This make-ahead chicken tetrazzini recipe features al dente ziti, perfectly browned chicken, and a rich, creamy sauce with mushrooms, cauliflower, and green chilies. It's designed for convenience, allowing prep in advance and baking just before serving, yielding a comforting and flavorful baked pasta dish for a crowd.
1. Achieving al dente pasta is crucial; it finishes cooking in the oven, preventing a mushy texture. 2. Ensure chicken breasts are fully browned for maximum flavor development from the Maillard reaction, but avoid overcooking them as they will continue to cook in the oven. 3. When building the sauce, allow vegetables to soften thoroughly to release their flavors, and ensure the flour is fully incorporated before adding liquids to prevent lumps. 4. Room temperature cream cheese will emulsify smoothly into the sauce, creating a velvety texture. 5. If making ahead and refrigerating, allow the dish to sit at room temperature for 30 minutes before baking to promote even heating, and add a splash of chicken broth or water if the mixture seems too thick after chilling.
