How to Make Creamy Irish Potato Casserole
Ingredients
- 3 lb potatoes (peeled and cut into 1-inch chunks)

- 2 garlic cloves (minced)
- 1 tbsp salt
- 1 tsp nutmeg
- 1 pinch cayenne pepper

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