In fact, preparing the sauce ahead of time can help save you time and also help you get dinner on the table fast. Prepare the sauce as mentioned in the recipe and remove it from the heat without adding the pasta. Allow it to cool completely at room temperature, and transfer it into an airtight container before transferring it to the refrigerator for up to 3-4 days. When you're ready to use the sauce, gently reheat it on the stovetop over low to medium heat, stirring occasionally until heated through. Toss in the cooked pasta and you have dinner on the table in a flash. You may need to add a little bit of water or broth to adjust the consistency.
