How To Make Breakfast Casserole
Preheat the oven to 375 degrees F. Brown the sausage in a skillet until no longer pink. Remove from the skillet and set aside.
Add butter to the pan and brown the hash browns in the same skillet you used to cook the sausage. This step is optional but adds more flavor and texture to the sausage-and-egg casserole. Skip this step if you are making the casserole ahead of time.
Mix together milk, eggs, Bisquick, salt, and pepper in a bowl. It will be slightly lumpy because of the Bisquick.
Add the sausage to the casserole dish and top with hashbrowns (cooked or frozen). Then top with egg mixture and a sprinkle of cheese.
Bake in the oven for 45 – 55 minutes or until the eggs are all cooked. Add extra cheese during the last 5-10 minutes of baking. Serve hot and enjoy!




What can I add to sausage and egg casserole?
- Vegetables: You can add vegetables like diced bell peppers, onions, mushrooms, spinach, or zucchini to the casserole. Sauté the vegetables first to remove excess moisture.
- Cheese: You can add shredded cheese to the casserole for added creaminess and flavor. We use cheddar, but Monterey Jack, Mozzarella, and Parmesan are all good choices.
- Herbs and Spices: You can add herbs and spices such as thyme, rosemary, paprika, or cumin to the casserole to add more depth of flavor.
- Bread: You can add bread to the casserole to make it more filling. Cut a few slices of bread into small cubes and add them to the casserole before baking.
- Hot Sauce: If you like a little heat, you can add a few dashes of hot sauce to the casserole before baking.
- Bacon: You can add crumbled bacon to the casserole for a smoky flavor.
- Ham: Diced ham is another great addition to a sausage-and-egg casserole.
- Sour cream: You can add a dollop to the casserole before serving for a creamy finish.
What goes with breakfast casserole?
- Fresh Fruit: Serve the breakfast casserole with a side of fresh fruit such as berries, sliced oranges, or sliced bananas.
- Toast or Bagels: A slice of toast or a toasted bagel can be a great side dish.
- Hash Browns: Crispy hash browns are a classic side dish for breakfast, and they go well with this sausage and egg casserole.
- Biscuits: Freshly baked biscuits are a perfect pairing for a breakfast casserole, especially if the casserole has a lot of gravy or sauce.
- Yogurt: A side of yogurt can provide a creamy contrast to the savory flavors of a breakfast casserole.
How do you make breakfast casserole in advance?
Follow all the recipe directions, except don’t cook the hash browns. Add all of the ingredients to the casserole dish, cover tightly, and refrigerate for up to 24 hours in advance.
