Preheat oven to 400 degrees and line rimmed baking sheet with parchment paper.
Peel and slice jicama into 1/4-inch matchsticks.
Add matchsticks to saucepan. Cover with an inch of water. Add 3/4 teaspoons of salt. Bring water to a boil. Boil for 10 minutes.
While jicama is boiling, combine spices.
Drain jicama in colander and lay on paper towels to dry.
Put olive oil in mixing bowl. Add jicama and toss to coat. Sprinkle on seasonings and toss to coat.
Lay jicama sticks in single layer on lined baking sheet. Bake for 20 minutes, flip, then bake for 20 more minutes until tender-crisp and golden brown.
Remove from oven, let cool for a couple of minutes, and enjoy!
Instead of boiling, can microwave jicama with a microwave-safe bowl covered with cling wrap or a plate for 8-10 minutes. Remove carefully - the bowl will be hot and will release steam!
