This combination mimics the quick frying process, giving you superior results with a healthier profile.
Essential Ingredients for Irresistible Sweet Potato Wedges and Aioli
Crafting these delectable Crispy Sweet Potato Wedges is surprisingly simple, especially when you begin with a selection of fresh, high-quality ingredients. A thoughtfully chosen blend of pantry spices and a vibrant, creamy dip bring everything together, resulting in a side dish that’s bold, deeply flavorful, and seriously addictive. Each component plays a crucial role in achieving the perfect texture and taste.
- **Sweet Potatoes:** The undisputed star of our recipe. Choose firm, unblemished sweet potatoes. Cutting them into thick, uniform wedges is key, as it allows them to caramelize beautifully on the outside while maintaining a tender, soft interior during baking. Their natural sweetness intensifies with roasting, providing a wonderful contrast to the savory seasonings.
- **Cornstarch:** This is our secret weapon for achieving an exceptional crunch without deep frying. A light coating of cornstarch absorbs surface moisture and creates a delicate, crispy shell around each wedge when baked at high temperatures. It’s a game-changer for oven-baked fries and wedges.
- **Olive Oil:** A good quality olive oil is essential for helping the spices adhere to the wedges, promoting even browning, and contributing to that rich, satisfying flavor. It’s also key to achieving crispiness by conducting heat effectively.
- **Paprika and Garlic Powder:** This dynamic seasoning duo provides a smoky depth and a savory kick that complements the sweet potatoes perfectly. Paprika adds a lovely color and subtle earthiness, while garlic powder infuses a comforting, aromatic flavor throughout the wedges.
- **Onion Powder:** Works synergistically with garlic powder to build a robust savory foundation for the seasoning blend, enhancing the overall flavor profile.
- **Cayenne Pepper & Red Chilli Powder (Optional):** For those who love a little heat, a pinch of cayenne or red chili powder introduces a warming spice that beautifully balances the sweetness of the potatoes. Adjust according to your preferred level of spiciness.
- **Dried Thyme:** Adds a fragrant, herbaceous note that rounds out the savory spices and elevates the overall aroma of the wedges.
- **Sea Salt:** Essential for enhancing all the flavors. We add it after baking to prevent it from drawing out moisture prematurely, which could hinder crispiness.
- **Avocado (for Aioli):** A perfectly ripe avocado is blended into a smooth, creamy garlic aioli. It provides a luxurious texture and healthy fats, creating the ultimate cool, refreshing dip for dunking each crispy wedge. Look for avocados that yield slightly to gentle pressure.
- **Whole Egg Mayonnaise:** Forms the rich, tangy base of our aioli, contributing to its classic texture and emulsified creaminess. High-quality mayonnaise makes a noticeable difference.
- **Fresh Garlic (for Aioli):** Minced garlic provides a pungent, aromatic punch that defines the aioli, giving it a vibrant and addictive flavor.
- **Lemon Juice (for Aioli):** Freshly squeezed lemon juice is crucial for brightening the aioli’s flavors, adding a zesty tang, and preventing the avocado from oxidizing and turning brown.

Step-by-Step Guide to Baking Crispy Sweet Potato Wedges
Achieving truly crispy sweet potato wedges at home is simpler than you might think, thanks to these easy-to-follow steps. Precision and a few clever tricks are all it takes to transform humble sweet potatoes into a golden, crunchy delight.
- **Soak the Potatoes for Optimal Crispiness:** Begin by placing your freshly cut sweet potato wedges in a large bowl and completely covering them with cold water. Allow them to soak for approximately one hour. This crucial step helps to draw out and remove excess starch from the potatoes, which is key to preventing them from becoming gummy and ensuring they bake up incredibly crispy. Don’t skip this for the best results!
- **Preheat Oven and Baking Sheets for Instant Sizzle:** Set your oven to a high temperature of 450°F (230°C). While the oven preheats, lightly grease two large baking sheets with olive oil or cooking spray. Crucially, place these greased trays into the oven while it preheats. This ensures the trays are scorching hot when the wedges go on, creating an immediate crisping effect similar to flash-frying, which prevents steaming and promotes maximum crunch.
- **Thoroughly Dry the Wedges:** Once soaked, drain the sweet potatoes completely. Then, using clean paper towels, pat them thoroughly dry. This step is incredibly important! Any residual moisture will steam the potatoes instead of crisping them. The drier they are, the crispier your final wedges will be.
- **Coat with Cornstarch for an Extra Crunch:** Transfer the dried sweet potato wedges into a large zip-lock bag. Add the cornstarch, then seal the bag, leaving some air inside. Shake vigorously for about 30 seconds until all the wedges are evenly coated in a fine layer of cornstarch. This creates that magical, thin, crispy layer that sets these wedges apart.
