Ingredients

Scale

Protein:

  • 1 pound (454 grams) Italian sausage (mild or spicy)
  • 6 large eggs

Vegetables:

  • 1 small onion, diced
  • 1 small red bell pepper, diced
  • 1 small green bell pepper, diced

Dairy and Bread:

  • 2 cups (480 milliliters) milk
  • 6 slices white or Italian bread, cut into cubes
  • 1 ½ cups (170 grams) shredded mozzarella cheese
  • ½ cup (50 grams) grated Parmesan cheese

Seasonings:

  • 1 teaspoon salt
  • ½ teaspoon ground black pepper

Instructions

  1. Prepare the oven by heating to 350F (175C) for optimal cooking temperature.
  2. Sauté Italian sausage with finely chopped onions and vibrant bell peppers in a skillet, cooking until meat turns golden brown and vegetables become tender and translucent.
  3. Remove excess oil from the sausage mixture to ensure a lighter, less greasy casserole.
  4. Create a smooth egg base by whisking eggs with milk, seasoning with salt and black pepper until fully integrated.
  5. Generously coat a 9×13-inch baking dish with cooking spray or butter to prevent sticking.
  6. Create a foundational layer by evenly distributing bread cubes across the bottom of the prepared dish.
  7. Distribute the cooked sausage and vegetable mixture uniformly over the bread layer.
  8. Sprinkle a generous layer of mozzarella cheese to add creamy texture and rich flavor.
  9. Carefully pour the prepared egg mixture over the entire casserole, ensuring even coverage.
  10. Finish by dusting the surface with grated Parmesan cheese for an extra savory touch.
  11. Transfer the casserole to the preheated oven and bake uncovered for 45-50 minutes.
  12. Verify doneness by checking that the center is completely set and the top has achieved a golden-brown color.
  13. Allow the casserole to rest for 5-10 minutes, which helps the ingredients settle and makes slicing easier.
  14. Serve warm, cutting into hearty portions that showcase all the delicious layers.
