How to Make Overnight Breakfast Casserole

Step 1: Prepare Your Ingredients

Start by cubing your bread or prepping your hash browns and chopping any vegetables or meats you plan to include. Having everything ready makes assembly smooth and quick.

Step 2: Mix the Egg Base

In a large bowl, whisk together eggs and milk or cream until well combined. Season generously with salt, pepper, and your preferred herbs and spices to infuse flavor right from the start.

Step 3: Combine All Ingredients

Layer your bread or potatoes at the bottom of your baking dish, then evenly distribute meat and vegetables on top. Pour the egg mixture over everything, making sure it soaks through. Sprinkle cheese on top for that golden finish.

Step 4: Refrigerate Overnight

Cover the casserole tightly with plastic wrap or foil and place it in the refrigerator overnight. This allows the flavors to meld and the bread or potatoes to absorb the egg custard fully.

Step 5: Bake and Enjoy

The next morning, pop the casserole into a preheated oven and bake until the top is golden and the center is set, typically around 45-60 minutes. Let it cool slightly before serving for the best texture.

Pro Tips for Making Overnight Breakfast Casserole

• Use Stale Bread: Slightly stale bread soaks up the egg mixture better without becoming mushy.
• Don’t Overfill: Give ingredients space to expand during baking to avoid a soggy or undercooked center.
• Cheese Last: Sprinkling cheese on top near the end of baking creates a delicious crust.
• Test for Doneness: Insert a knife into the center; it should come out clean when fully cooked.
• Prep in Advance: Assemble casseroles for holidays or busy weekends and refrigerate until ready to bake.

How to Serve Overnight Breakfast Casserole

Garnishes

Fresh herbs like parsley, chives, or cilantro brighten the dish and add a fresh aroma. A dollop of salsa, sour cream, or avocado slices also complement the hearty flavors wonderfully.

Side Dishes

Pair your casserole with light sides such as fresh fruit salad, yogurt parfaits, or a crisp green salad to balance the richness of the main dish.

Creative Ways to Present

Serve the casserole in individual ramekins for brunch guests or cut into squares to serve as easy grab-and-go portions for breakfast on busy days.

Make Ahead and Storage

Storing Leftovers

Store any leftover casserole in an airtight container in the refrigerator for up to 3 days to keep it fresh and tasty.

Freezing

Portion the casserole into freezer-safe containers or wrap individual servings tightly with foil and plastic wrap. Freeze for up to two months for convenient mornings ahead.

Reheating

Reheat refrigerated or thawed casserole pieces in the microwave or oven until warmed through. Adding a little cheese on top before reheating can restore the melty texture and flavor.
