  • 2 tablespoons olive oil
  • 1 tablespoon cornstarch
  • 1 teaspoon smoked paprika
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon onion powder
  • 1/4 teaspoon cayenne pepper (optional, for a little kick!)
  • Salt and freshly ground black pepper to taste

How to Make Crispy Oven Baked Sweet Potato: The Ultimate Guide

Step 1: Preheat the Oven

First things first! Preheating your oven to 400°F (200°C) is crucial. This ensures that your fries will cook evenly and get that delightful crispiness we all love.

Step 2: Prepare Sweet Potatoes

Peel those lovely sweet potatoes and cut them into 1/2-inch thick fries. The thickness is important; too thin, and they’ll burn quickly; too thick, and they won’t get crispy enough.

Step 3: Soak (Optional)

Soaking your fries in cold water for at least 30 minutes helps to remove excess starch. This step is optional but highly recommended if you want extra-crispy results! After soaking, drain and pat them completely dry with a kitchen towel.

Step 4: Toss with Oil & Cornstarch

In a large bowl, toss the fries with olive oil until they’re evenly coated. Then sprinkle in the cornstarch and toss again. This is key for achieving that crunchy exterior!

Step 5: Add Spices

Now it’s time to add flavor! Toss in the smoked paprika, garlic powder, onion powder, cayenne pepper (if using), salt, and pepper. Make sure every fry gets coated with those delicious spices.

Step 6: Arrange on Baking Sheet

Line a baking sheet with parchment paper for easy cleanup. Arrange the fries in a single layer without overcrowding them—this allows air to circulate around each fry so they’ll crisp up nicely.

Step 7: Bake

Pop those fries in the oven and bake for about 20 minutes. After this time, take them out and flip them over gently—this ensures they cook evenly on both sides.

Step 8: Continue Baking

Return the fries to the oven for another 15-20 minutes until they are golden brown and crispy. Keep an eye on them as ovens can vary!

Step 9: Broil (Optional)

For an extra crunch factor, broil them for the last minute or two. Just watch carefully so they don’t burn!

Step 10: Remove and Season

Once done baking, take them out of the oven and sprinkle some extra salt if desired while they’re still hot—it helps enhance their flavor!

Step 11: Serve

These sweet potato fries are best enjoyed immediately while they’re hot and crispy.

Step 12: Garnish (Optional)

For that extra touch of elegance, garnish with fresh rosemary or thyme sprigs before serving.

Step 13: Dipping Sauces

Don’t forget your favorite dipping sauces like ketchup, aioli, spicy mayo, honey mustard, or ranch dressing—they complement these crispy delights perfectly!

Enjoy making this delightful dish! You’ll find it hard not to go back for seconds!

Pro Tips for Making Crispy Oven Baked Sweet Potato: The Ultimate Guide

Making crispy oven-baked sweet potatoes is a delightful experience, and with these tips, you’ll be well on your way to frying perfection!

  • Soak the Fries: Soaking the sweet potato fries in cold water for 30 minutes helps to remove excess starch, leading to a crispier texture when baked.

  • Don’t Skip the Cornstarch: Coating the fries with cornstarch before adding oil and spices creates a thin layer that crisps up beautifully in the oven.

  • Use Parchment Paper: Lining your baking sheet with parchment paper prevents sticking and allows for even heat distribution, ensuring your fries turn golden brown without burning.

  • Space Them Out: Avoid overcrowding the baking sheet; give each fry some room to breathe. This ensures they cook evenly and become perfectly crispy rather than steaming.

  • Keep an Eye on Them: For that extra crunch, broil for a couple of minutes at the end of baking. Just be sure to watch them closely so they don’t burn!

How to Serve Crispy Oven Baked Sweet Potato: The Ultimate Guide

Serving crispy oven-baked sweet potatoes can transform a simple dish into a gourmet experience! Here are some ideas to present this delicious treat.

Garnishes

  • Fresh Herbs: Sprinkling fresh rosemary or thyme over your fries adds a delightful aroma and enhances their visual appeal.
  • Chili Flakes: For those who love a little heat, sprinkling some chili flakes right before serving can kick it up a notch!
  • Zesty Lemon Juice: A squeeze of fresh lemon juice adds brightness and balances the sweetness of the potatoes beautifully.

Side Dishes

  • Garlic Roasted Asparagus: These tender spears roasted with garlic make for a vibrant and healthy side that complements the sweet potato’s sweetness.
  • Quinoa Salad: A refreshing quinoa salad mixed with cucumbers, tomatoes, and a light vinaigrette provides a protein-packed accompaniment that pairs nicely.
  • Grilled Chicken or Tofu Skewers: Adding skewers marinated in herbs and spices gives a savory contrast to the sweet flavor of the fries.
  • Green Salad: A simple green salad dressed with olive oil and vinegar brings freshness to your plate, balancing richness with crispness.
