A Top 10 Breakfast FAvorite!

If we’ve said it once, we’ve said it a million times, we LOVE breakfast – especially savory dishes like our favorite hashbrown breakfast casserole!

This casserole is one of our top 10 breakfast recipes! It has bacon, potatoes, and THREE kinds of cheese. It’s a favorite because it not only tastes amazing, but it feeds a crowd, is ultra simple to throw together, and uses simple ingredients.

We also love it for holidays because it can be prepped the night before for an even easier morning (although it only takes 15 minutes of work). For more make ahead breakfast casseroles, try our: Sausage Breakfast Casserole and Potato Egg Casserole.

WHY WE LOVE IT:

  • 15 minutes of prep. Just mix and bake – it’s on the table in under an hour!
  • Overnight casserole. Make this the night before or freeze it for a last-minute breakfast – or dinner!
  • We love hashbrowns. Who doesn’t love potatoes and cheese? Add eggs and Bacon crumbles and you have one filling, savory breakfast!

How to Make Hashbrown Breakfast Casserole

  1. PREP. Preheat oven to 350°F, and grease a 9×13-inch baking dish.
  2. BACON. Cook 1 pound diced bacon in a large skillet until browned and put into a large bowl.
  3. ASSEMBLE. Stir in 4 cups frozen shredded hashbrown potatoes, 9 lightly beaten eggs, 2 cups cheddar cheese, 1½ cups cottage cheese, 1¼ cups shredded Swiss cheese, and salt & pepper to taste. Pour the potato and egg mixture into a greased casserole dish.
  4. BAKE. Bake for 40-45 minutes. If the top is browning more quickly than the middle is baking, tent a piece of aluminum foil over the top to keep it from getting too crispy and dry.
    • Let stand for 10 minutes before serving. ENJOY!

Store leftovers in individual serving containers in the fridge for 3-4 days or in the freezer for 2-3 months.

    Is there anything I could sub for the Cottage cheese? I think this would be awesome as part of Christmas morning breakfast but my husband won’t touch it with cottage cheese.

    1. Kristyn Merkley says:

      You could do sour cream or yogurt? I haven’t tried, but usually those are great substitutes for cottage cheese.

      1. Rhena Kinslow says:

        does the cottage cheese not melt in, or can you tell its cottage cheese.? my boyfriend had the same problem with the texture of cottage cheese 🙁

      2. Kristyn Merkley says:

        It doesn’t totally melt, but you can use yogurt, sour cream, mayo, or ricotta cheese if you prefer.
