Crunchy sweet potato wedges paired with garlic avocado aioli mix amazing textures and tastes for a mouthwatering snack or side. Getting that hard-to-achieve crunch with sweet potatoes isn't tough anymore—just follow a few key steps that'll turn these healthy spuds into something you won't be able to stop eating.

I stumbled on the water-soaking trick when I got sidetracked making dinner one night. My potatoes sat in water while I dealt with something else, and I was amazed at how much crunchier they turned out! Now I never skip this step—these wedges vanish from plates in seconds flat.

Ideal Potato Selection

  • Go for sweet potatoes with flat, straight sides for easier cutting—try to find evenly shaped ones without many twists or knobs
  • Stick with medium-sized ones for wedges that bake evenly without getting burnt
  • The orange-flesh kinds (sometimes called "yams" in US stores) give you that lovely sweet caramelization
  • Your call on skin—taking it off makes texture more even while keeping it on adds rustic look and extra nutrients

Foolproof Crisping Technique

Smart Cutting

First, cut your sweet potatoes down the middle lengthwise, then split each half again. Keep cutting until you've got wedges about ¾-inch thick. Making them all the same size means they'll cook together—you don't want some burnt while others stay raw inside.

Water Bath Magic

Put your cut wedges in cold water for at least an hour. This might seem fussy but it's worth it—the water pulls out extra starch that normally keeps sweet potatoes from crisping up. You'll notice the water turns cloudy as this happens.

Complete Drying

After their bath, drain the wedges and wipe them totally dry with paper towels. Any wetness left will ruin your crunch factor, so don't rush this part. Once they're dry, toss them in a bit of cornstarch, which makes a super-thin layer that soaks up any leftover moisture during cooking.

Seasoning Mix

Mix your wedges with olive oil and a combo of paprika, garlic powder, onion powder, chili powder, cayenne (more or less depending on how spicy you want them), and dried thyme. Don't use fresh herbs—they've got moisture that works against getting crispy results.

Hot Pan Trick

Here's a game-changer: stick your baking sheets in the oven while it heats up. When you put your seasoned wedges on these hot pans, they start sizzling right away, giving you that important first sear. Keep them spread out—crowding leads to steaming instead of crisping.

Salt Timing

Wait until the wedges come out golden and crunchy from the oven before adding salt. Salting before cooking pulls out moisture and ruins crispiness. A dash of flaky sea salt when they're fresh from the oven gives you that perfect sweet-salty combo.

Dip Creation

While the wedges cook, throw ripe avocado, garlic, a little mayo, lemon juice, and fresh herbs in a small food processor or blender. A quick whirl and you've made the perfect creamy partner for your crunchy wedges—the cool, garlicky dip balances the sweet spiciness just right.

One time my neighbor dropped in while these were baking and hung around for 20 minutes just to try them. She pretended she was "just dropping off mail" but kept finding excuses to stay as the smell filled my kitchen. When I finally let her sample one, she took a bite and right away asked how I made them. Now she brings them to every gathering and takes all the credit—but I know exactly where she learned that soaking trick!

Ways To Enjoy

Dish these wedges up right from the oven when they're crunchiest, with the avocado aioli in a bowl for dipping. They go great with grilled chicken or burgers, or add them to your game day snack lineup. For a full vegetarian meal, eat them with a big salad or veggie burger.

Tasty Twists

Try making them sweet and spicy by adding a spoon of brown sugar or maple syrup to your spices. Or go for something totally different with curry powder, cumin, and a hint of cinnamon for Moroccan-style wedges. If avocados aren't your thing, these taste great with regular garlic aioli, spicy mayo, or even a tangy yogurt dip.

Keeping Leftovers

These wedges taste way better fresh, but if you have extras, put them in a paper bag instead of a sealed container—this helps keep some crunch by stopping moisture buildup. Warm them in a hot oven (never use a microwave) for about 5 minutes to bring back some crispiness. The avocado dip stays good for up to two days in the fridge if you press plastic wrap right onto its surface to stop it from turning brown.

