Crispy Oven Baked Sweet Potato Fries

Have you tried to make sweet potato fries at home just to have them turn out soggy? Yup, me too.

These homemade sweet potato fries are always a huge hit thanks to a secret ingredient that makes them crispy.

I can never say no to a plate of fresh cooked fries and sweet potato fries are a great nutritious to classic french fries.

What ingredients do I need to make these Crispy Sweet Potato Fries?

  • Sweet Potatoes. Choose long potatoes, instead of chunkier potatoes, because it makes them easier to cut!
  • Oil. I’m a big fan of avocado oil. We get a huge bottle of it from Costco.
  • Tapioca Flour. This is the secret ingredient that turns the fries from a soggy mess into crispy deliciousness.
  • Seasonings: Salt and garlic powder are used in the recipe, but feel free to sprinkle on a 1/4-1/2 tsp of a few extra seasonings. Paprika, onion powder or chili powder are some great options.

Dairy-Free Ranch Dipping Sauce

I think dipping is the best part of eating fries so I made an easy dairy-free ranch sauce to go with the sweet potato fries. It’s super simple, but does require a variety of spices. I believe that if you have a well-stocked pantry, you can literally make anything store bought at home!

Here’s what you’ll need :

  • Plain Unsweetened Greek Style Dairy-Free Yogurt. I always use Kite Hill Brand. IThe flavor is on point and it’s also the perfect dairy-free sour cream replacement!
  • Apple Cider Vinegar
  • Seasonings: Onion Powder, dill, parsley, chives & seasoned salt.

Other ideas for dipping are good ole ketchup or we love this homemade garlic aioli.

How to Make the Best Baked Sweet Potato Fries

  1. Peel & Cut the Sweet Potatoes. You’ll want to cut evenly sized fries. Keep them thin and all about the same size to help them bake evenly.
  2. Toss the Fries. In a large bowl, toss the fries with oil, then toss in a mixture of the tapioca flour and seasonings.
  3. Ready to Bake! Have your oven preheated and baking sheets prepped with parchment paper to avoid the fries sticking to the pan. Don’t overcrowd the pan…use 2 baking sheets if you need to avoid crowding or overlapping fries.
  4. Flip! Be sure to flip the fries halfway through baking time to ensure they get crispy on all sides.

Crispy on the outside, creamy on the inside, and super delicious! You’ll want to serve these fries immediately with your favorite dips.

These sweet potato fries are perfect as a side dish or an afternoon snack, and they’re 100% kid-appoved! Serve alongside your favorite grilled meats, sandwiches or salads.
