Colorful Oven Fries

Serves 6

Oven-fried sweet potatoes can be tricky because the potatoes’ high moisture content makes it difficult for them to “fry,” and their ample sugar causes them to burn easily. Okinawan sweet potatoes work well here because of their dry texture, but a dusting of potato starch helps keep all varieties crisp.
  • 2 lb. assorted sweet potatoes, peeled and cut into ¼-inch-thick sticks
  • 1 Tbs. canola oil
  • ½ tsp. salt
  • ½ tsp. ground black pepper
  • ¼ tsp. ground cinnamon, optional
  • 2 Tbs. potato starch

1. Preheat oven to 450°F. Line 2 baking sheets with parchment paper, or coat with cooking spray. Set 1 oven rack in top position and 1 rack in bottom position.

2. Toss together sweet potatoes, oil, salt, pepper, and cinnamon, if using. Sprinkle with potato starch; toss mixture once more to coat well. Arrange in single layer on prepared baking sheets. Bake 10 minutes.

3. Turn potatoes with spatula, and rotate baking sheets. Bake 12 minutes more, or until golden brown.

These sweet potato fries have been the absolute favorite of my family! Thank you for this wonderful recipe that turns out perfectly each time.

This turned out well, but didn't stay crispy long. I let the fries cool in the pan for awhile before transferring them to a serving dish. I like more cinnamon flavor so the second time I made this, I doubled the amound of ground cinnamon which was perfect for my taste. I'm thinking that the potato starch may not necessary since the fries will become soggy after sitting out for awhile, but it still tastes delicious. (The potato starch also adds 80 extra calories to the entire recipe.) I accompany my fries with a spicy red pepper hummus which was a perfect combination with my fries. I will make this again, but the potato starch is not an essential ingredient.

I didn't have sweet potatoes on hand, so I just used a bunch of different varieties of potatoes -- red, purple, fingerlings, etc. I added crushed garlic to the oil and coarse sea salt. Omitted the cinnamon. Mine weren't getting crispy enough, so I left them in the oven for another 5 minutes, with the oven turned off. That did the trick -- they were awesome and crispy. Served them with a buffalo dipping sauce made of vegannaise and Frank's. Everyone loved these, and I'll definitely make again.

The easiest way to slice a sweet potato is by using a mandolin slicer. They can be picked up cheap at any kitchen goods store or Target. Just be careful when you get down to the bottom, use the hand attachment so as not to slice yourself.

You could use tapioca starch as a substitute for potato starch. If you have a Whole Foods or other health food store near you they are likely to carry both, or Bob's Red Mill online as someone else suggested. An Indian grocery store would also have potato starch.

If anyone is hunting for potato starch you can sometimes find it in the kosher section of the grocery store. It's easier to find in the spring time closer to Passover because the potato starch and flours are sold as substitutes for wheat.

I was wondering if there was something we could do with green bananas to get similar crisp chips.....

We avoid oil as much as possible. Does anyone know a way to made these without using oil at all? Thanks.

I found the potato starch gave the potatoes have a pasty texture.

Sweet potatoes are difficult to cut and I cut them round too. I have not thought about using potato starch does make a different. Thanks

Octavia - 2010-06-26 18:36:09

I cut mine in rounds (because for me it's a lot easier than wedges or fries), toss with a little olive oil and either soy sauce or balsamic vinegar, sometimes with a little chili powder mixed in, then toss a little rosemary on top after they're on the pan. These are addicting

Sweet potatoes cook so much better and crisp better on the outside if you parboil them and then bake them or fry in peanut oil.

Aren't sweet potatoes difficult to cut? How do you cut them into slices or rounds? I always have to bake them a little before I can cut through them. Wouldn't this change the cooking time? Am I the only wimp that can't easily cut through raw yams / sweet potatoes?

I made these today and they were DELISH! I didn't even use the potato starch. ;-)

Natrina - 2010-03-18 23:39:05

I've made these before, but instead of 'tossing together' or 'sprinkling' the ingredients onto the fries, once the sweet potatoes are cut, I put all the ingredients (including the potatoes) into a large plastic bag and shake them around. Seems to more evenly coat everything. I haven't used potato starch before, but in this case, I would probably shake the potatoes in the bag with the starch first, then add the other ingredients and shake again. Sort of shake 'n' bake--? :-)
