It’s been a crazy week, the weekend is coming, and entire family is craving a hearty breakfast—enter this Easy Hashbrown Breakfast Casserole.

You spend 10 minutes putting it together, then put it in the oven and get back to your cup of coffee.

You can even prep it up to 2 days ahead of time to make your morning easier!

One of the things I love about this recipe is that it freezes really well, either before or after being baked, which means it’s a great holiday breakfast for Christmas morning or Easter brunch (but it’s a huge hit with my family any time of year!).

This hashbrown and sausage breakfast casserole is filling on its own, but I often serve it with some toast and crispy bacon.

If you love this dish, you’ll love my cheesy Hashbrown Casserole that has crispy cornflakes on top. These Breakfast Potatoes are also a great option to add to your breakfast spread!

Ingredients Needed:

  • Sausage: any kind of breakfast sausage will work for this recipe. I tend to use either pork or turkey, with the casings removed.
  • Hash Browns: use cubed or frozen shredded hash browns. You can use homemade hashbrowns too, as long as they are cooked through before adding to the recipe.
  • Bell Pepper: I like to use red and green bell peppers in this recipe, but you can use your favorite colors.
  • Onion: adds a great savory flavor to the dish, and a bit of sweetness as it caramelizes slightly in the pan.
  • Eggs: the base of the mixture that binds the ingredients together.
  • Milk: use whole or evaporated milk, or even use part milk, part cream for a richer flavor.
  • Seasonings: kosher salt, dried parsley, and ground black pepper will enhance the flavors of the sausage and veggies to make a delicious dish!
  • Cheese: I tend to use a mix of sharp cheddar and mozzarella cheese, but you can use your favorite. Buy a block of cheese that you shred yourself for the best flavor.

Hashbrown Breakfast Casserole FAQs

Do I have to thaw frozen hash browns for casserole?

Nope! You can bake them until crispy before adding them if you prefer, but it’s not needed for this recipe.

How do I store hash brown breakfast casserole?

Store this recipe in an airtight container in the refrigerator for 2-3 days. Allow it to cool to room temperature before putting it in the fridge.

Can I freeze breakfast casserole?

Absolutely! Cool to room temperature then cover with plastic wrap and/or foil and freeze for up to 3 months.
You can do this after baking it as directed – just let it cool to room temperature first.
You can even freeze it before baking it! To serve, thaw in the refrigerator overnight and reheat/heat in the oven until piping hot.

Tips and Notes

  • Freezing and baking. If you plan to make this recipe ahead of time enough to freeze it, make sure you assemble it in an oven safe dish so can defrost it and put it straight in the oven without having to re-dish it.
  • Reducing the recipe. If you prefer to make a smaller recipe, you can halve the ingredients and bake it in an 8×8″ or 9×9″ pan. You can also divide the recipe between two smaller pans and freeze one for later.
  • Homemade Hashbrowns. Here’s how to make Crispy Shredded Hashbrowns that you can use in this recipe!

Hashbrown Breakfast Casserole Variations

  • Meat. Use any kind of breakfast sausage, Italian sausage, cooked ham, cooked bacon, or even go meatless. Just be sure any meat added is cooked before assembling the casserole.
  • Vegetables. You can use any vegetables you want, just be sure to cook them or at least soften them first. The exception is spinach, which you can just chop and toss in.
  • Milk. I prefer to use evaporated milk in this recipe, but any will work, even cream. Higher fat means a richer, creamier casserole, so keep that in mind.
  • Cheese. Use any of your favorite cheeses for this recipe. Monterey Jack, Pepper Jack, mozzarella, cheddar, or a Mexican cheese mix are good options.
  • Spice it up. Add some spices like cayenne pepper, red pepper flakes, or even chopped jalapenos to the mixture before baking it for a little bit of a spicy kick.
  • Garnish. Add finely chopped green onions or chopped fresh herbs on top of the casserole for more flavor.

Serve this sausage hashbrown breakfast casserole on its own for breakfast, or with a side of scrambled eggs, crispy Air Fryer Bacon, or even these Breakfast Stuffed Peppers.

These Breakfast Foil Packets are an easy way to make a full-cooked breakfast for a crowd as well (also handy for when you’re camping!) and this Easy Loaded Baked Potato Quiche is a filling dish as well.

This guide of how to make a Cold Brew Coffee, my Blueberry Smoothie, and this Healthy Strawberry Smoothie are great for breakfasts too!