- **Season the Wedges to Perfection:** Gently transfer the cornstarch-coated wedges to a large mixing bowl, shaking off any significant excess starch. Drizzle generously with olive oil, then add your chosen seasoning mix (paprika, garlic powder, onion powder, cayenne pepper, red chili powder, and dried thyme). Toss everything thoroughly to ensure each wedge is beautifully and evenly coated with oil and spices. Remember, we’ll add salt later to avoid drawing out moisture during baking.
- **Arrange on Trays for Maximum Airflow:** Carefully remove the piping hot baking sheets from the oven. Working quickly, spread the seasoned wedges in a single layer across the trays. This is another crucial step for crispiness: ensure there’s at least ½ inch (1 cm) of space between each wedge. Overcrowding the trays will cause the wedges to steam rather than roast, resulting in a less crispy texture. Use two trays if necessary!
- **Bake Until Golden and Tender-Crisp:** Place the trays in the preheated oven. Bake for an initial 15–20 minutes. Then, remove the trays, carefully flip each wedge to ensure even cooking and browning, and return them to the oven for an additional 5–10 minutes, or until they are beautifully golden brown, wonderfully crispy, and tender when pierced with a fork. For extra crispiness, turn off the oven and leave the door ajar for 5 minutes before serving.
- **Prepare the Garlic Avocado Aioli and Serve:** While the wedges finish baking, prepare your aioli. Simply combine the ripe avocado, whole egg mayonnaise, minced garlic, and fresh lemon juice in a small food processor or a magic bullet. Blend until the mixture is completely smooth and creamy. Season with sea salt to taste. Once the wedges are out of the oven, sprinkle them with a generous amount of sea salt and serve immediately with the irresistible avocado garlic dip.
These incredibly flavorful and crispy Sweet Potato Wedges are incredibly versatile and pair beautifully with a wide array of main courses. For a comforting and hearty meal, serve them alongside a classic Beef and Pumpkin Shepherd’s Pie, where their sweetness provides a lovely contrast. To lighten things up, they make an excellent accompaniment to a zesty Grilled Chili Lime Chicken Fajita Salad, adding a satisfying crunch. For a cozy, warming option, pair them with a bowl of creamy, wholesome Creamy Pumpkin and Spinach Soup with Crispy Bacon. They also shine as a side to grilled fish, juicy burgers, or even as a standalone appetizer with an assortment of your favorite dipping sauces for a game day spread.
Recipe Frequently Asked Questions
The key to oven crispiness lies in several techniques: first, soaking the cut wedges in cold water helps remove excess starch. Second, thoroughly patting them dry before coating with cornstarch creates a thin, crispy crust. Finally, baking on preheated baking sheets at a high temperature ensures they “fry” rather than steam, giving you that perfect crunch without deep frying.
Absolutely! Leaving the skin on sweet potato wedges is a great choice. The skin adds a wonderful rustic texture, a slight chewiness, and an extra boost of fiber and nutrients. Just be sure to scrub the sweet potatoes exceptionally well under running water before cutting them into wedges.
Not necessarily. Sweet potatoes can cook in a similar timeframe to regular potatoes, often around 25–30 minutes at a high heat of 450°F (230°C). However, the exact cooking time can vary based on the thickness of your wedges and the efficiency of your oven. Sweet potatoes also tend to caramelize more due to their higher sugar content, which contributes to their delicious flavor.

Crispy Sweet Potato Wedges with Garlic Avocado Aioli
Ingredients
SWEET POTATO WEDGES:
- 2 large sweet potatoes scrubbed and cut lengthwise into wedges
- 1-2 tablespoons corn starch or cornflour
- 2 tablespoon olive oil
SEASONING:
- 2 teaspoons sweet paprika
- 2 teaspoons garlic powder
- 1/2 teaspoon onion powder
- 1/4 teaspoon cayenne pepper
- 1/2 teaspoon red chilli powder optional
- 2 teaspoons dried thyme
- 1 pinch sea salt to taste
AVOCADO GARLIC AIOLI:
- 1 large avocado
- 2 tablespoons whole egg mayonnaise
- 1 clove garlic minced
- 2 teaspoons lemon juice fresh squeezed
- 1 pinch sea salt to taste
Instructions
SWEET POTATO WEDGES:
-
To prepare your oven for optimal crisping, arrange your oven racks to the upper-middle position. This ensures the sweet potatoes get direct heat for browning.
-
Place the prepared sweet potato wedges in a large bowl and completely cover them with cold water. Let them soak for just over 1 hour. This crucial step extracts excess starch, which is vital for achieving that desirable crispy texture.
