Ingredients

• 1 pound Italian sausage
• 1 tablespoon Olive oil
• 1 medium Yellow onion, diced
• 1 medium Red bell pepper, diced
• 2 cloves Garlic, minced
• 2 cups Baby spinach
• 10 Large eggs
• 0.5 cup Milk
• 1.5 cups Shredded mozzarella cheese
• 0.5 cup Shredded Parmesan cheese
• 1 teaspoon Salt
• 0.5 teaspoon Black pepper
• 1 teaspoon Dried Italian seasoning
• 4 cups Day-old bread, cubed
• 2 tablespoons Fresh basil (optional, for garnish)

Directions

Step 1

Preheat your oven to 375°F (190°C) and grease a 9x13-inch baking dish with butter or non-stick spray.

Step 2

In a skillet over medium heat, cook the Italian sausage until browned and fully cooked, breaking it into small crumbles. Remove from skillet and set aside.

Step 3

In the same skillet, heat olive oil and sauté the diced onion and red bell pepper until softened, about 4-5 minutes. Add the minced garlic and cook for 1 additional minute until fragrant.

Step 4

Stir in the baby spinach and cook until wilted, about 2 minutes. Remove from heat.

Step 5

In a large mixing bowl, whisk together the eggs, milk, salt, pepper, and dried Italian seasoning.

Step 6

Fold in the cooked sausage, sautéed vegetables, cubed bread, 1 cup of mozzarella cheese, and 1/4 cup of Parmesan cheese into the egg mixture. Mix until the bread is evenly coated.

Step 7

Pour the mixture into the prepared baking dish and spread evenly. Top with the remaining 1/2 cup of mozzarella and 1/4 cup of Parmesan cheese.

Step 8

Cover the dish with aluminum foil and bake in the preheated oven for 25 minutes. Then, remove the foil and bake for an additional 20 minutes, or until the casserole is set and the top is golden brown.

Step 9

Remove from the oven and let the casserole rest for 5 minutes before serving. Garnish with fresh basil, if desired.

Step 10

Slice into portions and serve warm. Enjoy your delicious Italian Breakfast Casserole!
