How to Make Sausage and Egg Casserole
1. Cook the Sausage
In a skillet over medium heat, brown the sausage, breaking it into crumbles. Drain excess grease and set aside.
2. Prepare the Egg Mixture
In a large bowl, whisk together the eggs, milk, and seasonings until well combined.
3. Assemble the Casserole
Grease a baking dish. Layer the cooked sausage, bread cubes (if using), and shredded cheese evenly. Pour the egg mixture over the top.
4. Bake
Bake in a preheated 375°F (190°C) oven for 30–40 minutes, or until the center is set and the top is lightly golden.
5. Rest and Serve
Let the casserole rest for about 5 minutes before slicing. Serve warm.