-
When you are ready to bake, preheat your oven to a high temperature of 450°F (230°C). Lightly grease 2 large baking sheets with nonstick cooking oil spray or brush them evenly with olive oil. Place these empty baking sheets into the preheating oven to get them scorching hot. This will provide an instant sear when the wedges are added, promoting crispiness.
-
After soaking, drain the sweet potato wedges thoroughly. Then, using a generous amount of paper towels, pat them as dry as you possibly can. Removing as much moisture as possible is absolutely essential for achieving a truly crispy result; residual water leads to steaming, not crisping.
-
Spoon the cornstarch into a large zip-lock (or sturdy plastic) bag. Add the dried sweet potato wedges into the bag. Seal the bag, ensuring there’s some air trapped inside, and shake it vigorously for about 30 seconds until the wedges are evenly coated with a thin layer of cornstarch. This forms the basis of our crispy crust.
-
Using tongs, transfer the coated wedges into a large clean bowl, gently shaking off any significant excess starch. Drizzle the wedges with the olive oil and sprinkle with your chosen seasoning mix (paprika, garlic powder, onion powder, cayenne pepper, red chili powder, dried thyme). Toss everything together very well to ensure each wedge is perfectly and evenly coated. **DO NOT ADD SALT at this stage**, as it can draw out moisture prematurely.
-
Carefully remove the pre-heated oven trays from the oven (they will be very hot!). Quickly arrange the seasoned wedges in a single layer on the trays, ensuring there is plenty of space between each one (at least 1/2-inch or 1cm gaps). This prevents them from steaming and promotes maximum airflow for crisping. You may need both trays.
-
Bake for 15-20 minutes. After this time, remove the trays from the oven and test a wedge with a fork to ensure it is *just* tender. Carefully flip all the wedges to expose the other side, again ensuring they are in a single layer with good spacing. Return the wedges to the oven and bake for a further 5-10 minutes, or until they are beautifully golden brown, wonderfully crisp, and tender through the middle.
-
For an extra crisp finish, turn the oven heat off but leave the oven door slightly ajar. Allow the wedges to sit in the cooling oven for about 5 minutes extra. This helps them dry out further and become even crispier. While they cool slightly, prepare your delightful Avocado Aioli dip.
AVOCADO AIOLI:
-
Combine the ripe avocado, whole egg mayonnaise, minced garlic, and fresh lemon juice in a magic bullet small cup or a small food processor. Blend for about 20 seconds, or until the mixture is perfectly smooth and creamy with no lumps. If needed, scrape down the sides with a spoon and blend for another 10 seconds. Season generously with sea salt to your taste, adjusting as necessary.
Once the wedges are ready, sprinkle them with a generous final pinch of sea salt and serve immediately with the freshly made Avocado Garlic Aioli for an unforgettable experience.
Chef’s Tips and Tricks
- **Spacing is Key:** To ensure your sweet potato wedges cook evenly and get truly crispy, it is absolutely critical to arrange them in a single layer on your baking trays, leaving at least 1cm (about ½ inch) of space between each piece. Overcrowding the tray will trap moisture, causing the wedges to steam rather than crisp. If you have too many wedges, use a third baking sheet or bake in batches.
- **Don’t Skip the Soak:** The soaking step is a non-negotiable for superior crunch! It effectively removes excess surface starch, which is responsible for that gummy texture and prevents proper crisping. This simple step makes a world of difference.
- **Pat Dry, Then Pat Again:** After soaking, drying the wedges thoroughly with paper towels is equally important. Any residual moisture will fight against the crisping process. The drier they are when they hit the cornstarch and oil, the crispier they’ll be.
- **Seasoning Timing:** Remember to add salt *after* baking. Salting the potatoes too early can draw out moisture, hindering the crisping process. A final sprinkle of sea salt after baking enhances all the flavors beautifully.
- **Aioli Variations:** Feel free to customize your Garlic Avocado Aioli! For an extra creamy kick, you can add a small dash of Dijon mustard. For a hint of smoky flavor, a pinch of smoked paprika can be a wonderful addition. If you desire more heat, a tiny drop of sriracha or a few extra flakes of red pepper will do the trick.
- **Storage and Reheating:** Leftover sweet potato wedges are best stored in an airtight container in the refrigerator for up to 3-4 days. To reheat and retain crispiness, spread them on a baking sheet and bake at 375°F (190°C) for 10-15 minutes, or reheat in an air fryer until hot and crispy. The aioli can be stored separately in an airtight container for 2-3 days in the refrigerator, but it’s best enjoyed fresh.
