Chicken Fajita Casserole is the perfect quick and easy weeknight meal. Made in one dish this effortless meal comes together so quickly and packs tons of fiesta flavor. Eat it on its on our stuff it in tacos, burritos, or quesadillas.

Chicken fajita casserole is a dish the whole family can enjoy. I mean one dish is a busy mama’s dream, so delicious and easy cleanup. My kids arent crazy for large cut veggies so I will usually slice theirs up super fine before serving. However, hubby and I love this as is, we cleared out plates. Generally, I like to serve it with rice, or cauliflower rice for myself.

I love this chicken fajita casserole for leftovers too. It tastes so delicious in a tortilla!

How To Make Chicken Fajita Cassarole

You can take a short cut and buy thinly sliced chicken breasts, I like to save a few dollars and buy the whole breast and slice them in half at home.
