Ingredients

For the Mashed Potatoes:

  • 4 pounds russet potatoes peeled, sliced into 3/4-inch-thick rounds, and rinsed thoroughly
  • 1/2 cup unsalted butter melted
  • 1 cup half-and-half warmed
  • 1 teaspoons salt
  • 1/4 tsp ground black pepper
  • 1/4 tsp nutmeg
  • 2 tsp dijon mustard

For the Apple Sauerkraut:

  • 25 oz sauerkraut drained
  • 1 cup apple cider
  • 2 bay leaves
  • 2 medium apples peeled, cored, and chopped
  • 1 teaspoon cumin seeds optional
  • salt and pepper

For the Topping:

  • 2 tbsp unsalted butter
  • 1 cup panko breadcrumbs
  • 1/4 cup fresh parsley finely chopped
  • Salt and pepper
  • 2 cups shredded cheddar

Instructions

  • Preheat the oven to 350°F.
  • Place the potatoes in a large pot or dutch oven and cover with 1 inch of water. Bring to a boil over high heat, then reduce to a simmer and cook until the potatoes are tender, about 15 minutes.
  • Meanwhile, in a medium saucepan combine sauerkraut, apple cider, bay leaves, chopped apples, and cumin seeds. Bring to a boil and let simmer with the lid on for 15 minutes until the apples. Season with salt and pepper.
  • When the potatoes are tender, drain them in a colander. Process the potatoes with a potato ricer into a large bowl or use a potato masher for chunkier mashed potatoes. Stir in the melted butter, warm half-and-half, salt, pepper, nutmeg, and Dijon.
  • For the topping, heat 2 tbsp butter in a skillet over medium-high heat. Add the breadcrumbs and toast them while stirring constantly until golden brown, about 1-2 minutes. Take them off the heat and let them cool, then toss them with the parsley and season with salt and pepper to taste. Set aside.
  • Transfer the apple sauerkraut into a 13 by 9-inch baking dish, spread mashed potatoes on top, and sprinkle the cheddar cheese evenly over the mashed potatoes, followed by the breadcrumbs.
  • Bake the casserole until the cheese is melted and the breadcrumbs are crisp and browned, 25 to 30 minutes.
