Notes
Ravioli: If using frozen ravioli, allow a few extra minutes of cooking time.Pasta: Cook the pasta in salted water to flavor the pasta itself. Cheese: Use freshly grated cheese for the best melting quality and best flavor.Sauce consistency: For a richer sauce, omit the chicken broth and double the amount of heavy cream called for in the recipe.Storage and reheating: Refrigerate leftovers for up to 3 days. Reheat slowly over low heat to prevent the sauce from breaking.
