1-How to Prepare the Perfect Fajita Chicken Casserole: Getting this Fajita Chicken Casserole on the table is straightforward and fun, folks. Start by preheating your oven to 350°F and giving a 9×13 inch baking dish a quick spray with nonstick cooking spray. It’s all about making sure everything cooks up just right without any sticking.

2-Mix Ingredients: In a large bowl, mix together the shredded cooked chicken, uncooked instant rice, cream of chicken soup, sour cream, frozen diced onion and bell pepper blend, undrained diced tomatoes with chilies, chicken broth, fajita seasoning, and half of the shredded Mexican blend cheese. Pour this mix evenly into your prepared dish and cover it tightly with aluminum foil. Pop it in the oven and bake for 35 to 45 minutes until the rice is tender.

3-Finish Baking: Once that’s done, take off the foil, sprinkle on the rest of the cheese, and bake a bit more until it melts just right. Let it sit for a minute before serving to keep everything nice and hot. This whole process takes about 10 minutes to prep and 35-45 minutes to cook, for a total time around 55 minutes.

4-First Steps: Prep and Mix: Preheat your oven to 375°F (190°C). Slice the chicken and vegetables thinly. In a large skillet, cook the sliced chicken with half the fajita seasoning until browned, then set aside.

5-Middle Steps: Sauté and Layer: Sauté the onions and bell peppers in the same skillet with the remaining seasoning. Combine everything in a bowl, layer it in the dish, and add the tortillas if using.

6-Final Bake: Cover and bake for 20 minutes, then uncover and bake another 10 minutes. For the best results, use tips like adding extra broth if things look dry.
