How to Make Southwestern Spiced Sweet Potato Fries with Chili-Cilantro Sour Cream – Step by Step
Preparing the Sweet Potato Fries
Step 1: Preheat your oven to 425°F (220°C). Line two large baking sheets with parchment paper for easier cleanup.
Step 2: Wash and dry your sweet potatoes thoroughly. Using a sharp knife, cut the potatoes into even matchsticks, about 1/4 inch thick and 2 inches long. Try to keep them uniform in size so they cook evenly.
Step 3: In a large bowl, toss the sweet potato fries with olive oil until they’re evenly coated. This helps them crisp up in the oven.
Step 4: In a small bowl, mix together the salt, cumin, chile powder, paprika, black pepper, and cayenne to create your Southwestern spice blend.
Step 5: Sprinkle the spice mixture over the oiled sweet potato fries and toss until they’re evenly coated with the seasonings.
Step 6: Arrange the fries in a single layer on the prepared baking sheets, making sure they don’t overlap. This is crucial for achieving maximum crispiness!
Step 7: Bake for 15 minutes, then flip the fries and continue baking for another 10-15 minutes until they’re golden brown and crispy on the outside.
Making the Chili-Cilantro Sour Cream
Step 1: While the fries are baking, combine all the dip ingredients in a medium bowl: sour cream, lime juice, sweet chili sauce, minced garlic, salt, pepper, and chopped cilantro.
Step 2: Mix well until everything is thoroughly combined. Taste and adjust seasonings if needed.
Step 3: Transfer to a serving bowl and refrigerate until ready to serve with your hot fries.

Pro Tips for Making the Best Southwestern Spiced Sweet Potato Fries with Chili-Cilantro Sour Cream
- For extra crispy fries:Â Soak the cut sweet potatoes in cold water for 30 minutes before cooking. This removes excess starch. Just be sure to dry them thoroughly afterward.
- Spacing matters:Â Don’t crowd the baking sheet! Give each fry plenty of room so they can crisp up instead of steam.
- Even cutting:Â Try to cut your fries as uniformly as possible so they cook at the same rate. A mandoline can help with this if you have one.
- Make ahead option:Â Prepare the chili-cilantro sour cream up to 24 hours in advance to allow the flavors to meld together even more.
- Heat customization: The 1/2 teaspoon of cayenne provides a moderate kick. For milder Southwestern Spiced Sweet Potato Fries with Chili-Cilantro Sour Cream, reduce to 1/4 teaspoon or omit entirely. For spice lovers, increase to 3/4 teaspoon.
- Vegan alternative:Â For a plant-based version of the chili-cilantro sauce, substitute the sour cream with coconut yogurt or vegan sour cream with a squeeze of extra lime juice.
