If you’ve ever been frustrated by soggy homemade sweet potato fries, these Crispy Baked Sweet Potato Wedges with Garlic Herb Aioli are here to transform your cooking forever: blistered, caramelized exterior ridges that shatter with a satisfying crunch, yielding to fluffy, naturally sweet molten centers, paired with a zesty scratch-made garlic herb dipping aioli. In just 35 minutes, this wholesome oven-baked finger food brings gastropub indulgence straight to your table with zero deep-frying mess.
Achieving true restaurant-level crunch on sweet potatoes requires mastering two essential culinary techniques: soaking sliced wedges in cold water to strip away excess exterior starch, and dusting the dried wedges in a light veil of cornstarch before oiling. The cornstarch absorbs remaining surface moisture and gelatinizes in the intense 425°F oven heat, forming a crackling micro-crust that seals in the creamy potato flesh.

Step-by-Step Cooking Walkthrough

3. High-Heat Bake: Spread on parchment-lined sheets without overcrowding. Bake at 425°F (220°C) for 25-30 minutes, flipping once.
4. Whisk Aioli & Serve: Whisk garlic aioli together, transfer piping hot crispy wedges to a platter, and serve immediately.
3 Chef Secrets for Perfect Results
1. Never Overcrowd the Pan: Trapped steam is the #1 enemy of crispiness! Use two baking sheets so every wedge has at least 1 inch of breathing room.
2. Dry Extremely Thoroughly: Moisture left on the potatoes creates steam pockets under the cornstarch. Take time to press dry with paper towels.
3. Salt Immediately After Baking: Sprinkling flaky sea salt onto the sizzling wedges right as they exit the oven ensures the crystals bond to the hot oil.
What to Serve With Crispy Sweet Potato Wedges
- Gourmet Halal Burgers: The ultimate companion alongside smash burgers, sliders, or grilled chicken sandwiches.
- Barbecue Platters: Pairs beautifully with smoked brisket, pulled beef, and honey glazed ribs.
- Game Day Appetizers: Serve alongside hot chicken wings, mozzarella sticks, and spinach dip.
Storage, Freezing & Reheating Instructions

- Air Fryer Reheating: Reheat in an air fryer at 380°F for 3 to 4 minutes to restore original blistered crunch (never microwave!).
- Oven Reheating: Bake on a hot baking sheet at 400°F for 6 to 8 minutes until sizzling.
Crispy Baked Sweet Potato Wedges with Garlic Herb Aioli
Ingredients
Method
- Preheat oven to 425°F (220°C). Line two large baking sheets with parchment paper or heavy-duty foil.
- Cut sweet potatoes into uniform 1/2-inch thick wedges. Soak in a bowl of cold water for 20 minutes to draw out excess surface starches, then pat thoroughly dry with paper towels.
- Place dried wedges into a large bowl. Dust evenly with cornstarch, tossing until lightly and evenly coated.
- Drizzle with extra virgin olive oil, then sprinkle with smoked paprika, garlic powder, chopped rosemary, salt, and black pepper. Toss vigorously until every wedge is glistening.
- Arrange sweet potato wedges on baking sheets in a single layer with ample space between each wedge (do not overcrowd, or they will steam instead of roast!).
- Bake at 425°F (220°C) for 25 to 30 minutes, flipping once at the 15-minute mark, until blistered, golden-brown, and audibly crisp.
- While wedges bake, whisk mayonnaise, grated garlic, fresh lemon juice, salt, and minced chives together to create the garlic herb aioli.
- Transfer hot wedges to a platter, sprinkle with flaky sea salt and fresh rosemary, and serve immediately with garlic aioli!
