01 - Preheat oven to 400°F. Line a baking sheet with parchment paper or lightly grease with olive oil.
02 - In a large bowl, combine ground turkey, panko, Parmesan, egg, milk, parsley, basil, thyme, garlic, grated onion, salt, pepper, and oregano. Mix gently until just combined to ensure tender meatballs.
03 - With damp hands or a small scoop, form the mixture into 1- to 1.5-inch meatballs, about 20 in total, and place evenly on the prepared baking sheet.
04 - Lightly drizzle or brush the meatballs with olive oil to promote browning during roasting.
05 - Roast in the preheated oven for 20 to 25 minutes, turning once halfway through, until golden brown and cooked through with an internal temperature of 165°F.
06 - Serve immediately with your choice of sauce, over pasta, or alongside a fresh salad.
