  • Total Time: 1 hour
  • Yield: 6-8 servings 1x

Ingredients

Scale

Base Ingredients:

  • 4 cups potatoes, peeled and diced (or frozen hashbrowns)
  • 2 cups shredded cheese (cheddar, Colby Jack, or a mix)
  • 1 cup sour cream
  • 1 cup milk
  • ½ cup butter, melted
  • 1 small onion, finely chopped
  • 2 cloves garlic, minced
  • 1 teaspoon salt
  • ½ teaspoon black pepper
  • ½ teaspoon paprika

Optional Add-Ins:

  • Protein: Cooked shredded chicken or turkey
  • Vegetables: Bell peppers, mushrooms, or spinach
  • Crunchy Topping: Crushed cornflakes, breadcrumbs, or Ritz crackers

Instructions

  • Prepare the Potatoes: If using fresh potatoes, peel and dice them. If using frozen hashbrowns, let them thaw for 10 minutes.
  • Make the Creamy Mixture: In a large bowl, combine melted butter, sour cream, milk, minced garlic, and chopped onions. Stir in salt, pepper, and paprika.
  • Mix Everything Together: Add the potatoes to the bowl and mix well. Stir in 1 ½ cups of shredded cheese, saving ½ cup for topping.
  • Assemble the Casserole: Preheat the oven to 375°F (190°C). Grease a 9×13-inch baking dish and spread the potato mixture evenly.
  • Add the Topping: Sprinkle the remaining ½ cup of cheese on top. For extra crunch, add crushed cornflakes or breadcrumbs.
  • Bake to Perfection: Bake for 40-45 minutes or until the top is golden and bubbly.
  • Let It Rest & Serve: Allow the casserole to rest for 5-10 minutes before serving to enhance texture and flavor.

Notes

  • Make Ahead Tip: Assemble the casserole a day in advance, cover, and refrigerate. When ready, bake as directed, adding 10 extra minutes to the cook time.
  • Storage: Leftovers can be refrigerated for up to 4 days or frozen for up to 3 months.
  • Reheating: For best results, reheat in the oven at 350°F (175°C) for 20-25 minutes until warmed through.
