Looking for a make-ahead breakfast that’s hearty, flavorful, and easy to serve on busy mornings? The 7 layer breakfast casserole combines savory ingredients into a satisfying dish that can be prepared in advance and baked fresh when needed. Its layered structure ensures each bite is packed with taste and texture, making it a family favorite or perfect for brunch gatherings.
Ingredients
- 1 lb (450 g) breakfast sausage (pork, turkey, or chicken)
- 1 medium onion, diced
- 1 bell pepper, diced (any color)
- 4 cups frozen hash browns (thawed)
- 2 cups shredded cheddar cheese
- 8 large eggs
- 1 cup milk (whole or 2%)
- 1 teaspoon salt
- ½ teaspoon black pepper
- Optional: ½ teaspoon paprika or smoked paprika for extra flavor
Instructions
- Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with cooking spray or butter.
- Cook the sausage in a large skillet over medium heat until browned and cooked through, about 8-10 minutes. Break it apart into small pieces as it cooks. Remove from heat and drain excess fat.
- In the same skillet, sauté diced onion and bell pepper until softened, about 5 minutes. Mix the cooked sausage with the sautéed vegetables. Spread this mixture evenly across the bottom of the prepared baking dish to form the first layer.
- Sprinkle 1 cup of shredded cheddar cheese evenly over the sausage layer.
- Spread the thawed hash browns evenly over the cheese layer, creating the third layer.
- In a mixing bowl, whisk together eggs, milk, salt, pepper, and optional paprika until well combined. Pour this mixture evenly over all the layers in the baking dish.
- Sprinkle the remaining 1 cup of shredded cheddar cheese on top of the egg mixture.
- Place the casserole in the preheated oven and bake uncovered for 45-50 minutes, or until the eggs are set and the top is golden brown.
- Remove from oven and let it rest for about 5 minutes before slicing and serving.
Tips
- For a vegetarian version, substitute cooked and crumbled tofu or sautéed vegetables for the sausage.
- To make this dish even easier, prepare all layers the night before, cover, and refrigerate. Bake the next morning for a fresh, hot breakfast.
- Ensure the hash browns are thawed to prevent excess moisture, which can make the casserole watery.
- Adjust the cheese and seasoning to suit your taste. Adding hot sauce or chopped green onions can enhance flavor.
Serving Suggestions
Serve the casserole hot, sliced into squares, alongside fresh fruit or a simple green salad for a balanced breakfast. It pairs well with toast or warm muffins for a more filling meal. For a touch of freshness, top with chopped herbs like parsley or chives before serving.
Variations
Change up the ingredients to suit your preferences: use cooked bacon or ham instead of sausage, add sautéed spinach or mushrooms for extra vegetables, or swap the cheddar for Monterey Jack or pepper jack cheese for a different flavor profile. You can also spice it up with hot sauce or diced jalapeños for a kick.
Storage and Reheating
Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, microwave individual portions on high for 1-2 minutes or until heated through. For larger portions, reheat in a 350°F (175°C) oven for about 15-20 minutes, covered with foil to prevent drying out. The casserole can also be frozen for up to 2 months; thaw overnight in the fridge and reheat as described.
Frequently Asked Questions
Can I prepare this casserole the night before?
Absolutely. Assemble all the layers, cover tightly with plastic wrap or foil, and refrigerate overnight. In the morning, simply bake as directed. Just be sure to add a few extra minutes to the baking time if it’s coming straight from the fridge.
Can I make this casserole gluten-free?
Yes. Ensure that the hash browns are labeled gluten-free, and use a gluten-free cheese if needed. The rest of the ingredients are naturally gluten-free, making it suitable for gluten-sensitive diets.
How can I make this dish spicier?
Add diced jalapeños or a dash of hot sauce to the egg mixture. You can also sprinkle red pepper flakes on top before baking for an extra kick.
Is it possible to reduce the fat content?
Yes. Use leaner sausage options, skim milk, and reduce the cheese quantity or opt for reduced-fat cheese. These adjustments will lower the overall fat content while still keeping the dish flavorful.
What if I don’t have hash browns?
You can substitute cooked, shredded potatoes or even diced cooked sweet potatoes. Alternatively, crumbled breakfast sausage with bread cubes can be used to create a different texture and flavor.
Can I freeze this casserole?
Yes. Assemble and bake the casserole, then let it cool completely. Wrap tightly in plastic wrap and foil, and freeze for up to 2 months. Thaw overnight in the fridge and reheat thoroughly before serving.
