Step-by-Step Instructions for Overnight Italian Breakfast Casserole

Preheat your oven to 350°F (175°C) and grease a 9x13 inch casserole dish with olive oil or cooking spray.
In a skillet over medium heat, cook the Italian sausage until browned, about 5-7 minutes. Stir in Italian seasoning and rosemary.
In the same skillet, sauté onions and red bell peppers until soft, about 6 minutes. Add spinach and garlic, cooking for an additional 2 minutes.
Return the cooked sausage to the skillet, mixing with the sautéed vegetables until well combined.
Whisk together eggs, milk, ricotta cheese, and parmesan cheese until smooth. Set aside to thicken.
Layer half of the sausage-vegetable mixture in the greased casserole dish, followed by half of the egg mixture. Repeat layering.
Cover with plastic wrap and refrigerate overnight, or bake immediately for 55 minutes until set.
Allow the casserole to cool for about 10 minutes before slicing and serving.
