Frequently Asked Questions
- → What’s the reason for soaking the fries in water?
- Soaking helps get rid of extra starch, which makes the fries bake up even crispier. A cold water soak for 30 minutes works wonders for texture.
- → How do I get them extra crispy?
- Make sure to dry the fries completely after soaking, don’t overcrowd the tray, and use a preheated baking sheet. A light coating of cornstarch can also bring some crunch.
- → Can I prep them in advance?
- You can! Cut and soak the sweet potatoes ahead of time. Just leave them in cold water in the fridge (up to 24 hours), then dry, season, and bake when you’re ready.
- → Do I need to peel the sweet potatoes?
- You don’t have to peel them. The skin adds nutrients and extra texture, but if you prefer them peeled, that works too. Just give the sweet potatoes a good clean either way.
- → What pairs well with these fries?
- These fries make a great side for burgers, sandwiches, or grilled meats. Try them with sauces like chipotle mayo, garlic aioli, or classic ketchup for dipping.
