Ingredients

Scale

Main Ingredients

  • 2 pounds frozen hashbrown potatoes
  • 1 small onion diced, about 1 cup
  • 5 tablespoons unsalted butter
  • 4 tablespoons all-purpose flour
  • 2 cups milk
  • 2 cups freshly grated cheddar cheese
  • 2 cups sour cream (can also use plain Greek yogurt)
  • 1 teaspoon salt
  • ½ teaspoon black or white pepper
  • ½ teaspoon garlic powder
  • 1 teaspoon chicken bouillon (recommended: Better than Bouillon base)

Topping

  • 1-2 cups corn flakes
  • ½ cup shredded cheddar cheese


Instructions

  1. Preheat and Prepare Dish: Preheat your oven to 400 degrees Fahrenheit. Spray a large 13×8-inch casserole dish with nonstick cooking spray to prevent sticking.
  2. Sauté Onion and Make Roux: Melt 1 tablespoon of butter in a medium saucepan over medium heat. Add the diced onion and sauté until translucent, about 4-5 minutes. Add the remaining 4 tablespoons of butter and once melted, whisk in the flour to create a roux.
  3. Add Milk and Thicken Sauce: Gradually pour the milk into the roux, stirring constantly. Cook over medium heat, stirring frequently until the mixture thickens, about 5-6 minutes.
  4. Season Sauce: Stir in the chicken bouillon until completely dissolved. Add the salt, pepper, and garlic powder. Turn off the heat and let the sauce cool for 4-5 minutes.
  5. Mix Potatoes and Sour Cream: While the sauce cools, place the frozen shredded potatoes in a large bowl and stir in the sour cream until well combined.
  6. Combine Cheese Sauce and Potatoes: Stir 2 cups of shredded cheddar cheese into the warm sauce until melted. Pour this cheese sauce over the potato mixture and stir gently to coat all the potatoes evenly.
  7. Assemble Casserole: Transfer the potato mixture into the prepared casserole dish and spread evenly. Sprinkle the corn flakes over the top, then add ½ cup shredded cheddar cheese as a topping.
  8. Bake: Bake the casserole uncovered in the preheated oven for 45 minutes until the top is golden brown and the casserole is bubbling.
  9. Rest and Serve: Remove from oven and let the casserole sit for 5 minutes before serving to set.

Notes

  • For a healthier option, substitute sour cream with plain Greek yogurt.
  • Use corn flakes topping for a crunchy texture; crushed crackers or breadcrumbs could be an alternative.
  • If preferred, diced fresh onions can be substituted for frozen hashbrowns for a fresher taste.
  • Ensure the sauce is thick enough before mixing with potatoes to avoid a runny casserole.
  • Leftovers can be refrigerated for up to 3 days and reheated in the oven for best texture.
