Equipment

  • 1 Large Skillet
  • 1 Cutting Board
  • 1 Chef’s Knife
  • 1 Large mixing bowl
  • 1 Whisk
  • 1 Measuring Cups
  • 1 Measuring Spoons
  • 1 9x13-inch baking dish
  • 1 Wooden spoon or spatula
  • 1 Aluminum foil, optional

Ingredients

  • Main Ingredients
  • 1 lb breakfast sausage
  • 1 lg large eggs
  • 2 cups milk
  • 4 cups cubed day-old bread
  • Cheese & Base
  • 1 tbsp Butter or Cooking Spray (for greasing baking dish)
  • 2 cups shredded cheddar cheese
  • 1/2 cups shredded mozzarella cheese
  • 1/2 medium yellow onion diced
  • 1 medium bell pepper diced, optional
  • Seasonings & Finish
  • 1/2 tsp salt
  • 1/2 tsp black pepper
  • 1/2 tsp garlic powder
  • 1 tbsp chopped fresh parsley optional for garnish

Instructions

  • Preheat oven to 350°F. Grease a 9x13-inch baking dish with cooking spray or a light coating of butter.
    1 tbsp Butter or Cooking Spray
  • Heat a large skillet over medium heat. Add the breakfast sausage and cook until browned and fully cooked, breaking it into crumbles as it cooks.

  • Add the diced onion and bell pepper to the skillet. Cook for 3–4 minutes, until softened. Drain excess grease from the skillet.

  • In a large mixing bowl, whisk together the eggs, milk, salt, black pepper, and garlic powder until smooth and fully combined.
    1 lg large eggs, 2 cups milk, 1/2 tsp salt, 1/2 tsp black pepper, 1/2 tsp garlic powder
  • Spread the cubed bread evenly in the prepared baking dish. Spoon the sausage mixture over the bread, then sprinkle the cheddar cheese and mozzarella cheese evenly over the top.

  • Pour the egg mixture evenly over the casserole. Gently press the bread down with a spatula so it can absorb the liquid.
    1 lg large eggs
  • Let the casserole sit for 10–15 minutes before baking, or cover and refrigerate overnight for a make-ahead option.
  • Bake uncovered for 40–45 minutes, or until the center is set and the top is golden brown. If the top browns too quickly, cover loosely with foil.
  • Let the casserole rest for 5–10 minutes before slicing. Garnish with parsley if desired and serve warm.
    1 tbsp chopped fresh parsley

Notes

  • Day-old bread works best because it absorbs the egg mixture without becoming too soggy.
  • If using fresh bread, cube it and let it sit out for a few hours before assembling.
  • Drain the sausage well so the casserole stays rich but not greasy.
  • For a spicier version, use hot sausage or add red pepper flakes.
  • For a lighter version, use turkey sausage and reduced-fat cheese.
  • To make ahead, assemble the casserole, cover tightly, and refrigerate overnight. Bake the next day as directed.
  • Let the casserole rest after baking so it slices cleanly.
