Sweet potato fries are one of those sides that always disappear fast at my table. I love how they bring that sweet-and-savory balance, and with the air fryer, they come out crispy without the grease. If you’re just getting into Air Fryer Recipes, this is the perfect beginner-friendly one to try. When my kids see these fries on the table, they rush to grab them before the ketchup even hits the plate! If you’ve enjoyed dishes like my Cajun Chicken Pasta, this recipe is another quick win you’ll love.

What You’ll Need
Here’s what I keep on the counter when making these:
- Sweet potatoes — I like medium-sized ones because they’re easier to cut evenly.
- Olive oil — just a little drizzle helps the spices stick.
- Seasonings — salt, black pepper, garlic powder, and paprika. I sometimes add a pinch of cayenne for heat.
- Cornstarch — helps make the fries extra crispy.
- Air fryer — my go-to tool for weeknight sides.
Pro tip: fresh garlic powder always gives a little flavor boost compared to the older jar hiding at the back of the spice rack. If you love comforting bowls like my Instant Pot Lentil Soup, these fries are the crunchy sidekick you didn’t know you needed.
Step-by-Step Guide to Air Fryer Sweet Potato Fries
Making fries in the air fryer is easier than you think! If you’ve cooked Slow Cooker Chicken and Rice, this will feel like a breeze.
Step 1 — Prep the sweet potatoes
Peel your sweet potatoes (optional, but I like them peeled for a cleaner crunch) and cut into thin fries. Aim for even thickness so they cook evenly. I like to keep them about ¼-inch wide.

Step 2 — Soak for crispiness
Place the fries in a bowl of cold water and let them soak for 20–30 minutes. This step washes off extra starch, which helps them crisp up instead of going soggy.

Step 3 — Dry and season
Pat the fries completely dry with a clean towel. Toss them with olive oil, cornstarch, and your seasonings until evenly coated. I always taste a little of the seasoning mix before tossing—just to make sure it’s balanced.

Step 4 — Air fry in batches
Arrange the fries in a single layer in your air fryer basket. Cook at 400°F (200°C) for about 12–15 minutes, shaking halfway. Don’t overcrowd the basket or they’ll steam instead of crisp.

Step 5 — Serve hot
Sprinkle with a little extra salt or parmesan right after frying. I like to serve mine with ketchup or a quick garlic aioli for dipping.

Pro Tips & Easy Swaps
- Cut the fries thin and even—thicker cuts take longer and may not crisp.
- Always soak the fries first. Skipping this step makes them softer.
- Add smoked paprika for a deeper, BBQ-like flavor.
- Use avocado oil instead of olive oil for a higher smoke point.
- Toss with parmesan right after cooking for a cheesy finish.
- Try cinnamon sugar instead of savory spices for a fun sweet version.
- Cook in small batches so they don’t steam.
- Reheat leftovers in the air fryer for 3 minutes at 375°F to bring back crispiness.
Serving Ideas & Variations
These fries go with almost anything! I love pairing them with burgers, grilled chicken, or even a simple salad. Here are some fun twists:
- Garlic aioli dip
- Ranch dressing for dipping
- Spicy sriracha mayo drizzle
- Parmesan + parsley topping
- Honey mustard dip
- Cinnamon sugar sweet fries
- Pair with BBQ chicken sandwiches
Common Mistakes (and How to Fix Them)
- Overcrowding the basket: Fries steam instead of crisp → Cook in batches.
- Skipping the soak: Fries turn limp → Always soak for 20–30 minutes.
- Not drying well: Excess water causes soggy fries → Pat completely dry.
- Using too much oil: Makes fries greasy → Just 1–2 tsp is enough.
