The casserole looks cheesy and slightly crispy on the edges. A silver spoon is placed inside the dish, scooping out a portion revealing the rice and beans underneath.

Ingredients

2½ cups uncooked rotini pasta
1 cup sour cream
1 cup salsa
1 packet mild taco seasoning
½ teaspoon cumin
½ teaspoon garlic powder
½ teaspoon onion powder
1 can (15 oz) corn, drained
1 can (15 oz) black beans, drained and rinsed
2½ cups cooked chicken
2 cups shredded cheese

Instructions

Step 1: Preheat your oven to 350°F (175°C). Prepare a 9×13-inch baking dish by spraying it with cooking spray and set it aside.
Step 2: Cook the rotini pasta according to the package instructions until al dente, adding about 1 teaspoon of salt to the boiling water for flavor.
Step 3: While the pasta cooks, combine the sour cream, salsa, taco seasoning, cumin, garlic powder, and onion powder in a large mixing bowl.
Step 4: Drain the pasta well (do not rinse) and add it directly to the sour cream mixture. Stir gently to combine, then fold in the corn, black beans, cooked chicken, and 1 cup of the shredded cheese.
Step 5: Pour the combined mixture into the prepared baking dish. Sprinkle the remaining 1 cup of shredded cheese evenly over the top. Cover the dish with tin foil and bake for 20 minutes.
Step 6: Remove the foil and bake uncovered for an additional 5 minutes to let the cheese brown slightly. Garnish with extras like sour cream, diced tomato, chopped cilantro, or avocado slices if desired before serving.

Tips & Variations

Use rotisserie chicken for a quick shortcut and extra flavor.
For added heat, swap mild taco seasoning for a spicy version or add finely chopped jalapeños.
Try mixing in other vegetables like diced bell peppers or cooked zucchini for more color and nutrition.
Swap black beans for pinto or kidney beans based on preference.

Storage

Store any leftovers in an airtight container in the refrigerator for 3 to 4 days. To reheat, warm the casserole in the oven at 350°F until heated through or microwave individual servings until hot, stirring halfway.

How to Serve

Mixed within the pasta are black beans, small red tomato pieces, and green herbs sprinkled over the top. A woman's hand is holding a metal spoon, scooping some of the pasta from the bowl. The bowl sits on a white marbled surface with a bit of a blue and white patterned cloth partially visible. The textures show the creamy sauce, soft pasta, and fresh vegetable pieces.

FAQs

Can I make this casserole ahead of time?

Yes, you can assemble the casserole up to a day in advance. Keep it covered in the refrigerator and bake it when you’re ready to serve, adding a few extra minutes to the baking time if it’s cold from the fridge.
