Crispy Sweet Potato Wedges

Ultra-crunchy sweet potato wedges paired with zesty avocado garlic dip create the ultimate texture and flavor combo for a mouthwatering snack or side. That hard-to-get crunch—which sweet potatoes rarely achieve—becomes totally doable with a few key tricks that turn these healthy spuds into something you'll seriously crave.

I stumbled on the water-soaking trick completely by chance when I got sidetracked making dinner one night. My potatoes ended up sitting in water, and I just went with it—I couldn't believe how much crunchier they turned out! Now I never skip this step for wedges that vanish from plates in seconds.

Smart Potato Selection

• Pick sweet potatoes with flat, even sides for easier cutting—go for regular shapes without many twists or lumps
• Grab medium-sized ones for wedges that bake evenly without edges burning
• The orange-fleshed kinds (sometimes called "yams" in US stores) give you that lovely sweet caramelization
• Skin on or off? Your call—skinless makes for smoother texture while skin-on adds rustic look and extra nutrients

Foolproof Crisping Technique

Smart Cutting

First, slice your sweet potatoes down the middle lengthwise, then cut each half again. Keep going until you've got wedges around 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

Drop your cut wedges in cold water for at least 60 minutes. This might seem like a hassle but it's what makes everything work—it pulls out the extra starch that normally stops them from crisping up. You'll notice the water gets cloudy as this happens.

Complete Drying

After their bath, drain the wedges and wipe them totally dry with paper towels. Any wetness left becomes your worst enemy for crispiness, so don't rush this part. Once they're dry, dust them lightly with cornstarch, creating a thin layer that soaks up any leftover moisture during cooking.

Seasoning Blend

Mix your wedges with olive oil and a combo of paprika, garlic powder, onion powder, chili powder, cayenne (more or less depending how spicy you want them), and dried thyme. Stick to dried herbs instead of fresh ones—fresh herbs have moisture that fights against your crunch goals.

Hot Pan Start

Here's a real game-changer: put your baking trays in the oven while it heats up. When you lay your seasoned wedges on these hot pans, they start sizzling right away, giving that crucial early sear. Leave plenty of space between them—crowding leads to steaming instead of crisping.

Salt Timing Trick

Wait until your wedges come out golden and crunchy from the oven before adding any salt. If you salt before baking, it pulls out moisture and ruins the crispiness. A bit of flaky sea salt right as they come out hot creates that perfect sweet-salty mix.

Dip Creation

While the wedges cook, throw ripe avocado, garlic, a bit of mayo, lemon juice, and fresh herbs into a small food processor or blender. A quick 20-second blend gives you the ideal creamy partner for your crunchy wedges—the cool, garlicky dip perfectly balances the sweet spiciness.

My next-door neighbor popped by once when these were cooking and hung around for 20 minutes just to taste them. She pretended she was "just dropping off some mail" but kept finding excuses to stay as the smell filled my kitchen. When I finally let her try one, she took a bite and immediately wanted the recipe. Now she brings them to every gathering and takes all the credit—but I know exactly where she learned that soaking trick!

Tasty Pairings

Grab these wedges right from the oven when they're crunchiest, with the avocado dip on the side for dunking. They work great with grilled chicken or hamburgers, or set them out with other finger foods on game day. For a full vegetarian meal, eat them with a big salad or plant-based burger.

Fun Flavor Twists

Mix in a spoonful of brown sugar or maple syrup with your spices for a sweet-hot combo. Or go completely different with curry powder, cumin, and a touch of cinnamon for Moroccan-style wedges. If avocados aren't your thing, these taste amazing with regular garlic mayo, spicy sriracha dip, or even a tangy yogurt sauce.

Keeping Leftovers

These wedges taste best fresh out of the oven, but if you have extras, store 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 microwave them) for about 5 minutes to bring back some crispiness. The avocado dip lasts up to two days in the fridge with plastic wrap pushed right against the surface to prevent browning.

Clever Cook's Tips

• Cut across the grain of the sweet potato so your wedges don't fall apart
• In a rush? Even soaking for 30 minutes will make them noticeably crunchier
• 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 enjoying them, 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 off his jacket. Sometimes the best way to win over veggie haters is just to make their vegetables super crunchy!

Frequently Asked Questions

→ Why soak the sweet potatoes first?

Soaking gets rid of extra starch, helping the wedges turn crispier in the oven. It’s an essential step for the best texture.

→ Can I skip the cornstarch step?

Cornstarch gives the crispiest result, but you can leave it out. The wedges will still taste great, just not as crunchy.

→ How do you keep the dip green?

Lemon juice keeps it from browning. For storage, press plastic wrap directly on the dip's surface before refrigerating. Use within a day.

→ Can I prep this in advance?

They’re best served hot, but you can cut the potatoes and prepare the dip ahead of time, then bake just before serving.

→ Why salt after baking?

Salting before baking pulls out moisture and makes it harder to crisp. Adding it at the end keeps the texture perfect.

→ Is this air fryer-friendly?

Totally! Cook at 380°F for 15 minutes, shaking halfway. Don’t overcrowd the basket—work in batches if needed.
