Hash Browns, Sausage and Eggs—All in One Big Cheesy Casserole!

Whether you’re cooking up breakfast for a crowd, or craving an easy breakfast-for-dinner situation (which is always a win in our homes), this easy, cheesy sausage breakfast casserole recipe will fit the bill. The secret to its deliciousness? Well, actually, it’s not really a “secret” that frozen hash browns rock, but using them as the base of this casserole is definitely a key to its success. To make this casserole over-the-top good, those delicious frozen hash browns partner up with a whole mess of other breakfast favorites, like:

  • Lots of cheddar cheese
  • Heavy cream
  • Breakfast sausage! You can use links or ground—if you like a hint of sweetness, look for one that has a bit of maple in it.
  • Eggs (of course).
  • Butter (also of course)
  • A pinch of cayenne (here at TMP, cayenne is also an “of course”)

How To Make Sausage Breakfast Casserole

Sometimes you have to cook them before you’ve even had coffee, so breakfast recipes must must must be easy, right? Well, this one is about as easy as they come—and gloriously cheesy, too! Here’s How to make this hash brown-and-sausage casserole:

  1. Brown the sausage.
  2. Give the eggs and cream a really thorough whisking, so you’re sure to create a lovely, silky custardy mixture to hold your casserole together.
  3. Stir in the sausage, cheese and scallions.
  4. Dump the whole breakfast-y mess into a greased 9x13 pan.
  5. Bake! Bake this breakfast casserole uncovered at 350°F for 40 minutes, then cover it and bake it for another 15 minutes. Covering it at the end ensures that the cheese on top is melty and gooey, but not overly brown.

The Most Important Brunch Recipe Question of All: Can I Make This Breakfast Casserole Ahead of Time?

And the most important breakfast recipe answer of all time—yes! This breakfast casserole is great for making ahead of time. You even have a couple of options, depending on how fast you want things to move in the morning. You can either:

  • Option 1: assemble it to the point of baking the night before, and then do all of the baking the next morning (which takes about an hour, total) OR
  • Option 2: do the first 40 minute bake the night before, and then all that’s left the next morning is to do the last 15-minute bake.

Either way, it makes a great, easy make-ahead breakfast. Plus, with eggs, sausage and hash browns in the casserole, you don’t need to serve it with many sides—just some simple sliced fruit alongside this casserole is enough to turn it into a full on brunchy feast.

Can You Freeze Breakfast Casserole?

Yep! Although in our homes it usually disappears before we have a chance to freeze any leftovers! But, if you’re lucky enough to have a lot of leftovers, go for it! For freezing, we like to slice it up for easier storage, and then wrap the slices tightly in cling wrap. The breakfast casserole should be good in the freezer for about three months.

Sausage Breakfast Casserole

  • Serves: 12
  • Prep Time: 15 min
  • Cook Time: 55 min
  • Calories: 490

Ingredients

  • 1 lb Breakfast sausage, raw ground (buy the maple kind if you want a hint of sweetness)
  • 12 Eggs
  • 1 tsp Salt
  • ½ tsp Pepper
  • ½ tsp Cayenne
  • 1 cup Whipping cream
  • 16 oz Cheddar cheese, shredded, divided
  • 1 bunch Green onions, optional (about ½ cup)
  • 1 lb Hash browns, thawed
  • 2 tbsp Butter, melted

Method

  1. Heat oven to 350°F.
  2. Heat a large skillet over medium heat. Brown the sausage (If you buy sausage links, make sure to remove the casting first.)
  3. In a large bowl, whisk the eggs with the salt, pepper, cayenne and whipping cream until fully combined and all of the yolks are broken and incorporated.
  4. Add the browned crumbled sausage, ¾ of the cheese, green onions and hash browns to the bowl with the egg mixture. Stir until fully combined.
  5. Spread the butter into a 9x13 baking dish. Pour the egg and sausage mixture into the baking dish and top with remaining cheese.
  6. Bake for 40 minutes before covering with foil. Bake for another 15 minutes with foil on so the top doesn't get too brown.
