Step-by-Step Instructions
Step 1: Prepare Your Workspace and Preheat
Start by preheating your oven to 350°F (175°C). Next, grease a 9×13-inch baking dish with butter or cooking spray. Meanwhile, gather all your ingredients to create an efficient workflow for this Breakfast with Mozzarella.
Step 2: Cook the Italian Sausage
Heat olive oil in a large skillet over medium-high heat. Then, add the Italian sausage, breaking it into bite-sized pieces as it cooks. Cook for 8-10 minutes until browned and cooked through. Subsequently, transfer the sausage to a paper towel-lined plate to drain excess fat.
Step 3: Sauté the Vegetables
Using the same skillet, add diced onion and bell pepper. Cook for 5 minutes until softened. Next, add minced garlic and cook for another minute until fragrant. Finally, stir in cherry tomatoes and cook for 3 minutes until they start to soften.
Step 4: Prepare the Egg Mixture
In a large bowl, whisk together eggs, milk, oregano, red pepper flakes, salt, and pepper. Beat vigorously for 30 seconds to create a smooth, well-combined mixture. This step directly affects the texture of your Italian Breakfast Recipes.
Step 5: Layer the Casserole
First, spread the cubed bread evenly in your prepared baking dish. Then, layer the cooked sausage over the bread. Next, add the sautéed vegetables, distributing them evenly. Finally, sprinkle the ricotta cheese in small dollops across the surface.
Step 6: Add Cheese and Egg Mixture
Sprinkle mozzarella and Parmesan cheeses over the entire casserole. Then, slowly pour the egg mixture over everything, making sure it reaches all corners. Gently press down any bread pieces that float to the surface.
Step 7: Bake to Perfection
Bake for 45-50 minutes until the center is set and the top is golden brown. The internal temperature should reach 160°F (71°C). Additionally, a knife inserted in the center should come out clean.
Step 8: Rest and Garnish
Let the casserole rest for 10 minutes before serving. During this time, sprinkle fresh basil over the top for a burst of color and flavor that completes this Family Italian Brunch masterpiece.
