Side Dishes
This sweet potato Blackstone recipe transforms humble sweet potatoes into restaurant-quality sides with caramelized edges and tender interiors—all achieved on a single griddle. The Blackstone’s even heat distribution ensures crispy char while keeping the centers perfectly soft, a technique I’ve perfected for outdoor cooking.
No flipping or fussing required—just slice, season, and let the griddle do the work.
The secret lies in preheating the Blackstone to medium-high heat and using a light oil to prevent sticking. Slice the sweet potatoes into even rounds (about ¼-inch thick) so they cook uniformly, and season generously with salt, pepper, and smoked paprika for depth.
A sprinkle of cinnamon or cayenne adds warmth or a kick, depending on your preference.
Once on the griddle, the sweet potatoes develop golden-brown grill marks and caramelized edges in just 3-4 minutes per side, releasing an intoxicating aroma that signals dinner is ready. The texture is crispy on the outside with a creamy, almost custard-like interior—a contrast that makes this side dish unforgettable.
Serve these charred beauties with a drizzle of melted butter, a drizzle of honey, or a sprinkle of flaky sea salt for extra flavor. They pair perfectly with grilled meats, blackened fish, or even as a standalone vegetarian main.
The Blackstone’s versatility makes this recipe ideal for backyard cookouts or weeknight dinners alike.
Ingredients for sweet potato blackstone
Nine essential ingredients transform simple sweet potatoes into Blackstone masterpieces with caramelized edges and tender centers.
| Ingredient | Amount | Notes |
|---|---|---|
| Large Sweet Potatoes 🍠 | 2 whole | Organic preferred, skin-on for texture |
| Avocado Oil 🫒 | 2 tbsp | High smoke point for griddle |
| Diamond Crystal Kosher Salt 🧂 | 1 ½ tsp | Coarse grain for even seasoning |
| Freshly Ground Black Pepper 🌶️ | ½ tsp | Cracked peppercorns preferred |
| Smoked Paprika 🌶️ | 1 tsp | Spanish smoked variety for depth |
| Ground Cinnamon 🍃 | ½ tsp | Ceylon preferred for delicate flavor |
| Cayenne Pepper 🔥 | ¼ tsp | Adjust for heat preference |
| Unsalted Butter 🧈 | 2 tbsp | Melted for post-cooking drizzle |
| Raw Honey 🍯 | 1 tbsp | Local honey for floral notes |
| Flaky Sea Salt 🧂 | 1 tsp | Maldon preferred for finishing |
The sweet potatoes are the foundation—organic, skin-on varieties like Beauregard develop the best caramelized crust. Whole Foods or local farmers markets carry the best quality, though any grocery store sweet potatoes work in a pinch. For even cooking, slice them into ¼-inch rounds using a mandoline or sharp knife. The smoked paprika is non-negotiable here; Penzeys brand delivers consistent depth of flavor. Preheat your Blackstone to medium-high (400°F)—this is critical for achieving that perfect char without burning.
No smoked paprika? Substitute with ½ tsp regular paprika plus ¼ tsp liquid smoke, though the flavor won't be identical. Short on cinnamon? Nutmeg at half the amount adds warmth without sweetness. The avocado oil should be lightly brushed (not drowned) on the griddle to prevent sticking—Trader Joe's brand works perfectly for this. For the finishing touches, Maldon flaky sea salt is ideal, but any high-quality sea salt will do. The butter and honey should be warmed to room temperature before drizzling to enhance their flavors.
Store any leftovers in an airtight container for up to 4 days—though honestly, these taste best fresh off the griddle. The sweet potatoes reheat beautifully in a 350°F oven for 10 minutes with a drizzle of water to restore moisture. For meal prep, slice and season the potatoes in advance, then store them in the fridge until ready to cook—this saves 30 minutes of prep time on busy weeknights. The griddle itself should be cleaned immediately after use with a stiff brush and hot water to remove any caramelized bits for next time.

Step-by-step instructions for sweet potato Blackstone masterpiece
Transform simple sweet potatoes into restaurant-quality charred perfection using just one pan.
Prep and Season the Sweet Potatoes
Begin by scrubbing the 2 whole large sweet potatoes thoroughly under cold water to remove any dirt. Using a sharp chef's knife, cut each potato lengthwise into 4 wedges, ensuring each wedge maintains its skin for texture. The skin should remain intact—this creates that beautiful charred exterior we're after.
In a small bowl, combine the 1.5 teaspoons Diamond Crystal kosher salt, 0.5 teaspoon freshly ground black pepper, 1 teaspoon smoked paprika, 0.5 teaspoon ground cinnamon, and 0.25 teaspoon cayenne pepper. Gently toss the sweet potato wedges in this spice blend until they're evenly coated. I like to press the spices into the flesh slightly so they adhere well during cooking. Let them sit at room temperature while you heat your Blackstone.
Heat the Blackstone and Cook Until Charred
Preheat your Blackstone griddle over medium-high heat until it's screaming hot—you should see a thin layer of smoke appear when you wipe a paper towel across the surface. Add the 2 tablespoons avocado oil and let it spread evenly across the surface, coating the entire griddle. The oil should shimmer but not smoke excessively.
Arrange the seasoned sweet potato wedges in a single layer on the griddle, leaving about ½ inch between each piece. Cook undisturbed for 8-10 minutes, until the edges develop deep char marks and the flesh begins to soften. You'll know they're ready when you see blackened edges with caramelized sweetness peeking through. Flip each wedge carefully using tongs, then cook another 6-8 minutes until both sides are beautifully charred and the flesh is tender when pierced with a fork.
Finish with Butter and Honey
Remove the sweet potatoes from the griddle and transfer them to a serving platter. In the same griddle, melt the 2 tablespoons unsalted butter over medium heat until it foams. Pour the melted butter evenly over the hot sweet potatoes, letting it drip into all the crevices. The residual heat will create a delicious sheen on the wedges.
Drizzle the 1 tablespoon raw honey evenly over the top, allowing it to pool in the natural indentations of the sweet potatoes. The heat from the griddle will cause the honey to caramelize slightly, adding another layer of sweetness. Finish with a generous sprinkle of the 1 teaspoon flaky sea salt, focusing on the top and edges where the char is most pronounced. The salt will enhance all the flavors and create a perfect balance of sweet, smoky, and savory notes.
Rest and Serve Immediately
Let the sweet potatoes rest for 2-3 minutes before serving. This brief resting period allows the juices to redistribute slightly, ensuring each bite remains moist and flavorful. The wedges should be tender enough to pierce easily with a fork but still hold their shape.
Serve immediately while still warm, as the contrast between the crispy charred exterior and tender interior is at its peak. The combination of smoky spices, caramelized honey, and buttery richness creates a dish that's both hearty and elegant—perfect for any meal. The Blackstone's cast iron surface ensures even heat distribution, giving you that professional-quality char every time.

