Step 3: Prepare the Egg Mixture

  1. In a bowl, whisk together eggs, milk, mustard powder, salt, and pepper.
  2. Pour this mixture evenly over the casserole, ensuring everything is coated.

Step 4: Refrigerate Overnight

  1. Cover the dish with foil or plastic wrap and refrigerate for at least 6 hours or overnight.
  2. This allows the bread to absorb the egg mixture, enhancing flavor and texture.

Step 5: Bake the Casserole

  1. Preheat oven to 350°F (175°C).
  2. Remove the casserole from the refrigerator 30 minutes before baking to bring it to room temperature.
  3. Bake uncovered for 45-50 minutes, or until the center is set and the top is golden brown.
  4. Let it rest for 5 minutes before serving.

Cooking Tips for the Best Casserole

  • Use sturdy bread – Softer breads may become too soggy.
  • Let it sit before baking – This helps flavors meld together.
  • Check doneness with a knife – Insert it in the center; if it comes out clean, it’s done.

Common Mistakes to Avoid

  • Not draining sausage properly – Too much grease can make the casserole oily.
  • Skipping refrigeration time – The bread won’t fully absorb the egg mixture.
  • Overbaking – Can make the casserole dry and rubbery.

Serving Tips

  • Serve hot, fresh out of the oven with a side of fruit or toast.
  • Pair with a hot cup of coffee or fresh orange juice.
  • Add toppings like salsa, avocado, or sour cream for extra flavor.

Health Benefits of Ingredients

  • Eggs – High in protein and essential vitamins.
  • Sausage – Provides protein but can be substituted with turkey sausage for a leaner option.
  • Cheese – A good source of calcium and healthy fats.
  • Bell peppers – Rich in vitamin C and antioxidants.
