Grilled Potatoes in Foil

Grilled potatoes in foil are one of my favorite side dishes because they only need 5 ingredients, one foil packet, and no extra pans to clean. Slice the potatoes and onion, wrap them with butter and seasoning, and let the grill do the work while you prepare the rest of the meal.

If you are not grilling, you can bake the same foil packet in the oven. Either way, you get tender, buttery potatoes with very little cleanup.

Why This Recipe Works

Sealing the potatoes and onion in foil traps steam, which helps them cook until tender without drying out. It also makes grilling easier because you do not have to flip each potato slice individually.

This is one of our go-to sides because it uses simple ingredients and cooks right alongside the main dish with no extra pan or burger needed.

Ingredients

• Russet Potatoes – Hold their shape well and cook tender in the foil packet. Yukon Gold or red potatoes also work.
• Onion – Adds extra flavor as it cooks with the potatoes.
• Butter – Adds rich flavor. Olive can also be used.
• Salt and Pepper – Keep the seasoning simple or add your favorite spice blend.

How to Make Foil Pack Potatoes on Grill

Step 1 – Peel the potatoes and slice into 1/4” thick slices.

Step 2 – Peel and thinly slice the onion.

Step 3 – Place foil on the counter and spray with a non-stick cooking spray. I used 1 piece of foil per each potato.

Step 4 – Place the potatoes and onion slices on the foil.  Season each packet with approximately ¼ tsp of the Salt and Pepper and top with 1 Tablespoon of the butter. Adding the butter and seasoning gives the potatoes the perfect amount of flavor.

Step 5 – Fold each foil packet close and seal tightly.

Step 6 – Grill over medium-high heat (about 400 degrees) for 30-40 minutes until the potatoes are tender enough to easily slide a fork through. Check at the 15-20 minute mark so you don’t overcook them.

Step 7 – Remove the heat, be careful when opening the foil packet and enjoy.

Expert Tips

• Heavy Duty Aluminum Foil – We used heavy duty foil to make sure that it doesn’t break when cooking. 
• Carefully Open Foil Packs – After you have finished baking potatoes, be careful open the foil packs. Hot steam will come out when you open the foil packs. Use a fork to pierce the packs before opening, if you prefer.
• Cut Potatoes evenly – Make sure to cut the potatoes about the same size so they cook evenly. Thickness of the potatoes will depend on how long it takes to cook them.
• Serve Immediately – For best results we recommend serving these potatoes immediately.
• Olive Oil – You can use olive oil instead of butter if you prefer. I usually spray the foil with olive oil before adding the potatoes.
• Adding Seasoning – You may need to combine the seasoning in a large bowl with the potatoes to make sure they are coated before adding to the foil.

Additions and Variation Ideas

• Veggies – Feel free to add in vegetables to this potato foil pack. We recommend red bell peppers or green peppers. Slice carrots or mushrooms are always a good addition when making these potatoes.
• Add Meat – Another additions that would be delicious is to add in some protein. We recommend smoked sausage, diced ham, chopped bacon, or Italian Sausage. It adds flavor and could be a complete meal.
• Seasoning – We used simple seasoning when we made this foil pack potatoes dish. There are many different seasoning you can use. You can add in some spice by add in red pepper flakes, cayenne pepper, or chili powder. Other suggestions would be Garlic Powder, Ranch Seasoning, Italian Seasoning or fresh herbs such as rosemary or thyme.
• Potato Swaps – Yukon Gold or red potatoes also work well. Red potatoes may cook a little faster, so check them early.

What Temp Should I Grill Potatoes in Foil?

We recommend grilling potatoes in foil at medium-high heat, or about 400 degrees if your grill has a temperature gauge. Place the foil packets directly over the heat for best results. There’s no need for indirect heat since the foil protects the potatoes from direct flame contact.

How Long to Grill Potatoes in Foil

The potatoes will take about 30 to 40 minutes to grill on medium high heat. Make sure to cut potatoes about the same size and width so they cook in about the same length of time.
