How to Make Chicken Fajita Rice Casserole

Step 1: Prepare the Ingredients

Start by slicing the chicken into strips, dicing the bell peppers, and chopping the onion. This prep ensures everything cooks evenly and your casserole gets layered with colorful textures and flavors.

Step 2: Sauté the Chicken and Vegetables

Heat olive oil in a large skillet over medium-high heat and cook the chicken strips until just browned. Add the onions and bell peppers and sauté until tender but still vibrant, stirring in the fajita seasoning halfway through to coat everything in that signature spice blend.

Step 3: Combine Rice and Broth

In a mixing bowl, combine cooked rice with the chicken broth to keep the casserole moist and flavorful. Then gently fold in the sautéed chicken and vegetables, mixing everything together evenly.

Step 4: Assemble the Casserole

Transfer the chicken, pepper, and rice mixture into a greased casserole dish. Top with a generous layer of shredded cheese to add richness and a gooey texture as it bakes.

Step 5: Bake and Serve

Bake the casserole at 375°F (190°C) for about 20-25 minutes, or until the cheese is bubbly and slightly golden. Let it rest for a few minutes, then serve hot and enjoy the melty, zesty goodness.

Pro Tips for Making Chicken Fajita Rice Casserole

• Cook rice ahead: Use leftover or pre-cooked rice to speed up the cooking process.
• Don’t overcook veggies: Sauté peppers and onions just until tender-crisp to keep their vibrant color and texture.
• Even seasoning: Toss chicken and veggies with fajita seasoning before cooking for uniform flavor.
• Cheese layering: Add some cheese inside the mixture as well as on top for extra creaminess throughout.
• Let it rest: Allow the casserole to cool slightly before serving so it sets properly and slices nicely.
