Remove the skin from the cassava with a vegetable peeler or sharp knife. Slice the cassava in half lengthwise, then cut those halves in half lengthwise to make sticks.
In a large pot, cover the cassava slices with water. Heat over high heat. Bring to a boil and cook 8-10 minutes, or until fork tender.
Preheat the oven to 450 degrees F.
Drain the cassava sticks and gently rinse them with cold water. Transfer them to a paper towel and pat dry.
On a baking sheet, toss the cassava sticks with the olive oil, garlic powder, paprika, and salt and pepper. Arrange in a single layer, leaving space between each stick to avoid overcrowding.
Put the baking sheet to oven and bake for 30 minutes, carefully flipping halfway through until golden brown.
Serve warm with your favorite dip.
