Crispy, smoky, and with just enough spice to keep things lively, these Blackstone Sweet Potatoes are the side dish that disappears before anything else on the table. They get a quick head start with 10 minutes in the microwave, then move to the hot griddle where cumin, smoked paprika, and pickled jalapeños bring them to life. The result? Sweet and smoky sweet potatoes with golden, crunchy edges, soft centers, and layers of bold flavor.
At my house, griddled sweet potatoes have become a regular in the rotation. The Blackstone creates the perfect char for a crispy sweet potato hash, but the griddle's only half the story.
Cumin warms everything from the inside, smoked paprika builds that deep, just-this-side-of-charred flavor without anything actually burning, and pickled jalapeños at the finish deliver the brine-y acid you need to cut sweet potato's natural sweetness (otherwise you're one yam casserole away from Thanksgiving, and that's not what we're doing here).
When I tested this recipe, the combination of smoky edges and tangy jalapeños made it an instant keeper. It is one of those easy griddle side dishes you can pair with just about anything.
I love it with Blackstone Broccoli, Roasted Grape Tomatoes, and Marinated Skirt Steak on the Blackstone.
Griddle Sweet Potatoes Ingredients and Substitutions
- Sweet potatoes: Any variety works, but orange-fleshed is most common. White sweet potatoes are less sweet and hold their shape well.
- Ground cumin: Substitute ground coriander or chili powder for a different twist.
- Smoked paprika: Use hot smoked paprika for more heat or regular paprika for a milder flavor.
- Avocado oil: You can swap it with grapeseed oil, refined coconut oil, or regular olive oil. Butter could also be used, but I recommend mixing it with a little oil to raise the smoke point.
- Pickled jalapeños: Found in the Mexican or pickle aisle; swap with fresh jalapeños or pickled banana peppers for a milder kick.

Wendy's Tips & Tricks for Griddled Sweet Potatoes
- Other ways to serve – Try them as griddle breakfast potatoes with eggs, toss them in salads, or pair with other cast iron griddle vegetables for a colorful spread. This method works for sweet potato fries, wedges, or even hearty sweet potato hash.
- Go small - To ensure your potatoes cook through, make sure that you cut them into ½" cubes.
- Skip the Sticking – Keep the surface hot, well-oiled, and clean. High-heat oils like avocado are perfect for flat-top sweet potato recipes.
- Mix up the flavors – I love these smoky Blackstone sweet potatoes, but sweet potatoes lend themselves to a little creativity. Try cajun spice for a crispy sweet potato hash, curry, or rosemary and garlic. I kept things savory, but feel free to make it sweet with some brown sugar or maple syrup. (Just remember to watch the heat if you add sugar to the griddle - it burns quickly.)

If you are not able to microwave the potatoes at campsite, can you boil the potatoes instead?
