Egg Casserole

I am always looking for new ways to serve up some of our favorite breakfast foods. Bonus if you can fit all of those favorites into one easy to prepare dish. Eggs, cheese, potatoes and sausage stuffed into this simple egg casserole make this my new favorite breakfast!

I am not one to jump out of bed in the morning, ready to cook a huge meal. I am more the stumble out of bed, get me my coffee, then you can talk to me kind of person. It’s my routine and I like it! It also means that I’m not going to be slaving over the stove for an hour making the perfect breakfast.

So when I can spend a few minutes putting together a quick egg casserole that’s already got our favorite breakfast foods in it, that’s a major win in my book.

An Easy Make Ahead Egg Casserole

Prepare your sausage egg casserole the night before and pop it into the oven to bake in the morning. Meanwhile you can chop up some fresh fruit for a quick Fruit Salad and breakfast is done! Or make it part of a fancy holiday spread with Cheese Danish, Buttermilk Waffles or Biscuits with Homemade Apple Butter.

How to Make an Egg Casserole with Hash Browns

This Egg Casserole take about 15 minutes to prep and 45 minutes to bake. It’s pretty much hands off, which I love, plus you can customize with your favorite cheeses and proteins.

  1. PREP: Cook some chopped onions with half a pound of ground breakfast sausage. You can use regular sausage or spicy depending on your tastes. Break up the sausage into small pieces of it cooks. Links would work fine, just chop them up when they’re finished cooking. Drain cooked sausage on paper towels to remove any excess grease.
  2. LAYER: Spray a medium sized baking dish (I use 11×7-inch) with nonstick cooking spray and press frozen shredded hash browns into the bottom of the dish. Top with sausage and onions and sprinkle on some shredded cheese. I like to use a mix of cheddar and jack cheese, but you could use your favorite. Whisk eggs with milk, salt and pepper and pour over the top.
  3. BAKE: Preheat your oven to 350 degrees and bake the egg casserole uncovered for 40-45 minutes. Let stand for several minutes to cool and set completely. The egg casserole is completely cooked when the eggs are set in the middle (not jiggly) and the temperature on an instant read digital thermometer reads 160 degrees F.

Make Ahead Notes

To make this egg casserole ahead of time, follow the instructions up to just before baking. Cover tightly with plastic wrap and pop in the fridge overnight or up to 24 hours. Bake as directed, adding 5 minutes to the cook time.

Serving Suggestions

Egg Casserole might be considered a breakfast food but it can really be served for any meal. It’s an excellent source of protein. We enjoyed this dish for our Christmas morning breakfast, with a side of fresh homemade biscuits and strawberries.

Try it for dinner tonight! Roast some asparagus or saute green beans to serve on the side.

We love topping our eggs with salsa and sour cream, some sliced green onions or minced parsley.

Can you freeze an egg casserole?

Freezing a fully cooked egg casserole is simple. Let cool, then cover with plastic wrap. Place the whole pan in a large freezer bag or wrap completely with foil. Pop it in the freezer for up to 3 months. To reheat, thaw completely in the fridge and bake at 350 for about 20 minutes or until warmed through.

Store leftovers tightly covered in the fridge for up to 3-4 days. Reheat large portions in the oven or individual portions in the microwave.