Pro Kitchen Tricks

  • Cut across the sweet potato grain for wedges that don't fall apart
  • In a rush? Even soaking for 30 minutes will make them noticeably crispier
  • A quick oil spray just before serving adds extra richness and shine

The first time I made these for my fussy nephew, he eyed them doubtfully and said he "couldn't stand sweet potatoes." After watching everyone else dig in, he tried one reluctantly—then ate seven more! Now when his family visits, he asks if we're having "the orange fries" before he even takes his jacket off. Sometimes all it takes to win over veggie haters is making them super crunchy!

Frequently Asked Questions

→ What’s the point of soaking the potatoes?
Soaking pulls out some of the starch on the potatoes' surface, helping them crisp better while they bake. It’s a small step to get that perfect crunch.
→ Can I skip the cornstarch?
Cornstarch makes the potatoes extra crispy, but if you don’t have any, that’s okay. The wedges might not be as crunchy, but they'll still be tasty with the seasonings.
→ What keeps the avocado sauce fresh and green?
Lemon juice keeps it from browning too fast. For storage, press plastic wrap right against the dip’s surface and keep it in the fridge. Use it within a day, though!
→ Does this work for meal prep?
The wedges are best when they’re hot and fresh from the oven. You can prep the potatoes and make the sauce ahead, then bake the dippers when you need them.
→ Why add the salt after baking?
Salting before baking pulls out too much moisture and ruins the crispy texture. Add salt once they’re done for the ideal salty crunch.
→ Can I cook these in an air fryer?
Absolutely! Cook at 380°F for around 15 minutes, shaking a bit halfway through. Avoid crowded baskets to get the best results.

Ingredients

→ Sweet Potato Wedges

01 2 tablespoons olive oil
02 1-2 tablespoons corn starch or cornflour
03 2 large sweet potatoes, washed well and sliced into wedges

→ Seasoning

04 Sea salt to taste
05 ½ teaspoon red chili powder (optional)
06 2 teaspoons garlic powder
07 2 teaspoons sweet paprika
08 2 teaspoons dried thyme
09 ¼ teaspoon cayenne pepper
10 ½ teaspoon onion powder

→ Avocado Garlic Aioli

11 1 clove garlic, finely minced
12 Sea salt to taste
13 1 large ripe avocado
14 2 teaspoons freshly squeezed lemon juice
15 2 tablespoons whole egg mayonnaise

Instructions

Step 01

Put the wedges in a big bowl filled with cold water. Let them sit for at least an hour to take out the extra starch.

Step 02

Move the oven racks closer to the top, then preheat to 450°F (230°C). Mist two baking trays with oil or cooking spray and place them in the oven to heat up.

Step 03

After soaking, let the wedges dry completely using paper towels. Add cornstarch to a large zip bag, toss in the wedges, seal it with some air, and shake it so everything gets coated evenly.

Step 04

Shake off any extra cornstarch, toss the coated wedges with olive oil in a bowl, and sprinkle on all the spices—except salt. Mix until they're evenly coated.

Step 05

Take the hot baking trays out of the oven, spread the wedges on them with a little space in between, and bake for about 15 to 20 minutes. Use a fork to check if they're tender.

Step 06

Flip the wedges over, keeping some space between each one, and pop them back in the oven for 5-10 minutes till they get crispy with golden edges.

Step 07

Turn the oven off but leave the wedges inside with the door slightly open for 5 minutes. This will make them even crunchier.

Step 08

As the wedges crisp, toss the avocado, garlic, mayonnaise, and lemon juice into a small blender or food processor. Blend for about 20 seconds till it's creamy and smooth, then season with salt.

Step 09

Add a good sprinkle of salt to the hot wedges and serve them right away with the creamy avocado aioli for dipping.

Notes

  1. Soaking the wedges in water helps get rid of starch, which makes them crispier.
  2. Give the wedges enough space on the tray so air can circulate, making them cook evenly.
  3. You can make the aioli a day early. Keep it in the fridge with plastic pressed against the surface to stop it from browning.
