Now, let’s get cooking! Follow these simple steps to prepare your Easy Overnight Italian Breakfast Casserole.
Step 1: Cook the Sausage
In a large skillet, heat the olive oil over medium heat. Add the uncooked Italian sausage, breaking it apart with a spatula. Cook until browned and fully cooked, about 5-7 minutes. Drain any excess fat.
Step 2: Sauté the Vegetables
Add the diced onion, red bell peppers, and minced garlic to the skillet. Sauté for about 4-5 minutes, or until the vegetables are softened. Stir in the fresh spinach, Italian seasoning, fresh rosemary, salt, and black pepper. Cook until the spinach wilts, about 2-3 minutes. Remove from heat and let it cool slightly.
Step 3: Prepare the Egg Mixture
In a large mixing bowl, whisk together the eggs, full-fat milk, ricotta cheese, and Parmesan cheese until well combined.
Step 4: Combine Ingredients
Add the cooked sausage and vegetable mixture to the egg mixture, stirring gently until everything is well incorporated.
Step 5: Assemble the Casserole
Pour the entire mixture into a greased 9×13 inch baking dish, spreading it out evenly. Cover with aluminum foil and refrigerate overnight, or for at least 4 hours.
Step 6: Bake
Preheat your oven to 350°F (175°C). Remove the casserole from the fridge and let it sit at room temperature for about 15 minutes. Bake, covered, for 30 minutes. Remove the foil and bake for an additional 15-20 minutes, or until the top is golden and a knife inserted in the center comes out clean.
Step 7: Serve and Enjoy!
Allow the casserole to cool for a few minutes before slicing. Serve warm, and enjoy the delightful flavors of your Easy Overnight Italian Breakfast Casserole!
Tailor It to Your Diet
This recipe is easy to modify based on dietary preferences:
- Vegetarian: Replace the Italian sausage with a plant-based sausage or sautéed mushrooms.
- Dairy-Free: Use almond milk and a dairy-free cheese substitute.
- Low-Carb: Omit the ricotta and Parmesan cheese or use a low-carb cheese alternative.
- Gluten-Free: Ensure all ingredients are labeled gluten-free, particularly any pre-packaged items.
Slip-Ups to Skip
When making your Easy Overnight Italian Breakfast Casserole, keep these tips in mind to avoid common mistakes:
- Don’t skip the resting time in the refrigerator; this allows the flavors to meld and ensures a fluffier texture.
- Be sure to fully cook the sausage before adding it to the egg mixture to avoid any food safety issues.
- Don’t rush the baking process; covering the casserole initially helps it cook evenly and prevents the top from burning.
- Make sure to let the casserole cool slightly before cutting to help it hold its shape.
Storing, Freezing & Reheating
After enjoying your Easy Overnight Italian Breakfast Casserole, you may want to store leftovers:
- Refrigeration: Store any leftover casserole in an airtight container in the fridge for up to 4 days.
- Freezing: The casserole can be frozen before baking. Wrap it tightly in plastic wrap and aluminum foil; it will keep for up to 3 months.
- Reheating: To reheat, thaw in the refrigerator overnight if frozen, then bake at 350°F (175°C) until warmed through, about 20-30 minutes.
