Ingredients for this Grilled Sweet Potato Fries with Garlic Aioli
- 2 medium sweet potatoes, peeled and cut into fries
- 2 tablespoons olive oil
- 1 teaspoon paprika
- 1/2 teaspoon garlic powder
- 1/2 teaspoon salt, plus more to taste
- 1/4 teaspoon black pepper
- 1 clove garlic, minced (for aioli)
- 1/2 cup mayonnaise
- 1 tablespoon lemon juice
- Pinch of salt (for aioli)
- 1 tablespoon olive oil (for aioli, optional)
- 1 tablespoon water (to thin aioli, optional)
Instructions
- Wash and dry the sweet potatoes. Slice into evenly sized fries so they cook at the same pace. Aim for about 1/4 inch thick to balance a crisp edge with a fluffy center.
- In a bowl, toss the fries with olive oil, paprika, garlic powder, salt, and pepper. Make sure every piece gets a light coating so the spices cling as they grill.
- Preheat your grill to medium-high. If you’re using charcoal, let the fire settle to a steady heat with a good layer of white ash. For gas grills, aim for about 375–425°F (190–220°C).
- Grill the fries in a single layer, turning once, until the edges are crisp and the centers are tender. This usually takes around 4–5 minutes per side. Don’t crowd the grill; work in batches if needed.
- While the fries cook, whisk together the aioli ingredients: mayonnaise, minced garlic, lemon juice, and a pinch of salt. If you prefer a thinner dip, whisk in a bit of water or olive oil until you reach the desired consistency.
- Taste and finish: a touch more salt can bring out the flavors. Serve the hot fries with the garlic aioli on the side for dipping.
- Optional: finish with a squeeze of lemon over the fries and a sprinkle of chopped herbs for color and brightness.

Nutritional information
Estimated per serving: calories about 320. This can vary with the exact size of potatoes and how thickly you cut them, or how generous you are with the aioli. If you’re watching portions, remember that the aioli adds fat and calories, so you can dip more conservatively or thin the aioli with a little water to stretch it further.
Frequently asked questions
Can I bake these fries instead of grilling?
Yes. Preheat the oven to 425°F (220°C). Toss the fries with oil and spices, lay them in a single layer on a parchment-lined sheet, and bake for 20–25 minutes, flipping halfway through, until crisp and golden. A brief broil at the end can help them crisp up more if you like.
What if I don’t have a grill?
You can use a grill pan on the stovetop or simply roast the fries in the oven as described above. Both methods will still give you that nice char and a satisfying texture, with the aioli ready to dip.
How long does the aioli stay fresh?
Garlic aioli will stay fresh for up to 3 days in a sealed container in the refrigerator. Keep it separate from the fries, and re-whisk a little before serving. If you’re concerned about raw garlic taste lingering, you can blend in a touch of extra lemon juice to brighten it up when you re-use.
Grilled Sweet Potato Fries with Garlic Aioli
Ingredients
- 2 medium sweet potatoes, peeled and cut into fries
- 2 tablespoons olive oil
- 1 teaspoon paprika
- 1/2 teaspoon garlic powder
- 1/2 teaspoon salt, plus more to taste
- 1/4 teaspoon black pepper
- 1 clove garlic, minced (for aioli)
- 1/2 cup mayonnaise
- 1 tablespoon lemon juice
- 1 pinch salt (to taste)
- 1 tablespoon olive oil (for aioli, optional to loosen)
- 1 tablespoon water (to thin aioli, optional)
Instructions
- Wash and dry the sweet potatoes. Slice them into evenly sized fries so they cook at the same pace. Try to keep them about 1/4 inch thick for a good balance of crisp edges and fluffy centers.
- In a bowl, toss the fries with olive oil, paprika, garlic powder, salt, and pepper. Give them a quick mix to coat every piece. If you like a little extra heat, a pinch of chili flakes can be added here.
- Preheat your grill to medium-high. If you’re using a charcoal grill, let the coals burn down to a steady heat with a nice layer of white ash behind them. If you’re using a gas grill, set it to about 375–425°F (190–220°C).
- Place the fries directly on the grill grates in a single layer, trying not to crowd them. Grill for about 4–5 minutes per side, flipping once, until the edges are crisp and the centers are tender. If some pieces are cooking faster, move them to the cooler side of the grill to prevent burning.
- While the fries grill, make the garlic aioli. In a small bowl, whisk together the mayonnaise, minced garlic, lemon juice, and a pinch of salt. If you want a thinner sauce for dipping, whisk in a little water or olive oil until it reaches your desired consistency.
- Taste the fries as they come off the grill. If they need a touch more salt, sprinkle it over while they’re hot so it sticks. Serve the hot fries immediately with the garlic aioli on the side.
- Optional finishing touch: a squeeze of extra lemon over the fries and a sprinkle of chopped parsley or chives for color. This brightens the dish and adds a fresh note that complements the smoky sweetness of the potatoes.
