Absolutely! Having the pomodoro sauce prepared in advance allows you to save time and enjoy the convenience of having a flavorful base ready for your Chicken Pomodoro whenever you need it. Here's how to do it: Follow the recipe for the pomodoro sauce as directed, starting from step 3, sautéing the onions and garlic. Complete the sauce, then allow the pomodoro sauce to cool. Transfer it to an airtight container or a jar with a tight-fitting lid, making sure to leave some space at the top for expansion if you plan on freezing it. It can be stored in the fridge for up to 4-5 days or in the freezer for up to 3-4 months. When you're ready to use the sauce, remove it from the refrigerator or thaw it in the freezer. If frozen, thaw the sauce overnight in the refrigerator. Once thawed, sear the chicken breasts as directed, then add the completed sauce to the pan and scrape up the browned bits. Add the chicken breasts back to the pan to complete cooking, then enjoy!
