Introduction

There is a distinct kind of magic that happens when the natural sugars of a sweet potato meet the searing heat of an open fire. I can still vividly recal the aroma of my first real backyard cookout of the season—wood smoke mingling with the scent of caramelizing sugar. This isn't just a side dish; it is a mood setter. The high heat of the grill creates a crispy, charred skin that gives way to a tender, buttery interior, reminding me of cozy autumn evenings spent around a crackling bonfire.

Why This Recipe is a Keeper

I absolutely adore this recipe because it captures the heart of Midwestern barbecue: bold, smoky, and unapologetically rich. By finishing the potatoes with a classic, molasses-heavy Kansas BBQ sauce, you add a layer of sticky, tangy sweetness that complements the earthiness of the potato perfectly. It is a crowd-pleaser that bridges the gap between comfort food and gourmet grilling with minimal fuss.

Kitchen Wisdom

  • Manage Your Zones: The Arteflame cooktop has various heat zones. Start the sear near the center for color, then move the wedges toward the outer edge to finish roasting gently so the outside doesn't scorch before the inside is fluffy.
  • Keep the Skin: Don't peel them! The skin holds the wedge together on the flat top and crisps up beautifully, adding a delightful textural contrast to the soft flesh inside.

Swaps & Substitutions

If you need to keep this dairy-free, simply use olive oil instead of butter in the marinade. For a twist on the flavor, swap the Kansas sauce for a spicy chipotle glaze if you prefer heat over molasses sweetness.

Ingredients

The Produce

  • 4 large sweet potatoes, scrubbed clean and dried
  • 2 tablespoons fresh parsley, chopped (for garnish)

The Marinade & Glaze

  • 1/4 cup olive oil (or melted butter for richness)
  • 1 cup Kansas-style BBQ sauce (thick, tomato-based with molasses)
  • 1 teaspoon smoked paprika
  • 1 teaspoon garlic powder
  • 1/2 teaspoon onion powder
  • 1 teaspoon sea salt
  • 1/2 teaspoon black pepper

Instructions

Step 1: Prepare the Potatoes

  1. Wash the sweet potatoes thoroughly to remove any dirt from the skin.
  2. Slice the potatoes lengthwise into generous wedges. Aim for about 8 wedges per potato to ensure they are substantial enough to hold up to the heat without falling apart.
  3. In a large mixing bowl, toss the wedges with the olive oil, smoked paprika, garlic powder, onion powder, salt, and black pepper until they are evenly coated.

Step 2: Fire Up the Arteflame

  1. Build a fire in the center of your Arteflame grill. Let it burn down until you have a solid bed of coals and the cooktop is searing hot.
  2. Lightly oil the flat steel cooktop to prevent sticking, using a paper towel dipped in vegetable oil or a dedicated seasoning puck.

Step 3: The Initial Sear

  1. Place the sweet potato wedges directly onto the flat cooktop. For the best texture, place them on the medium-heat zone (not directly next to the open flame, but not on the far edge).
  2. Grill the potatoes for about 8 to 10 minutes on one side. You are looking for a deep, golden-brown crust to form. Do not move them too early, or you will lose that essential char.

Step 4: Flip and Tenderize

  1. Flip the wedges over using tongs. They should release easily from the cooktop if they are properly seared.
  2. Continue cooking for another 8 to 10 minutes. Test for doneness by piercing the thickest part of a wedge with a fork; it should slide in with little resistance.

Step 5: Glaze and Serve

  1. During the last 2 minutes of cooking, brush the Kansas-style BBQ sauce generously over the wedges. Because Kansas sauce is high in sugar, you want to do this at the very end to caramelize the sauce without burning it.
  2. Remove the potatoes from the grill once the sauce is sticky and bubbly.
  3. Arrange on a platter and garnish with fresh chopped parsley before serving immediately.

Tips

Mastering sweet potatoes on the grill requires a bit of patience and heat management. The most common mistake is using heat that is too high, which scorches the outside before the inside is fluffy and cooked through. Utilize the different heat zones of the Arteflame cooktop; start the sear closer to the center for color, then move the wedges toward the outer edge to finish roasting gently if the outside is getting too dark. If you are short on time, you can par-boil the whole sweet potatoes for about 10 minutes before slicing and grilling; this cuts the grilling time in half. Furthermore, leave the skins on! The skin holds the wedge together and crisps up beautifully, adding a nutritional boost and a delightful textural contrast to the soft flesh inside. Always apply the BBQ sauce at the very end, as the sugar content in Kansas-style sauce burns rapidly.

Variations

While the classic Kansas profile is a crowd-pleaser, sweet potatoes are an incredibly versatile canvas for flavor experimentation. Depending on your main course, you can easily pivot the flavor profile of this side dish to match the theme of your cookout. Here are a few ways to mix things up while still using the same grilling technique:

  • Spicy Kick: Mix a teaspoon of cayenne pepper or chipotle powder into the dry rub and finish with a spicy BBQ sauce.
  • Savory Herb: Skip the BBQ sauce entirely and toss the grilled wedges in melted butter, fresh rosemary, and thyme.
  • Maple-Bourbon: Glaze the potatoes with a mixture of maple syrup and a splash of bourbon instead of BBQ sauce for a dessert-like sweetness.
  • Zesty Lime: Finish the grilled potatoes with a squeeze of fresh lime juice and cilantro instead of parsley to cut through the richness.
  • Bacon Crumbled: Sprinkle crispy fried bacon bits over the glazed potatoes just before serving for a salty crunch.

Best pairings

Kansas-Style Grilled BBQ Sweet Potatoes are bold enough to stand on their own, but they truly shine when paired with proteins that can match their intensity. The sweetness of the potato and the molasses in the sauce act as a perfect counterpoint to salty, savory, and fatty meats. This balance is crucial in BBQ, where palate fatigue can set in if everything is just one note of smoky flavor.

  • Smoked Pork Ribs: The classic pairing. The tender pork and the sweet potato texture are a match made in heaven.
  • Grilled Ribeye Steak: The earthy sweetness of the potato contrasts beautifully with the rich umami of a steak seared on the Arteflame.
  • Black Bean Burgers: For a vegetarian option, the hearty texture of a black bean burger holds up well against the BBQ glaze.
  • Coleslaw: A vinegar-based coleslaw provides a necessary acidic crunch to cut through the heavy sweetness of the potatoes.

Grilling sweet potatoes on an Arteflame is more than just a method of cooking; it is an experience that connects you to the primal joy of open-fire cuisine. This Kansas-Style recipe elevates a standard pantry staple into a memorable side dish that often steals the show from the main course.

So, the next time you fire up the grill, skip the aluminum foil packets and throw your sweet potatoes directly on the steel—your tastebuds will thank you for the crispy, caramelized difference.
