What Is Hash Brown Potato Casserole?
Hash Brown Potato Casserole belongs to a beloved category of American potluck cooking: the creamy, cheesy potato bake built on a handful of pantry and freezer staples. Shredded frozen hash browns stand in for fresh potatoes, saving all the peeling and grating, while a mixture of cream soup, sour cream, and cheddar binds everything into a rich, cohesive casserole.
This particular version, sometimes called “funeral potatoes” in other parts of the country because of its long history at potlucks and gatherings of all kinds, has been a fixture on Midwestern tables for decades. Its staying power comes from exactly what makes it so appealing here: minimal ingredients, almost no technique required, and a result that feels like real comfort food every time.

Ingredients You’ll Need
The short ingredient list means every item matters.
Frozen Shredded Hash Brown Potatoes
You need 1 bag (30 ounces) of frozen shredded hash brown potatoes, thawed. Using frozen, pre-shredded potatoes saves significant time and effort compared to grating fresh potatoes, while still delivering that classic hash brown texture. Thawing them fully before use is essential, since frozen potatoes hold a surprising amount of water that needs to be removed for the casserole to bake up properly.
Cream of Chicken Soup
You need 1 can (10.5 ounces) of cream of chicken soup. This casserole classic acts as the creamy binder that holds everything together and infuses the whole dish with a savory, comforting flavor.
Sour Cream
You need 1 cup of sour cream. Sour cream adds tang and extra creaminess, rounding out the richness of the soup and giving the casserole its characteristic smooth texture.
Shredded Cheddar Cheese
You need 2 cups of shredded cheddar cheese. Cheddar melts throughout the casserole, adding sharp, savory flavor and helping bind the potatoes together as everything bakes.
Equipment
- A 9×13-inch baking dish
- A large mixing bowl
- A clean kitchen towel, for wringing out the hash browns
- Aluminum foil
- A large spoon, for stirring and serving
How to Make Hash Brown Potato Casserole, Step by Step
Step 1: Preheat the Oven and Prepare the Dish
Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish, so the casserole releases easily once baked.
Step 2: Squeeze the Excess Water from the Hash Browns
Make sure the hash browns are fully thawed, then place them in a clean kitchen towel and squeeze out as much excess water as you can. This step is genuinely the most important trick in the whole recipe. Frozen shredded potatoes hold a surprising amount of moisture, and skipping this step is the most common reason a hash brown casserole turns out watery or loose instead of firm and cohesive.
Step 3: Combine the Ingredients
In a large mixing bowl, stir together the well-drained hash browns, cream of chicken soup, sour cream, and shredded cheddar cheese until everything is evenly combined.
Step 4: Transfer to the Baking Dish
Spread the mixture evenly into the prepared baking dish, smoothing the top so it bakes consistently from edge to center. Cover the dish tightly with foil.
Step 5: Bake Covered, Then Uncovered
Bake covered for 45 minutes. Then remove the foil and continue baking for 20 to 25 minutes longer, until the top is golden brown around the edges and the casserole is hot all the way through. The initial covered bake allows the potatoes to cook through gently, while the uncovered stage lets the top brown and the edges crisp slightly.
Step 6: Rest Before Serving
Let the casserole sit for 10 minutes before cutting and serving. This rest allows it to set up nicely, so it holds together in clean portions rather than spreading out on the plate.

