Ingredients

Scale
  • 3 lbs Russet potatoes, scrubbed
  • 1 cup whole milk, warmed
  • 8 tablespoons unsalted butter, softened
  • 1 cup sour cream
  • 1 cup sharp cheddar cheese, shredded, plus 1 cup for topping
  • 4 slices bacon, cooked crisp and crumbled
  • 1/2 cup green onions, sliced
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1/4 teaspoon garlic powder

Instructions

  1. Preheat your oven to 375 degrees Fahrenheit. Lightly grease a 9×13 inch baking dish.
  2. Prick the potatoes several times with a fork. Bake directly on the oven rack for 50 to 60 minutes, or until easily pierced with a knife.
  3. Allow the potatoes to cool slightly, then cut them in half lengthwise and scoop the flesh into a large bowl, leaving a thin layer of potato inside the skins. Discard the skins.
  4. Add the warm milk, butter, sour cream, 1 cup of cheddar cheese, salt, pepper, and garlic powder to the potato flesh. Mash until smooth and creamy.
  5. Fold in the crumbled bacon and half of the sliced green onions into the potato mixture.
  6. Spoon the potato mixture back into the baking dish, spreading it evenly. Do not return the mixture to the skins.
  7. Top the casserole evenly with the remaining 1 cup of cheddar cheese.
  8. Bake for 20 to 25 minutes, or until the cheese is melted and the edges are lightly browned.
  9. Remove from the oven and let it rest for 5 minutes before sprinkling with the remaining green onions. Serve warm.

Notes

  • You can prepare this casserole through step 6 a day ahead. Cover it tightly and refrigerate. Add 10 to 15 minutes to the baking time if baking directly from the refrigerator.
  • For a richer flavor, substitute heavy cream for the milk.
  • If you prefer a crispier top, place the casserole under the broiler for the last 1 to 2 minutes, watching closely to prevent burning.
