Perfect Oven Sweet Potato Fries

Step 5Baking!

Baking!
Put them in the oven for 15 minutes. Do not open the oven or fidget with them during this time. Just let 'em cook. The smell will probably be too much to bear, so perhaps this is a good time to go to another room and focus on something else. :D

Then, take them out and flip them. I use my bare hands most of the time, but tongs work well too.

Once they're flipped, put them back in the oven for 10 minutes. :)

Both sides should now be dark brown and crispy and delicious. And hopefully spicy, if you followed my directions. Spicy is the way to go with sweet potato fries!

Keep in mind that I like mine REALLY dark and crispy. Should you want a lighter brown color, just reduce the cooking time a couple minutes for both sides.

Enjoy! :D

Additional cooking tips:
  • these will not turn out very crispy at all if you're cooking anything else in the oven, or if the fries are crowded too close together. They'll sweat instead of crisp!
  • keep an eye on them because ovens are tricksy little things. You don't want them to get black.
  • also, a lighter colored baking sheet is preferable - mine are very dark and I've started to have to cut my cooking time a lot to avoid getting them too dark.

Yummy! Crispy outside and mushy inside. Delish! Goes really well with leftover tzatziki sauce from last night. Thanks for great recipe!

Nice detail and humor in your instructions! I'm going to try this tonight :) I've always done my "French Fries" this way, but love the idea of trying it with sweet potatoes!

MorganCrane, a kumara IS a sweet potato! Kumara is the Maori word for the exact same veggie. The Oceanic peoples have been growing sweet potatoes for centuries, if not millennia--it is a staple food in much of the Pacific region and no doubt the Maoris brought them to NZ. I am in New Zealand right now and can find red, orange and white kumaras, all tasty.

Another terminological note: In the U.S., where I live most of the year, groceries often call sweet potatoes, particularly the orange ones, 'yams'. But the yam is a different root vegetable, native to Africa. It's starchier, less sweet, and (usually) larger. I see them in the U.S. only in African markets--yams are a staple food of sub-saharan Africa. In my opinion they're not as tasty as sweet potatoes--or at least, you need to do more to them to make them appetizing.

The sweet potato fries recipe is great!! Or rather, baked kumara chips as I believe they would be called here.

Yeh, great recipe and almost as good as kumara chips in NZ (unsurpassable). My kiwi spouse has heard they're a perfect accompaniment to "pakeha" (white man)-- and with 2 veg you have a complete meal--ha!--but generally kiwis prefer lamb to pakeha.

I make a dip from sour cream with a little horseradish for a kick. It's great. Thanks for sharing your recipe!

You could also try making my amazing One Minute Mayonaise with horseradish or wasabi. Chipolte and Garlic or a straight up chilli mayo would be epic with these as well.

Thanks for the instructable.. very easy to follow.
I made them and the whole family enjoyed them!

Thanks for your clear and easy directions. I have two aging sweet potatoes that were begging for the baking sheet rather than the compost bucket. You saved them. Yummy.

Could you apply the olive oil by tossing oil onto the sliced sweet potatoes in a mixing bowl? (Rather than drizzle all over the baking sheet?)

Could you perch some cooling racks inside a cookie sheet, and place the pieces atop, in order to avoid the turning-over operation (air flow beneath) ?

I can't wait to bake these for Thanksgiving.

Very nice! The favorite dip to go along with these in my house is a few chopped chipotle peppers mixed into some mayo, the tangy, spicy dip compliments the sweet, salty fries really well

OMG! I am going to walk to the store to make these things RIGHT NOW!!!

I just roasted sweet potato wedges the other day in a very similar fashion, and they were delicious! 

The crowning touch was a drizzle of balsamic vinegar syrup (just boil 1 cup of vinegar until it reduces to 1/4 cup & store in the fridge) ... SO good.

I would imagine the addition of some chili powder to these would be really tasty, too!

I've enjoyed sweet potatoes and regular spud fries on the barby grilled in a perforated tray made for small items but you have raised the science to an art form.  Thank you for sharing your hard won knowledge and expertise.  I like to have a plate with ketchup, mustard, salt and pepper in separate piles to dip the delectable morsels into as you wish.  Very professional presentation and perfectly cooked, in my humble opinion.  Cheers!

I have a similar recipe with regular spuds in which I leave the peel on as I like the flavour and it adds some valuable nutrients to them. Is there a reason to peel the sweet potato (ie toxic, or foul tasting) or could I get away with leaving the peel on?

I used rosemary, lemon pepper, sea salt and fresh ground pepper... they were great, evev my 19 year old liked them!

There is no reason not to leave the skins on the sweet potatoes.. Not only does it add flavor, nutrients and texture it helps in keeping the soft potato together. The only time I peel my sweet or white potato is if there is a hard spot or blemish. I tend to cut mine into wedges... and roast on. Quick and easy... and oh so satisfying.

We tried it.... great. My wife adds a little cayenne pepper.

You're killing me! I have to go make this NOW.

I first discovered these in New Zealand, there is a sweet potato like veggie called Kumara, and they are often made into Kumara chips. Now the trend has spread to the US, but this treat will always remind me of my past life in New Zealand!
