Cheesy Hash Brown Casserole With Corn Flakes Topping Recipe

Make Cheesy Hash Brown Casserole With Corn Flakes Topping Recipe for a crispy, creamy crowd-pleaser.

Ingredients

• 6 cups frozen shredded hash browns, thawed
• 1 cup chopped onion
• 2 cups sour cream
• 2 cans (10.75 oz each) condensed cream of chicken soup
• 2 cups shredded sharp cheddar cheese
• 1/2 cup melted butter
• 1 tsp salt
• 1/2 tsp pepper
• 2 cups crushed corn flakes
• 1/4 cup melted butter

Instructions

Step 1: Preheat the oven

Preheat the oven to 350°F (175°C) so it's ready when the casserole is assembled. This small step sets the stage — while the oven warms, you'll move quickly through the mixing and assembly so the shredded potatoes don't sit too long. Keep your baking dish close by and lightly greased so it's ready for the mixture.

Step 2: Combine the shredded potatoes and aromatics

In a large mixing bowl, toss the thawed shredded hash browns with the chopped onion so the onion pieces distribute evenly through the potato shreds. Add the sour cream and both cans of condensed cream of chicken soup to create a creamy binding base. Stir in the shredded sharp cheddar, melted butter, salt, and pepper until the mixture is homogenous — you should see pockets of cheddar and moist, slightly glossy potato strands clinging together.

Step 3: Transfer into the baking dish

Spoon the combined cheesy hash brown mixture into the greased 9x13 inch rectangular baking dish, evening the surface with a spatula so the layer is compact but not overly compressed. Smooth the top gently so the final topping will sit uniformly and the casserole will bake consistently from edge to center.

Step 4: Prepare the crunchy corn flakes topping

In a small bowl, combine the crushed corn flakes with 1/4 cup melted butter, stirring until the crumbs are evenly coated and look shiny and slightly clumped. The butter should just moisten the flakes so they will brown crisply in the oven without going soggy.

Step 5: Finish assembly and get ready to bake

Sprinkle the buttery crushed corn flakes evenly over the smoothed casserole surface so the golden crumbs form a uniform layer across the rectangle. Give the dish a gentle shake or tap on the counter to settle the topping into any crevices. This fully assembled, unbaked casserole — creamy interior, crumbly buttery top — is ready to go into the oven.

Step 6: Bake until bubbly and golden

Place the uncovered casserole on a rack and bake for about 45 minutes, watching for the corn flakes to turn a deep golden brown and the filling to bubble at the edges. The top should be crisp and fragrant while the interior becomes tender and fully cooked; remove when the center is set and the surface is evenly toasted.

Step 7: Rest and serve warm

Remove the casserole from the oven and let it cool slightly on the counter so the filling firms up a touch and is easier to scoop. Serve warm straight from the rectangular dish so each portion shows the creamy, cheesy interior studded with tender hash brown shreds and the crisp, toasted corn flakes crust.

Notes

• Thaw and pat dry hash browns to prevent a watery casserole.
• Squeeze excess moisture from fresh-grated potatoes before using.
• Tent with foil if the topping browns too quickly while the center finishes baking.
• Freeze portions wrapped tightly for up to 3 months for easy meals.
