How to make spicy sweet potato fries

- Prep the potatoes: Preheat your oven and line a baking sheet with parchment paper. Put the sweet potato strips in a large bowl and toss them with olive oil and all the spices.
- Arrange your potatoes on a baking sheet: This step is important for the crispiness of your potatoes. Spread the spicy sweet potato fries in a single layer on the baking sheet and drizzle the remaining tablespoon of olive oil over the top. Make sure there's space between the fries.

Tips to make perfect (crispy) spicy sweet potato fries
Around this neck of the woods, there's nothing but love for the sweet potato fries that come out of the oven that aren't quite crispy. The tender ones are good, too! That said, if you only want to eat them at crisp perfection, follow these expert tips:
- For crispier sweet potatoes, try soaking them for at least an hour in cold water before baking.
- Once you've oiled the fries, dust them with cornstarch. Rub the cornstarch into the fries and then add the rest of the spices.
- Try experimenting with cutting them different widths to see how you like them best ā just make sure that each batch you make are all roughly the same size so they cook evenly.
- Make sure not to crowd the sheet pan or they will be too soft.
