Ingredients

Main Ingredients

  • 3 lb potatoes, peeled and cut into 1-inch chunks
  • 6 tbsp butter, unsalted (recommended: Kerrygold)
  • 1.25 cups cream
  • 3 green onions, thinly sliced about 1/8-inch rounds
  • 2 cloves garlic, minced
  • 1 tbsp salt
  • 1 tsp nutmeg
  • 1 pinch cayenne pepper
  • Pepper to taste
  • 0.5 tsp fresh thyme, chopped
  • 1.25 cups cheddar cheese (recommended: Tillamook sharp cheddar)
  • 1.5 tbsp butter, melted and cooled to room temperature
  • 0.5 tsp nutmeg

Method

Preparation

  • Preheat your oven to 350°F (175°C).
  • Boil the potatoes in a large pot of salted water until tender, about 15-20 minutes. Drain well.
  • In a large bowl, mix together the butter, cream, green onions, minced garlic, salt, nutmeg, cayenne pepper, and pepper.
  • Add the drained potatoes to the bowl and gently mix until the potatoes are coated.
  • Transfer half of the potato mixture to a baking dish, sprinkle half of the cheddar cheese on top, and then add the remaining potato mixture. Top with the rest of the cheese.
  • Drizzle the melted butter over the top and sprinkle with fresh thyme.

Baking

  • Bake in the preheated oven for 25-30 minutes, or until the cheese is bubbly and golden brown.

Notes

Serve this casserole hot right out of the oven. It pairs perfectly with roasted meats, salads, or even as a standalone dish. For an added touch of freshness, consider garnishing it with more sliced green onions or a sprinkle of fresh herbs. Ensure your potatoes are cut evenly for consistent cooking. Experiment with different cheeses or add cooked bacon for extra flavor. For a bit of crunch, you can top the casserole with breadcrumbs before baking.
