There is no substitute for lemongrass, but you can leave it out and the recipe will still taste good. Lemongrass does have a slightly citrusy taste, so you might add a little lime juice to the mix.

We've been baking SP wedges for years. We microwave the wedges before any infusion to cook the inside and speed up the oven time (thickness determines oven time).
Sweet potatoes go from caramelized to charred very quickly - look at the photo here!
There are ways to make SPs crisp like french fries using various coatings (egg white, etc) but it's time consuming, not suited for a weeknight.
SPs are very nutritious, with much lower glycemic index than potatoes.

Anyone have a suggestion for what to use instead of lemongrass if that is not available? Thanks!
Nico
it will be hard to make them crispy like french fries if that's what you are after. They will be charred, which is not caramelized - you would send them back if a restaurant served them to you this way. Use about 400+ convection, and a short cooking time. Watch them very carefully. Turn them 3-4 times if you can.
A double-layered baking pan with an air gap in between may temper the heat somewhat to prevent them from charring so fast.
They have great taste on their own or with just cumin.

These are delicious, but the other commentators are right, they do not get crisp like french fries. There's also no reason that I can see to strain your ginger lemongrass infusion. I crush up the cumin and coriander seeds in the mortar with the other stuff, and after the oil is heated a bit, I just dump it on the potatoes and toss without straining, and it's even more flavorful this way.

All time family favorite. I have to make 2 batches as my son and daughter will leave very little for my wife and me!

A dusting of corn starch, skip the parchment, and a preheated pan will help create a crispier crust. They still won't be like French Fries but they're a bit more satisfying.
SS
Higher temp, maybe. Wanted more crispy bits.
Beth Gahbler
One of our absolute favorite recipes. I have made it twice with the oil infusion and once without when I had less time. Always exellent.

By accident I discovered that soaking the potatoes in cold water up to two days really changes how these fries turn out. After soaking dry with a towel snd then spice up snd toss in olive oil. The heat can also be turned up to 450F with a 20-25 cook time.
Jo
Substituted freshly squeezed lime at the end since I didn't have lemongrass. This is a heavenly sweet potato dish.
Imbrod
Procedure was good, but the ginger-lemon grass-infused oil added nothing.

I make sweet potato fries all the time with just a tablespoon of evoo, salt and pepper. I bake them at 200c for 30 minutes or until carmelized without turning. They are delicious. I’ll will try tossing in the coriander and cumin seeds with a bit more oil but I won’t go to al the fuss of the ginger and lemon grass.
Gary johnson
I used a few strips of lemon zest - very satisfactory.
Sunny
The potatoes turned out very soft but not carmelized; more like baked than fried. Tasty, but not what I was looking for.

With these ingredients, this recipe delivers great flavor. Really easy, healthy, and vegan. I bought pre-minced lemongrass and ginger pastes to shorten step #1. I'm sure it's even better with fresh ingredients.
Alex
Great recipe!!! Short of time, I skipped the first step - grated the lemongrass (and ginger) very finely, mixed with olive oil, cumin, salt & pepper, then tossed the sweet potato slices in that. 1/4 to 1/3 thick slices worked well.
Gaby
For me it needed an extra kick so next time I'll double the cumin or maybe add cayenne pepper. Also I'll make sure the pieces are thiner cause the big pieces didn't cook as well I would've liked to.

Sanaz
Evan, you mean dusting sweet potato wedges before tossing with oil?
Steve
I don't see any parchment paper in the photo. Perhaps that is how she achieved the crispness. I'll give that a try.
Petaltown
Even in the photo, they don't look crisp. I've never achieved crispness in sweet potatoes cooked this way--they're still very tasty, but not crisp. Parchment paper wouldn't help. Another commenter mentioned coatings, such as egg white. That's what you need to get them crisp.
