Overnight breakfast casserole is a life saver when it comes to busy mornings, especially around the holidays. That is because the casserole is prepared the night before and baked in the oven the next morning.
It is made by placing bread cubes and your favorite omelet vegetable ingredients in a casserole dish. Then a mixture of eggs, milk and spices are poured on top.
Add in a little cheese and let it sit in the refrigerator overnight. However, you can also bake it right away if you prefer.

The next morning, all you have to do is pull the casserole out of the refrigerator and let it warm up as the oven preheats. Then put it in the oven to bake until it is golden brown and set.
While the casserole bakes you can get ready for the day, enjoy a cup of coffee, or catch up on the news. Then when the timer goes off, you will be able to enjoy a delicious breakfast that is will keep you feeling full and satisfied.
Ingredients Required
There are many different types of breakfast casserole recipes. Depending on the occasion I will make French Toast Casserole, Cinnamon Roll Casserole, and even Biscuit Breakfast Casserole throughout the year.
However, for this recipe I am talking about a standard overnight breakfast casserole recipe that includes eggs, vegetables, bread cubes and cheese. Although there are many ways to cook the casserole, such as in a crock pot or even a pressure cooker, this recipe is designed to be put in the oven until firm and set.
Even though the recipe below includes specific ingredients, feel free to switch them up to customize the recipe to your taste preferences. There is no wrong way to make this dish, so feel free to experiment.
Bread:
You can use any kind of bread, but crusty or stale bread works best as it can hold up well to the egg mixture. If you don’t have stale bread, simply set the bread cubes out on the counter to dry out before making this recipe.
Eggs:
This is the main ingredient that binds everything together. You can use anywhere from 2-4 eggs in this recipe.
Milk or Cream:
This gives the casserole its iconic creamy texture. Feel free to use whole milk, 2%, or even plant based milk if you prefer.

Cheese:
Any kind of cheese can be used, but cheddar, mozzarella, and parmesan are popular choices. If you like spicy food, I highly recommend using Pepper Jack cheese to ramp up the flavor.
Meat:
Cooked bacon, ham, sausage or are all great options. Because the meat is previously cooked, it is a great time to use whatever leftover protein that you have in the refrigerator.
Vegetables:
You can add any vegetables you like to your overnight breakfast casserole, such as diced peppers, onions, spinach, zucchini or mushrooms.
Spices and Sauces:
Use any type of spices that you prefer. Some common choices, beyond what is listed in the recipe include thyme, oregano, garlic salt, and various types of hot sauces.
Equipment Required
Now that you know what ingredients you might use, it is time to gather the equipment that you need.
Baking dish: A baking dish is needed to assemble and bake the breakfast casserole. Because this is a small batch recipe, I use my 1 quart oval baking dish and it is the perfect size.
Mixing bowl: A mixing bowl is needed to mix the ingredients for the casserole before it goes in the baking dish.

Whisk: A whisk is used to beat the eggs and mix the wet ingredients together evenly.
Cutting board and knife: A cutting board and knife are needed to chop the bread, vegetables and meat that will go into the casserole.
Measuring cups and spoons: Measuring cups and spoons are needed to accurately measure the ingredients for the casserole.
Aluminum foil or plastic wrap: Aluminum foil or plastic wrap can be used to cover the casserole dish while it rests in the refrigerator.
How To Store & Reheat Overnight Breakfast Casserole Leftovers
Although this is a small batch recipe, you may have some leftovers depending on your portion size. This is often the case when this meal is served with other breakfast or brunch items.
To store leftover breakfast casserole, it is important to let it cool down to room temperature. Then, cover it tightly with plastic wrap or aluminum foil and refrigerate it. Leftover breakfast casserole can be stored in the refrigerator for up to 4 days.
To reheat the breakfast casserole, preheat the oven to 350°F (177°C). Remove the casserole from the refrigerator and let it come to room temperature while the oven heats up. Then, cover the casserole with aluminum foil and bake it in the preheated oven for 15-20 minutes, or until it is heated through.
Alternatively, you can reheat individual portions of the casserole in the microwave. Place a serving on a microwave-safe plate and microwave on high for 1-2 minutes, or until it is heated through.
It is important to note that reheated breakfast casserole may not have the same texture as the freshly baked casserole. However it is still just as delicious, if not even more flavorful on day 2.
