In a large mixing bowl, gather your ground turkey, breadcrumbs, egg, finely chopped onion, minced garlic, and Parmesan cheese. Season the mixture with salt and pepper and blend the ingredients.

Gently combine the ingredients until just mixed, ensuring a uniform texture without overworking the mixture.

Scoop out portions of the mixture and roll into balls about 1.5 inches in diameter, placing them on a parchment-lined baking sheet.

Preheat your oven to 350°F (180°C) and bake the meatballs for 10-15 minutes until golden brown and slightly crisped on the edges.

Check the internal temperature using a meat thermometer; ensure they reach 165°F (74°C) for safe consumption.

Let the meatballs cool slightly before serving. They can be paired with pasta, rice, or steamed vegetables.
