Ingredients

• Red or Green Bell Peppers, Sliced – Add vibrant color, natural sweetness, and a crisp texture while providing vitamin C and antioxidants.
• Large Purple Onion, Sliced – Brings a mild sweetness and slight bite, enhancing flavor complexity and offering heart-healthy flavonoids.
• Dry White Rice, Rinsed and Drained (uncooked rice)– Acts as a hearty base, soaking up flavors while providing a comforting source of energy.
• Chicken Bone Broth – Deepens the dish’s savory richness and keeps the rice tender while supplying collagen and minerals.
• Lemon Pepper Fajita Seasoning (Siete Brand) – Infuses bold, zesty warmth with a balanced mix of spices that also offer anti-inflammatory benefits.
• Chicken Breast – Provides a lean, juicy protein that absorbs the seasoning well and keeps the casserole satisfying.
• Cheddar Cheese, Shredded – Melts into a creamy, savory topping that ties everything together while adding calcium and protein.

Garnish with:

• Cilantro – Lends a fresh, herbaceous brightness that complements the rich, warm flavors.
• Lime – Enhances the dish with a tangy contrast that balances the savory and spicy notes.
• Low Fat Plain Greek Yogurt/Light Sour Cream – Adds a cool, creamy element that tempers the spices and boosts gut-friendly probiotics.

Instructions

1. Pre-heat your oven to 375 F and set your rack to the middle position.
2. Slice your bell peppers and onions.
3. Place white rice into a 9x13 casserole dish. Add your chicken bone broth over the rice. Next, add in your chicken breasts into an even layer on top. Using about half of your lemon pepper fajita seasoning, evenly season your chicken breasts. Then add in your sliced bell peppers and onions evenly on top of your seasoned chicken and then use the remaining packet and season your vegetables evenly on top.
4. Cover your casserole dish with foil and bake for 50 minutes or until your chicken has reached an internal temperature of 165 F, your vegetables are soft and your rice is cooked through.
5. Remove your casserole dish from the oven. Be careful not to burn yourself. Top with freshly grated cheddar cheese and then broil for 1-2 minutes until your cheese is melted and slightly browned.
6. Serve and then garnish with cilantro, lime and low fat greek yogurt or light sour cream.

Hint: I do not use olive oil in this recipe, but if you would like to add some healthy fats, feel free to add a drizzle before baking.

Substitutions

• Red Onion - use regular white or yellow onion if you don't have any red onions.
• Siete Lemon Pepper Fajita Seasoning- Feel free to use your favorite fajita seasoning instead or make your own homemade fajita seasoning but please look for added fillers to make sure that the product is gluten-free/dairy-free if you follow a specific diet.
• White Rice- feel free to substitute white rice for brown rice but please keep in mind that this can delay cooking time. I have not personally tried this recipe with brown rice. You can also use instant rice for this recipe as well.
• Chicken Bone Broth- I use chicken bone broth for collagen and additional micronutrients but feel free to use chicken broth or chicken stock instead for this recipe
• Chicken- If you're not a fan of raw chicken, you can also use rotisserie chicken for this meal.
• Dairy-Free- Skip the cheddar cheese and low fat greek yogurt/light sour cream to make this recipe dairy-free.

This chicken fajita casserole recipe with rice is already gluten-free as is.

Variations

• Spicy - add red chili pepper flakes, green chiles and serve with your favorite hot sauce to make this recipe spicy. Also feel free to add some chili powder as well.
• Lower Sodium- feel free to use less seasoning or make your own to make this dish lower in sodium.
• More veggies- Feel free to add cauliflower rice and black beans to add additional fiber and nutrients to this dish!
