I have to tell you, this Southwest Chicken Casserole Recipe has become one of my favorite go-to meals. I first tried it on a busy weeknight, and I was blown away by how flavorful and comforting it was. The creamy sauce, tender chicken, and spicy kick make it a perfect dinner for the whole family.
I love that it’s simple to throw together, but tastes like it took hours to make. Every time I serve it, people keep asking for seconds—and I don’t mind at all! You can also enjoy similar dishes like Honey Garlic Chicken Recipe for a sweet-savory twist on chicken meals.

Ingredients
Here’s what you’ll need to make this delicious casserole. I’ve added a few tips to help you get the best results.
- 2 cups cooked chicken, shredded – I like rotisserie chicken for convenience, but leftover baked chicken works just as well. You could also try a flavorful One Pot Cajun Chicken Pasta Recipe as another easy chicken dinner option.
- 1 can (15 oz) black beans, drained and rinsed – Adds protein and texture; rinsing removes excess sodium.
- 1 can (15 oz) corn, drained – Fresh or frozen corn gives a sweeter, fresher taste.
- 1 cup diced red bell pepper – Adds vibrant color and a crisp, sweet flavor.
- 1 cup diced green bell pepper – Complements red peppers for visual appeal and flavor balance.
- 1 small onion, finely chopped – Provides savory depth to the casserole.
- 2 cups cooked rice – I use long-grain white rice, but brown rice works for a healthier version.
- 1 can (10 oz) diced tomatoes with green chilies, drained – Offers a subtle kick without overpowering the dish.
- 1 cup shredded cheddar cheese – Grating fresh cheese ensures a melty, gooey texture.
- 1 cup shredded Monterey Jack cheese – Adds creaminess and balances the cheddar’s sharpness.
- 1 cup sour cream – Keeps the casserole rich and creamy.
- 1 packet taco seasoning – I prefer homemade for more control over spice and salt.
- 1/2 teaspoon garlic powder – Enhances flavor without being too strong.
Note: Serves 6–8 people.

I love experimenting with this casserole. Here are some tweaks you can try:

- Low-carb: Replace rice with cauliflower rice for a lighter version.
- Extra spice: Add jalapeños or a dash of cayenne for more heat.
- Flavor boosters: Mix in chopped cilantro or a squeeze of lime before serving.

How to Make Southwest Chicken Casserole Recipe
Step 1: Preheat Oven and Prepare Ingredients
I always preheat my oven to 350°F while chopping vegetables and shredding the chicken. This saves time and ensures the casserole cooks evenly. Preparing everything first makes the assembly quick and stress-free.
Step 2: Mix the Base
In a large bowl, I combine the chicken, rice, beans, corn, peppers, onion, diced tomatoes, and taco seasoning. I stir everything until it’s evenly coated so every bite has balanced flavor.
Step 3: Add Creaminess
Next, I fold in the sour cream and half of the cheese. This gives the casserole a creamy, rich texture. Make sure it’s evenly mixed so the cheese melts throughout.
Step 4: Assemble in Baking Dish
I spread the mixture into a greased baking dish, smoothing the top with a spatula. Then I sprinkle the remaining cheese over the top for a golden, melty finish.
Step 5: Bake
I bake it uncovered for 20–25 minutes until the cheese is bubbly and slightly browned. The aroma alone makes me excited to dig in!
Step 6: Serve
Once out of the oven, I let it sit for 5 minutes before serving. This helps it set slightly so it’s easier to portion out.
Additional Tips for Making This Recipe Better
From my experience, a few tweaks can make this even more delicious:
- I like to toast the rice slightly before mixing to enhance the flavor.
- Adding a bit of lime juice at the end brightens up the flavors.
- Using a mix of cheeses gives a more complex, creamy texture.
- I sprinkle a little paprika on top for color and mild smokiness.
How to Serve Southwest Chicken Casserole Recipe
I love serving this straight from the baking dish for a cozy, homey vibe. You can also plate it with a garnish of fresh cilantro, a dollop of sour cream, or a few sliced avocado pieces. It pairs perfectly with a simple green salad or tortilla chips on the side.

Make Ahead and Storage

Reheating
I reheat individual portions in the microwave or the whole dish in the oven at 350°F for 15–20 minutes until heated through. The cheese melts beautifully again.
