How to Make Breakfast Casserole
Step 1
Preheat your oven to 350°F and lightly grease a 9x13-inch baking dish.
Step 2
Cook the breakfast sausage in a large skillet over medium heat until browned and fully cooked. Drain any excess grease before setting the sausage aside.
Step 3
Spread the frozen hash browns evenly across the bottom of the prepared baking dish. Sprinkle the cooked sausage over the potatoes, creating an even layer.
Step 4
In a large bowl, whisk together the eggs, milk, salt, black pepper, and garlic powder until smooth. Pour the egg mixture evenly over the sausage and hash browns so every bite is packed with flavor.
Step 5
Sprinkle the shredded cheddar cheese evenly across the top of the casserole.
Step 6
Bake for 40 to 45 minutes, or until the eggs are fully set and the top is lightly golden.
Step 7
Allow the casserole to rest for about 10 minutes before slicing. Garnish with fresh green onions and serve warm.
What Does Breakfast Casserole Taste Like?
Breakfast casserole combines fluffy baked eggs, savory breakfast sausage, crispy potatoes, and gooey melted cheddar cheese into one comforting dish. Every bite is rich, hearty, and packed with classic breakfast flavors that pair perfectly together.
What to Serve with Breakfast Casserole
Because this casserole already includes eggs, sausage, potatoes, and cheese, it pairs well with lighter breakfast sides. Fresh fruit, homemade pancakes, buttermilk biscuits, crispy bacon, cinnamon rolls, or a fruit salad help round out the meal. For brunch gatherings, serve it alongside coffee, orange juice, or fresh smoothies.
Drink Pairings
A hot cup of coffee is the classic pairing for breakfast casserole, but fresh orange juice, apple juice, iced coffee, strawberry smoothies, or homemade lemonade are also excellent choices depending on the occasion.
Expert Tips
For the best texture, thaw the hash browns before assembling the casserole so excess moisture doesn't collect during baking. Freshly shredded cheddar cheese melts more smoothly than pre-shredded cheese, and allowing the casserole to rest for several minutes before slicing helps it hold together. If you enjoy extra flavor, try adding diced bell peppers, onions, mushrooms, or cooked bacon to the filling.
