To prepare a gluten-free version of this dish, substitute the regular pasta with a gluten-free alternative such as rice-based penne or chickpea pasta. Be sure to check the labels of the chicken broth, sun-dried tomatoes, and parmesan cheese to confirm they are gluten-free and free from cross-contamination. Adjust the cooking time slightly, as gluten-free pasta may cook faster or become softer than wheat-based varieties. Stir gently to prevent breakage.
