Ingredients
- 6 large eggs
- 1 cup whole milk (240 ml)
- 300 g breakfast sausage
- 4 slices white bread, cubed
- 1 ½ cups shredded cheddar cheese (150 g)
- ½ teaspoon salt
- ¼ teaspoon black pepper
- ½ teaspoon garlic powder
- 2 green onions, chopped
Step-by-Step Instructions
1. Preheat the Oven
Start by preheating your oven to 180°C (350°F). This ensures the oven reaches the correct temperature by the time your casserole is assembled.
While the oven heats up, grease a 9×13 inch baking dish with butter or cooking spray. Proper greasing prevents the casserole from sticking and makes cleanup much easier.
2. Cook the Sausage
Place a large skillet over medium-high heat and add the breakfast sausage. Break it apart with a wooden spoon as it cooks.
Cook for about 8-10 minutes until the sausage is browned and no pink remains. Drain any excess grease and set the cooked sausage aside to cool slightly.
3. Prepare the Bread Base
Spread the cubed bread pieces evenly across the bottom of your prepared baking dish. The bread acts as a base layer that absorbs the egg mixture and creates a wonderful texture.
Make sure the bread pieces are distributed in a single, even layer. This helps ensure every bite has the perfect ratio of bread to filling.
4. Add the Sausage and Cheese
Scatter the cooked sausage evenly over the bread cubes. This layering technique ensures every serving gets a good portion of meat.
Next, sprinkle about two-thirds of the shredded cheddar cheese over the sausage layer. Reserve the remaining cheese for topping the casserole before baking.
5. Whisk the Egg Mixture
In a large mixing bowl, crack all six eggs and add the milk. Whisk vigorously until the eggs and milk are completely combined and slightly frothy.
Season the mixture with salt, black pepper, and garlic powder. Give it one more good whisk to incorporate all the seasonings evenly.
6. Pour and Assemble
Slowly pour the egg mixture over the layered ingredients in the baking dish. Use a spatula to gently press down on the bread so it absorbs the liquid.
Sprinkle the remaining cheddar cheese and chopped green onions over the top. The cheese will melt into a beautiful golden crust during baking.
7. Bake to Perfection
Place the casserole in the preheated oven and bake for 45-55 minutes. The casserole is done when the top is golden brown and the center is set.
To test for doneness, insert a knife in the center-it should come out clean. Let the casserole rest for 5-10 minutes before cutting to allow it to set properly.
Tips for Variations or Side Dishes
Vegetarian version: Skip the sausage and add sautéed mushrooms, bell peppers, and spinach instead. This creates a colorful and equally delicious meatless option.
Mexican twist: Use chorizo instead of breakfast sausage and swap cheddar for pepper jack cheese. Top with fresh salsa and sliced avocado after baking.
Low-carb option: Replace the bread cubes with cauliflower florets for a keto-friendly version. Simply blanch the cauliflower first for best results.
Add vegetables: Diced bell peppers, onions, or tomatoes make excellent additions. Just sauté them with the sausage to remove excess moisture.
Perfect side dishes: Serve alongside fresh fruit salad, crispy hash browns, or buttery toast. A simple green salad with light vinaigrette also pairs wonderfully.
Serving Suggestions
Cut the casserole into generous squares and serve directly from the baking dish for a casual family-style breakfast. A large spatula works best for lifting out clean portions.
Garnish each serving with extra chopped green onions or fresh herbs like chives or parsley. A dollop of sour cream or a drizzle of hot sauce adds extra flavor.
This casserole is perfect for brunch gatherings, holiday mornings, or meal prep for busy weekdays. Pair it with fresh orange juice or hot coffee for the complete breakfast experience.
For an elegant presentation, plate individual portions and add a small side salad or fresh berries. The contrast of colors makes for an Instagram-worthy breakfast spread.
FAQ
1. Can I make this casserole ahead of time?
Absolutely! Assemble the entire casserole the night before, cover it tightly with plastic wrap, and refrigerate overnight. In the morning, remove it from the fridge while the oven preheats and add 10-15 extra minutes to the baking time since it will be cold.
2. How should I store leftovers?
Store leftover casserole in an airtight container in the refrigerator for up to 4 days. Reheat individual portions in the microwave for 1-2 minutes or warm the entire dish in a 160°C (325°F) oven until heated through.
3. Can I freeze this breakfast casserole?
Yes, this casserole freezes beautifully for up to 3 months. Wrap it tightly in plastic wrap and aluminum foil before freezing. Thaw overnight in the refrigerator before reheating in the oven.
4. What type of bread works best?
White sandwich bread, French bread, or Texas toast all work wonderfully in this recipe. Day-old bread is actually ideal because it absorbs the egg mixture without becoming too soggy. Avoid using very soft or thin bread slices.
5. Can I use different types of cheese?
Feel free to experiment with your favorite cheeses! Swiss, Gruyère, Monterey Jack, or a blend of Italian cheeses all work well. Mozzarella creates a stretchy, gooey texture while sharp cheddar adds more intense flavor.
