Begin by bringing a large pot of water to a boil, ensuring it's generously salted. Once boiling, add your linguine or fettuccine and cook according to the package directions until al dente. Once done, drain the pasta and set it aside, reserving a small cup of the pasta water in case you need to loosen the sauce later.
In a large skillet, heat the olive oil over medium heat. Once hot, add the ground turkey along with the Cajun seasoning, salt, and freshly cracked black pepper. Cook while stirring occasionally for about 5-7 minutes, or until the turkey is browned and completely cooked through. Remove the turkey from the skillet and place it in a bowl, setting it aside for later.
In the same skillet where you cooked the turkey, add the diced bell pepper and chopped onion. Sauté the vegetables for approximately 3-4 minutes, or until they begin to soften. Next, add the minced garlic and continue to sauté for an additional minute, or until fragrant.
Carefully pour in the chicken broth and bring the mixture to a gentle simmer. Once simmering, add the heavy cream and cherry tomatoes, stirring well to combine. Allow the sauce to simmer for about 5 minutes, enabling it to thicken slightly.
Return the cooked turkey to the skillet along with the fresh spinach. Stir everything together until the spinach wilts down and all ingredients are well incorporated. Taste the mixture, adjusting the seasoning with more salt and pepper if necessary.
Add the drained pasta to the skillet, tossing it with the turkey and vegetable mixture until everything is evenly coated. If the sauce seems too thick, add some of the reserved pasta water a little at a time to achieve your desired consistency. Cook for an additional 2-3 minutes to ensure everything is heated through.
Portion the pasta onto individual plates or bowls. Finish each serving with a generous sprinkle of grated Parmesan cheese and a garnish of fresh chopped parsley for a burst of color and flavor.
Notes
Pair with crusty garlic bread and a light green salad for a complete meal.
