With your hands, combine the ground chicken, almond flour, parmesan, eggs, salt, pepper, oregano, and parsley in a large bowl.
Scoop out 2 tablespoons of the mixture and flatten it in your hand. Place a mozzarella ball in the center and bring the meatball mixture up around to completely enclose the meatball. Roll it to make a uniform ball shape. Continue with the rest of the meatball mixture and set aside on a plate.
Preheat the oven to 350F
Heat a heavy bottom skillet over medium heat and add the olive oil. Once the oil is hot, add half of the meatballs and brown on all sides. Remove to a plate and add the remaining meatballs to the skillet to brown.
Remove all meatballs from the skillet and pour in the marinara sauce. Whisk to combine the marinara sauce with the remaining olive oil. Add the meatballs on top of the marinara sauce and place in the oven to bake for 15 minutes.
Remove the skillet from the oven and garnish with parmesan if desired. Serve.
