My Take On Hash Brown Casserole

Once you get a bite of this 5 ingredient hash brown casserole, you'll see why it's one of my favorite breakfast recipes! It's an easy-to-make meal that has a whole lot of flavor. 

My secret weapon to give this casserole the incredible flavor is Southwest potatoes. I use diced potatoes from Simply Potatoes, but regular hash browns will work great too! Those mixed with the savory breakfast sausage, eggs, and ooey-gooey cheese create what I think is one of the best breakfast casserole recipes ever.

I first made this hash brown casserole for breakfast over the holidays, and my family went crazy for it! Now it's a regularly requested dish at the Cunningham get-togethers, and I never mind since it's pretty simple to make. 

I guarantee the same will happen for your family, and I bet even your pickiest eater will look forward to this heavenly goodness!

How To Make 5 Ingredient Hash Brown Casserole

1. Prepare. Preheat the oven to 375°F and grease a 9x13-inch casserole dish with cooking oil or nonstick cooking spray.

2. Cook the sausage. Cook the breakfast sausage in a large skillet, breaking it apart until it's browned on all sides. Drain the excess grease from the skillet. 

3. Make the egg mixture. Whisk the eggs with salt, pepper, parsley, and milk in a large bowl. Add the hash browns or potatoes, cheddar cheese, and cooked sausage. Stir well to combine everything.

4. Bake the casserole. Transfer the casserole mixture to the prepared baking dish. Bake the casserole for 45 minutes or until the center is set. Serve the casserole warm, and enjoy!

My Tips To Make The Best Hash Brown Casserole

• I always use frozen hash browns or potatoes for convenience. However, if you want to make hash browns from scratch, you can do that too!
• Add some crushed potato chips or crunchy corn flakes to the top of the casserole to add an extra crunchy texture.
• Use any kind of shredded cheese you desire. Mozzarella and pepper jack are perfect substitutions for cheddar cheese.
• Insert a toothpick into the center of the baked casserole. If it comes out clean, the casserole is done.
• Serve the casserole with a dollop of sour cream on top for an added flavor.

How I Recommend Storing Hash Brown Casserole

In the fridge: Any leftover casserole can be stored in the fridge either transferred to an airtight container or in the casserole dish covered with plastic wrap. It will keep in the fridge for 3-5 days.

In the freezer: You can also store leftovers in the freezer for a longer shelf life. Wrap individual squares in plastic wrap and a layer of aluminum foil and keep them in a freezer-safe bag. The leftovers will last in the freezer for up to 3 months.

Reheating: My favorite way to reheat the leftover casserole is in the oven at 350°F for 15-20 minutes or more, depending on the portion size. Let the frozen casserole thaw overnight in the fridge and bake according to the recipe.

FAQs About This Hash Brown Casserole Recipe

How can I make my hash brown casserole crispy?

Once the casserole is baked through, cook it for an extra 3-5 minutes on broil in the oven. 

What can I serve hash brown casserole with?

Since this casserole recipe has the whole package, it's best to keep the side dishes to a minimum. But for larger parties, having the ultimate spread is perfect to keep every guest satisfied. Some of my go-to dishes to pair with this cheesy hashbrown casserole are these buttermilk biscuits, crepes, and fluffy pancakes.

Can I make this hash brown casserole ahead of time?

Yes, I've made it ahead of time a bunch! First, you'll want to thaw the frozen hash browns and drain the excess moisture. Then prepare the casserole up until baking. Cover the casserole dish with a lid and store it in the fridge overnight. Then just bake the casserole for a few extra minutes since it'll be chilled.  

Can I double this recipe?

Yes! If you're making this for a large crowd and want to make more, you can just double the ingredients and split the mixture into two casserole dishes. Either bake them side by side and add more baking time or use two separate casserole dishes.
