These spicy sweet potato fries are baked in the oven until they’re crispy and delicious!

I love sweet potato fries and I love spicy food so I’m scratching my head why it’s taken me so long to put these things together. We recently had some deliciously spicy sweet potato fries that came from the freezer and while I loved them, I figured it wouldn’t be that hard to recreate them on my own!

One of the tricks to making these fries nice and crispy is to toss them with cornstarch before you toss them in oil. The cornstarch helps soak up extra moisture and it encourages browning. That’s part of why these sweet potato fries become brown and crispy in the oven without needing to be fried. It’s like magic! But if you don’t have cornstarch, you can still make these fries and they’ll be nice and spicy. Just be sure you bake them long enough to become brown!

The other tip is to try to cut your sweet potato into even-sized pieces. I know it can be a little tricky depending on the shape of your sweet potato, but try to cut them to a consistent size and thickness. This helps all the pieces to cook and brown at the same speed. You’ll end up with crispier fries in the end!

For perfectly crispy fries:

  • Cut the fries as evenly as possible, so they’ll all cook in the same amount of time.
  • You may need to spread the fries out onto two different baking sheets to be sure you can fit them into a single layer.
  • When you’re flipping the fries halfway through the baking time, swap the placement of the baking trays, for more even cooking.

I used 1/2 teaspoon of chipotle chili powder on this first batch and they were quite spicy. Not so spicy I couldn’t eat them but I definitely needed some ketchup on the side! (Then again, I have a secret love affair with ketchup and there is never enough to satisfy me, so maybe it wasn’t the spice?) If you’re not sure about how spicy you’d like these to be, you may want to start with just 1/4 teaspoon and increase it later.
