Step 1Preheat your oven to 400 degrees F. Lightly grease a ceramic rimmed baking dish (such as a 9 X 13 -inch baking dish).Step 2Peel the jicama and cut it into 1/4-inch-thick fries. Or use pre-sliced jicama strips (available at Whole Foods and in many supermarkets).Step 3Place the jicama strips in a microwave-safe bowl. Add 1/4 cup water. Cover and microwave for 8 minutes, stopping once to gently stir. If I use a large jicama I sometimes microwave it for up to 10 minutes total, as shown in the video. But 8 minutes is usually enough.Step 4Using oven mittens, remove the bowl from the microwave. Be careful when removing the cover - hot steam will escape. Remove the jicama strips to paper towels to dry.Step 5In a large bowl, toss the partially-cooked jicama fries with the olive oil and the spices. Arrange them in a single layer in the prepared baking dish.Step 6Bake until browned and tender-crisp, about 40 minutes.