Tips for the Best Hash Brown Casserole
Squeeze Out the Water Thoroughly
This cannot be overstated. A good, firm squeeze in a clean kitchen towel removes the excess moisture that would otherwise turn the casserole loose and watery on the bottom. Take the time to do this well.
Make Sure the Hash Browns Are Fully Thawed
Partially frozen hash browns are harder to wring out properly and can throw off the baking time. Give them enough time in the refrigerator or at room temperature to thaw completely first.
Stir Until Evenly Combined
A thorough mix ensures the soup, sour cream, and cheese coat every strand of potato, so the flavor and texture are consistent throughout.
Don’t Skip the Covered Bake
Baking covered for the first 45 minutes allows the potatoes to cook through gently without the top over-browning before the inside is fully hot.
Let It Rest Before Cutting
Ten minutes of resting time makes a real difference in how neatly the casserole cuts into squares.
Save Back Some Cheese for the Top
Reserving about half a cup of cheddar to sprinkle on right when you uncover the dish gives the top an even deeper, more golden finish for the final bake.
Troubleshooting Common Problems
My Casserole Turned Out Watery
This almost always comes down to insufficient draining of the hash browns. Next time, thaw them completely and wring out as much water as possible in a clean towel before mixing.
My Casserole Didn’t Brown on Top
Save back a little extra cheddar to sprinkle on when you remove the foil, and make sure you’re baking uncovered for the full 20 to 25 minutes at the end.
My Casserole Is Dry
This can happen if it baked a bit too long uncovered. Check for doneness at the 20-minute mark during the uncovered stage next time.
My Casserole Tastes Bland
Taste the mixture before baking and consider adding a pinch of salt, pepper, or garlic powder, since cream of chicken soup varies in seasoning between brands.
The Edges Browned Too Quickly
If the edges are browning faster than the center is heating through, loosely tent the dish with foil for part of the uncovered baking time.
Variations to Try
Extra Cheesy Top
Save back about ½ cup of the cheddar and sprinkle it over the casserole when you uncover it for the final bake. This gives the top a deeper, more pronounced golden, cheesy crust.
Soup Swap
Cream of mushroom can stand in for cream of chicken if that’s what you keep in the pantry. It gives the dish a slightly deeper, earthier flavor while keeping the same creamy texture.
Add a Crunchy Topping
Sprinkle crushed cornflakes or buttery cracker crumbs over the top before the final uncovered bake for extra crunch against the creamy interior.
Add Onion
Stir in finely chopped onion or a few tablespoons of dried minced onion for extra savory depth.
Bacon Addition
Fold in crumbled cooked bacon for a smoky, salty twist that pairs beautifully with the cheddar.
Different Cheese
Swap the cheddar for a Colby Jack or Monterey Jack blend for a slightly different, milder flavor.

Make-Ahead, Storage, and Freezing
Make ahead: Stir the casserole together and spread it in the baking dish up to a day ahead. Cover and refrigerate it, then bake it the next day. If it’s going into the oven cold from the refrigerator, add a few extra minutes to the covered baking time.

Freezing: This casserole can be frozen either before or after baking. To freeze unbaked, assemble it in a freezer-safe dish, wrap tightly, and freeze for up to 3 months; thaw overnight in the refrigerator before baking as directed. Baked leftovers can also be frozen in individual portions for up to 3 months.
Reheating: Warm individual portions in the microwave, or reheat the whole dish covered with foil in a 350°F oven until heated through.
Frequently Asked Questions
Do I really need to squeeze the water out of the hash browns?
Yes, this is the single most important step in the recipe. Frozen shredded potatoes hold a lot of moisture, and skipping this step is the most common reason the casserole turns out watery instead of firm.
Can I use fresh potatoes instead of frozen hash browns?
Yes, though you’ll need to shred and partially cook them first, then drain and squeeze out excess moisture the same way you would with the frozen variety.
Can I substitute a different cream soup?
Yes. Cream of mushroom works well in place of cream of chicken and gives the dish a slightly deeper, earthier flavor.
Can I make this casserole ahead of time?
Yes. Assemble it up to a day in advance, cover, and refrigerate. Add a few extra minutes to the covered baking time if it goes into the oven cold.
Can I freeze this casserole?
Yes, both before and after baking. See the storage section above for details on freezing at each stage.
How do I get the top extra golden and cheesy?
Reserve about half a cup of the cheddar and sprinkle it over the casserole when you remove the foil for the final uncovered bake.
Can I double the recipe?
Yes, though you’ll need a larger baking dish, and the baking time may need slight adjustment to fully heat the center.
