These Pesto Sweet Potato Fries combine crunchy fries with a tasty twist of basil pesto. They’re colorful, delicious, and perfect for snacking or as a side dish!
Every bite is a flavor surprise that makes me smile. I often serve them with a dip on the side, but honestly, they’re great on their own! Can’t resist that crunch! 😋
Ingredients & Substitutions
Sweet Potatoes: These provide a naturally sweet and creamy texture. If you’re short on sweet potatoes, regular potatoes work, but you’ll miss the unique flavor. Yams are also a tasty alternative!
Pesto: The basil in the pesto adds a burst of freshness. If basil isn’t available, you can use spinach or arugula for a different flavor. For a nut-free option, skip the pine nuts or use sunflower seeds instead. You can also use store-bought pesto if you’re in a hurry!
Parmesan Cheese: This adds a salty richness. If you’re looking for a dairy-free version, try nutritional yeast for a cheesy flavor without the dairy. You could also use Pecorino Romano as a substitute for a stronger flavor.
How Can I Get My Sweet Potato Fries Extra Crispy?
Getting sweet potato fries crispy can be tricky, but it’s all about moisture control and proper cooking technique. Here are some tips to help you achieve that perfect crunch:
- Slice your fries evenly; this helps them cook uniformly.
- Leave the skin on—this adds texture and helps hold them together.
- Don’t overcrowd the baking sheet. Give each fry space for hot air to circulate.
- Turn the fries halfway through baking; it ensures even browning.
- For added crispiness, consider soaking cut fries in cold water for 30 minutes before baking. This removes excess starch and helps achieve that crispiness!

For the Pesto:
- 1/2 cup fresh basil leaves, packed

How Much Time Will You Need?
This recipe will take about 10 minutes of prep time and around 30 minutes of baking time. You can have your delicious Pesto Sweet Potato Fries ready in about 40 minutes total. Perfect for a quick side dish or snack!
Step-by-Step Instructions:
1. Preheat the Oven:
First, preheat your oven to 425°F (220°C). While it heats up, line a baking sheet with parchment paper to keep your fries from sticking and make cleanup easier.
2. Prepare the Sweet Potatoes:
Wash and dry the sweet potatoes thoroughly. Using a sharp knife, cut them into even-sized fries that are about 1/2 inch thick. You can keep the skin on for added texture and nutrients—it tastes great!
3. Season the Fries:
Place your cut fries into a large mixing bowl. Drizzle with 2 tablespoons of olive oil, and season with salt and freshly ground black pepper to your liking. Toss everything together so the fries are evenly coated with the oil and seasoning.
4. Bake the Fries:
Spread the fries out in a single layer on your prepared baking sheet. Make sure they aren’t overcrowded—this helps them become crispy! Bake in the oven for 25-30 minutes, turning them halfway through. You want them to look golden brown and crispy on the edges when they’re done.
5. Make the Pesto:
While the fries are baking, it’s time to whip up the pesto. In a food processor, combine the fresh basil leaves, grated Parmesan cheese, pine nuts, garlic cloves, and lemon juice. Pulse these ingredients together until they form a coarse paste.
6. Add the Olive Oil:
With the food processor running, slowly drizzle in the extra virgin olive oil (1/3 cup) until the pesto is smooth and well combined. Taste it and add salt and pepper as needed for extra flavor.
7. Combine and Serve:
Once your sweet potato fries are baked to crispy perfection, transfer them to a serving platter. Drizzle the fresh pesto generously over the hot fries. They’ll be so inviting!
8. Enjoy!
Serve the fries immediately while they’re warm and crispy! They’re perfect for a tasty snack or as a unique side dish. The combination of sweet potatoes and vibrant pesto is simply irresistible!
These fries offer a delightful blend of sweet and savory flavors, enhanced by the bright taste of fresh pesto. Enjoy every crispy bite!
Can I Use Regular Potatoes Instead of Sweet Potatoes?
Yes, you can absolutely use regular potatoes if you prefer! Keep in mind that the flavor will be different, and you may need to adjust the cooking time slightly since regular potatoes might cook a bit faster or slower depending on the type.
How Do I Store Leftover Fries?
To store any leftover fries, place them in an airtight container in the fridge. They’re best enjoyed within 2-3 days. To reheat, simply pop them in the oven at 400°F (200°C) for about 10-15 minutes to regain their crispiness.
Can I Make the Pesto in Advance?
Absolutely! You can prepare the pesto up to a week in advance. Just store it in an airtight container in the fridge, and cover the surface with a thin layer of olive oil to prevent browning. Give it a stir before using!
What If I Don’t Have Pine Nuts?
No problem! You can substitute pine nuts with walnuts, almonds, or even sunflower seeds for a nut-free option. Each will give a slightly different flavor, but they’ll all be delicious!
