01 - Preheat the oven to 400°F and line a baking sheet with parchment paper.
02 - In a large bowl, mix ground turkey, breadcrumbs, Parmesan, egg, garlic, parsley, oregano, salt, and black pepper until just blended.
03 - Shape the mixture into 16 to 18 equal meatballs and arrange them evenly on the prepared baking sheet.
04 - Bake the meatballs for 15 to 18 minutes until they are lightly browned and fully cooked.
05 - While meatballs bake, heat olive oil over medium heat in a skillet. Sauté chopped onion until soft, about 3 to 4 minutes, then add garlic and cook for 1 minute.
06 - Add roasted red peppers, chicken broth, smoked paprika, chili flakes (if using), salt, and pepper. Simmer the mixture for 5 minutes.
07 - Transfer the sauce to a blender or use an immersion blender to puree until completely smooth.
08 - Return the pureed sauce to the skillet, stir in heavy cream, and bring to a gentle simmer.
09 - Add the baked meatballs to the sauce and simmer for 5 to 7 minutes, spooning sauce over them to ensure even coating.
10 - Sprinkle with fresh basil or parsley and serve while hot.
