So, I always thought I had the best breakfast casserole recipe (this overnight breakfast casserole that we make a few times a year).  I recently learned I was mistaken, because this breakfast casserole right here really is the BEST! And, although I still really love the other recipe, this one is more of a traditional breakfast casserole, with tons of eggs, and it’s fantastic!  Plus, you can still make it the night before so it’s perfect for holidays and special events where you don’t have a lot of time to prepare in the morning. I adapted this recipe from my sister Jessica over at Pretty Providence. I added a couple extra eggs, some milk, left out the mushrooms and cut the amount of bell peppers in half. The great thing about this recipe is how adaptable it is! It’s delicious with other types of cheese like pepperjack or Swiss, or you could try adding more veggies, like spinach or zucchini.

The main ingredients for this egg casserole are really simple and include: eggs, sausage, bell peppers, onion, and cheese. We add sour cream and milk to the egg mixture to make it creamy, light and fluffy.

To make the casserole combine the eggs, sour cream, milk, cheese, and salt and pepper in a large bowl. Next, cook the sausage, breaking it into small bits as it’s browning.  Set it aside and then saute the bell peppers and onions in the same pan. Add everything to the egg mixture and stir to combine.  Pour it into a 9×13” pan and bake for 35-50 minutes or until the edges are set and the center is a little jiggly in the center. It will continue to cook and set up as it cools.

After baking, leftover egg casserole can be stored in the fridge and enjoyed within 3-4 days. Leftovers are delicious reheated in the microwave. Yes, you can make this breakfast casserole a day ahead, or freeze it to bake another day! To make one day ahead of time, prepare everything as directed, up until baking. Cover the casserole and store it (unbaked) in the refrigerator overnight or up to one day. Bake in the morning, according to recipe instructions. To freeze breakfast casserole prepare the recipe and add to your pan. Cover well with plastic wrap and then tinfoil and freeze for 2-3 months. Allow it to thaw overnight in the refrigerator, and then let it come to room temperature before baking according to recipe instructions.
