Ingredients

2 sweet potatoes
Water, to taste
1 tablespoon corn starch
2 tablespoons oil
1 pinch salt
1/2 avocado
1/2 lime
1 clove garlic
1 tablespoon fresh parsley
1 jalapeño pepper
1/2 cup nonfat plain Greek yogurt
1 dash milk
Salt, to taste
Ground black pepper, to taste

Instructions

Step 1: Peel the sweet potatoes and cut them lengthwise into 1/4-inch (0.6 cm) thick matchsticks. Aim for thinner fries if possible for more even cooking.
Step 2: Place the cut fries into a bowl of cold water and refrigerate for at least 1 hour or up to overnight. After soaking, drain and pat them dry with a kitchen towel; it’s okay if they’re not completely dry.
Step 3: Preheat your oven to 425°F (220°C).
Step 4: Put the corn starch in a plastic bag and add the sweet potato fries. Seal the bag with some air inside and shake gently to coat the fries evenly with the starch.
Step 5: Arrange the fries on a parchment-lined baking sheet. Drizzle with oil and toss to coat thoroughly. Spread the fries out so they aren’t touching for better crisping.
Step 6: Bake for 20 minutes, then remove, flip the fries, rotate the pan, and bake for another 20 minutes until they start to brown.
Step 7: While the fries bake, prepare the avocado sauce by blending the avocado, lime juice, garlic, parsley, and jalapeño until smooth.
Step 8: Add Greek yogurt to the mixture and blend again until creamy and smooth.
Step 9: If the sauce is too thick, add a dash of milk to reach your desired consistency. Season with salt and pepper to taste.
Step 10: Turn off the oven and prop the door open slightly. Let the fries crisp in the warm oven for 15 minutes.
Step 11: Remove fries from the oven, sprinkle lightly with salt, and serve immediately with the avocado dipping sauce.

Tips & Variations

Soaking the fries helps remove excess starch, making them crispier after baking.
For extra heat, add more jalapeño or a pinch of cayenne pepper to the sauce.
Use olive oil or avocado oil for a heart-healthy option.
If you prefer a vegan version, substitute the Greek yogurt with a plant-based yogurt.

Storage

Store baked sweet potato fries in an airtight container in the refrigerator for up to 3 days. Reheat in an oven or air fryer to regain crispness rather than microwaving, which can make them soggy. Keep the avocado sauce refrigerated separately and consume within 2 days for best freshness.

How to Serve

FAQs

Can I use regular potatoes instead of sweet potatoes?

Yes, you can use regular potatoes, but baking time and soaking requirements may vary slightly. Sweet potatoes offer a natural sweetness and soft interior that pairs well with the avocado sauce.

How do I make the fries crispier?

Ensuring fries are well dried after soaking and spacing them out on the baking sheet helps. Tossing with a bit of cornstarch also contributes to a crispy texture. Finishing them in the warm oven with the door ajar helps remove moisture for extra crispness.
