How to Make breakfast casserole recipe
Making this dish is very straightforward. You will start by browning your meat, whisking your eggs with milk and seasonings, and then layering everything together in a baking dish. It is a simple process of “dump and bake” that results in a gourmet-level breakfast.
Ingredients
- 1 pound ground breakfast sausage (mild or spicy)
- 8 large eggs
- 2 cups whole milk
- 1 teaspoon dry mustard
- 1/2 teaspoon salt
- 1/2 teaspoon black pepper
- 6 cups white or brioche bread, cut into 1-inch cubes
- 2 cups shredded sharp cheddar cheese
- 1/4 cup fresh chives or green onions, chopped (optional for garnish)
Directions
Step 1: Prepare the Oven and Pan
Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with butter or non-stick cooking spray to ensure the casserole doesn’t stick to the sides.
Step 2: Brown the Sausage
Place a large skillet over medium-high heat. Add the ground sausage and cook until it is completely browned and crumbled. Drain off any excess grease and set the meat aside to cool slightly.
Step 3: Layer the Bread and Sausage
Place the cubed bread into the bottom of the prepared baking dish in an even layer. Sprinkle the cooked sausage evenly over the top of the bread cubes. Follow this by sprinkling 1.5 cups of the shredded cheddar cheese over the sausage.
Step 4: Whisk the Egg Mixture
In a large mixing bowl, whisk together the eggs, milk, dry mustard, salt, and pepper until the mixture is smooth and well-combined. Ensure the egg yolks are fully broken and integrated into the milk.
Step 5: Assemble and Bake
Pour the egg mixture slowly over the bread, sausage, and cheese in the baking dish. Press down lightly with a spatula to make sure all the bread is submerged. Sprinkle the remaining 1/2 cup of cheese on top. Bake for 40 to 45 minutes, or until the eggs are set and the top is golden brown. Let it rest for 5 to 10 minutes before slicing.
How to Serve breakfast casserole recipe
Serve this casserole warm, straight from the oven. It looks beautiful when garnished with fresh chives or sliced green onions for a pop of color. For a complete brunch spread, pair it with a side of fresh fruit, some crispy hash browns, or a light green salad. It also goes wonderfully with a dash of hot sauce or a dollop of salsa for those who like a bit of a kick.
How to Store breakfast casserole recipe
If you have leftovers, they store very well. Place them in an airtight container and keep them in the refrigerator for up to 3 to 4 days. To reheat, you can use the microwave for a quick meal or put a slice in the oven at 350°F until warmed through. This casserole can also be frozen for up to 2 months; just wrap individual slices tightly in foil and plastic wrap.
Expert Tips for Perfect breakfast casserole recipe
For the best texture, use bread that is a day or two old. Slightly stale bread absorbs the egg mixture better without becoming too mushy. If you are using fresh bread, you can lightly toast the cubes in the oven for a few minutes before assembling. Also, don’t be afraid to experiment with different cheeses like Gruyere or Pepper Jack for a different flavor profile.
Delicious Variations
You can easily swap the sausage for chopped bacon, diced ham, or even vegetarian sausage crumbles. To add more nutrients, try mixing in sautéed bell peppers, onions, spinach, or mushrooms. For a Mexican-inspired twist, use chorizo and top the finished casserole with avocado and cilantro. If you prefer a lower-carb version, you can replace the bread with tater tots or even steamed cauliflower florets.

Frequently Asked Questions
Q: Can I make this casserole ahead of time?
Yes! In fact, it is recommended. You can assemble the entire dish, cover it with plastic wrap, and let it sit in the fridge overnight. Just take it out of the fridge 20 minutes before baking so it reaches room temperature.
Q: What kind of bread works best?
Thick-cut white bread, Brioche, or Challah work best because they are sturdy and soak up the liquid well. Sourdough is also a great option if you like a bit of tang.
Q: Can I use skim milk instead of whole milk?
You can, but the casserole will not be as rich or creamy. Whole milk or even a splash of heavy cream provides the best custard-like texture for the eggs.
Q: How do I know when the casserole is finished baking?
The center should be firm to the touch and not “jiggle” when you move the pan. A knife inserted into the center should come out clean, and the edges should be bubbling and golden.
Q: Can I double this recipe?
Absolutely. If you are feeding a very large crowd, you can double the ingredients and use two 9×13 pans. Be sure to check your oven space to ensure even air circulation while baking.
