Step-by-Step Instructions
Preheat Oven and Prepare Baking Dish:
Preheat your oven to 350°F (175°C). Lightly grease an 8×8 inch baking dish with butter or cooking spray. This step ensures your casserole won’t stick and will release easily after baking.Cook the Sausage:
In a large skillet over medium heat, add the breakfast sausage. Break it up with a spoon as it cooks. Cook until the sausage is browned and no pink remains. If you’re using chopped onion, add it during the last 5 minutes of cooking the sausage, allowing it to soften and become fragrant. Once cooked, drain any excess grease from the skillet.Assemble the Casserole Base:
Spread the cooked sausage (and onion, if used) evenly in the bottom of the prepared baking dish.Prepare the Egg Mixture:
In a medium bowl, whisk together the eggs, milk, salt, and pepper until well combined and slightly frothy. This creates the creamy base for your casserole.Add Cheese:
Sprinkle half of the shredded cheddar cheese evenly over the sausage mixture in the baking dish.Pour Egg Mixture:
Carefully pour the egg mixture over the sausage and cheese, ensuring it distributes evenly throughout the dish.Top with Remaining Cheese:
Sprinkle the remaining shredded cheddar cheese over the top of the egg mixture. This will create a beautiful golden-brown crust as it bakes.Bake the Casserole:
Place the baking dish in the preheated oven. Bake for 30-35 minutes, or until the casserole is set in the center and the top is golden brown and bubbly. You can test for doneness by inserting a knife near the center; it should come out clean.Rest Before Serving:
Remove the casserole from the oven and let it rest for about 5-10 minutes before slicing and serving. This allows the casserole to set fully, making it easier to cut into neat portions.

Storing and Reheating Tips
Properly storing your Easy Sausage and Egg Casserole leftovers is key to enjoying its deliciousness throughout the week.
Refrigeration: Allow the casserole to cool completely. Once cooled, cover the baking dish tightly with plastic wrap or aluminum foil, or transfer individual portions into airtight containers. It can be stored in the refrigerator for up to 3-4 days.
Freezing: For longer storage, you can freeze the cooled casserole. You can freeze the entire dish or individual portions in freezer-safe containers or wrap them tightly in plastic wrap and then aluminum foil. Frozen casserole is best consumed within 1-2 months for optimal quality.
Reheating:
- From Refrigerator: To reheat, place a portion in a microwave-safe dish and microwave on medium power, in 30-second intervals, until heated through. Alternatively, you can reheat individual portions or the entire casserole in a preheated oven at 325°F (160°C) until warm, usually about 15-20 minutes for portions, longer for a larger dish.
- From Freezer: Thaw the frozen casserole overnight in the refrigerator before reheating using oven methods. For quicker reheating, you can try reheating directly from frozen in a 325°F (160°C) oven, but this may take longer, and the texture might be slightly less ideal than when thawed.
