What Is An Overnight Breakfast Casserole?

An overnight breakfast casserole marries the ingredients together as they soak and rest, resulting in a richer, deeper flavor. Typically, the ingredients are combined and refrigerated overnight, allowing the bread to absorb the creamy egg mixture. The next morning, simply bake and enjoy.

Ingredient Notes

  • Pork sausage: Pork sausage adds a savory touch, but turkey or vegetarian sausage can be used for a lighter option. If you have leftover sausage, consider using it in a Pork Stir Fry or a Biscuit with Sausage Gravy.
  • Egg: You can use a large or extra-large egg in this recipe. The egg acts as a binder for the casserole.
  • Milk: I use whole milk or 2% milk in this recipe, you can opt for non-dairy alternatives like almond or oat milk.
  • Salt and black pepper: Adjust the amount of salt and pepper to your liking.
  • Bread: Crusty varieties like French bread work best as they soak up the egg mixture without becoming too soggy. You can use day-old bread as well.
  • Cheese: You can use any type of cheese you like in this recipe. I like to use cheddar cheese for its flavor and meltability.

This is just an overview of the ingredients I used and why I used them. For the full recipe please scroll down to the recipe box at the bottom of the post.

Recipe Variations

Experiment and make this small breakfast casserole truly yours. Here are some ideas:

  • Spicy: Add red pepper flakes or diced jalapenos.
  • Vegetarian: Replace the pork sausage with a veggie alternative.
  • Deluxe: Add some sautéed mushrooms and spinach.
  • Cheese Burst: Use a mix of cheeses like mozzarella, cheddar, and pepper jack.

Expert Tips

  • This breakfast casserole has a savory flavor profile, reminiscent of a breakfast bread pudding. If your preference leans towards something sweeter, my small French Toast Casserole recipe would be an ideal choice.
  • For the best texture, ensure the bread in the casserole is thoroughly soaked, but avoid soaking it to the point where it becomes excessively wet.
  • Allow the prepared casserole to rest at room temperature for about 10 minutes before you bake it. This step helps in achieving an even cooking.

Frequently Asked Questions

What size baking dish is best to use?

The success of this recipe depends on the size of the baking dish you use. I use a 5-inch baking dish that measures 5-inches x 5-inches and is 1 ¾-inches deep. This dish has a base area of 25 square inches.

A 4×6-inch dish with an area of 24 square inches and a 6×6-inch dish with an area of 36 square inches will work as well. For best results, use a dish of similar size.

Can I add vegetables to a breakfast casserole?

Yes, a few tablespoons of chopped bell peppers, mushrooms, or spinach work great.

How long can I store the unbaked casserole in the fridge?

It’s best when baked within 12-18 hours of preparation but an uncooked egg casserole can stay in the refrigerator for up to 2 days.
