01 - Heat olive oil in a large skillet over medium heat. Add the crumbled turkey sausage and cook, stirring occasionally, until browned and fully cooked, about 5 to 6 minutes.
02 - Add finely chopped onion to the skillet and cook until softened, approximately 3 minutes. Stir in minced garlic and sauté for an additional minute until fragrant.
03 - Incorporate the chopped kale and cook, stirring frequently, until wilted, about 2 minutes.
04 - Add the potato gnocchi, heavy cream, and chicken broth to the skillet. Stir to combine, then bring the mixture to a gentle simmer. Cover and cook for 4 to 5 minutes, stirring occasionally, until the gnocchi are tender and cooked through.
05 - Remove the lid, stir in grated Parmesan cheese, then season with salt, black pepper, and red pepper flakes if desired. Adjust consistency by adding additional broth or cream if the sauce is too thick.
06 - Plate immediately and garnish with extra Parmesan cheese and freshly chopped parsley if preferred.
