Helpful Tips for Chicken Fajita Casserole

The above recipe is my family's favorite way to prepare this casserole dish. There have been times that I have made slight adjustments due to being short on time, not having an ingredient on the list, or just playing around with this recipe to see which way is better. Here are a few helpful tips that may come in handy if you wish to try out this dish:

  • If you are running short on time, substitute a package of precooked seasoned chicken strips from the freezer. This kind of chicken will save you 20 minutes of cooking time.
  • If you are out of any of the spices listed above in the ingredients, use a package of fajita or taco seasoning mix to replace all the spices. Both of these mixes work great in this recipe.
  • If you prefer more tender vegetables in your fajitas, sauté the green peppers and onions for a few minutes before adding them to this casserole dish.
  • If you don't have fresh veggies on hand, substitute a bag of frozen stir-fry vegetables. Make sure to completely thaw the bag before adding in these vegetables.

Family Meal Ideas for the Leftovers

When we make this delicious casserole recipe, we usually have 5 to 6 servings left in the baking dish. Instead of just serving the same meal later on in the week, try one of these ideas for how to serve your family chicken fajita casserole leftovers:

  • Chicken Fajita Nachos: Warm up the casserole in the oven. Spread tortilla chips over a large platter and add the casserole on top of the chips. Add additional toppings such as black olives, sour cream, salsa, and jalapenos.
  • Chicken Fajita Tostadas: Heat up the casserole and tostada shells in the oven. Add a serving of the chicken fajita casserole inside the tostada shell. Top with lettuce, tomatoes, and sour cream.
  • Chicken Fajitas over Mexican Rice: Prepare a package of Mexican rice on the stovetop while reheating the casserole in the oven. Pour a serving of rice on a plate and top with casserole leftovers. Add any desired toppings to complete the dish.

I hope I have tempted you enough to try out this delicious and easy-to-make chicken fajita casserole dish. It has quickly become one of our family's favorite meals. In addition to being so tasty, I love this casserole because I can quickly throw together a second Mexican-inspired meal in no time which comes in handy with our busy schedule.
