How to Grill Sweet Potatoes: A Complete Guide

Grilling sweet potatoes is surprisingly simple and yields a delightfully smoky and caramelized flavor. In short, prepare your sweet potatoes by slicing or cubing, then season generously before grilling over medium heat until tender and slightly charred.

Introduction: Beyond the Fries

Sweet potatoes. Often relegated to casserole dishes drowning in marshmallows, they deserve so much more. Their natural sweetness, vibrant color, and impressive nutritional profile make them a versatile ingredient, and grilling them takes that versatility to a whole new level. Grilling imparts a subtle smokiness that complements their inherent sugars, creating a complex and satisfying flavor that’s equally at home alongside a juicy steak or nestled in a vibrant vegetarian bowl. Forget boiling or baking; grilling unlocks the true potential of this humble root vegetable.

Why Grill Sweet Potatoes? The Benefits

Why should you fire up the grill just for sweet potatoes? Beyond the delicious taste, there are several compelling reasons:

Enhanced Flavor: The smoky char from the grill intensifies the sweet potato’s natural sweetness and adds depth of flavor.
Healthier Cooking: Grilling requires less oil than frying, making it a healthier cooking option.
Versatility: Grilled sweet potatoes can be enjoyed as a side dish, added to salads, used as a topping for tacos, or even pureed into a soup.
Ease of Preparation: Grilling sweet potatoes is surprisingly simple and requires minimal prep time.
Summer Vibes: There’s just something intrinsically summery about food cooked over an open flame.

Choosing the Right Sweet Potatoes

Not all sweet potatoes are created equal. When selecting sweet potatoes for grilling, look for:

Firmness: The sweet potatoes should be firm to the touch, without any soft spots or blemishes.
Smooth Skin: Choose sweet potatoes with smooth, unblemished skin.
Size: Medium-sized sweet potatoes are generally easier to grill evenly. Larger ones may require longer cooking times.
Variety: While any type of sweet potato can be grilled, varieties like Jewel or Garnet tend to have a richer, sweeter flavor and hold up well on the grill.

Preparing Sweet Potatoes for Grilling: Slicing & Dicing

The key to successful grilling lies in proper preparation. You have several options for preparing your sweet potatoes:

Slices: Cut sweet potatoes into 1/4 to 1/2 inch thick slices. This method is great for achieving maximum surface area for caramelization.
Cubes: Cube sweet potatoes into 1-inch pieces. Cubes are ideal for grilling in a basket or on skewers.
Wedges: Cut sweet potatoes into wedges, similar to potato wedges. This method offers a good balance of surface area and tenderness.
Whole: While less common, you can grill whole sweet potatoes by piercing them with a fork several times and wrapping them in foil. This results in a steamed-like texture with a smoky flavor.

Regardless of the method, it’s important to ensure that the pieces are relatively uniform in size to ensure even cooking.

Seasoning & Marinades: Flavor Infusion

Don’t underestimate the power of seasoning! Here are some ideas for flavoring your grilled sweet potatoes:

Simple Seasoning: Olive oil, salt, pepper, and a sprinkle of garlic powder.
Sweet & Spicy: Olive oil, chili powder, cumin, paprika, brown sugar, and a pinch of cayenne pepper.
Herby Goodness: Olive oil, rosemary, thyme, and garlic.
Maple Glaze: Maple syrup, Dijon mustard, and a dash of apple cider vinegar.

You can also marinate your sweet potatoes for 30 minutes to an hour before grilling for an extra burst of flavor.

Grilling Techniques: Direct vs. Indirect Heat

The best grilling technique depends on the thickness of your sweet potatoes.

Direct Heat: Use direct heat for thinner slices or cubes. This method will result in a nice char and caramelization.
Indirect Heat: Use indirect heat for thicker wedges or whole sweet potatoes. This will ensure that the sweet potatoes cook through without burning on the outside. To set up your grill for indirect heat, create two zones: one with the heat source (charcoal or lit burners) and one without. Place the sweet potatoes on the side without the direct heat.

Technique	Sweet Potato Type	Cooking Time (approx.)	Benefit
Direct Heat	Slices, Cubes	8-12 minutes	Maximum caramelization, quick cooking
Indirect Heat	Wedges, Whole Potatoes	20-40 minutes	Even cooking, prevents burning, tender interior

Grilling Sweet Potatoes: Step-by-Step

Here’s a detailed guide to grilling sweet potatoes:

Prepare the Grill: Preheat your grill to medium heat (around 350-400°F).
Prepare the Sweet Potatoes: Wash, peel (optional), and cut the sweet potatoes into your desired shape (slices, cubes, or wedges).
Season the Sweet Potatoes: Toss the sweet potatoes with olive oil and your chosen seasonings. Ensure all pieces are evenly coated.
Grill the Sweet Potatoes: Place the sweet potatoes on the grill grates, either directly over the heat or on the indirect heat side, depending on the thickness and desired level of char.
Cook the Sweet Potatoes: Grill for the recommended time, flipping occasionally, until tender and slightly charred. Use a fork to test for doneness; the sweet potatoes should be easily pierced.
Serve: Remove the sweet potatoes from the grill and serve immediately. Garnish with fresh herbs, a drizzle of honey, or your favorite toppings.

Common Mistakes and How to Avoid Them

Uneven Cutting: Ensure all pieces are roughly the same size to promote even cooking.
Overcrowding the Grill: Don’t overcrowd the grill grates. Leave some space between the sweet potatoes to allow for proper air circulation and even cooking.
High Heat: Grilling over high heat can cause the sweet potatoes to burn on the outside before they are cooked through on the inside. Use medium heat and monitor closely.
Not Seasoning Enough: Don’t be afraid to be generous with your seasonings! Sweet potatoes can handle a lot of flavor.
Under-cooking: Use a fork to test for doneness. The sweet potatoes should be easily pierced when they are cooked through.

Grilled sweet potatoes are incredibly versatile. Here are a few serving suggestions:

Side Dish: Serve as a side dish alongside grilled meats, fish, or poultry.
Salad Topping: Add grilled sweet potato cubes to salads for a boost of flavor and nutrients.
Taco Filling: Use grilled sweet potatoes as a filling for tacos or burritos.
Soup Ingredient: Puree grilled sweet potatoes into a creamy and flavorful soup.
