Step 1

Preheat the oven to 400F/200C/gas mark 6. Line two baking sheets with parchment paper. Put the oven rack in the top third of the oven if your heating element is at the bottom of your ovn, or in the middle if the heat comes from above.

Step 2

Scrub the sweet potatoes, lightly dry, then cut into rustic fries. Cut off any bruises or bad spots.

Step 3

Toss the fries in a large bowl with the olive oil, making sure they are completely coated.

Step 4

Mix all the spices together in a small bowl until one color.

Step 5

Sprinkle the spice mixture over the sweet potatoes, stirring and tossing with a large spoon, adding more until the fries are evenly coated with spices.

Step 6

Pour the fries onto the prepared sheets, making sure they are not touching each other.

Step 7

Bake for 10 minutes, stir, then bake another 10-15 minutes until the fries are crispy on the outside and soft inside when pierced with a fork. Serve with your favorite mayo as a dipping sauce.
