Introduction
Mornings can be chaotic, but meal prep can be a game changer. Imagine waking up to a delicious, warm breakfast ready to greet you, fueling your day ahead. That's the beauty of the overnight breakfast casserole.
This dish combines layers of flavors and textures, making it a delightful breakfast option that appeals to everyone. Whether you're hosting a brunch or simply want an easy family meal, this casserole fits the bill perfectly.
Ingredients
- 1 loaf of crusty bread, cubed
The foundation of your casserole, the bread absorbs the egg mixture, creating a custardy texture. Choose a hearty bread like sourdough or whole grain for added flavor and nutrients. - 8 large eggs
Eggs provide the protein and structure for the casserole. They bind all the ingredients together and offer a rich, creamy taste when baked. - 2 cups of milk
Milk enriches the dish, ensuring it stays moist and creamy. You can use whole, skim, or even a non-dairy alternative depending on your preferences. - 1 cup shredded cheese, such as cheddar or mozzarella
Cheese adds a tasty layer of flavor that brings everything together. It melts beautifully, giving that gooey, satisfying texture we love in breakfast dishes. - 1 pound breakfast sausage, cooked and crumbled
Adding sausage not only enhances the flavor but also infuses the casserole with a savory essence, making it a hearty meal option. - 1 cup diced bell peppers
Bell peppers add a pop of color and a sweet crunch. They also provide vitamins that complement the richness of the eggs and cheese. - 1 cup diced onions
Onions contribute depth and sweetness to the casserole. When sautéed, they release their natural sugars, enhancing the overall flavor profile. - 1 teaspoon garlic powder
This adds an aromatic punch without the need for fresh garlic. A hint of garlic complements the other savory ingredients nicely. - 1 teaspoon salt
Essential for enhancing the flavors of your dish, salt balances the richness of the eggs and cheese. - 1/2 teaspoon black pepper
Black pepper adds a touch of heat and complexity to the flavor, rounding out the other ingredients. - 1/4 cup chopped fresh herbs, such as chives or parsley
Fresh herbs brighten the dish with a burst of flavor and color, enhancing the overall presentation and taste.
Directions & Preparation
Step 1: Prepare the bread base.
Start by preheating your oven to 350°F (175°C). Cube your crusty bread and place it evenly in a greased 9×13 inch baking dish. This step is crucial as the bread serves as the base for your casserole, soaking up the egg mixture and creating that beloved custardy texture.
Step 2: Cook and crumble the sausage.
In a skillet over medium heat, cook the breakfast sausage until browned and crumbly. Drain any excess fat and spread the sausage over the bread. This not only imparts a savory flavor but also ensures that each bite is hearty and satisfying.
Step 3: Sauté the vegetables.
In the same skillet, add diced onions and bell peppers, and sauté until softened. This step adds an additional layer of flavor through caramelization, enhancing the sweetness of the onions and the crunch of the peppers.
Step 4: Combine the egg mixture.
In a large bowl, whisk together the eggs, milk, garlic powder, salt, and pepper until well mixed. This mixture is the key to binding the casserole together. The eggs provide protein, while the milk adds creaminess.
Step 5: Layer the ingredients.
Pour the egg mixture over the bread and sausage, ensuring even distribution. Gently press down the bread to soak in the mixture, allowing for a uniform texture once baked.
Step 6: Add cheese and herbs.
Sprinkle the shredded cheese and freshly chopped herbs over the top. This step not only adds flavor but also creates a beautiful golden crust once baked, making the dish visually appealing.
Step 7: Refrigerate overnight.
Cover the dish with foil and refrigerate overnight (or for at least 4 hours). This soaking period is essential for the flavors to meld and for the bread to absorb the egg mixture, resulting in a luscious breakfast.
Step 8: Bake the casserole.
Preheat the oven to 350°F (175°C), uncover the dish, and bake for 45 minutes to an hour, or until the top is golden brown and the center is set. This step is critical as it transforms your ingredients into a cohesive, hearty dish.
Step 9: Cool and serve.
Allow the casserole to cool for a few minutes before slicing. This helps it set up a bit more, making it easier to serve while still warm and inviting. Garnish with additional herbs if desired.

Experiment with Protein Variations
While sausage adds a delicious breakfast flavor, feel free to experiment with other proteins. Try using diced ham, crumbled bacon, or even smoked salmon. Each option will provide a unique flavor twist that can change the entire profile of your casserole.
Vegan-Friendly Alternatives
Adapting this breakfast casserole for a vegan diet is simpler than you might think. Substitute eggs with a mixture of silken tofu blended with a splash of plant-based milk for creaminess. Swap the dairy cheese for a vegan alternative, and use a plant-based sausage to keep it hearty and satisfying.
Perfect Pairings to Elevate Your Meal
To balance the richness of the casserole, consider serving it with a light side, such as a fresh fruit salad or yogurt. A tangy slice of citrus or a sweet berry compote can bring a refreshing contrast to the dish, enhancing your breakfast experience.
FAQs
What if my casserole ends up watery?

You can substitute cheddar with any cheese you prefer, like feta for a tangy twist or pepper jack for a spicy kick. Just ensure it melts well.

To make the casserole more filling, consider adding cooked quinoa or a layer of spinach. Both ingredients will enhance the nutrition without overpowering flavors.
Can I prepare this dish for a large gathering?
You can easily scale up the recipe by doubling the ingredients and using a larger baking dish. Just make sure to adjust the baking time accordingly.
