Can you freeze sweet potato fries?
I have not had great luck with freezing this recipe. They sure don’t freeze well before baking and they only froze ok after baking but I couldn’t get them to crisp back up when it came time to reheat and serve them. I would not freeze this recipe.
These sweet potato fries actually don’t store well at all. I’d suggest making as many as you are going to eat and not more so that you don’t have leftovers. They just aren’t very good reheated.

The BEST Crispy Homemade Sweet Potato Fries
Ingredients
- 1 pound sweet potatoes, peeled
- 2 tablespoons neutral oil, olive, vegetable, canola, etc. all work
- 2 tablespoons cornstarch
- 1/2 teaspoon garlic powder
- 1/2 teaspoon smoked paprika
- table salt, to taste
Instructions
- Cut your sweet potatoes into 1/4 inch square fry-shaped pieces. Consistency in the thickness of the potato is key for evenly and properly cooked potatoes.
- Place the cut sweet potatoes in a bowl and cover with cold water. Let soak for at least 30 minutes or up to 12 hours (they can soak overnight without issues).
- After the sweet potatoes soak, remove from the water and pat dry with a clean dish towel or paper towels.
- Add the dry sweet potatoes to a large bowl or zipper-top bag and drizzle with the oil. Toss well to coat evenly.
- In a small bowl, combine the cornstarch, garlic powder, and smoked paprika. Sprinkle over the oiled sweet potatoes and toss again to evenly coat.
- Preheat the oven to 425 degrees F.
- Spread the sweet potatoes in an even layer on a parchment-lined baking sheet.
- Bake in the preheated oven for 15 minutes.
- Remove from the oven and use a spatula to flip every fry over, one by one.
- Return the oven and bake for an additional 10 to 15 minutes.
- Remove from the oven and sprinkle with salt.
- Let the fries rest for 5 minutes before serving warm.

Notes
- Don’t skip any of the steps. You’ll want evenly cut taters, to soak, coat, flip, and rest before eating if you want crisp sweet potato fries.
- Don’t add salt until after baking the sweet potato fries (the salt draws out moisture and that won’t help them crisp).
- You can use arrowroot powder in place of cornstarch but it’s generally recommended that you need twice the amount.
- Sweet potato fries are perfect with some dipping sauce! Equal parts of ketchup, mayo, BBQ, hot sauce, and mustard makes a great dipping sauce.
- These fries don’t store well in the freezer or fridge so make what you need.
hai im from Indonesia, i really like this food, looks very good, it seems i have trouble finding food like this in indonesia
My favourite way of prepping fries. Soaking, oil and the cornstarch with seasonings are what make this recipe good. I do use an air fry tray in the oven instead of a sheet pan and I think it works even better.
Ohhh I love that idea, I bet it works great. I’ll have to find one of those trays!
Okay, these were AMAZING.
I do have one question though—how can I make them crunchier? Mine were very very soft. Almost mushy in some cases (didn’t stop my fiancé and I from eating the entire thing lol). Wondering if I should put the broiler on it maybe? Or more cornstarch? Hotter for longer? Thinner cut?
Any tips appreciated.
Thank you 🙂
Cutting them to a smaller size helps!
If the planets all align correctly, then maybe this recipe will work. I saw all the great reviews and expected a better outcome. The cornstarch was a disaster. I probably didn’t do everything as instructed but I will not be trying this recipe again.
i agree
I’ve made these a few times and they’re amazing- but I was wondering if there is a way to make them in bulk and freeze them for later, so we don’t have to cut and prep every time. Do you think that would work? Thanks!
I think the reheat is the issue. Do you have an air fryer? I feel like if you prepped, baked, froze in a single layer, bagged them up and frozen them and THEN did something like an air fryer, they just might reheat nicely (I swear my air fryer is magical for this kind of frozen potato product). I’m going to try this! If you do too, will you report back and let us know. It’s a fabulous idea.
