Ingredients

  • 1 teaspoon freshly cracked black pepper
  • 1 30-ounce / 850g package frozen grated hashbrown-style potatoes
  • 2 cups thick cultured sour cream 480g
  • ½ cup melted unsalted butter 113g
  • 1 small yellow onion minced finely
  • 1 teaspoon coarse kosher salt
  • 1 10.5-ounce / 298g tin condensed cream of chicken soup
  • 3 cups shredded sharp cheddar separated (12 ounces / 338g)

Instructions

  • Set your oven to preheat at 350°F (175°C). Pour the melted butter into a 9×13-inch baking dish, tilting the dish gently to coat the bottom evenly.
  • In a large bowl, combine the sour cream, condensed soup, 2 cups of the shredded cheese, diced onion, kosher salt, and ground black pepper. Stir until thoroughly mixed.
  • Gently fold in the frozen shredded hashbrown potatoes, ensuring all the pieces are evenly coated in the creamy mixture.
  • Transfer the mixture into the prepared casserole dish, spreading it out evenly. Top with the remaining 1 cup of cheddar cheese, distributing it uniformly over the surface.
  • Place the dish in the oven and bake for 45 to 50 minutes, or until the edges are golden and the center is hot and bubbly. Allow the casserole to rest for 15 minutes before serving.

Notes

For a crispy topping, consider sprinkling the surface with butter-coated panko, cornflakes, or crushed buttery crackers. To prevent burning, tent the dish loosely with foil and uncover it during the last 5 to 10 minutes of baking.
Frozen diced hashbrowns may be substituted if shredded versions are unavailable.
Feel free to replace cheddar with any easily melting cheese such as Monterey Jack, Gruyere, provolone, pepper jack, or mozzarella.
To incorporate protein, stir in cooked and chopped chicken, crumbled bacon, or cubed ham before baking.
If you prefer a spicy twist, add finely chopped jalapeños to the mixture before baking.
