Are sweet potato fries gluten-free by default?

Most plain sweet potato fries are naturally gluten-free since sweet potatoes contain no gluten. However, restaurant or frozen sweet potato fries sometimes include a wheat-based coating or are fried in shared oil, which can introduce gluten. Always check labels and ask about preparation methods if you’re highly sensitive. For total peace of mind, make your own fries at home with gluten-free coatings like cornstarch, arrowroot, or potato starch.

How do you make sweet potato fries extra crispy without gluten?

Crispy gluten-free sweet potato fries are possible with a few smart steps. Soak the cut sweet potatoes in cold water for at least 30 minutes, dry them well, and toss in a thin layer of gluten-free starch. Bake or air fry at high heat and give the fries space so they roast, not steam. Flipping them halfway and seasoning right after cooking helps lock in that golden crunch.

What are the best dipping sauces for gluten-free sweet potato fries?

Dips bring out the sweet and savory flavors of gluten-free sweet potato fries. Greek yogurt dip with lemon and dill, spicy chipotle mayo, classic ketchup, honey mustard, and creamy avocado-lime sauce are all favorites in our house. Always check that any store-bought condiments or ingredients are gluten-free.

Can you freeze and reheat gluten-free sweet potato fries?

Yes! Let cooked fries cool completely, then freeze in a single layer before transferring to a freezer-safe bag. Reheat directly from frozen in a hot oven or air fryer. This method helps maintain crispiness and is perfect for prepping snacks ahead of time or using up leftovers.

Instructions

Peel (optional) and cut sweet potatoes into sticks about 1/4 to 1/2 inch thick for even cooking.
Soak the cut fries in a bowl of cold water for at least 30 minutes to remove excess starch.
Drain and dry sweet potato sticks thoroughly with a clean towel.
Toss fries with cornstarch (or arrowroot/potato starch) to coat lightly and evenly.
Add oil, smoked paprika, garlic powder, cayenne (if using), and sea salt. Toss until well coated.
To Bake: Preheat oven to 425°F (220°C). Spread fries in a single layer on a parchment-lined baking sheet. Bake 15 minutes, flip, and bake another 10–15 minutes until golden and crisp at the edges.
To Air Fry: Preheat air fryer to 400°F (200°C). Arrange fries in a single layer, air fry 15–20 minutes, shaking halfway through, until crisp and golden.
To Pan Fry: Heat 1/4 inch oil in a heavy skillet over medium-high. Cook fries in batches, turning, until golden and crisp. Drain on a rack or paper towels.
Season immediately with extra salt and garnish with fresh herbs. Serve hot with your favorite dipping sauces.

Notes

For extra crispy fries, don’t skip the soaking and drying step. Serve with gluten-free dips like Greek yogurt-lemon-dill, chipotle mayo, or honey mustard. Leftovers reheat best in the oven or air fryer. Freeze cooled fries in a single layer, then store in a freezer bag; reheat from frozen for best crispiness.
