You get tender chicken, fluffy rice, colorful veggies, and just enough cheese to feel special without weighing you down.

What Makes This Recipe So Good

• Taco night twist: Familiar taco seasoning, salsa, and corn give it that crowd-pleasing flavor without the mess of assembling tacos.
• One-pan friendly: Cook the aromatics, assemble, and bake. Fewer dishes, less stress.
• Flexible ingredients: Use brown or white rice, mild or hot salsa, and any beans you like.
• Great for leftovers: It reheats well and makes a solid meal-prep lunch.

What You’ll Need

• 1 pound boneless, skinless chicken breasts, cut into small bite-size pieces
• 1 tablespoon olive oil (plus more as needed)
• 1 small yellow onion, finely diced
• 1 red bell pepper, diced
• 2 cloves garlic, minced
• 1 cup long-grain brown rice (or white rice; see notes in Pitfalls section)
• 1 1/2 cups low-sodium chicken broth
• 1 cup tomato salsa (mild, medium, or hot)
• 1 (15-ounce) can black beans, drained and rinsed
• 1 cup corn kernels (frozen or canned and drained)
• 1 packet (about 1 ounce) taco seasoning or 3 tablespoons homemade
• 1/2 teaspoon kosher salt, plus more to taste
• 1/4 teaspoon black pepper
• 3/4 cup shredded Mexican-blend cheese (or reduced-fat cheddar)
• 1/4 cup chopped fresh cilantro (optional)
• Juice of 1/2 lime, plus wedges for serving
• Optional toppings: diced avocado, Greek yogurt or light sour cream, sliced jalapeños, extra salsa

Instructions

1. Preheat the oven: Set to 375°F (190°C). Lightly grease a 9×13-inch baking dish or similar casserole pan.
2. Sauté aromatics: Heat olive oil in a large skillet over medium heat.

   Add onion and bell pepper. Cook 4–5 minutes until softened. Stir in garlic and cook 30 seconds until fragrant.

3. Season the chicken: Pat chicken dry.

   Toss with half the taco seasoning, a pinch of salt, and pepper.

4. Brown the chicken: Push veggies to the side of the skillet. Add a drizzle of oil if needed. Add chicken and sear 3–4 minutes, stirring once or twice, until lightly browned but not fully cooked.
5. Combine base ingredients: In a large bowl, stir together rice, chicken broth, salsa, remaining taco seasoning, black beans, corn, and the sautéed chicken and veggies.

   Taste the liquid; add salt if needed.

6. Assemble: Pour the mixture into the prepared baking dish. Cover tightly with foil to trap steam.
7. Bake: For brown rice, bake 50–60 minutes; for white rice, bake 35–40 minutes. The rice should be tender and most liquid absorbed.
8. Add cheese: Remove foil, sprinkle cheese evenly on top, and bake uncovered 5–8 minutes more until melted and bubbly.
9. Finish and rest: Let the casserole sit 5 minutes.

   Squeeze lime juice over the top and sprinkle with cilantro.

10. Serve: Scoop into bowls and add optional toppings like avocado, Greek yogurt, or jalapeños. Serve with lime wedges.

Storage Instructions

• Fridge: Cool completely, then store in an airtight container for up to 4 days.
• Freezer: Portion into freezer-safe containers and freeze up to 3 months. For best texture, thaw overnight in the fridge.
• Reheating: Microwave individual portions 1–2 minutes, stirring halfway.

  For larger amounts, reheat covered in a 325°F oven until warmed through. Add a splash of broth if it seems dry.

Why This is Good for You

• Lean protein: Chicken breast delivers high-quality protein without a lot of saturated fat.
• Fiber-rich carbs: Brown rice and black beans pack fiber to keep you full and steady your energy.
• Veggie boost: Onion, bell pepper, corn, and salsa bring vitamins, minerals, and antioxidants.
• Smarter toppings: Greek yogurt stands in for sour cream, adding protein and creaminess without extra heaviness.
• Portion-friendly: Built-in portions make it easier to stick to a balanced plate.

Pitfalls to Watch Out For

• Rice choice matters: Brown rice needs more time than white. If using white long-grain, check early at 30–35 minutes.

  For parboiled or instant rice, reduce liquid and time significantly, or it may go mushy.

• Too much liquid: Salsas vary. If your salsa is very watery, reduce broth by 1/4 cup to prevent sogginess.
• Undercooked rice spots: Make sure the mixture is evenly spread in the dish and tightly covered. Steam is what cooks the rice.
• Overcooked chicken: Don’t fully cook the chicken on the stove.

  A quick sear is enough; it will finish baking in the casserole.

• Salt balance: Taco seasoning and broth vary in sodium. Taste the liquid before baking and adjust salt lightly.

Recipe Variations

• Extra-lean swap: Use ground chicken or turkey instead of diced chicken. Brown fully before mixing with the rice.
• Cauliflower rice: For a low-carb version, use 4 cups cauliflower rice and reduce broth to 3/4 cup.

  Bake uncovered for 20–25 minutes, since cauli rice releases moisture and cooks fast.

• Cheese-light: Cut cheese to 1/2 cup or skip it. Add a dollop of Greek yogurt on top for creaminess.
• Veggie-loaded: Stir in diced zucchini or spinach. If using spinach, fold it in right before baking so it just wilts.
• Spice level: Add chipotle powder or diced jalapeños for heat, or stick with mild salsa for a family-friendly version.
• Dairy-free: Use a dairy-free cheese or omit cheese and finish with avocado and extra salsa.
• Slow cooker: Combine everything except cheese in a slow cooker.

  Cook on High 2–3 hours with white rice or 3–4 hours with brown rice, stirring once. Top with cheese at the end to melt.

FAQ

Can I use rotisserie chicken?

Yes. Shred about 3 cups of cooked chicken and skip the browning step.

Mix it in with the rice, veggies, and liquids, then bake as directed. Reduce salt slightly since rotisserie chicken can be seasoned.

What kind of salsa works best?

A chunky, medium-thick salsa works well. If yours is very thin, reduce the broth a bit to keep the casserole from getting soupy.

Choose your spice level based on preference.

Can I make this ahead?

Yes. Assemble everything up through step 6, cover tightly, and refrigerate up to 24 hours. Add 5–10 extra minutes to the baking time since it will start cold.

How do I keep the rice from getting mushy?

Use long-grain rice, measure liquid carefully, and keep the foil sealed during baking.

Check for doneness right at the minimum time to avoid overshooting.

Is there a gluten-free option?

This recipe is naturally gluten-free as long as your taco seasoning and broth are labeled gluten-free. Always double-check ingredient labels.

What if I don’t like black beans?

Swap with pinto beans, kidney beans, or leave them out and add more corn or diced zucchini for texture.

Can I add more protein?

Yes. Stir in 1/2 cup of plain Greek yogurt after baking for a creamy, higher-protein finish, or top with extra chicken from meal prep.
