Ingredients to Make Savory Grilled Sweet Potatoes

Flat lay of ingredients used to make Smoky Grilled Sweet Potatoes.

You only need a few things to whip up this delicious side dish.

Most of these ingredients are things I keep on hand all year long.

All you’ll need are some sweet potatoes, avocado oil, some sweetener, and common seasonings.

I use Swerve Brown, a low carb sweetener when I make these sweet potatoes, but you can use regular brown sugar if that’s what you prefer.

I recommend using avocado oil because it works well with the high temperatures of a grill. Coconut oil and grapeseed oil are other great alternatives.

You can use olive oil too, but watch the temperature because you don’t want to exceed 405 degrees F.

Step-by-Step Instructions

Prepping the Sweet Potatoes

Four medium peeled sweet potatoes on a quartz countertop.

Prepping the sweet potatoes is super easy.

I prefer peeling the potatoes when I grill them, but you can skip this step if you want!

Sweet potato skins are safe to eat and contain some great nutrients.

Sweet potatoes cut into 1/2-inch slices on a wood cutting board.

Cut the sweet potatoes into 1/2-inch discs.

If your sweet potatoes are long and skinny, you can cut them in long strips if you prefer.

The key is to get the thickness pretty consistent so they cook at the same rate.

How to Make the Savory Smoky Seasoning

Small glass bowl of seasonings to make smoky sweet potatoes.

You’ll want to combine all the seasonings in a small mixing bowl before adding them to the potatoes.

This makes sure that you don’t get too much of one flavor in a single bite.

Stir all the seasonings together until well-combined, and then sprinkle them over the sweet potatoes that you’ve coated with oil.

Stir the potatoes until the seasonings are evenly coating both sides of each potato.

Now you’re ready to grill!

You can season the potatoes earlier in the day so they’re ready to throw on the grill when you want to cook.

Being able to prepare the potatoes in advance makes this a great dish for entertaining!

How to Make Smoky Grilled Sweet Potatoes without a Smoker

Grill tools required to make smoky grilled sweet potatoes on a regular grill.

I have a gas grill, but I love how smoked foods taste.

I don’t have room for both a smoker and a grill, so I’ve discovered the next best thing: a smoking tube!

You can choose your favorite kind of wood smoking pellets (I love apple wood), and naturally add the flavor of smoke with any kind of grill.

Smoking tube filled with wood pellets that are burning.

When you load the tube, leave about 2 inches empty so the pellets don’t spill out when you lie the smoking tube on its side.

Light the pellets on fire, it takes about a minute with a propane lighter until they begin to flame, then let them burn for a few minutes.

Blow out the flame and place the smoker inside your grill.

Be sure to use grill mitts made for the high temperatures of grilling when you move the smoking tube!

How to Grill Sweet Potatoes

Gas grill with a smoking tube and a stainless steel grill pan.

You can grill the sweet potatoes directly on the grates, but I prefer using a grilling pan like this stainless steel one.

Sweet potatoes can make a little bit of a mess when grilling them, and this grilling pan cleans up so easily!

How to Make Stainless Steel Nonstick

Did you know it’s important to preheat stainless steel before putting anything on it? Preheating it closes its pores and makes it virtually nonstick. Don’t even add cooking spray or oil until it’s been preheated!

Place the seasoned sweet potatoes in a single layer on the grill, close the lid, and cook for 5 minutes.

How do you ensure the sweet potatoes are cooked evenly?

The key is making sure to cut them to the same thickness. Even if they’re different sizes, they’ll still cook evenly if they’re all the same thickness.

What should you do if the potatoes start to burn?

Keep an eye on anything that you cook on the grill to make sure it doesn’t burn.

The seasonings on these sweet potatoes may begin to char, but that just adds more flavor!

If you notice your sweet potatoes are burning, lower the heat and move them to a different part of the grill.

What to Serve with Grilled Sweet Potatoes

Variations and Substitutions

  • Sweet potatoes, red onions, and brussels sprouts
  • Broccoli, cauliflower, and onions
  • Yellow squash, mushrooms, onions, broccoli, and carrots

Tips for Storage and Reheating

To store: Place leftovers in an airtight container and store in the refrigerator up to 5 days.
To freeze: Cool completely. Place leftovers in a single layer in an airtight container and store in the freezer up to 6 months.
To reheat: For best results, reheat on a grill or in a skillet/frying pan. Microwaving will cause them to get soggy. They’re delicious cold over a green salad too!


Can you grill sweet potatoes ahead of time?

Yes, you can grill sweet potatoes ahead of time, however, if you want them to stay firm with a slightly crisp surface you’ll need to reheat them on the grill or in a skillet or frying pan. Grilled sweet potatoes are delicious cold too!

How do you prevent the sweet potatoes from sticking to the grill?

The oil coating the sweet potatoes helps to prevent hem from sticking to the grill. You can also lightly spray the grill grates with a cooking spray designed for the high temperatures of grilling. Nonstick grill mats are another great option.

What type of grill works best for this recipe?

You can use any kind of grill to make these grilled sweet potatoes.
