Description

Savor hearty Italian sausage breakfast casserole that blends robust flavors of spicy sausage, eggs, and melted cheese. Comfort meets convenience in this easy one-pan morning delight you’ll crave from first bite to last.


Ingredients

Scale
  • 1 pound (454 g) Italian sausage (mild or spicy)
  • 1 ½ cups (170 g) shredded mozzarella cheese
  • ½ cup (50 g) grated Parmesan cheese
  • 6 large eggs
  • 6 slices white or Italian bread, cut into cubes
  • 2 cups (480 ml) milk
  • 1 small onion, diced
  • 1 small red bell pepper, diced
  • 1 small green bell pepper, diced
  • 1 tsp salt
  • ½ tsp ground black pepper

Instructions

  1. Sausage Sauté: Brown Italian sausage with onions and bell peppers in a skillet over medium heat, thoroughly draining any excess fat to ensure a crisp, flavorful base.
  2. Egg Preparation: Whisk eggs with milk, salt, and black pepper in a large mixing bowl until smooth and well-combined, creating a rich custard foundation.
  3. Layering Foundation: Generously grease a 9×13-inch baking dish, then evenly distribute bread cubes across the bottom, forming a rustic, textured base.
  4. Protein and Vegetable Distribution: Spread the sautéed sausage and vegetable mixture uniformly over the bread cubes, ensuring balanced coverage.
  5. Cheese Infusion: Sprinkle mozzarella cheese across the surface, followed by a generous coating of grated Parmesan for added depth and complexity.
  6. Custard Incorporation: Gently pour the egg mixture over the entire casserole, allowing it to seep into all layers and create a cohesive, custardy texture.
  7. Baking Process: Place in a preheated 350°F (175°C) oven and bake uncovered for 45-50 minutes, watching for a golden-brown top and a firmly set center.
  8. Resting and Serving: Allow the casserole to rest for 5-10 minutes, which helps it set and makes slicing easier, then serve hot and enjoy.

Notes

  • Remove excess grease completely from sausage and vegetables to prevent a soggy casserole base and maintain crisp texture.
  • Use day-old or slightly stale bread cubes to absorb egg mixture without becoming too mushy, ensuring perfect consistency.
  • Sprinkle cheeses evenly for uniform flavor and melting, creating a balanced bite in every serving.
  • Ensure casserole reaches internal temperature of 160°F to guarantee eggs are fully cooked and sausage is safe to consume.
