Step 1: Prep and Organize Your Ingredients

Before you turn on the stove, take a moment to gather and prep all your ingredients. This little bit of upfront organization is a total game changer and makes the rest of the process a breeze.

• Slice your onion and the red, green, and yellow bell peppers into thin strips.
• Cut the chicken breasts or thighs into bite-sized pieces.
• If you’re using canned corn, black beans, or tomatoes, go ahead and drain them now.
• Measure out your rice and chicken broth so they’re ready to go.

Step 2: Sauté the Vegetables

Heat a large skillet over medium heat and drizzle in a tablespoon of olive oil. Once the pan is warm, toss in your sliced onions and bell peppers. Sauté for about 5–7 minutes, stirring occasionally, until they’re soft and slightly caramelized.

This step brings out the natural sweetness of the veggies and gives your casserole that classic fajita flavor base. Don’t skip it—it adds a big punch of taste!

Pro tip: If you’re short on time, you can substitute frozen pepper stir-fry mix, though fresh peppers will give you the best texture and flavor.

Step 3: Season and Sear the Chicken

Using the same skillet (because fewer dishes = more joy), add your chopped chicken and sprinkle it generously with fajita seasoning. Stir everything so the spices coat the chicken evenly. Let the chicken cook for about 3–4 minutes per side—just enough to get some browning.

No need to fully cook it here. The chicken will finish baking in the oven, soaking up all those juicy flavors from the rice and broth.

Step 4: Assemble the Casserole in the Baking Dish

Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with nonstick spray or a touch of olive oil. Spread the uncooked rice evenly across the bottom of the dish—yes, uncooked! This saves time and keeps things simple.

Now layer in your sautéed veggies and seasoned chicken. Pour the chicken broth over everything, and if you’re adding corn, black beans, or diced tomatoes, mix them in now.

Give the whole dish a gentle stir to make sure the rice is evenly distributed and submerged in the liquid. This helps everything cook evenly without any dry or crunchy bits.

Step 5: Cover and Bake Until Tender

Cover the dish tightly with foil—this traps the steam and helps the rice cook evenly. Bake for 35–40 minutes. You’ll know it’s ready when the rice is tender and the chicken is cooked through. No need to stir or check on it during baking; just let it do its thing.

Tip: If you’re using brown rice, you may need to bake it for an additional 5–10 minutes. Add a bit more broth if needed to avoid dryness.

Step 6: Add Cheese and Finish Baking

After the initial bake, remove the foil carefully (watch out for the steam!), and sprinkle the shredded cheese generously over the top of the casserole. Return it to the oven, uncovered, and bake for another 5–10 minutes.

You’re looking for that dreamy, melted cheese layer that’s bubbly and slightly golden around the edges. Once it’s looking irresistible, pull it out and let it rest for 5 minutes before serving. This helps the rice settle and keeps the servings nice and neat.

Key Tips for Making Easy Chicken Fajita Rice Casserole

4. Want it spicier? Add a dash of hot sauce or chopped jalapeños.
5. Meal prep queen? Divide into containers after baking—it stores like a dream.
6. Cheese choice matters—go for sharp cheddar or a melty Mexican blend for best results.

Storage and Reheating Tips for Easy Chicken Fajita Rice Casserole

This casserole is just as tasty the next day, maybe even more so. Store any leftovers in an airtight container in the fridge for up to 4 days. To reheat, you can microwave it (just splash a little broth or water to keep it moist) or pop it in a 350°F oven covered for about 15–20 minutes. Want to freeze it? Cool it completely, wrap it tight in foil, and freeze for up to 2 months. When ready to eat, thaw overnight in the fridge, then reheat as usual. It’s your secret weapon for lazy nights or surprise guests.
