In a large mixing bowl, thoroughly combine the ground turkey, almond flour, grated Parmesan cheese, egg, minced garlic, chopped parsley, onion powder, dried oregano, and a pinch of salt and black pepper. Use your hands or a spatula to ensure that all the ingredients are evenly mixed.
Set your oven to preheat at 400°F (200°C), allowing it to heat up while you prepare the meatballs.
With clean hands, take about 2 tablespoons of the meat mixture and roll it into a ball, aiming for a size of roughly 1.5 inches in diameter. You should yield around 12-15 meatballs from the mixture.
In a large oven-safe skillet, heat the olive oil over medium heat. Once hot, add the meatballs in batches (if necessary) to avoid overcrowding. Sear the meatballs for about 3-4 minutes on each side until they are golden brown all over.
Carefully pour the sugar-free marinara sauce over the browned meatballs in the skillet. Use a spoon to gently coat each meatball in sauce so they are well covered.
Transfer the skillet to the preheated oven. Bake for 15-20 minutes, or until the meatballs reach an internal temperature of 165°F (74°C) and are cooked through.
After baking, remove the skillet from the oven and allow the meatballs to rest for a few minutes. This helps them retain their juices and stay flavorful.
Notes
Serve with spiralized zucchini noodles or a green salad for a complete keto meal.
