📝 Why You’ll Love This Recipe
They are healthy and loaded with nutrients. This is perfect for folks trying to reduce their carbs.
The preparation for this recipe is super simple! It only takes five minutes to prepare the sweet potatoes and get them on the grill. You don’t even need to boil them before getting them on the grill, saving even more time.
You need just three ingredients to make this recipe and you probably have them all at home already.
Cleanup is a breeze. You don’t need to dirty and dishes and the aluminum foil is easy to just throw away when the grilling is done.
Sweet Potato | The serving size is one sweet potato, but you can make as many as you need. They are perfectly sweet and delicious. I recommend making several at a time. It doesn’t take much extra time to prepare them, and they store wonderfully in the fridge. For the foil recipe, it doesn’t matter How Many Potatoes in a Pound.
Olive Oil | A little bit of olive oil will help the skin crisp up beautifully.
Sea Salt | Add a pinch to the potatoes to really get an amazing flavor. Stay away from table salt as it is so finely ground that it doesn’t work well. Stick with Coarse Ground Sea Salt or Kosher Salt.
⏲️ Equipment and Tools
Aluminum Foil Packet – Because this recipe uses indirect heat, you don’t need a heavy duty foil. Stick with your kitchen foil.
BBQ Tongs – I highly recommend some dedicated BBQ tongs. The key is to get a long-handled version so your arms aren’t over the hot coal. Trust me, I learned that the hard way!
Step One: Cut off a piece of foil and lay it out on the counter. Poke a few holes in a clean sweet potato with a fork. The holes will help the steam escape easily.
Step Two: Use a little bit of olive oil spray to provide a very light coat on the sweet potato. Sprinkle with sea salt or kosher salt.
Note: I find the combination of the coarse salt and the oil help the skin get a little crispy when it is done grilling.
Step Three: Wrap the sweet potato up and seal the aluminum foil tight.
Step Four: Place the wrapped sweet potato on a heated grill set to 350°F (or a medium-high temperature). I used indirect heat by adding the plate setter to the grill.
Note: For gas grills, turn off the burners immediately under the potato. This creates an indirect heat zone that will serve the same purpose.
Step Five: Grill for about 40 minutes, turning half way for a medium sized potato. My sweet potatoes were quite large, and I needed another 20 minutes until they were fork tender. You’ll know they are done when a fork easily sticks into the sweet potato.
Step Six: Serve with your favorite toppings. For this one, we added a pad of butter and some pepper.
💡 Recipe Tips and Tricks
Skip the foil for a crispy skin. Place it straight on the grill grate. The outside will become very crispy but the inside will still be soft and fluffy. Make sure to really watch it closely as it is very easy for the potato to burn. Either way, you can make this yummy side with minimal effort and yet, a high return on flavor!
This is a perfect recipe to serve at a cookout. Prepare and wrap the sweet potatoes at home and throw them on the grill at your BBQ. I keep them off to the side while I am grilling rest of the dishes.
For this recipe, I called for using Olive Oil, but if you have Avocado Oil, I would use that instead. It isn’t worth an extra trip to the store to grab it, but Avocado Oil is a bit healthier and has a more mild, smooth flavor.

🧑🍳 Storage and Reheating
If you make a few extras (and WHY WOULDN’T YOU?), they store great in the refrigerator for up to about three days.
After you remove them from the grill, let them cool completely and simple set them in the refrigerator. Since they are already wrapped in foil, you don’t need to add them to another container.
You can freeze these as long as they are cooked. Don’t try to freeze uncooked sweet potatoes – it just doesn’t work well.
After the grilled sweet potatoes have cooled completely, remove them from the foil and wrap them in Saran or Press N Seal. Place them inside a freezer safe Ziploc bag and store them for up to 90 days.
To reheat them, you can put them back on the grill, in the microwave or the oven. But, my favorite solution is to throw them in the Air Fryer. The outside will crisp up and the results are amazing!
Additions and Substitutions
Change up the seasonings. I used a simple salt and olive oil combo, but try to add some smoky paprika, rosemary, thyme or even add some heat with red pepper flakes. If you are serving kids, make sure they don’t mind a little heat with their sweet potato.
One of my favorite alternate topping is whipped butter and candied pecans or walnuts. This adds a very light buttery flavor and I can’t seem to get enough of the crunch from the nuts.
Nothing goes better with a nice buttery grilled sweet potato than a juicy steak! Try this Grilled Teres Major recipe, Grilled Ribeye Cap, or even a nice big Grilled T-bone Steak. Nice juicy burgers are another good main course to consider. Try our Travis Scott Burger, or if you don’t have much time, consider grilling them straight from a frozen patty.
Don’t forget your veggies! I typically move the sweet potatoes to the side of the grill when I am making other dishes, so focus on ones that won’t take a lot of time. Grilled Parsnips only take about 15 minutes to whip up, and offer a tangy flavor that complements the sweetness of these potatoes. For a more traditional veggie, aim for these Grilled Broccolini. The only take 15 minutes as well.

Do you Need to Pole Holes in Sweet Potatoes Before Grilling?
I have have heard stories about potatoes bursting when the steam accumulates inside the skin and can’t escape fast enough, but I have never had that happen to me. It takes just a second or two to use a fork to poke holes in the skin which will allow the steam to escape, so it is worth the time.
There are so many ways to jazz up these potatoes. Be creative!
Butter and brown sugar
Butter and sour cream
Make it taco stuffed by using black beans, corn, red onions, and topping with sour cream or guacamole.
Make Cowboy Caviar and top the sweet potatoes with it
Use these for breakfast meal prep and add scrambled eggs, bacon chunks, and tomatoes
Top with homemade salsa, green onions, and a dollop of sour cream
Load it with homemade chili, cheese, and sour cream
Alternatively, bake them on the grill and remove the insides and whip them into a mashed sweet potato – all done without ever having to use your oven.
Any way you choose to enjoy these delicious Sweet Potatoes, you are going to love them! Pair them with a dish indoors or your favorite pulled pork, grilled steak, or grilled chicken recipe.
Rub the outside lightly with oil, sprinkle with sea salt, wrap in foil and grill at a medium high heat for about 40 minutes or until it is easy for a fork to poke it.
If you are grilling these whole, then there is no need to soak them. If you are slicing them, then soaking will help remove the starches from the cut areas and will help those surfaces get crispy.
