→ Topping

11 - 1 1/2 cups cornflakes, lightly crushed
12 - 2 tablespoons unsalted butter, melted

# How-To Steps:

01 - Set the oven to 350°F. Grease a 9x13-inch baking dish thoroughly to prevent sticking.
02 - In a large mixing bowl, add thawed hash browns, shredded cheddar cheese, sour cream, 1/2 cup melted butter, whole milk, chopped onion, minced garlic, condensed cream of mushroom soup, salt, and black pepper. Stir until fully incorporated.
03 - Evenly spread the hash brown mixture into the greased baking dish, smoothing the surface with a spatula.
04 - In a small bowl, toss the crushed cornflakes with 2 tablespoons melted butter until coated.
05 - Sprinkle the cornflake mixture evenly over the casserole. Bake in the preheated oven for 45 to 50 minutes, until bubbling and golden on top.
06 - Allow the baked dish to rest for 5 to 10 minutes to ensure clean slices.

# Expert Tips:

01 -
  • The creamy texture paired with a crispy topping makes each bite feel like a treat you never get tired of.
  • It's the kind of dish that disappears at potlucks and leaves everyone asking for the recipe, guaranteed.
02 -
  • If you skip thawing the hash browns, the casserole ends up watery and less flavorful, which I learned the frustrating way.
  • Swapping the topping for breadcrumbs seemed smart once, but the crunch was never close to cornflakes—the magic’s in the unexpected cereal.
03 -
  • Let the casserole cool just enough for clean slices—hot cheese tends to goo everywhere.
  • Shred your own cheese for the ultimate melt and flavor intensity; you’ll notice the difference.
