How to bake sweet potato fries
- Cut equal-sized strips – Aim for precision cuts for even baking. Use sharp chefs knife to cut ½ inch thick potatoes. I chose to leave the skin on as there are lots of nutrients there and the skin helps to crisp up better. Feel free to peel off the skin.
- Soaking – Starch in potatoes prevents it from turning crispy. After cutting fries always soak them in water preferably ice cold bath water for about 30-45 minutes (if you have time soak them for few hours). Soaking draws the excess starch from the potato fingers. It also helps in turning the fries crispy when baked. Once soaked, drain water completely. Pat dry on kitchen towel.
- Coating with corn starch – Highly recommend you don’t skip this step. Sweet potato needs a extra help to crisp up perfectly. A thin layer of corn flour coating aids to crispy fries. Once coated with corn flour make sure to shake off all the excess corn starch. Excess coating of corn starch will make your fries not just soggy but predominant taste of corn starch is ickiest. Pro-tip : if you are allergic to corn or corn starch, substitute with allow root powder.
- Spice it up – A simple spice mix of garlic, chili powder (because you want to balance out the sweetness of the potatoes a little) and salt works just great! If you like baked sweet potato fries a little extra spicy, you can adjust the spice levels to your preference.
- Canola oil – or you can use soy bean oil, ghee, vegetable oil, grape seed oil crisps up the fries better.
- Baking – Bake on high heat, 400 F. Flip the fries half way down the baking time. Pro-tip : baked potato fries wont feel completely crisp when it hot.
- Salt at the end – wait to salt the fries until the end. Once baked, transfer to bowl and give it a good shower of fine sea salt. Toss well.

Comments & Reviews
Adelene says
Just wondering when to add the garlic powder? It’s listed on ingredients list, but no mention of it in directions.
Jyothi Rajesh says
Sorry about the confusion. Updated the recipe, please add garlic powder along with chili powder (step 4).
Helaine Green says
The fries tasted great but weren’t crisp. I followed the recipe exactly as recommended hoping for crispy fries. Other than frying them in oil or having an air fryer, is there some way to get crispy sweet potato fries?
Jyothi Rajesh says
Did you try leaving oven door open in the end trick Helaine?
DD says
All i got were soggy fries with a powder coating on them. Worse fries ever.
Jyothi Rajesh says
I’m sorry you had some issues. Please let me know if you followed all the tips mentioned in the recipe? Did you skip any step?
Here are some pointers that can be helpful-
Did you pre-heat the oven with the fries inside?
Soaking definitely will help, the longer the better.
Don’t use convection.
Leave the oven door open at the end as mentioned in the recipe.
Hope this helps.
Anne Fescada says
I don’t even know how to rate this, because half-way through cooking, they were completely burned on the bottom side. I went ahead and finished them as directed, but they’re still completely soggy. Help! I have no idea what I did wrong.
Step says
I’m just guessing here, but did you pre-heat the oven with the sticks inside? Soaking for as long as you have time to will help. Don’t use convection. Soggy AND burnt? That’s a neat trick. I don’t know how you did that. Try holding your tongue out of the other side of your mouth. That works for me sometimes. You could try cutting the fries larger. That might work. Best of luck!
Jyothi Rajesh says
If you are asking how I left the oven door open, my oven door does stay open about a 1 to 1.5-inch gap if I just pulled the door and left it. I don’t know how it stays open like that, but it does. I need to push slightly hard to shut it completely and that’s how it works. You could use a wooden spatula and stick it near the opening of the door so it stays open. Or you can follow any trick that you have been using.
Mallory says
Delicious! Modified the spices a bit, I did 1/2 tsp garlic powder, 1/2 tsp salt, 1/2 paprika and 1/4 tsp pepper. I also sprinkled Himalayan Pink Salt on it after done baking. It wasn’t as crispy as I would have liked, but pretty good for my first try!
April says
