How to Make Cheesy Hashbrown Casserole

Not only is this recipe super easy to make, but it’s also easy to make ahead when you use prepared potatoes. It only takes a few minutes to mix together!

COOK ONIONS Start by preheating the oven to 350 degrees F. In a large pot over medium heat, melt butter, then add green onions, and sauté for about 3 minutes, until onions are tender and fragrant.

MAKE SAUCE To the pot, add the shredded cheddar cheese, sour cream, and cream of chicken soup. Stir to combine and cook for a few minutes until melted and bubbly.

PRO TIP: Make sure to use freshly grated cheese, not pre-shredded! Pre-shredded cheese has additives in it to prevent clumping, but those additives can also make the sauce grainy in texture once melted.

How to Make Ahead

This recipe is SO easy to make ahead and bake later!

To Refrigerate: Make the recipe as directed, then cover and refrigerate for up to 5 days before baking.

To Freeze: Make the recipe as directed, do not add the cornflakes. Freeze covered in a freezer-safe baking pan for up to 3 months. Refrigerate overnight to thaw.

Before baking, add the topping and increase the baking time if needed till the center is hot and bubbly.

What Kind Of Potatoes To Use?

This recipe uses frozen shredded potatoes or hashbrowns, but you could also use freshly grated potatoes, cubed potatoes fresh or frozen, or thinly sliced potatoes.

Keep in mind that if you use fresh potatoes, you’ll need to decrease the baking time in order to prevent mushy potatoes.

Tips and Variations

Add 2 cloves of minced garlic to the onion when sauteing in butter for a little extra flavor!
If you don’t like green onions, leave them out.
Add pre-cooked diced ham for more flavor and protein!
Change up the cream of chicken soup! You could use cream of mushroom, cream of celery, or canned cheddar soup for extra cheesy goodness.
