Preheat the oven to 425 degrees F. Lightly coat a piece of parchment paper with non-stick spray and place on a baking sheet.
Remove excess water in shredded zucchini by wrapping it in a clean kitchen towel. Wring or squeeze until zucchini is really dry.
In a medium bowl, add zucchini, egg, onion, cheddar cheese, panko bread crumbs and spices together.
Scoop tablespoons of zucchini mixture onto the prepared baking sheet. Press mounds together to form a football-like shape and lightly flattened.
Bake for 16-20 minutes until the edges are golden.
Serve immediately with ranch dressing, if desired.
