Line two baking trays with aluminum foil and grease them with oil
Preheat the oven to 450 F.
Clean the sweet potatoes and peel the skin. Make uniform thin long cuts
out of the potatoes. Make sure the potatoes are evenly cut since this ensures even baking in the oven. Dry the sweet potatoes thoroughly and then place them in a bowl.
To the cut sweet potatoes, add all the listed ingredients and mix them
well using your hands. Ensure that the spices coat the sweet potatoes well.
Layer them in the prepared baking trays. Do not overcrowd them in the tray. Make sure the sweet potatoes are single layer and not one on top of another.
Bake them in the preheated 450 F oven for about 30 mins, turning them once
or twice in between.
Serve hot with ketchup!
Notes and Observations:
I add sugar to the fries, because it helps in better caramelization of
the potatoes. If preferred you could leave this out.
Also adding the spices to the fries is totally your choice. Add what you
like and omit the rest.
When turning the fries in between baking, make sure that you turn all the
fries. This way they cook uniformly, otherwise you might end up burning a
few in the bottom.
