Mashed Potato Casserole

Ingredients

Ingredients

  • 4 lb yukon gold potatoes
  • 8 oz Cream cheese
  • 1/2 cup Sour cream
  • 1 tbsp Fresh Thyme Leaves
  • 1 tsp smoked paprika
  • 1/4 tsp Cayenne pepper
  • 1/3 tsp Salt
  • 3/16 tsp pepper
  • 1 1/2 cup Milk
  • 2 egg beaten
  • 2/3 cup panko bread crumbs
  • 2/3 cup corn flakes
  • 2/3 cup gruyere cheese

for initial mix

  • 8 tbsp butter
  • 1 tbsp Onion Powder
  • 1 tbsp Garlic powder
  • 1 cup Monterey Jack Cheese

for finishing

  • 6 tbsp butter
  • 2 tsp Garlic powder

Equipment

  • Dutch Oven
  • Skillet

Instructions

  1. 1

    Preheat the oven to 375°F. Butter a 9x13-inch casserole dish.

  2. 2

    In a Dutch oven, cover the potatoes with water and boil over high heat until tender, 10-15 minutes. Drain and add them back into the hot pot. Using a hand mixer or potato masher, mash the hot potatoes with the butter, cream cheese, sour cream, onion powder, garlic powder, thyme, paprika, cayenne, Monterey jack, salt, and pepper. Gradually mix in the milk and eggs, don’t over-mix.

  3. 3

    Scrape the potatoes into the buttered casserole dish.

  4. 4

    Make the topping. Melt the butter in a skillet over medium heat until it begins to brown, about 3 minutes. Remove from heat and stir in panko, corn flakes, and garlic. Season with salt and pepper. Sprinkle over the potatoes. Top with grated Gruyère.

  5. 5

    Bake until golden and crisp, about 40 minutes. Top with parsley or thyme. Serve them up and enjoy!

Ago's Notes

  • Adjust salt to taste based on your canned goods.

This Mashed Potato Casserole is a warm and inviting dish that showcases simple ingredients in their best light. While it may not quite match the refined simplicity of traditional Italian pasta dishes, its creamy richness and comforting texture make it an excellent choice for a heartwarming meal.
