A comforting and easy-to-make twice-baked cheddar potato casserole with a creamy center and a golden, slightly crisp top, perfect for family dinners.

Ingredients

Scale
  • 4 large russet potatoes (about 2 pounds / 900g), peeled and cubed
  • 2 cups sharp cheddar cheese, shredded (about 8 oz / 225g)
  • 4 tablespoons unsalted butter, melted (about 60g)
  • ½ cup sour cream (120ml)
  • ½ cup whole milk (120ml)
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1 teaspoon salt
  • ½ teaspoon freshly ground black pepper
  • 2 tablespoons chopped chives or green onions (optional)

Instructions

  1. Preheat your oven to 375°F (190°C).
  2. Peel and cube the potatoes into about 1-inch pieces and place them in a large pot. Cover with cold water.
  3. Bring to a boil and simmer for 15-20 minutes until potatoes are fork-tender but not mushy.
  4. Drain the potatoes well in a colander and let sit for a few minutes to remove excess moisture.
  5. Mash the potatoes until smooth using a ricer or masher, being careful not to overwork them.
  6. Stir in melted butter, sour cream, and milk. Add more milk if mixture is too stiff, but avoid making it runny.
  7. Add garlic powder, onion powder, salt, and pepper. Stir to combine evenly.
  8. Fold in 1½ cups (6 oz / 170g) of shredded cheddar cheese.
  9. Transfer the mixture into a 9×13-inch baking dish and smooth the top.
  10. Sprinkle the remaining ½ cup (2 oz / 55g) cheddar cheese over the top.
  11. Bake for 25-30 minutes until bubbly and golden with slightly crisp edges. Optionally, broil for 2-3 minutes for a browner top, watching closely to avoid burning.
  12. Remove from oven and let rest for 5 minutes to set.
  13. Garnish with chopped chives or green onions if desired.

Notes

Use fresh shredded sharp cheddar cheese for best melt and flavor. Avoid over-mashing potatoes to prevent a gluey texture. Let casserole rest after baking for easier slicing. For a dairy-free version, substitute butter and cheese with plant-based alternatives and use coconut yogurt instead of sour cream.
