Ingredients

Ingredients

  • 4 lb yukon gold potatoes
  • 8 oz Cream cheese
  • 1/2 cup Sour cream
  • 1 tbsp Onion Powder
  • 1 tbsp Fresh Thyme Leaves
  • 1 tsp smoked paprika
  • 1/4 tsp Cayenne pepper
  • Monterey Jack Cheese
  • Salt
  • 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

  • 4 tbsp butter
  • 1 tbsp Garlic powder

for finishing

  • 6 tbsp butter
  • 2 tsp Garlic powder

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, to 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, to 40 minutes. Top with parsley or thyme. Serve them up and enjoy!

Ago's Notes

  • Adjust salt to taste based on your canned goods.

Let the warmth of the potatoes and the gentle tang of cream cheese carry you through each bite-this dish is a testament to how simple ingredients, when treated with care, can create something deeply satisfying and universally comforting.
