Creating these creamy spinach turkey meatballs is simple and rewarding. Follow these steps:

1. Preheat Oven: Preheat your oven to 400°F (200°C).
2. Mix Meatball Ingredients: In a large bowl, combine ground turkey, chopped spinach, breadcrumbs, Parmesan cheese, onion, garlic, beaten egg, Italian seasoning, salt, and pepper. Mix until well combined.
3. Form Meatballs: Shape the mixture into meatballs, about 1 inch in diameter, and place them on a baking sheet lined with parchment paper.
4. Bake Meatballs: Bake the meatballs in the preheated oven for 20-25 minutes, or until cooked through and browned.
5. Prepare the Sauce: While the meatballs are baking, heat olive oil in a skillet over medium heat. Add heavy cream, chicken broth, and crushed red pepper flakes (if using), stirring well to combine.
6. Simmer the Sauce: Bring the sauce to a gentle simmer, allowing it to thicken slightly while the meatballs finish cooking.
7. Combine Meatballs and Sauce: Once the meatballs are done, transfer them to the skillet with the creamy sauce. Gently coat each meatball with the sauce.
8. Heat Through: Let the meatballs simmer in the sauce for an additional 5 minutes, allowing the flavors to meld.
9. Garnish and Serve: Remove from heat and garnish with fresh parsley before serving.

Following these steps will lead you to a wonderful dish loaded with flavor and nutrients.
