How to Make this Breakfast Casserole Recipe
Executing this mouthwatering meal takes minimal steps, giving you more time to sit and relax. Plus, it can be enjoyed for breakfast, dinner, or anytime you want.
- Prep the Dish and Oven. Spray your 9×13 casserole dish with nonstick spray. Then, preheat your oven to 350 degrees F.
- Cook Sausage and Veggies. Over medium-high heat, brown your ground sausage in a nonstick skillet. Then, add bell peppers and onions and season with salt and pepper. Cook until the pork is no longer pink and the veggies are soft. This should take about 8-10 minutes.
- Drain. Drain the fat from the skillet and add the cooked sausage and vegetables to the casserole dish.
- Add Hashbrowns and Cheese. Sprinkle the frozen hashbrowns and the shredded cheddar over the top of the sausage mixture.
- Prep Eggs. Whisk the eggs and milk in a medium bowl until combined. Next, pour the egg mixture into the casserole dish.
- Cover and Bake. Cover the dish with aluminum foil and bake for about 40-45 minutes.
- Uncover and Finish. Remove the casserole from the oven and take off the aluminum foil. Bake for another 10 minutes or until the top of the egg casserole is slightly browned and the edges come away from the sides of the pan.
- Slice and Serve. Cut into portions, garnish with green onion (optional), and enjoy!
Tips For This Breakfast Casserole Recipe
Here are some quick tips to ensure this recipe always comes out perfectly.
- Cool Before Serving. Let the casserole sit for 5-10 minutes before serving.
- Cook the Meat. Thoroughly. Make sure that the ground sausage is fully cooked before adding it to the casserole. This ensures that you can drain all the fat before baking, keeping it from becoming greasy.
- Make Ahead. You can prepare this breakfast casserole the night before. Store it in the refrigerator and remove it for 30 minutes before you’re ready to bake.
Substitutions and Variations Ideas
Looking for more ways to make this breakfast casserole? Here are some of my favorite ways to jazz it up!
- Breakfast Meat. You can substitute chopped and cooked bacon or ham for the sausage. If you choose, you can add two types of meat. I also like to use the maple variety of the ground sausage for a different flavor.
- Cheese. Use any cheese you like. Pepperjack, swiss, Colby jack, sharp white cheddar, and provolone are also great alternatives.
- Potatoes. Instead of frozen hashbrowns, frozen diced home fries can be used.
- Veggies. Other veggie options include green bell pepper, mushrooms, fresh spinach, or broccoli.
