Ingredients

  • 8 medium russet potatoes Yukon gold also works, baked and warm
  • 4 tbsp unsalted butter room temperature
  • cup sour cream or use Greek yogurt
  • cup heavy cream plus more as needed
  • 1 tsp salt
  • ½ tsp ground black pepper
  • 2 cups Colby Jack cheese or your favorite, shredded, divided
  • 8 slices bacon cooked and crumbled, divided
  • 5 green onions chopped, divided

Instructions

  • Preheat oven to 450°F. Wash the potatoes, then pierce them all over with a fork and bake until soft and tender, about 45 minutes.
    8 medium russet potatoes
  • Lower the oven to 375°F. Spray a 1½ quart baking dish with nonstick spray. Set aside.
  • Slice the warm baked potatoes in half length-wise. Scoop the potato flesh out of the potato skins and place into a large mixing bowl. Add the butter and use a potato masher to mash the potatoes.
    4 tbsp unsalted butter
  • Stir in the sour cream, heavy cream, salt, and pepper. For a creamier casserole, add a little more cream.
    ⅔ cup sour cream, ⅓ cup heavy cream, 1 tsp salt, ½ tsp ground black pepper
  • Add 1 cup of cheese, half of the bacon, and half of the green onions. Mix well.
    2 cups Colby Jack cheese, 8 slices bacon, 5 green onions
  • Transfer the potato mixture to the prepared baking dish. Spread into an even layer and top with the remaining cheese and bacon.
  • Cover the dish with aluminum foil and bake for 20 minutes.
  • Remove the foil and bake for 10 more minutes, or until the cheese is melted and the casserole is warmed through. Garnish with green onions and serve.

Notes

  • Use as much or as little bacon as you like, or use turkey bacon. 
  • To get a bubbly, browned cheese top, remove the foil at the end of baking
  • For the best flavor use full fat sour cream.
  • Freshly grated cheese will melt and taste better. 
  • Store the potato skins in the fridge for another recipe. 
  • Fresh potatoes are best, but pre-made (or leftover) mashed potatoes will work.
  • Store leftovers in an airtight container in the refrigerator for up to 4 days.
