A creamy and comforting twice baked potato casserole featuring sour cream and fresh chives, perfect for quick weeknight dinners or gatherings.

Ingredients

Scale
  • 45 large baking potatoes (russet or Yukon gold)
  • 4 tablespoons unsalted butter, softened
  • 1 cup full-fat sour cream
  • ½ cup whole milk
  • 1½ cups sharp cheddar cheese, shredded
  • ¼ cup green onions or fresh chives, finely chopped
  • 1 teaspoon garlic powder
  • Salt and freshly ground black pepper, to taste
  • ½ cup bacon bits (optional)

Instructions

  1. Preheat your oven to 400°F (200°C). Wash and dry the potatoes thoroughly. Poke each potato several times with a fork to vent steam and place them on a baking sheet. Bake for about 45-60 minutes until the skins are crispy and a fork slides in easily.
  2. Once baked, let the potatoes cool slightly. When they’re cool enough to handle, slice each potato in half lengthwise. Carefully scoop out the flesh into a large mixing bowl, leaving a thin shell to hold the casserole later.
  3. Prepare the bacon bits (if using): While the potatoes bake, crisp up the bacon in a skillet over medium heat, then drain on paper towels and chop or crumble.
  4. Mash the potato flesh: Add the butter, sour cream, and milk to the bowl. Mash with a potato masher or electric mixer until smooth and creamy but with a bit of texture. Stir in 1 cup of the shredded cheddar, garlic powder, salt, and pepper. Fold in the chopped chives and bacon bits gently.
  5. Spoon the creamy potato mixture back into the potato skins or transfer all to a greased 9×13-inch casserole dish for a family-style presentation. Spread evenly and top with the remaining ½ cup cheddar cheese.
  6. Bake at 375°F (190°C) for another 20-25 minutes until the cheese is melted, bubbly, and golden on top. The casserole should be heated through and thickened slightly.
  7. Let rest for 5 minutes before serving to help it set and make scooping easier.

Notes

If potatoes feel dry when mashing, add a splash more milk or sour cream. For a crunchy topping, sprinkle panko breadcrumbs mixed with butter before the final bake. Do not overmix the potatoes to avoid a gluey texture. Let the casserole rest before serving for cleaner slices.
