This recipe is as easy as it is satisfying, making it an ideal choice for meals with family or a special brunch with friends.

Ingredients

  • 12 large eggs
    Eggs form the base of the casserole, providing structure and protein. They also help bind the other ingredients together, resulting in a cohesive dish that is both filling and nutritious.
  • 2 cups milk
    Milk adds moisture to the casserole, ensuring that the texture remains creamy and rich. It also contributes to the overall flavor, enhancing the taste of the eggs and other ingredients.
  • 1 pound of bread (such as French or challah), cubed
    Cubed bread acts as a canvas, soaking up the egg and milk mixture. It creates a delicious, custardy texture that complements the other savory flavors in the casserole.
  • 2 cups shredded cheese (cheddar or your choice)
    Cheese introduces a creamy, savory element that adds depth to the casserole. It also creates a tempting golden top as it melts and bubbles during baking.
  • 1 pound cooked sausage or bacon, crumbled
    Adding cooked sausage or bacon infuses the dish with rich flavors and hearty protein. Choose your favorite type to personalize the dish according to your tastes.
  • 1 cup diced bell peppers
    Bell peppers lend a fresh crunch and a hint of sweetness, balancing out the richness of the eggs and meat. They also add vibrant color to the casserole.
  • 1 cup diced onion
    Onions contribute a savory depth and natural sweetness to the dish. Their flavor becomes mellow and caramelized during baking, enriching the overall taste.
  • 2 teaspoons dried mustard
    Dried mustard adds a subtle tang and depth to the casserole, enhancing the flavor without overwhelming the other ingredients. It also brings a hint of sophistication.
  • Salt and pepper to taste
    Seasoning is essential to elevate all the flavors in your casserole. Adjust the salt and pepper based on personal preference to maximize taste.

Directions & Preparation

Step 1: Preheat your oven to 350°F (175°C).

Preheating your oven ensures even cooking and helps achieve a perfectly baked casserole. An adequately heated oven allows the eggs to set correctly and the cheese to melt beautifully, creating that desirable golden top.

Step 2: In a large mixing bowl, whisk together the eggs and milk until well combined.

Whisking the eggs and milk thoroughly ensures that the mixture is uniform, allowing the flavors to meld smoothly. This step is critical for a light and airy texture in the final dish.

Step 3: Add diced bread to the egg mixture, gently folding to coat.

Folding the bread into the egg mixture allows each piece to absorb the liquid without breaking apart. Properly coating the bread is key to achieving a custard-like texture in the finished casserole.

Step 4: Stir in cooked sausage or bacon, bell peppers, onions, mustard, salt, and pepper.

This step integrates all the flavorful components of the casserole. The combination of ingredients ensures that every bite is packed with taste, balancing richness and freshness.

Step 5: Transfer the mixture into a greased 9×13 inch baking dish, spreading it evenly.

Evenly spreading the mixture in the baking dish promotes uniform cooking throughout the casserole. Use a spatula to ensure that ingredients are evenly distributed for consistent flavor and texture.

Step 6: Cover the dish with aluminum foil and refrigerate overnight.

Allowing the casserole to rest overnight gives the bread ample time to soak up the egg mixture and the flavors to meld. This preparation step not only saves time in the morning but also enhances the overall taste.

Step 7: In the morning, remove the casserole from the refrigerator and let it sit at room temperature for about 30 minutes before baking.

Letting the casserole warm up slightly before baking helps in achieving even cooking. It prevents the shock of temperature change, leading to a more consistent texture throughout.

Step 8: Bake uncovered for 45-55 minutes or until the top is golden brown and the center is set.

Baking uncovered allows the casserole to develop a beautiful, golden crust while ensuring the insides are cooked thoroughly. To check, insert a knife in the center; it should come out clean when done.

Step 9: Let the casserole cool for a few minutes before serving, then slice into squares and enjoy!

Allowing the casserole to cool slightly helps it set, making it easier to slice. Taking this time ensures that each portion holds its shape and is easy to serve, enhancing your breakfast experience.

Perfect Pairings

Making it a Meal

For a more filling breakfast, consider integrating sides like roasted potatoes or avocado toast.

Each addition allows you to tailor your breakfast spread according to your energy needs and taste preferences.

FAQs

What if my casserole is too dry?

You can add more milk or an additional egg to the mixture before baking. If it's dry after baking, serving it with a side of salsa or a creamy sauce can help add moisture.

Can I prepare this casserole without meat?

Absolutely! Simply omit the meat and add more vegetables or extra cheese for flavor. This can be a delightful vegetarian option.

How can I make this casserole spicier?

Consider adding jalapeños, red pepper flakes, or hot sauce into the mixture for a kick. Experiment with levels of spice according to your taste.

Is there a way to scale the recipe for a larger gathering?

Yes, simply double the ingredients and use a larger baking dish. You may need to adjust the baking time slightly to ensure it cooks through.

What can I do if my casserole isn’t setting in the middle?

If the casserole remains jiggly after baking, it may need more time in the oven. Cover it with foil and continue baking, checking every 5-10 minutes until set.

How can I replace dairy in this recipe?

You can use almond milk or oat milk instead of regular milk and opt for dairy-free cheese to create a lactose-free version while maintaining flavor.
