Refrigerate leftovers in an airtight container and they’ll stay tasty for about 3 to 4 days. Freeze portions in meal-sized containers with a tight lid to keep that broth depth from drying out. Reheat in the microwave or oven by warming slowly to keep the tender pull and cheese texture intact. Refresh leftovers with a sprinkle of cheese on top before reheating to get a little freshness back.
