Storage & Reheating Tips

Proper Storage

This chicken fajita casserole is one of those foods with chicken that keeps beautifully, making it perfect for meal prep. Once cooled completely, cover the casserole dish with plastic wrap or aluminum foil, or transfer leftovers to airtight containers. Refrigerate for up to 3-4 days. For longer storage, you can freeze individual portions in freezer-safe containers for up to 2-3 months. When freezing, I recommend cutting the casserole into portions first and wrapping each one separately in plastic wrap before placing in freezer bags. This makes it easier to thaw only what you need for simple yummy dinners later in the month.

Best Reheating Methods

To maintain the wonderful texture and flavors of your chicken fajita casserole when reheating, there are several approaches. For refrigerated leftovers, reheat in a 350°F oven for about 15-20 minutes until heated through. Cover with foil to prevent the top from burning. Alternatively, microwave individual portions for 1-2 minutes, stopping halfway to stir if possible. For frozen portions, thaw overnight in the refrigerator before reheating, or use the defrost function on your microwave followed by regular heating. Add a sprinkle of fresh cheese on top before reheating to refresh the melty, gooey topping. A few drops of water before covering can help prevent the casserole from drying out during reheating.
