Start by washing and slicing your Yukon Gold or red potatoes into even, thin rounds or small cubes to ensure uniform cooking.

Toss the sliced potatoes with melted butter, garlic powder, salt, and fresh cracked black pepper until well-coated.

Lay a large sheet of heavy-duty aluminum foil on a flat surface and place the seasoned potatoes in the center, creating a mound.

Generously sprinkle shredded cheddar cheese over the seasoned potatoes.

Carefully fold the foil tightly around the potatoes to seal.

Place the sealed foil packet directly on hot campfire coals or a grill grate and cook for 30-40 minutes, flipping halfway.

Unwrap the foil carefully and garnish with freshly chopped green onions or chives before serving.
