  • 1 cup (240 ml) sour cream
  • 1/2 cup (115 g) unsalted butter, melted
  • 1 cup (240 ml) whole milk
  • 1 small onion, finely chopped
  • 2 cloves garlic, minced
  • 1 can (10.5 oz / 300 g) condensed cream of mushroom soup
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1 1/2 cups (90 g) cornflakes, lightly crushed
  • 2 tablespoons unsalted butter, melted

Instructions

1. Preheat the oven to 350°F (175°C). Grease a 9x13-inch (23x33 cm) baking dish.
2. In a large bowl, combine the thawed hash browns, cheddar cheese, sour cream, melted butter, milk, onion, garlic, cream of mushroom soup, salt, and pepper. Mix until well blended.
3. Spread the mixture evenly in the prepared baking dish.
4. In a small bowl, toss the crushed cornflakes with 2 tablespoons melted butter. Sprinkle evenly over the casserole.

Zusatztipps für die Zubereitung

Ensure the hash browns are fully thawed and drained of excess moisture for the best creamy texture. Finely chop the onion and garlic to distribute flavor evenly throughout the casserole. Toss the cornflakes gently with melted butter to avoid sogginess and create a crispy topping. Letting the casserole rest before serving helps it set for cleaner slices.

Recipe FAQs

Can I use fresh potatoes instead of frozen hash browns?

What can I substitute for cream of mushroom soup?

How do I make the topping extra crispy?

Toss the cornflakes with melted butter right before sprinkling and bake until they turn a deep golden brown.

Can I prepare this dish ahead of time?

Yes, assemble everything except the topping and refrigerate overnight. Add cornflakes just before baking to keep them crisp.

Are there optional add-ins for extra flavor?

Stir in chopped scallions, cooked bacon, or diced bell peppers to boost flavor and add variety to the dish.

Is this casserole suitable for vegetarians?
