How to Cook Sweet Potatoes on the Grill: A Guide to Smoky Sweetness
Grilling sweet potatoes unlocks a delightful smoky flavor and caramelizes their natural sugars. You can grill them whole, sliced, or cubed, offering a versatile side dish that’s both delicious and nutritious, making it a perfect addition to any barbecue.
Why Grill Sweet Potatoes? The Benefits Unveiled
Grilling sweet potatoes transforms them from a simple root vegetable into a culinary star. The high heat caramelizes their natural sugars, creating a sweet and slightly smoky flavor that complements a wide range of grilled meats and vegetables. Beyond the taste, grilling offers several other advantages:
- Healthier Cooking: Grilling requires minimal oil, making it a healthier alternative to frying or baking.
- Enhanced Flavor Profile: The smoky char from the grill adds complexity and depth to the sweet potato’s natural flavor.
- Convenience: Grilling sweet potatoes alongside your main course simplifies meal preparation.
- Textural Variety: Depending on how you prepare them, you can achieve a variety of textures, from tender and creamy to slightly crispy.
Choosing the Right Sweet Potatoes
Selecting the right sweet potatoes is crucial for achieving optimal grilling results. Look for:
- Firmness: Choose sweet potatoes that are firm to the touch, without any soft spots or blemishes.
- Smooth Skin: Opt for sweet potatoes with smooth, unblemished skin. Avoid those with cuts, bruises, or signs of sprouting.
- Size and Shape: Select sweet potatoes that are relatively uniform in size and shape for even cooking. Medium-sized sweet potatoes generally cook faster and more evenly than very large ones.
- Variety: While many varieties will work, Beauregard and Garnet sweet potatoes are known for their sweetness and moist texture, making them excellent choices for grilling.

Step-by-Step Guide to Grilling Success
Here’s a comprehensive guide to grilling sweet potatoes using all three methods:
- Preparation:
- Wash sweet potatoes thoroughly.
- For whole sweet potatoes, prick them several times with a fork to allow steam to escape.
- For slices, cut into ½-inch thick rounds.
- For cubes, cut into approximately 1-inch pieces.
- Seasoning:
- In a bowl, toss the sweet potatoes with olive oil, salt, pepper, and any desired spices (cinnamon, paprika, garlic powder are all great options).
- A light coating of oil prevents sticking and enhances browning.
- Grilling:
- Preheat your grill to medium heat (around 350-400°F or 175-200°C).
- Whole Sweet Potatoes: Place directly on the grill grates and cook for 45-60 minutes, turning occasionally, until tender when pierced with a fork.
- Sweet Potato Slices: Place directly on the grill grates, arranging them in a single layer. Grill for 3-5 minutes per side, until tender and slightly charred.
- Sweet Potato Cubes: Place in a grill basket or on skewers. Grill for 10-15 minutes, turning frequently, until tender and slightly charred.
- Serving:
- Remove from grill and let cool slightly before serving.
- Serve as a side dish, or use in salads, tacos, or other creative recipes.
Temperature Control: The Key to Perfect Grilling
Maintaining the correct grill temperature is paramount to prevent burning and ensure even cooking. Here’s a quick reference guide:
| Method | Temperature | Cooking Time |
|---|---|---|
| Whole | Medium (350-400°F) | 45-60 minutes |
| Slices | Medium (350-400°F) | 3-5 minutes per side |
| Cubes | Medium (350-400°F) | 10-15 minutes |

Frequently Asked Questions (FAQs)

While you can grill frozen sweet potatoes, the texture might be slightly different compared to fresh. Thaw them partially before grilling to ensure even cooking.
How do I prevent sweet potatoes from sticking to the grill?
