Crispy Oven Baked Sweet Potato Fries

Once I started making baked sweet potato fries in the oven at home, there was no going back. I now make all kinds of sweet potato sides like roasted sweet potatoes or air fryer sweet potato cubes but these are always the most requested.

As much as I love french fries or potato wedges, homemade sweet potato fries are hard to beat. They come out perfectly crispy in the oven and seasoned to perfection. I love dipping them in fry sauce or burger sauce, but honestly any of your favorite dipping sauces work great!

Recipe Ingredients

Baked sweet potato fries only require a few simple ingredients! Here is what you will to make these fries.

  • Sweet potatoes: Four medium sweet potatoes work best. Look for ones that are longer and less curvy so they cut into even fries more easily.
  • Oil: Olive oil or canola oil both work great. Canola oil gives slightly crispier results.
  • Seasonings: I love the classic combination of kosher salt, pepper and garlic powder. Sea salt could be used in place of kosher salt.
  • Cornstarch: The secret to extra-crispy fries! Toss the fries in a little cornstarch before baking for the best results.

Favorite Seasoning Ideas

There are so many different ways to customize your fries! I took the classic approach in this recipe, but below are a few of my other favorite spices.

  • Spicy: Oil, kosher salt, pepper, garlic powder and paprika (or chili powder, cayenne pepper or easy chili seasoning).
  • Cinnamon-sugar: Oil, kosher salt and cinnamon sugar.
  • Rosemary: Oil, kosher salt, pepper, garlic powder and rosemary.
  • Italian: Oil, kosher salt, pepper, garlic powder and Italian seasoning.

How To Make Baked Sweet Potato Fries

Follow these simple steps for perfectly crispy oven baked sweet potato fries every time.

  1. Cut sweet potatoes into matchsticks. Peel your sweet potatoes and cut off both ends. Slice in half horizontally, then cut halves vertically into 4 pieces. Slice again each piece vertically into 8 pieces then finally cut the sweet potato pieces into thin sticks, about 1/4″ inch thick and 3″ inch long.
  2. Soak fries in cold water: For extra-crispy fries soak uncooked matchsticks in large bowl with ice cold water for 30 minutes. Drain then pat dry and place in a zip-top bag with 2 Tablespoons cornstarch and shake until evenly coated.
  3. Place on baking sheet: Place the sweet potato sticks in a single layer on a baking sheet lined with foil or parchment. Toss with olive oil.
  4. Bake: Bake at 415°F for 15 minutes which is hot enough to crisp the edges without burning the natural sugars in the sweet potato. Sprinkle the seasoning mixture evenly over the fries, flip and bake an additional 10 to 15 minutes or until crisp

Use the air fryer: Instead of sweet potato fries in the oven, air fry them in 2 to 3 batches so the fries have room to crisp up rather than steam. Preheat the air fryer to 380°F and cook for about 12 minutes, turning halfway through, or until crisp.

Expert Tips

  • Thickness: Cut to 1/4 inch. Any thicker and the outside can’t crisp before the inside overcooks.
  • Evenly sized: One of the main keys to making the fries crispy is to cut them into evenly sized matchsticks so that they all bake the same.
  • Peeling: While I like to peel them for smoother fries, sweet potato skins are edible and add extra texture and nutrition. Some say it also makes them crispier!
  • Cornstarch: Add the fries to a bag and shake 2 Tablespoons of cornstarch on top so you have a thin coating. The starch coating helps absorb surface moisture so the fries crisp while baking.
  • Oil: Use canola, grapeseed, sunflower or peanut oil for a crispier edge.
  • Bake on a metal rack over a baking sheet: Elevating the fries lets hot air circulate underneath so you get crispy edges on all sides without flipping.
  • Don’t overcrowd the pan: Spread the fries in a single layer with space between each one. Crowding causes steam to build up which makes them soft instead of crispy. Flip halfway through so both sides get evenly browned.

Notes

Extra-crispy fries: Soak uncooked fries in large bowl with ice cold water for 30 minutes. Drain then pat dry and place in a zip-top bag with 2 Tablespoons cornstarch and shake until evenly coated. Use canola oil when baking. 
Air fryer: This is my favorite way to cook these fries, you will just need to cook in 2 to 3 batches. Preheat the air fryer to 380°F. Cook about 12 minutes (turning half way through), or until crisp.
Favorite Seasonings: There are so many different ways to season them! I took the classic approach in this recipe, but below are a few of my other favorites.
  • Classic: Oil, kosher salt, pepper and garlic powder
  • Spicy: Oil, kosher salt, pepper, garlic powder and paprika (or chili powder or chili seasoning)
  • Cinnamon-sugar: Oil, kosher salt and cinnamon sugar
  • Rosemary: Oil, kosher salt, pepper, garlic powder and rosemary
  • Italian: Oil, kosher salt, pepper, garlic powder and Italian seasoning
How to Cut Fries: Since the sides of the potatoes are rounded, I like to slice them off vertically to flatten the surface.
  1. Peel the sweet potato and then cut off the ends.
  2. Slice in half horizontally, creating two equal-sized pieces about 3 inches long.
  3. Next, cut the pieces in half vertically. Once you have 4 pieces, cut each piece in half vertically again to make 8 pieces.
  4. Slice each piece vertically into 1/4 inch fries. Each piece should produce about 3-5 fries.
Fry sauce: Combine 1/4 cup mayo and 1 1/2 Tablespoons ketchup. Add a dash of seasoned salt.
