1 Butter the inside of a cast iron skillet and layer half the potato slices on the bottom. Top with half the onions. Season with salt and pepper.
2 Sprinkle 1 cup of the cheese over the potatoes and onions and dot with half the butter. Layer the remaining potatoes and onions on top. Dot with remaining butter.
3 Pour the milk into the skillet. Cover the skillet tightly with aluminum foil.
4 When ready to cook, set Grill temperature to 350˚F and preheat, lid closed for 15 minutes.
5 Bake for 1 hour, or until the potatoes are very tender.
6 Remove the foil and top with the remaining 1/2 cup of cheese. Bake for 30 minutes more (uncovered) until the cheese is lightly browned. Dust the top with paprika and serve immediately. |
