A Weeknight Casserole That’s Healthy and Satisfying
The Story Behind This Casserole
This recipe came together on a cold evening when I had a few pantry staples and no plan. I tossed together some rice, salsa, a can of beans, corn, and chicken—then baked it all together with some seasoning and cheese. The result? A bold, cheesy casserole with warm Southwestern spices and a whole lot of comfort.
It tasted like something you’d find in a restaurant, but it was all made in one dish, with no pre-cooking and no fancy ingredients. The rice baked perfectly under all the salsa and broth. The chicken stayed juicy. And the cheese pulled it all together.
Why It’s a Healthy Dinner Choice
This Southwest chicken casserole (healthy!) doesn’t rely on processed ingredients or heavy sauces. It’s built from:

Step-by-Step Guide to Southwest Chicken Casserole
Simple Ingredients, Bold Flavor
The best part about this Southwest chicken casserole (healthy!) is how easy it is to prep. You don’t need to cook anything beforehand. Everything goes into one dish, and the oven does the work for you.
What you’ll need:
- Protein: Boneless skinless chicken breasts
- Grains: Long grain white rice
- Veggies: Onion, garlic, corn, black beans
- Flavor: Salsa, chili powder, paprika
- Binder: Chicken broth
- Finish: Shredded cheddar cheese
Everything is easy to find and budget-friendly. The salsa does most of the heavy lifting when it comes to flavor, so use one you really like.
How to Assemble and Bake It Right
1. Preheat the oven to 350°F so it’s ready by the time you finish prep.
2. Layer the base.
In a 12×9-inch casserole dish, add uncooked white rice, garlic, onion, and chicken broth. Stir it gently so the rice stays mostly on the bottom.
3. Add the main ingredients.
Layer on cubed raw chicken, rinsed black beans, defrosted corn, and salsa. Sprinkle chili powder and paprika evenly over the top.
4. Add cheese.
Sprinkle shredded cheddar cheese over everything. You can use more or less, depending on how cheesy you want it.
5. Bake covered.
Cover with foil and bake for 45 minutes. This steams the rice and helps it cook evenly.
6. Uncover and finish.
Remove the foil and bake for another 10 minutes to melt the cheese and get a golden top.
7. Rest and serve.
Let the casserole sit for 5 to 10 minutes before scooping. This gives the rice a chance to firm up and the flavors to settle.
This method ensures the rice is fully cooked without burning, the chicken stays juicy, and the whole dish has a warm, bold Southwestern flavor.
Easy Customizations and Healthy Swaps
Make It Work for Any Diet
One of the best things about this Southwest chicken casserole (healthy!) is how adaptable it is. You can make small changes without losing the core flavor or texture.
Want it dairy-free?
Omit the cheese or use a plant-based shredded cheese. You can also top the casserole with diced avocado or a drizzle of dairy-free yogurt after baking for creaminess without dairy.
Need to lower the carbs?
Replace the rice with cauliflower rice. Because cauliflower rice cooks much faster than white rice, reduce the baking time to about 30 minutes total and check for doneness early.
Prefer brown rice?
Use long grain brown rice, but increase the chicken broth slightly and extend the baking time by about 10 to 15 minutes to make sure it cooks through.
Gluten-free by default.
All the ingredients are naturally gluten-free, so no changes are needed unless using pre-packaged salsa or broth. Double-check those labels if necessary.
Add More Flavor or Veggies
If you love bold flavors or want to sneak in more vegetables, try one of these easy additions:
- Peppers: Add diced red or green bell peppers for extra crunch and color.
- Zucchini or spinach: Stir in finely chopped zucchini or a handful of baby spinach before baking. They’ll soften and blend right into the mix.
- Toppings after baking: Chopped cilantro, lime wedges, diced avocado, or green onions add freshness and color after it’s baked.
You can also spice it up with a little hot sauce or extra chili powder if you prefer more heat.
