Preheat your oven to 400°F (200°C).

In a large mixing bowl, combine the ground turkey, large egg, salt, black pepper, minced garlic, and chopped parsley until well combined.

Lightly oil your hands and roll the turkey mixture into quarter-sized meatballs, about 15 total.

Heat a skillet over medium-high heat and sear the meatballs for 2-3 minutes on each side until browned.

Lower the heat and add butter, then stir in heavy cream, Parmesan cheese, garlic powder, salt, and black pepper. Simmer for about 5 minutes.

Carefully place the browned meatballs back into the skillet with the creamy sauce, then transfer to the oven and bake for 15 minutes.

Remove from the oven, garnish with parsley and additional Parmesan, and serve hot.