Best sauces and condiments for this dish
Butter-Honey Classic
This timeless combo takes your Blackstone sweet potatoes to the next level. After cooking, melt 2 tbsp unsalted butter in the griddle and pour it generously over the hot wedges. The residual heat creates a luscious sheen while adding richness.
Immediately drizzle with 1 tbsp raw honey—the caramelization from the griddle enhances its floral notes beautifully. Finish with 1 tsp flaky sea salt to balance the sweetness and highlight the charred edges. 🍯
Spicy Maple-Glaze
For a bold twist, mix 2 tbsp pure maple syrup, 1 tsp cayenne pepper, and ½ tsp smoked paprika in a small saucepan. Simmer over medium heat for 2 minutes until slightly thickened.
Brush this glaze over the cooked sweet potatoes and return them to the griddle for 1-2 minutes to caramelize the sugars. The heat from the Blackstone intensifies the maple flavor while adding a smoky kick.
Tahini-Lemon Zing
Whisk together 2 tbsp tahini, 1 tbsp lemon juice, 1 tsp honey, and ½ tsp garlic powder until smooth. Drizzle this creamy sauce over the warm sweet potatoes and sprinkle with toasted sesame seeds.
The tahini adds a nutty depth that pairs perfectly with the smoky char, while the lemon brightens the dish. This works especially well for a Middle Eastern-inspired meal.
Brown Butter-Cinnamon
After cooking the sweet potatoes, melt 2 tbsp butter in the griddle until it turns golden brown and nutty. Stir in ½ tsp cinnamon and ¼ tsp cayenne for warmth. Pour this fragrant butter over the wedges and let it soak in.
The brown butter adds a complex, toasty flavor that complements the natural sweetness of the potatoes. This version feels especially cozy for fall gatherings.
Chimichurri Finish
For a fresh, herbaceous contrast, prepare a quick chimichurri by blending ¼ cup parsley, 2 tbsp olive oil, 1 tbsp red wine vinegar, 1 tsp red pepper flakes, and ½ tsp garlic powder.
Spoon this vibrant sauce over the warm sweet potatoes and sprinkle with crumbled feta cheese** for a tangy, herby finish. The acidity cuts through the richness of the charred potatoes beautifully.
Greek Yogurt-Dill
Mix ¼ cup Greek yogurt, 1 tbsp lemon juice, 1 tsp fresh dill, and a pinch of salt. Dollop this creamy sauce alongside the sweet potatoes or drizzle it over the top.
The cool, tangy yogurt balances the smoky, charred flavors while adding a refreshing contrast. This pairing works especially well with grilled meats like chicken or lamb.

Frequently asked questions
Can I use regular potatoes instead of sweet potatoes on the Blackstone?
While you can technically cook regular potatoes on a Blackstone, they won't achieve the same caramelized sweetness and texture. Sweet potatoes have a higher sugar content that creates beautiful charred edges and tender centers when grilled. For a similar effect, try Yukon Gold potatoes—but they'll still lack the natural sweetness and vibrant color of sweet potatoes.
How do I prevent the sweet potatoes from sticking to the Blackstone?
Preheat your Blackstone to medium-high heat (400°F) until it's screaming hot, then add 2 tablespoons of avocado oil and let it spread evenly. The key is to ensure the griddle is properly seasoned and the oil is hot enough to shimmer. Cook the potatoes undisturbed for the full time—don't flip too soon, as this helps create a natural release layer.
Can I make this recipe ahead of time?
You can prep the sweet potatoes up to 24 hours ahead by slicing and seasoning them, then storing them in an airtight container in the fridge. Cook them fresh on the Blackstone for the best texture, but you can reheat leftovers in a 350°F oven for 10 minutes with a splash of water to restore moisture. The charred edges won't be as crispy, though!
What's the best way to store leftover Blackstone sweet potatoes?
Store leftovers in an airtight container in the refrigerator for up to 4 days. For reheating, place them in a single layer on the Blackstone over medium heat for 3-4 minutes per side to restore some crispiness. Alternatively, reheat in a 350°F oven for 10 minutes with a drizzle of water or butter to maintain moisture.
Can I use this recipe on a regular grill instead of a Blackstone?
Yes, but you'll need to adjust the cooking time. A regular grill has hotter, more concentrated heat zones, so reduce the temperature to medium (350°F) and watch closely. You may need to cook the sweet potatoes for 5-7 minutes per side instead of 8-10 minutes. The Blackstone's flat surface and even heat distribution make it ideal for this recipe, though.
