Jambalaya can be stored in an airtight container in the fridge for 3-4 days. To reheat it, you can warm it in the microwave or in a skillet on the stovetop. Just spread the leftover jambalaya out in a skillet and heat over medium heat. Stir it frequently so it doesn’t burn on or dry out too much. If it starts to dry out while you reheat it, add a splash of water or chicken broth. Be careful not to heat it for too long as the shrimp will overcook and get tough.  To freeze jambalaya, let it cool completely in the fridge and then place it in a freezer-safe container and store in the freezer for up to 3 months. Let the jambalaya defrost in the fridge before reheating it.
