A rich, fluffy mashed potato casserole loaded with sharp cheddar, crispy bacon, and chives. This holiday favorite uses Yukon Gold potatoes and a specific technique to ensure a creamy, lump-free texture that is perfect for any occasion.

Ingredients

Scale
  • 3 lbs Yukon Gold potatoes, peeled and cut into 2-inch chunks
  • 1/2 cup unsalted butter, room temperature
  • 1 cup heavy cream, warmed
  • 1/2 cup sour cream, full-fat and warmed
  • 2 cups sharp cheddar cheese, freshly shredded
  • 8 slices bacon, cooked until crispy and crumbled
  • 1/4 cup fresh chives or green onions, sliced
  • 1 tsp garlic powder
  • 1/4 tsp nutmeg
  • Sea salt and black pepper, to taste

Instructions

  1. Preheat oven to 350°F (175°C).
  2. Place potato chunks in a large pot of salted cold water. Bring to a boil, then reduce to a simmer and cook for 15-20 minutes until tender.
  3. Drain potatoes thoroughly and return them to the hot pot for 1 minute to evaporate excess moisture.
  4. Rice or mash the hot potatoes into a large mixing bowl. Add butter and stir until melted.
  5. Slowly whisk in the warm heavy cream and sour cream until smooth. Add garlic powder, nutmeg, salt, and pepper. Taste and adjust seasoning.
  6. Transfer the mixture to a 9×13 baking dish and smooth the top. Sprinkle half of the cheddar cheese evenly over the top.
  7. Bake for 15 minutes until hot and cheese is starting to melt.
  8. Remove from oven and sprinkle remaining cheese, crispy bacon bits, and chives on top.
  9. Switch oven to broil and broil for 2-3 minutes until cheese is golden and bubbly. Watch closely to prevent burning.
  10. Let rest for 5 minutes before serving.

Notes

Ensure potatoes are drained thoroughly to avoid a soupy casserole. Warm the cream and sour cream before adding to prevent the butter from solidifying. For best melting results, shred your own cheese and toss with a teaspoon of cornstarch. This recipe is naturally gluten-free, but check bacon and cheese labels for hidden additives.
