How to Make Overnight Breakfast Casserole (Overview)

Let’s recap how to bring this beautiful dish to life:

First, cook the sausage until it’s perfectly browned. While it’s cooking, whisk together those eggs and milk. Layer the cubed bread in a baking dish, toss on the sausage, and pour that creamy egg mixture over everything! Don’t forget the cheese on top! Pop it in the fridge overnight, and come morning, just bake it while you sip your coffee. Easy peasy!

Pro Tip: Let it rest for a few minutes after baking so it holds together perfectly when you slice into it.

How to Serve Overnight Breakfast Casserole

Serving this casserole is a delight! Cut it into large squares and serve it warm, possibly with some fresh fruit on the side for a pop of color. Drizzle with a bit of hot sauce if you like a kick. The warm, cheesy layers will make your kitchen smell amazing, and the golden brown top will have everyone coming back for seconds. Colorful, crunchy sides like crispy hash browns would be a fantastic pairing too!

Tips to Make Overnight Breakfast Casserole

Want to up your casserole game? Here are a few tricks:

1. Use Day-Old Bread: It soaks up that egg mixture better and reduces waste. Win-win!
2. Add Extras: Toss in chopped bell peppers or onions for added flavor and texture.
3. Make It Your Own: Swap out the sausage for bacon or switch cheeses for a twist.
4. Use A Baking Dish with a Lid: This helps retain moisture while it chills overnight.

Variation

Feeling adventurous? Try going meatless by swapping the sausage for sautéed mushrooms or chopped spinach. For a spicy kick, add diced jalapeños or your favorite spices to the egg mixture. Want a lighter option? Use whole grain bread and skim milk—your tastebuds won’t complain!
