Line baking tray with aluminum foil and parchment paper, or just parchment paper, but make sure it covers the entire tray.
Brush olive oil over the parchment paper.
In a small bowl combine the rest of the ingredients and slightly whisk. Pour this mixture over the potatoes and toss them around to make sure each wedge is fully coated in the spice.
Place the potatoes on the baking sheet and bake on the middle rack for 15 minutes. Take the tray out and turn wedges over and bake for another 10 or 15 minutes or until potatoes are done.
