Step‑by‑Step Instructions for Buttery Grilled Potatoes in Foil
Step 1: Prepare the Potatoes
Begin by scrubbing the Yukon Gold potatoes under cold water, removing any dirt. Slice them into ¼-inch thick rounds, ensuring uniformity for even cooking. As you cut, admire the beautiful creamy texture of the potatoes, which will shine when grilled. Set them aside for the next steps.
Step 2: Set Up Your Foil
Cut two pieces of heavy-duty aluminum foil measuring 18×12 inches each. Place one piece on a clean surface and layer a thin spread of butter down the center to help prevent sticking. This will be the base for your buttery grilled potatoes in foil, ensuring they cook in rich flavors.
Step 3: Layer the Potatoes
On the buttered rectangle, layer half of the potato slices in an even distribution. Sprinkle them generously with kosher salt, freshly cracked black pepper, minced garlic, and diced onion. Add small pats of butter on top of the first layer to enrich the flavors. This step is crucial for achieving that savory richness.
Step 4: Complete the Layering
Repeat the layering process with the remaining potato slices. Drizzle a bit of olive oil for extra browning and flavor, then top with more seasoned butter. Carefully place the second piece of foil over the layered potatoes, sealing the edges tightly. Make sure there are no gaps to keep the steam in while grilling.
Step 5: Grill the Potatoes
Preheat your grill to medium-high heat, around 350°F. Place the foil packet on the grill and cook for about 15-20 minutes on one side. The potatoes should become tender and take on a lovely golden hue. Keep an eye on the grill to avoid any burning, flipping them halfway through for even cooking.
Step 6: Final Cooking and Serving
After flipping the packet, grill for an additional 10-15 minutes. You’re looking for perfectly tender potatoes that are lightly crisped on the edges. Once done, carefully remove the packet from the grill, allowing it to cool for a few minutes before unwrapping. Serve your buttery grilled potatoes in foil with fresh herbs for a delightful finish!

How to Store and Freeze Buttery Grilled Potatoes in Foil
Fridge: Store leftover buttery grilled potatoes in an airtight container for up to 5 days. Reheat in the microwave or on the stovetop with a splash of additional butter for best flavor.
Freezer: For extended storage, freeze the cooled potatoes in a freezer-safe bag for up to 3 months. Thaw overnight in the fridge before reheating on the grill or in the oven.
Reheating: When ready to enjoy, place the thawed potatoes on the grill or in a preheated oven at 350°F for about 15 minutes, or until heated through and crispy on the edges.
Wrap Tips: If storing in the fridge or freezer, ensure the potatoes are completely cooled before sealing to prevent condensation from making them soggy.
Make Ahead Options
These buttery grilled potatoes in foil are perfect for meal prep, making your summer barbecues even more enjoyable! You can prepare the foil packets up to 24 hours in advance, simply layering the sliced potatoes, garlic, onions, and seasonings before sealing them tightly. To maintain their quality, refrigerate the prepared packets until you’re ready to grill. When it’s time to cook, just place the chilled packets on a preheated grill and follow the usual instructions; grilling may take an extra couple of minutes for perfectly tender potatoes. This way, you can save time on busy weekends while still serving deliciously flavorful buttery grilled potatoes in foil!

Buttery Grilled Potatoes in Foil Recipe FAQs
How do I select the best potatoes for grilling?
Absolutely! For this recipe, Yukon Gold potatoes are ideal due to their creamy texture and rich flavor. Look for firm potatoes without dark spots or blemishes. If you can’t find Yukon Golds, Russet potatoes work too, but remember to peel them for the best results.
How should I store leftover buttery grilled potatoes?
Very simple! Store your leftover potatoes in an airtight container in the fridge for up to 5 days. If you want to reheat them, add a splash of butter in the microwave or on the stovetop for an added touch of flavor.
Can I freeze buttery grilled potatoes in foil?
Yes, you can! Once they have cooled, place the potatoes in a freezer-safe bag, removing as much air as possible. They will keep fresh for up to 3 months. When you’re ready to enjoy them, simply thaw overnight in the fridge before reheating on the grill or in a preheated oven at 350°F for about 15 minutes.
What should I do if my potatoes aren’t cooking evenly on the grill?
If you find your potatoes aren’t cooking evenly, check if your grill is at the right temperature, which should be around 350°F. Also, try to ensure that your potato slices are uniformly cut into ¼-inch thick rounds. If they’re thicker in some areas, they will naturally take longer to cook. Flipping the foil packet halfway through grilling is crucial for even cooking!
Are these potatoes safe for my pets?
While the buttery grilled potatoes are a delicious treat for humans, it’s best to keep them away from pets. Garlic and onions can be toxic to dogs and cats. When serving, simply set aside a portion of plain potatoes without any seasoning or butter for your furry friends instead.
Can I prepare the foil packets ahead of time?
Absolutely! Preparing your foil packets a day in advance is a fantastic idea. Just layer your seasoned potatoes in the foil and refrigerate until you’re ready to grill them. This way, you can enjoy more time with your guests and ensure everything is ready for a delicious cookout!
