Cheesy Potato Cornflake Crust (Printer-Friendly)

A comforting casserole with shredded potatoes, sharp cheddar, and a crunchy cornflake cheddar topping.

# What You'll Need:

→ Potatoes

01 - 32 oz frozen shredded hash brown potatoes, thawed

→ Sauce

02 - 10.5 oz can condensed cream of chicken soup
03 - 1 cup sour cream
04 - 1/2 cup unsalted butter, melted
05 - 1/2 teaspoon garlic powder
06 - 1/2 teaspoon onion powder
07 - 1/2 teaspoon kosher salt
08 - 1/4 teaspoon black pepper

→ Cheese

09 - 2 cups sharp cheddar cheese, grated

→ Topping

10 - 3 cups cornflakes, lightly crushed
11 - 1/4 cup unsalted butter, melted
12 - 1 cup sharp cheddar cheese, grated

# How To Make It:

01 - Preheat oven to 350°F. Grease a 9x13-inch baking dish with cooking spray or butter.
02 - In a large mixing bowl, combine thawed hash browns, cream of chicken soup, sour cream, 1/2 cup melted butter, garlic powder, onion powder, salt, black pepper, and 2 cups grated cheddar cheese. Stir until fully combined.
03 - Spread the potato mixture evenly into the prepared baking dish, pressing gently to compact slightly.
04 - In a separate bowl, toss crushed cornflakes with 1/4 cup melted butter until well coated. Stir in 1 cup grated cheddar cheese until combined.
05 - Sprinkle the cornflake-cheddar mixture evenly over the potatoes, distributing coverage uniformly.
06 - Bake uncovered for 40 to 45 minutes until the top is golden brown and the casserole bubbles at the edges.
07 - Remove from oven and let rest for 10 minutes to allow the casserole to set before serving.

# Expert Suggestions:

01 -
  • The contrast between the crunchy cornflake-cheddar crust and the silky, cheesy potatoes underneath is genuinely addictive.
  • It comes together in under 20 minutes of prep work, which means you can spend your energy on other dishes instead of hovering over the stove.
  • This casserole feeds a crowd without requiring you to fuss with it once it hits the oven.
02 -
  • Make absolutely sure your hash browns are thawed and excess moisture is drained off, otherwise you'll end up with a watery casserole instead of a creamy one.
  • Don't crush the cornflakes too finely—you want them to stay crispy on top, not turn into dust and disappear into the cheese sauce below.
03 -
  • Grate your cheese fresh right before cooking rather than using pre-shredded, since the anti-caking powder can make the sauce feel slightly grainy no matter how well you stir.
  • If your casserole isn't browning enough after 40 minutes, bump the oven up to 375°F for the final 5 minutes to get that deep golden color without drying out the potatoes underneath.
