Tools & Equipment Needed

Essential Equipment

• Large skillet
• 9×13-inch baking dish
• Aluminum foil
• Knife and cutting board
• Measuring cups and spoons
• Mixing spoon or spatula

Optional Helpful Tools

• Cheese grater for fresh cheese

Step-by-Step Instructions

1. Sauté the Vegetables

Heat a large skillet over medium heat. Add sliced onions and bell peppers. Cook until softened and fragrant, then remove from heat and set aside.

2. Prepare the Chicken

Season chicken pieces with fajita seasoning. In the same skillet, sear chicken for a few minutes on each side until lightly browned (it does not need to be fully cooked). Cut into bite-sized pieces if needed.

3. Assemble the Casserole

Preheat oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish. Spread uncooked rice evenly across the bottom.

4. Add Liquid and Ingredients

Pour chicken broth over the rice. Add seasoned chicken, sautéed vegetables, and optional beans, corn, or tomatoes. Stir gently to combine everything evenly.

5. Bake Covered

Cover the dish tightly with foil. Bake for 35–40 minutes, or until the rice is tender and the chicken is fully cooked.

6. Add Cheese and Finish Baking

Remove foil and sprinkle shredded cheese evenly over the top. Return to oven and bake uncovered for 5–10 minutes, until the cheese is melted and bubbly.

7. Serve

Let rest for a few minutes before serving so the casserole sets slightly.
