Cajun Sausage Shrimp Alfredo Pasta

Featured in: Weeknight Dinners

This flavorful one-pan skillet brings together smoky andouille sausage, tender shrimp, and aromatic vegetables tossed with penne pasta in a lush Cajun Alfredo sauce. Cajun seasoning enriches the creamy sauce, providing a gently spicy kick balanced by Parmesan cheese and fresh parsley. Simple steps call for sautéing sausage and shrimp separately, then building a rich sauce in the same skillet, ensuring everything melds together perfectly. Quick to prepare, this dish makes for an impressive weeknight main, especially when served hot with salad and garlic bread. For variations, swap sausage types or use gluten-free pasta. Ideal for those seeking a hearty, comforting meal with a Southern twist.
