How to Make Chicken Fajita Rice Casserole

Step 1: Prepare the Chicken and Vegetables

Start by slicing the chicken into thin strips and chopping the bell peppers and onions into bite-sized pieces. Sauté the chicken in olive oil until cooked through, then add the vegetables and cook until they soften slightly, about 3 to 4 minutes, stirring regularly.

Step 2: Mix the Seasonings and Rice

In a large bowl, combine the uncooked rice with the fajita seasoning, then stir in the cooked chicken and veggies. Pour in the chicken broth and mix everything gently yet thoroughly so the flavors start to mingle.

Step 3: Assemble the Casserole

Transfer the rice mixture into a greased casserole dish, spreading it out evenly. Top the entire dish with a generous layer of shredded cheese to lock in moisture and add rich, creamy texture as it melts.

Step 4: Bake to Perfection

Cover the casserole with foil and bake in a preheated oven at 375°F (190°C) for about 40 minutes. Then remove the foil and bake for an additional 10 minutes or until the cheese is bubbly and golden on top.

Pro Tips for Making Chicken Fajita Rice Casserole

• Use fresh veggies: Fresh bell peppers and onions provide the best texture and flavor compared to frozen alternatives.
• Don’t over-stir rice: Avoid mixing after baking to keep the rice fluffy and not mushy.
• Cover while baking: Prevents the rice from drying out and ensures even cooking.
• Prep ingredients ahead: Cut veggies and cook chicken the night before to speed up assembly time.
• Adjust seasoning carefully: Taste your fajita seasoning mix prior to adding to avoid overpowering the dish.
