Ingredients Method Notes

Ingredients
  

  • Ingredients You’ll Need
  • 6 –8 medium russet potatoes
  • 1 cup sour cream
  • ½ cup milk
  • 4 tablespoons butter
  • 2 cups shredded cheddar cheese
  • 6 slices bacon cooked until crisp and crumbled
  • 1 teaspoon salt
  • ½ teaspoon black pepper
  • ½ teaspoon garlic powder
  • 2 tablespoons chopped fresh chives

Method
 

Step 1: Bake the Potatoes

Preheat your oven to 400°F (200°C). Scrub the potatoes clean and pat them dry. Use a fork to poke several holes in each one to allow steam to escape. Place them directly on the oven rack and bake for about 50–60 minutes, until they feel soft when pierced with a fork. Let them rest for 10 minutes so they’re cool enough to handle.

    Step 2: Prepare the Creamy Filling

    Cut each potato in half lengthwise. Carefully scoop the soft interior into a large mixing bowl, leaving the skins mostly intact. Add butter, milk, sour cream, salt, pepper, and garlic powder to the warm potato flesh. Mash everything together until smooth and fluffy. Fold in most of the shredded cheddar, crispy bacon crumbles, and chopped chives. Save a little of each for topping later.

      Step 3: Assemble and Bake Again

      Spoon the creamy mixture back into the potato skins, slightly overfilling each half for a generous look. Arrange them in a baking dish. Sprinkle the reserved cheese, bacon, and chives over the top. Lower the oven temperature to 375°F (190°C) and bake for 20–25 minutes, until the cheese melts and the tops turn lightly golden. Serve hot and enjoy that creamy center with the crispy, cheesy finish.

        Notes

        Make-Ahead Instructions

        You can assemble the stuffed potatoes up to three days ahead of time. After filling and topping them, cover tightly with foil or plastic wrap and refrigerate.
        When ready to bake, remove from the fridge, uncover, and bake as directed. You may need to add a few extra minutes if baking straight from cold.

        Storage and Reheating

        Store leftovers in an airtight container in the refrigerator for up to four days.
        To reheat, place them in a 350°F oven for 15–20 minutes until warmed through. Avoid microwaving if possible — the oven keeps the texture much better.
        You can also freeze them. Let them cool completely, wrap tightly, and freeze for up to two months.

        Customization Ideas

        Vegetarian Version

        Skip the bacon and replace it with sautéed mushrooms, roasted broccoli, caramelized onions, or diced bell peppers for extra flavor and texture.

        Dairy-Free Option

        Swap the milk for almond or oat milk. Use plant-based butter and dairy-free cheese alternatives. Nutritional yeast adds a cheesy flavor boost.

        Flavor Boosters

        Mix in ranch seasoning, smoked paprika, green onions, or even a sprinkle of Parmesan on top for extra depth.
