Refrigerator Instructions: Store in an airtight container in the refrigerator for up to three days. It's best to store it separately from any sauces or toppings you plan to serve it with to ensure it stays fresh. Freezer Instructions: First, let it cool completely and then place it in a single layer on a baking sheet. Put the baking sheet in the freezer until the falafel is frozen solid, then transfer the frozen patties to a freezer-safe container or bag and store for up to three months. Reheating Instructions: Bake in the oven at 350°F (175°C) for 10-12 minutes or until heated. Alternatively, you can heat it in the microwave for 30 seconds to 1 minute, depending on the strength of your microwave.
