How to Make Grilled Sweet Potatoes with Lemon-Dill Yogurt Sauce Recipe

Step 1: Prepare the Grill and Sweet Potatoes

Start by preheating your grill to medium-high heat because that’s what will give the sweet potatoes those gorgeous grill marks and slight smokiness we want. While the grill heats up, peel and cut the sweet potatoes into wedges that are about one and a half inches thick—this thickness is perfect for grilling without having them fall apart.

Step 2: Season and Grill the Sweet Potatoes

Place the wedges on a large rimmed baking sheet, then drizzle with olive oil and sprinkle with 1 teaspoon of kosher salt. Toss everything together so each piece is evenly coated with oil and salt, enhancing flavor while preventing sticking. Arrange the potatoes cut side down on the grill and let them cook, turning every 2 to 3 minutes until they’re fork tender and have a beautiful charred surface—this should take about 15 minutes. Each flip seals in flavor and texture perfectly.

Step 3: Blend the Lemon-Dill Yogurt Sauce

While the potatoes are grilling, it’s time to prepare the luscious lemon-dill yogurt sauce. In a blender or food processor, combine Greek yogurt, chopped green onions, fresh dill, smashed garlic cloves, fresh basil leaves, lemon juice, and the remaining ½ teaspoon of salt. Blend the mixture until it’s smooth and creamy, about 1 to 3 minutes. This sauce brings a bright, tangy contrast to the naturally sweet and smoky potatoes.

Step 4: Assemble and Serve

When the sweet potatoes are tender and charred to perfection, transfer them to a serving platter. Drizzle generously with the lemon-dill yogurt sauce and sprinkle extra fresh dill over the top. Serve this dish family style for an inviting presentation that encourages everyone to dig in and savor the vibrant flavors together.

Garnishes

Adding fresh herbs like extra dill or finely chopped basil on top elevates the dish visually and in flavor—herbaceous notes bring brightness and invite the eye to feast first. You can also sprinkle a little smoked paprika or a handful of toasted pine nuts to add a subtle smoky or crunchy contrast, perfectly complementing the grilled potatoes and creamy sauce.

Side Dishes

For a well-rounded meal, serve alongside some grilled vegetables or a crisp green salad with a citrus vinaigrette for contrast. The fresh, tangy elements in the lemon-dill yogurt sauce pair beautifully with grains like quinoa or couscous, making this dish fantastic as a vegetarian main or a colorful side dish.

Creative Ways to Present

Try layering the grilled sweet potato wedges in a shallow bowl and swirling the yogurt sauce around for a rustic yet elegant look. Alternatively, serve them on skewers with the yogurt sauce on the side for easy dipping—perfect for casual entertaining or picnics. The vibrant colors and fresh herbs make this dish visually inviting without extra fuss.

Make Ahead and Storage

Storing Leftovers

If you have any leftover grilled sweet potatoes with lemon-dill yogurt sauce recipe, place the potatoes and sauce separately in airtight containers. Store them in the refrigerator for up to 3 days. Keeping the sauce separate prevents the potatoes from becoming soggy, preserving their texture and flavor.

Freezing

While you can freeze grilled sweet potatoes on their own by wrapping them tightly and placing in a freezer-safe container, it’s best not to freeze the lemon-dill yogurt sauce as the texture changes after thawing. Instead, freeze only the potatoes and prepare a fresh batch of the sauce when ready to serve.

Reheating

To reheat, warm the sweet potatoes gently in a preheated oven at 350°F (175°C) for about 10 minutes or until heated through. Avoid microwaving if you want to maintain their firmness and grill marks. Add the yogurt sauce fresh from the fridge when serving for that vibrant lemon-herb lift.

FAQs

Can I use regular yogurt instead of Greek yogurt?

Yes, you can use regular yogurt, but Greek yogurt is thicker and creamier, which helps the sauce cling nicely to the sweet potatoes. If using regular yogurt, consider straining it to remove excess liquid.

What if I don’t have a grill available?

No grill? No problem! You can roast the sweet potatoes in the oven at 425°F (220°C) for about 25-30 minutes, turning halfway through, until tender and slightly caramelized.

Can I prepare the lemon-dill yogurt sauce in advance?

Absolutely! The sauce can be made up to 24 hours ahead and refrigerated. Just give it a good stir before serving to re-mix the flavors and consistency.

Is this recipe suitable for a vegan diet?

To make this recipe vegan, substitute the Greek yogurt with a plant-based yogurt alternative and ensure your oil and salt are plant-based friendly. The rest of the ingredients are naturally vegan.

How spicy is this dish? Can I add heat?

This dish is mild and fresh by nature, but if you love a little kick, sprinkle some red pepper flakes into the yogurt sauce or add a dash of hot sauce on top before serving.

There is something incredibly satisfying about the combination of smoky, tender grilled sweet potatoes paired with a bright, creamy lemon-dill yogurt sauce.
