Preheat your oven to 400°F and line a baking sheet with parchment paper for easy cleanup.
In a large mixing bowl, combine the ground turkey, egg, almond flour, dried oregano, garlic powder, onion powder, sea salt, and black pepper.
Gently mix the ingredients by hand until just combined, ensuring you do not overwork the meat to keep the texture light.
Roll the mixture into uniform 1.5-inch balls and arrange them evenly on the prepared baking sheet.
Lightly brush the tops of the meatballs with olive oil to help them develop a golden-brown crust while baking.
Bake for 15 to 18 minutes, or until the meatballs reach an internal temperature of 165°F.
While the meatballs bake, warm the marinara sauce in a medium skillet over low heat until it begins to simmer.
Carefully transfer the baked meatballs into the skillet, tossing gently to coat them in the sauce.
Garnish with freshly chopped parsley and serve warm as a protein-packed main dish.
