Ingredients & Why They Work
Each ingredient here plays a key role to bring out the best textures and flavors—sweet potatoes are hearty and hold up well to the grill, while fresh herbs and lemon juice brighten the garlic aioli perfectly. When shopping, look for firm, unblemished sweet potatoes and fresh garlic for the best results.
- Sweet potatoes: The star of the show—look for firm, large sweet potatoes for even cooking and plenty of wedges.
- Olive oil: Helps the potatoes get that caramelized, crispy edge on the grill.
- Fresh thyme (optional): Adds a subtle herbaceous note that pairs beautifully with the sweetness.
- Sea salt and ground pepper: Basic seasoning that brings out the natural sweetness and balances flavors.
- Greek yogurt and mayonnaise: Base for the aioli to keep it creamy with a slight tang.
- Lemon juice: Brightens the aioli and cuts through richness wonderfully.
- Garlic: The punchy flavor in the aioli that makes it irresistibly savory.
- Fresh parsley (optional): Lovely garnish for a pop of color and freshness.
Make It Your Way
I love playing around with this recipe — adjusting the herbs, switching up the aioli flavor, or even adding a smoky paprika kick to the oil. Don’t hesitate to make it your own and tailor it to whatever season or mood you’re in.
- Variation: Once, I swapped the thyme for rosemary, and it added such a lovely woodsy aroma that I still recommend trying at least once.
- Spice it up: Add a pinch of cayenne to the aioli if you want a subtle heat that wakes up your taste buds.
- Make it vegan: Use plant-based mayo and dairy-free yogurt to keep all the creamy garlic goodness without any dairy.
- Seasonal twist: Toss in some chopped fresh rosemary or a sprinkle of smoked paprika for autumn vibes.
Step-by-Step: How I Make Grilled Sweet Potatoes with Garlic Aioli Recipe
Step 1: Parboil the Sweet Potatoes for Tenderness
Start by placing your scrubbed sweet potatoes in a large pot filled with salted cold water—this helps season them evenly. Bring to a boil, then simmer for about 10 minutes. You’re aiming for that sweet spot where a sharp knife meets just a little resistance, so the potatoes won’t fall apart on the grill but cook through nicely. Trust me, this step makes grilling so much easier.
Step 2: Slice and Season with Herb-Infused Oil
After draining and cooling your potatoes enough to handle, cut them in half lengthwise, then slice into wedges—this makes for perfect grill-ready pieces. Mix olive oil with chopped thyme (if you’re using it), salt, and pepper, then brush generously on each wedge. Don’t skimp here; that oil locks in moisture and creates those irresistible crispy edges when grilling.
Step 3: Grill Until Perfectly Charred
Heat your grill to medium-high and give the rack a light oiling to prevent sticking. Lay down your wedges and cook for 7 to 8 minutes, flipping once halfway through. You’ll want to see grill marks form and be able to easily pierce the wedges with a fork. Keep an eye out — sweet potatoes can go from perfect to mushy if left too long!
Step 4: Whip Up the Garlic Aioli and Serve
While the potatoes grill, mix Greek yogurt, mayo, freshly squeezed lemon juice, minced garlic, and a pinch of salt and pepper until smooth. This garlic aioli is refreshing but rich with that garlic punch, which perfectly complements the sweetness of the potatoes. Serve the grilled wedges warm with a generous dollop of aioli and a sprinkle of fresh parsley, if you like.
Top Tip
From many rounds of grilling these sweet potatoes, I’ve learned that the parboiling step really makes or breaks the texture. Here’s what helped me every time:
- Perfect Parboil Timing: Don't overcook them in the water—aim for just tender, not soft. They’ll finish cooking on the grill and keep their shape better.
- Oil Generously: Brushing oil with herbs ensures a crispy crust and adds depth. I like to double-brush halfway through grilling for extra flavor.
- Aioli Freshness: Make the garlic aioli a little ahead of time to let the flavors meld, but add the lemon juice last to keep it bright.
- Don’t Crowd the Grill: Give your wedges space so the grill heat circulates evenly—this creates those gorgeous char lines and avoids steaming.
How to Serve Grilled Sweet Potatoes with Garlic Aioli Recipe
Garnishes
I like topping my grilled sweet potato wedges with a scattering of fresh parsley or even chopped chives—something green and fresh to brighten up the plate. A little lemon zest over the aioli adds an unexpected punch too.
Side Dishes
This recipe pairs beautifully with grilled chicken or a fresh, crunchy kale salad for a balanced meal. I’ve also served it alongside burgers and veggie wraps for a fun weekend cookout vibe.
Creative Ways to Present
For a party, I like layering these wedges in a rustic wooden board with small bowls of the garlic aioli and even some spicy ketchup. It makes a colorful, shareable dish that's both casual and inviting. You could also skewer wedges for easy finger food at gatherings.
Make Ahead and Storage
Storing Leftovers
Leftover grilled sweet potatoes keep well in an airtight container in the fridge for up to 3 days. I always store the aioli separately to keep it fresh and creamy.
Freezing
While you can freeze the grilled wedges, I find the texture changes slightly on thawing—so I prefer making fresh portions of the aioli and grilling new potatoes when I want that fresh grilled flavor. But if you freeze, flash freeze the wedges separately first, then bag.
Reheating
To reheat, pop the wedges under a broiler or in a hot oven for a few minutes to restore crispiness. Avoid the microwave because it tends to make them mushy. Serve with freshly made or chilled garlic aioli for best results.
Frequently Asked Questions:
You certainly can, but parboiling ensures the sweet potatoes cook through evenly without burning the outside. It’s a little extra step that pays off with tender, fully cooked wedges.
Greek yogurt alone can serve as a lighter base, or you can use vegan mayonnaise for a dairy-free option. The key is to maintain a creamy texture that balances the garlic and lemon flavors.
Absolutely! You can use a grill pan on your stovetop or roast the sweet potato wedges in a hot oven at around 425°F (220°C) until caramelized and tender. The aioli dip remains the same and is just as delicious.
You can prepare the garlic aioli up to 2 days in advance and keep it covered in the fridge. Add the lemon juice right before serving if you want the brightest lemon flavor, but mixing it in early still tastes great.
Final Thoughts
I genuinely love this Grilled Sweet Potatoes with Garlic Aioli Recipe because it’s simple enough for everyday meals but impressive enough for guests. The balance of smoky, sweet, and tangy keeps me coming back again and again—and I hope you’ll feel the same. Give it a try next time you fire up the grill or want a refreshing but comforting side!

