How To Make Cheesy Mashed Potatoes:

Peel and chop the potatoes. Add to a large pot, cover with cold water, and heat over medium-high heat. Bring to a boil, add 1 teaspoon of salt, and stir to combine. Continue to boil the potatoes until fork tender, approximately 20 minutes.

Top with the potatoes with the remaining shredded cheese in an even layer. Bake for 15 minutes until cheddar cheese has melted. Turn the oven to broil on high and bake an additional 4-5 minutes or until the top layer of cheese is golden and crispy as desired.

Top with chopped chives before serving. Serve with Jalapeño Honey Ham, Prime Rib, or Oven Baked Beef Ribs.

Make Ahead

Prepare the cheesy mashed potato recipe according to directions, but instead of baking, cover and store in the refrigerator for up to 3 days. Remove the dish from the fridge and set on counter while oven preheats (to avoid putting a cold dish in the hot oven). Bake at 350 degrees F for 30 minutes or until warmed through.

Storage

  • Leftovers: Store covered in the refrigerator for 3-5 days.
  • Freezer: Store in a freezer-safe sealed container for up to 3 months. Thaw in the refrigerator overnight.
  • Reheating: Reheat leftover potatoes in a skillet on the stovetop, mixing in some milk or cream as needed to thin and get a creamy texture again.

Variations

  • Cheeses: The type of cheese used can be swapped for white cheddar, parmesan, gruyere, Monterey Jack, or Fontina.
  • Herbs: Swap out the chives for another herb or mix the herbs into the potatoes with the cheese before baking.
