Cheesy breakfast sausage casserole is the ultimate morning comfort food. Packed with savory sausage, fluffy eggs, gooey cheese, and buttery bread, this make-ahead dish is perfect for holidays, brunches, or lazy weekends.
Ingredients
- 1 lb breakfast sausage (mild or spicy)
- 6 large eggs
- 2 cups whole milk
- 1 tsp Dijon mustard
- 1/2 tsp garlic powder
- 1/2 tsp salt
- 1/4 tsp black pepper
- 4 cups cubed bread (French bread or sourdough, about 1-inch pieces)
- 1 1/2 cups shredded cheddar cheese
- 1/2 cup shredded mozzarella cheese
- 2 green onions, sliced (optional, for garnish)
Instructions
- Cook the Sausage:
- In a large skillet, cook the breakfast sausage over medium heat until browned and fully cooked. Drain any excess grease and set aside.
- Prepare the Egg Mixture:
- In a large mixing bowl, whisk together the eggs, milk, Dijon mustard, garlic powder, salt, and black pepper.
- Assemble the Casserole:
- Grease a 9×13-inch baking dish. Spread the cubed bread evenly in the dish. Sprinkle the cooked sausage and 1 cup of cheddar cheese over the bread.
- Pour the egg mixture evenly over the top, ensuring the bread is well soaked. Press the bread down gently to absorb the liquid.
- Top with Cheese:
- Sprinkle the remaining cheddar cheese and mozzarella cheese evenly over the casserole.
- Refrigerate (Optional):
- For best results, cover and refrigerate the casserole for at least 2 hours or overnight. This allows the flavors to meld and the bread to absorb the egg mixture.
- Bake the Casserole:
- Preheat your oven to 350°F (175°C). Remove the casserole from the refrigerator and let it sit at room temperature for 15 minutes.
- Bake uncovered for 40-45 minutes, or until the top is golden brown and the center is set.
- Serve:
- Let the casserole cool for 5 minutes before slicing. Garnish with green onions if desired. Serve warm and enjoy!
Tips for the Best Breakfast Casserole
- Make It Your Own: Add sautéed mushrooms, bell peppers, or spinach for extra flavor and nutrition.
- Use Day-Old Bread: Slightly stale bread works best as it absorbs the egg mixture without becoming mushy.
- Spice It Up: Use spicy sausage or add red pepper flakes for a kick.
- Freeze for Later: Assemble and freeze the unbaked casserole. Thaw overnight in the fridge and bake as directed.