Description
This Grilled Sweet Potatoes recipe offers a delicious and healthy way to enjoy tender, smoky sweet potatoes paired with a creamy garlic aioli dipping sauce. Perfect as a side dish or snack, the sweet potatoes are parboiled, seasoned with olive oil and herbs, then grilled to perfection with beautiful grill marks.

Sweet Potatoes
- 3 large sweet potatoes, scrubbed well

- 1 tablespoon fresh thyme, chopped (optional)
- ½ teaspoon sea salt

- ¼ cup mayonnaise
- Juice from one lemon (2-3 tablespoons)
- 1 clove garlic, minced

Instructions
- Parboil the Potatoes: Place the sweet potatoes in a large pot and cover with cold salted water. Bring to a boil and simmer until slightly resistant when pierced with a sharp knife or fork, about 10 minutes depending on the size of the potatoes. Drain well and allow to cool.

- Grill the Potatoes: Preheat the grill to medium-high heat and lightly oil the grill rack. Place the seasoned sweet potato wedges on the grill and cook until grill marks appear and the potatoes are tender throughout, about 7 to 8 minutes, flipping them once halfway through cooking.

Notes
- Use firm, medium to large sweet potatoes for even cooking and ease of slicing.
- Parboiling the potatoes before grilling ensures they cook through without burning on the grill.
- Fresh thyme adds a nice herbal note but can be omitted or replaced with rosemary or oregano.
- For a dairy-free aioli, substitute Greek yogurt with an equal amount of vegan yogurt or additional mayonnaise.
- Brush the grill grates with oil to prevent the sweet potatoes from sticking.
- Leftovers can be reheated in a skillet or oven to restore the grilled texture.
