Directions: Sausage Breakfast Casserole
1. Preheat the oven to 350°F (175°C). This ensures that your casserole cooks evenly, resulting in a perfectly golden-brown top.
2. Cook the crumbled sausage in a skillet over medium heat until browned. Stir occasionally for about 5-7 minutes, allowing those delicious flavors to develop.
3. Whisk together the eggs and milk in a mixing bowl until well combined. This mixture creates a fluffy base for your hearty casserole.
4. Combine the cooked sausage, cubed bread, and shredded cheese into the egg mixture. Gently fold everything together to ensure every piece is coated with that tasty egg blend.
5. Pour the mixture into a greased baking dish, spreading it out evenly. This allows for consistent cooking, so every bite is just as delightful as the last.
6. Bake for 30 minutes or until the casserole is set and golden brown on top. You’ll know it’s ready when the edges start to pull away slightly from the dish.
Optional: Garnish with fresh herbs like parsley for a pop of color and flavor!

Simply store the mixture in the refrigerator until you’re ready to bake it. When you’re ready to serve, preheat your oven to 350°F (175°C), pour the mixture into a greased baking dish, and bake for 30 minutes or until it’s set and golden brown.
