Tips
Fridge:
Leftovers will keep in the refrigerator for two days or so. Just wrap the baking dish tightly in aluminum foil or plastic wrap, or transfer leftovers to an airtight container.
Freezer:
If you have more leftovers than you know what to do with, store them in a freezer safe container with a layer of plastic wrap on top. Thaw in the fridge overnight before reheating, or reheat from frozen.
For best results, reheat leftovers in the oven. However, you can reheat enchiladas in the microwave they just likely will be a bit soggy.
The sauce will thicken up when it’s chilled and won’t be as creamy. When you reheat, it should thin out but there may not be as much sauce as when it is fresh.
