Crafting Your Perfect Overnight Breakfast Casserole

This recipe provides a classic base that you can easily adapt. We'll focus on a savory version packed with sausage, cheese, and bread, but remember the possibilities are endless!

Yields: 6-8 servings

Prep time: 20 minutes (the night before)

Bake time: 45-55 minutes

Ingredients:

1 lb breakfast sausage, cooked and crumbled (or bacon, ham, or vegetarian sausage)
6-8 slices day-old bread, cut into 1-inch cubes (sourdough, brioche, or white bread work well)
2 cups shredded cheese (cheddar, Monterey Jack, or a blend)
1/2 cup chopped onion (optional)
1/2 cup chopped bell pepper (optional)
8 large eggs
2 cups milk (any kind)
1 teaspoon dry mustard (enhances savory flavor)
1/2 teaspoon salt
1/4 teaspoon black pepper
Pinch of red pepper flakes (optional, for a kick)
Butter or cooking spray for greasing the dish

Equipment:

9x13 inch baking dish
Large mixing bowl

Instructions:

Cook the Meat (and Veggies): If using, cook the breakfast sausage in a skillet over medium heat until browned and crumbled. Drain any excess grease. If adding onion and bell pepper, sauté them in the same pan until softened.
Assemble the Base: Lightly grease your 9x13 inch baking dish. Spread the cubed bread evenly across the bottom of the dish. Layer the cooked sausage (and veggies, if using) over the bread. Sprinkle 1.5 cups of the shredded cheese evenly over the sausage layer.
Prepare the Egg Mixture: In a large mixing bowl, whisk together the eggs, milk, dry mustard, salt, pepper, and red pepper flakes (if using) until well combined.
Pour and Chill: Evenly pour the egg mixture over the layers in the baking dish, making sure the bread is fully soaked. Gently press down any floating bread pieces to ensure they absorb the liquid. Cover the dish tightly with plastic wrap and refrigerate for at least 4 hours, or preferably overnight (up to 12-18 hours). This chilling time is crucial for the bread to absorb the egg mixture and for the flavors to meld.
Bake the Next Morning: Preheat your oven to 350°F (175°C). Remove the casserole from the refrigerator and uncover it. Sprinkle the remaining 1/2 cup of shredded cheese over the top.
Bake until Golden: Bake for 45-55 minutes, or until the casserole is golden brown, puffed, and the center is set. A knife inserted into the center should come out clean. If the top starts to brown too quickly, you can loosely cover it with foil.
Rest and Serve: Let the casserole rest for 5-10 minutes before slicing and serving. This allows it to set up properly.

Customization Ideas for Your Casserole

Vegetarian: Omit the meat and add sautéed spinach, mushrooms, sun-dried tomatoes, or extra bell peppers.
Sweet Version: Use challah or brioche bread, omit the savory ingredients, and add fruit (berries, apples), cinnamon, nutmeg, and a drizzle of maple syrup or a brown sugar streusel topping.
Spice It Up: Add diced jalapeños, a dash of hot sauce to the egg mixture, or use pepper jack cheese.
Different Cheeses: Experiment with Gruyere, Swiss, or a Mexican blend.
Herbs: Fresh chives, parsley, or thyme can add extra flavor.

Make-Ahead and Storage Tips

Make Ahead: Casserole can be assembled and refrigerated for up to 18 hours.
Leftovers: Store cooled leftovers in an airtight container in the refrigerator for 3-4 days. Reheat in the microwave or oven.
Freezing (Baked): Once completely cooled, cut the casserole into individual portions. Wrap each portion tightly in plastic wrap and then foil. Freeze for up to 1-2 months. Reheat in the oven or microwave from frozen or thawed.

Conclusion

Overnight breakfast casseroles are a game-changer for anyone who loves a hearty breakfast but despises morning rush. With a little bit of prep the night before, you can wake up to the aroma of a delicious, home-cooked meal, making every morning feel a little more special. Say goodbye to rushed breakfasts and hello to stress-free, flavorful mornings!
