Ingredients You’ll Need

1 pound pork sausage: This adds rich flavor and protein. Ground turkey or chicken sausage can be a great alternative for a lighter option.
10 large eggs, lightly beaten: Essential for fluffiness, eggs bind the casserole. Make sure they are at room temperature for the best results.
3 cups milk: Using whole milk can make the casserole creamier. Almond or oat milk can serve as dairy-free alternatives.
1 teaspoon fine sea salt: To enhance the dish’s overall flavor. Adjust based on your taste preferences.
½ teaspoon black pepper: Adds a mild kick; feel free to increase for more heat.
6 cups cubed bread: A day-old French or Italian bread gives the best texture. You can also use gluten-free bread for a different option.
2 cups shredded sharp cheddar cheese: For that gooey, cheesy goodness. Other cheeses like Monterey Jack or Gruyère work well too.
½ cup diced red pepper (optional): Adds a pop of color and a hint of sweetness. Skip it if you prefer a meatier casserole.
Sliced green onion (optional): For a fresh topping that adds a touch of brightness when serving.

Prepare the casserole dish: Grease a 9x13x2-inch casserole dish to ensure an easy release.
Cook the sausage: In a large skillet, cook 1 pound of pork sausage over medium-high heat. Stir frequently until it’s thoroughly cooked and no longer pink. This step fills the kitchen with a delicious aroma!
Whisk together eggs and milk: In a large bowl, whisk together 10 lightly beaten eggs, 3 cups of milk, and 1 teaspoon of fine sea salt until well-combined. The mixture should be smooth and creamy.
Layer the ingredients: Evenly distribute half of the 6 cups of cubed bread into the prepared casserole dish. Sprinkle with half of the 2 cups of shredded sharp cheddar cheese, half of the ½ teaspoon black pepper, half of the optional diced red pepper, and half of the cooked sausage. Repeat these layers for a well-rounded flavor profile.
Add the egg mixture: Pour the egg mixture evenly over the layers in the casserole dish. Make sure it penetrates all the way down for an even bake.
Refrigerate or bake immediately: You can cover and refrigerate the casserole overnight to let the flavors meld together, or bake it right away. If you choose to refrigerate, this allows for a quick breakfast the next day!
Bake to perfection: When you’re ready to bake, preheat your oven to 325°F. Bake uncovered for 60-75 minutes, or until the eggs are set. If the top browns too quickly, loosely cover the casserole dish with foil to prevent burning.
Serve and enjoy: If desired, sprinkle with sliced green onions before serving warm. Your guests will be delighted by the aromas and flavors!

Storing & Reheating

To store leftover breakfast casserole, allow it to cool completely at room temperature, then transfer it to an airtight container. Refrigerate for up to 3-4 days. If you want to keep it for a longer period, you can freeze the casserole for up to 3 months. Make sure to wrap it tightly in plastic wrap or aluminum foil. When ready to enjoy, simply reheat in the oven at 350°F for about 25-30 minutes or until heated through. Note that freezing may alter the texture slightly, but for an added boost of freshness, consider adding a sprinkle of fresh cheese before reheating.

Chef’s Helpful Tips

Be sure to cook the sausage thoroughly; any pink may indicate it’s not done.
Use day-old bread to avoid a soggy casserole. Fresh bread can absorb too much moisture.
If you’re short on time, you can prepare the casserole in the morning and bake it before guests arrive.
Feel free to experiment with ingredients! Spinach or other vegetables can easily be added for extra nutrition.
For a more luxurious flavor, try mixing in some cream cheese or sour cream with the egg mixture.
Always let the casserole sit for a few minutes before serving; this will help it firm up for cleaner slices.

Breakfast casseroles are the ultimate way to kick off a special morning. This make-ahead breakfast casserole is the epitome of ease and flavor—an approachable yet flavorful solution to brunching at home. Not only does it save time and stress, but it also brings a sense of togetherness as loved ones gather around to share in the warm, delicious bounty you’ve created.

Recipe FAQs

Can I make this breakfast casserole vegetarian?

Absolutely! Simply omit the sausage and add veggies like spinach, mushrooms, or zucchini instead. You could also substitute in a meat alternative for a similar texture.

Can I prepare this breakfast casserole the night before?

Yes! That’s the beauty of this recipe. You can assemble all the layers the night before and refrigerate. Just remember to increase the baking time if it’s coming straight from the fridge.

What can I substitute for cheddar cheese?

While sharp cheddar is the star of the show, feel free to mix things up with cheeses like mozzarella, Monterey Jack, or even feta for a unique twist.

How do I know when the casserole is done baking?

The casserole is done when the edges are golden and the center is set; you can test it with a toothpick to ensure that it comes out clean from the center. If it’s still wet, give it more time!
