Parmesan Crusted Mashed Potatoes are creamy, crunchy and have a slightly spicy kick that can’t be beat! The parmesan cheese adds the perfect notes of cheesiness to the whole dish making these mashed potatoes shine.

I was surprised when serving this for dinner. When I scooped them out (the sides and bottom of the potatoes) the ones touching the sides of the dish, had crisp-i-fied too while they cooked! YUM. I love crispy mashed potatoes. Don’t you?

Parmesan Crusted Mashed Potatoes

Serves: 6       Total Time: 50 Minutes


  • 5 fist sized russet potatoes, scrubbed, peeled, and cut into 2-inch chunks
  • 4 tbsp. butter – divided
  • 1 to 2 tbsp. horseradish mayonnaise
  • 1 clove garlic, grated
  • ¼ cup heavy cream
  • ¼ cup shredded parmesan
  • salt and pepper to taste
  • small handful of fresh chives, chopped

Parmesan Topping

  • 3/4 cup shredded parmesan cheese
  • ¼ cup panko breadcrumbs
  • 2 tsp. parsley
  • ½ tsp. cayenne pepper 


Step 1
Fill a pot of water until it just covers the cut potatoes. Bring the pot to a boil and cook the potato chunks until fork tender.
Step 2
While the potatoes are cooking, combine the ingredients for the parmesan topping in a small bowl, tossing to mix thoroughly.
Step 3
Remove the potatoes from the heat, drain, and replace on the still warm burner. Add 2 tbsp. butter, heavy cream, horseradish mayonnaise, shredded parmesan, salt and pepper to taste. Mash the potatoes until they’re smooth.
Step 4
Butter a shallow, heatproof dish with 1 tbsp. butter. Spread the potatoes out in the dish. For fun, create a lovely design in the top. Remember, presentation is everything.
Step 5
Cover the top of the potatoes with the breading mix. Melt the last tablespoon of butter and drizzle it over the topped potatoes.
Step 6
Bake the whole dish on a preheated grill for 20 to 30 minutes until the top is golden and everything is heated through.
Step 7
Serve right away topped with some chopped fresh chives.
