Sausage and Egg Casserole FAQs

Can I freeze breakfast casserole?

Yes, breakfast casserole freezes very nicely as long as you follow the following steps. First, be sure to use a quality disposable pan so your dish isn’t stuck in the freezer. Prepare the egg bake recipe as instructed and let it cool for about 30 minutes. Cover with plastic wrap and push it down onto the surface of the casserole to keep frost from forming on it. Next, use foil to cover the whole pan before freezing it for up to 3 months. To serve, let the egg bake thaw in the fridge for a few days, then reheat individual pieces in the microwave.

How long does sausage egg casserole last in the fridge?

Sausage and egg casserole will last up to one week in your fridge in an airtight container. For food safety reasons, be sure the cooked egg bake recipe is still hot when it is packed up and put in the refrigerator. Most wrongly believe you should wait until the food has cooled to room temperature before it goes into the fridge. However, the fridge is the safest place to cool your food quickly to keep bacteria from growing.

Egg Bake Recipe Variations

Being a home cook provides endless opportunities to experiment with recipes, personalizing them to your tastes and creativity. Any of the following variations would be great spin-offs of this sausage and egg casserole recipe.

Use different proteins for a variety of flavors. Cooked bacon or chopped pieces of ham would be delicious in this egg bake recipe. You can either add them to the sausage if you are a meat lover or substitute them for the sausage.
Add more vegetables if you love them. Use fresh vegetables and saute them for a few minutes before adding them to the casserole. You want to remove a bit of their natural moisture and get them on their way to being cooked. Mushrooms, spinach, jalapenos, and bell peppers would be amazing.
Try different types of cheese that have a bit more personality than the standard cheddar cheese. Pepper jack, sharp cheddar, Swiss, and feta would all provide a distinctive flavor to the sausage and egg casserole.
Add spice in a variety of ways, depending on what you like. You can add some fresh jalapeno peppers, red pepper flakes, or sriracha sauce to the egg bake recipe.

Recipe FAQs

Can I make sausage and egg casserole ahead of time?

Yes, you can easily make this egg bake recipe ahead of time and you have two different options to do so. You can assemble the whole dish, cover it, and refrigerate it overnight before baking it the next morning. This is my preferred method. Otherwise, you can completely bake the sausage and egg casserole, cover it, and keep it in the refrigerator until you are ready to serve it. I would cut individual pieces and heat them in the microwave to reheat them. If you put it in the oven, you’ll dry it out by the time it gets warm all the way through.

How do I know when the egg bake recipe is cooked?

Do not overbake this recipe or it gets all dried out and the eggs get a mealy texture. You want to bake it just long enough that when you gently shake the pan, the eggs are set in the center of the casserole. Because every oven is slightly different, start checking your sausage and egg casserole about 5 minutes early.

Can I use frozen hash brown potatoes?

Yes, the recipe uses shredded hash brown potatoes directly from the freezer. I would never remember to take them out to thaw in time so I wrote it specifically so you could use frozen ones. If you use thawed potatoes, just check the time about 10 minutes earlier since the sausage and egg casserole will bake faster with thawed potatoes.
