Hash Brown Casserole Ingredients Notes

These are the ingredients you’ll need to make this old-fashioned hash brown casserole recipe: 

• Frozen hash browns: This easy recipe starts with a package of (thawed) frozen hash brown potatoes. 

• Canned soup: A can of condensed cream of chicken soup adds creaminess and flavor. 

• Cheddar: Use pre-shredded Cheddar cheese or shred your own cheese from the block. 

• Sour cream: An 8-ounce container of sour cream adds richness and tangy flavor. 

• Butter: Mix a stick of melted butter into the casserole and drizzle the casserole with another stick of melted butter. 

• Onion: You’ll need ½ cup of chopped onion. 

• Seasonings: Season the hash brown casserole with salt and ground black pepper. 

• Cornflakes: A cup of crushed cornflakes is the perfect crunchy topping. 

How To Make It Step-By-Step Directions

Step 1: Gather all ingredients. Preheat the oven to 350 degrees F (175 degrees C).

Step 2: In a large bowl, mix the hash browns, cheddar cheese, cream of chicken soup, sour cream, half of the melted butter, onion, salt, and pepper. Spread the mixture into a 9×13-inch baking dish. 

Step 3: Sprinkle the crushed cornflakes evenly over the top. Drizzle with the remaining melted butter. 

Step 4: Bake for 1 to 1½ hours, or until the casserole is hot and bubbly and the top is golden brown. 

Step 5: Serve and enjoy!

Cook’s Note

Use cream of mushroom or cream of celery soup for a vegetarian version.

Replace the cornflakes with crushed Ritz crackers or potato chips for a different crunchy topping.

Garnish with sliced green onions before serving for extra color and flavor.

Storage
