Ingredients
  

  • 1.2 lb potatoes Maris Piper, King Edward, Russets and the likes.
  • 6 Tablespoons unsalted butter
  • 1 cup sharp cheddar cheese
  • ½ cup mozzarella cheese
  • ½ cup gruyere cheese
  • 3 garlic cloves
  • 3 springs fresh thyme
  • cups Milk You can use up to 2 cups
  • Salt and black pepper to taste
  • 2 Tablespoons parsley finely chopped

Instructions
 

  • Peel the potatoes and cut them into large chunks similar in size so they cook evenly. Place the chopped potatoes in a large pot over high heat and cover with water about 2 inches above them. Add salt, fresh thyme, and garlic and stir briefly to combine.

  • Preheat the oven to 400F /200C.
  • Reduce the heat to medium-high and boil the potatoes until fork tender, about 12-15 minutes. Drain the potatoes completely (remove the thyme stem) and return them to the pot. Let them cool while you heat the milk and butter.
  • In the meantime, Heat the milk and butter in a saucepan until the butter melts. Remove the pan from the heat and set aside.
    6 Tablespoons unsalted butter, 1½ cups Milk
  • Using a potato ricer, handheld masher or electric potato masher, mash the potatoes until smooth and creamy.
  • Slowly pour in the milk and butter mixture, stirring continuously, until well combined. Next, add chopped parsley and season with salt and pepper to taste.
  • Add in the shredded mozzarella, gruyere, and cheddar cheese (reserving some to top the casserole later) and gently fold it into the mashed potatoes.

  • Transfer the mashed potato mixture to a casserole dish and spread the top evenly. Lastly, top with the more shredded cheese.
  • Bake uncovered in the oven until the cheese is melted, bubbly and golden brown, about 20-25 minutes. For a more golden brown crust on top, switch to broil for the last few minutes of baking.
  • Remove the baking dish from the oven and leave to cool slightly.
  • Serve hot as a side dish with your favorite protein, vegetables and gravy for a complete meal.

Notes

Reserve about ½ cup of the mixture of the cheeses used to top the casserole before baking.
Variation and tips
  • Swap whole milk for heavy cream for extra richness Add sour cream, ricotta cheese, or cream cheese for that extra creaminess.
  • Top the casserole with grated parmigiano reggiano or panko breadcrumbs for a crispy topping.
  • Add in chopped, cooked, crispy bacon, green onions, or chives for added flavor and texture.
  • Experiment with different types of cheese, such as blue cheese or gouda, to create unique variations of this recipe.
  • If you don't have fresh thyme, you can use dried thyme instead - just reduce the amount to 1 teaspoon.
  • Swap butter for a plant-based one, and use dairy-free cheese and milk alternatives for a vegan option.
  • Instead of boiling the potatoes with water, use low-sodium chicken or vegetable stock for additional flavor.
