Set your oven to 375°F. Move the rack to the upper section. Cover a baking sheet with parchment paper.

Combine chicken, egg, panko, half the Parmesan, Italian seasoning, garlic powder, onion powder, salt and pepper in a big bowl. Blend thoroughly and shape into 1-inch balls. If they're too sticky, put a little olive oil on your hands.

Warm olive oil in an oven-safe pan over medium-high heat. Cook meatballs in small groups until they're brown all over, roughly 5 minutes. Put them on a plate when done.
04 -
Take the pan off the heat and scrape up any stuck bits. Pour out extra oil, but keep those tasty brown bits for flavor.
05 -
Add marinara to the pan, drop in the meatballs, and scatter the leftover Parmesan and all the mozzarella on top.
06 -
Bake for 15 minutes or until meatballs reach 165°F inside.

If you want, broil for 2 minutes to make the cheese golden brown. Serve hot and dig in!
