I've gotta tell you about my trick for crispy baked sweet potato fries that'll blow your mind! These are way healthier than regular fries but taste just as awesome. The golden edges get so crispy and they vanish from our table faster than anything else I make.

Nutritious and Tasty

The cool thing about these fries is all the good stuff inside like fiber and beta-carotene, but you'd never know they're so healthy from the taste. When you bake them, you keep all the nutrients while still getting that amazing crunch everyone wants.

Your Ingredient List

  • What You Need:
    • Sea salt and whatever seasonings you love
    • Cornstarch to make them extra crispy
    • Quality olive oil
    • Sweet potatoes cut to the right size

Creating Food Magic

Season with Care:
Sprinkle on salt and spices right after they come out hot.
Bake Until Golden:
Cook in a 425°F oven and don't forget to flip them halfway.
Arrange Properly:
Leave space between fries on parchment for the crispiest results.
Prep Your Coating:
Mix with cornstarch first then add oil making sure they're fully covered.
Cut Them Evenly:
Slice your sweet potatoes about 1/4 inch thick for best results.

My Top Tricks

Want super crispy fries? Cut them thin, don't skip the cornstarch, and give each piece its own space on the baking sheet. You don't even need to soak them first - just cut, add your stuff and pop them in the oven!

Great Food Combos

These fries go with just about anything from tacos to veggie burgers. You can dunk them in your favorite sauces or just munch on them by themselves when you need a snack.

Kitchen Helpers

You'll want a really sharp knife to get those slices just right. Good quality baking sheets and some parchment paper will help them get extra crispy and make cleaning up super easy afterward.

Recipe FAQs

→ What makes cornstarch important?

It creates a nice crispy layer while baking.

→ Can I prepare these earlier?

Sure! Peel and slice them up to 48 hours ahead, keeping them in water so they don’t brown.

→ How can I keep them crunchy?

Avoid stuffing the pan, cut evenly, and turn them midway while baking.

→ Is it okay to store leftovers?

Store in an airtight container in the fridge for up to four days. Pop them back in the oven to refresh their crunch.

→ What’s the ideal size for cutting?

Go for 1/4” thick and wide strips to make them cook evenly.
