How to Make Grilled Potato Fans with Onions
-
Preheat the grill: Start by heating your grill to an indirect heat setting. This is crucial for evenly cooking the potato fans without burning them, about 350°F will do nicely.
-
Slice the potatoes: Carefully cut each medium-sized potato into 1/2-inch slices, but don’t cut all the way through! Fan them slightly to allow for even grilling and filling later on.
-
Prepare the foil: Place each potato on a generous square of heavy-duty foil. Insert onion halves, dollops of butter, and minced garlic between the fan cuts, savoring that fragrant combination.
-
Mix the flavors: In a separate bowl, combine grated Parmesan cheese, chopped chives, crushed red pepper flakes, and salt. Sprinkle this flavorful mix generously between the potato slices, packing in all that goodness!
-
Wrap and grill: Tightly wrap the foil around the potatoes to seal in steam, and grill covered for 35-45 minutes. Keep an eye on them, and use a fork to check for tenderness; they should be soft to the poke.
Optional: Serve with a sprinkle of fresh herbs for an extra pop of flavor.

Expert Tips for Grilled Potato Fans
• Choose the Right Potatoes: Use medium-sized potatoes for uniform cooking; larger varieties may not grill evenly and can result in undercooked centers.
• Layer of Flavor: Don’t skip the seasoning! Properly salt the potatoes and sprinkle enough cheese and garlic in each slice to enhance the overall flavor of your Grilled Potato Fans with Onions.
• Watch the Grill: Maintain indirect heat to avoid burning. High direct heat can lead to crispy outsides and undercooked insides, so aim for around 350°F.
• Seal Carefully: Ensure that the foil is tightly wrapped around the potatoes. A good seal prevents drying out and locks in moisture while grilling.
• Check for Doneness: After the suggested grilling time, poke the potatoes gently with a fork. If they’re tender and give easily, they’re ready to enjoy!
