Yes, you can definitely freeze vegan lentil meatballs. They freeze well, making them a convenient option for meal prep or quick and easy meals. To freeze vegan lentil meatballs, allow them to cool completely to room temperature. Once they have cooled, place them in a single layer of parchment paper and put them in the freezer for about an hour. This technique will prevent them from sticking together when you put them in a container or freezer bag. Once the lentil meatballs are totally or partially frozen, transfer them to an airtight container or freezer bag. Label the container or bag with the date and contents, and then store it in the freezer for up to 3 months. To thaw the lentil meatballs, simply transfer them from the freezer to the refrigerator and allow them to thaw overnight. You can also reheat them in the oven, microwave, or on the stove. Enjoy your Turkish vegan meatballs!
