A beloved Utah comfort dish, this creamy hash brown casserole is layered with sharp cheddar, sour cream, and a buttery cornflake topping. It earned its name for being the crowd-pleasing potato bake traditionally brought to neighborhood gatherings after a loss, though it now shows up at every kind of potluck across the Mountain West.

Ingredients
For the potato base
- 1 (32 oz) bag frozen shredded hash browns, thawed
- 1 cup sour cream
- 1 can (10.5 oz) condensed cream of chicken soup
- 1/2 cup melted unsalted butter
- 1 small yellow onion, finely diced
- 2 cups sharp cheddar cheese, freshly shredded
- 1 teaspoon garlic powder
- 1/2 teaspoon kosher salt
- 1/2 teaspoon black pepper
For the cornflake topping
- 3 cups cornflakes cereal, lightly crushed
- 1/4 cup unsalted butter, melted
- 1/2 teaspoon smoked paprika
Directions
- Preheat the oven to 350°F (175°C) and lightly grease a 9×13-inch baking dish with butter or nonstick spray.
- In a large mixing bowl, whisk together the sour cream, condensed cream of chicken soup, melted butter, diced onion, garlic powder, salt, and pepper until smooth and well combined.
- Fold the thawed hash browns and shredded cheddar cheese into the sour cream mixture, stirring gently until every strand is evenly coated.
- Pour the potato mixture into the prepared baking dish and spread it into an even layer with a spatula.
- In a medium bowl, toss the crushed cornflakes with the melted butter and smoked paprika until the flakes are glistening and evenly coated.
- Scatter the buttered cornflake topping uniformly over the potato base, pressing down just slightly so the flakes adhere during baking.
- Bake uncovered on the middle rack for 40 to 45 minutes, until the casserole is bubbling at the edges and the cornflake topping is deep golden brown.
- Remove from the oven and let the casserole rest for 8 to 10 minutes so the creamy base sets up before scooping and serving hot.
Cook’s Notes
- Always shred your own cheddar cheese from a block; pre-shredded cheese contains anti-caking agents that prevent smooth melting.
- For a tangier profile, swap half the sour cream for full-fat plain Greek yogurt.
- Crushed Ritz crackers or potato chips make excellent substitutions for the cornflake topping if you prefer a different crunch.
- Do not skip the resting time after baking, or the casserole will run when sliced; the eggs and starch need a few minutes to set.
- To make ahead, assemble the potato base a day in advance, refrigerate, and add the cornflake topping just before baking.
