Preheat oven to 400°F and line a baking sheet with parchment.

Grate zucchini and wrap in a clean towel, squeezing out as much moisture as possible.

Combine ground meat, squeezed zucchini, Parmesan, egg, garlic, Italian seasoning, onion powder, salt, and pepper and mix until just combined.

Roll into 1.5-inch balls and place on the prepared sheet.

Bake for 20-22 minutes until golden and cooked through.

Serve with marinara or pesto for dipping.
