Pasta & Sauce
- 2½ cups uncooked rotini pasta
- 1 cup sour cream
- 1 cup salsa
- 1 packet mild taco seasoning
- ½ teaspoon ground cumin
- ½ teaspoon garlic powder
- ½ teaspoon onion powder
Vegetables & Protein
- 1 can (15 oz) corn, drained
- 1 can (15 oz) black beans, drained and rinsed
- 2½ cups cooked chicken, shredded or chopped
Dairy
- 2 cups shredded cheese (cheddar or Mexican blend recommended)
- Preheat and Prepare: Heat your oven to 350°F (175°C). Lightly spray a 9×13 inch baking dish with cooking spray and set it aside for later use.
- Cook Pasta: Boil the rotini pasta in salted water (about 1 teaspoon salt) until al dente according to package instructions. Drain the pasta but do not rinse it to retain starch for better sauce adherence.
- Mix Sauce: In a large mixing bowl, combine the sour cream, salsa, taco seasoning, cumin, garlic powder, and onion powder. Stir until evenly mixed to create a flavorful sauce.
- Combine Ingredients: Add the drained pasta into the sauce mixture and stir well to coat. Then fold in the drained corn, rinsed black beans, cooked chicken, and 1 cup of shredded cheese, mixing everything thoroughly.
- Assemble Casserole: Transfer the mixture to the prepared baking dish and evenly spread it out. Sprinkle the remaining 1 cup of shredded cheese over the top to create a cheesy crust.
- Bake Covered: Cover the casserole with aluminum foil and bake in the preheated oven for 20 minutes, allowing everything to meld and heat through.
- Bake Uncovered: Remove the foil and bake for an additional 5 minutes to melt and slightly brown the cheese topping.
- Garnish and Serve: Optionally garnish with extra sour cream, diced tomato, chopped cilantro, and avocado slices before serving. Store leftovers covered in the refrigerator for 3-4 days.
Notes
- Use mild taco seasoning for a balanced flavor, or substitute with medium/hot for more spice.
- Salt the pasta water well to enhance the overall dish seasoning.
- Do not rinse the pasta after cooking to help the sauce stick better.
- Leftovers keep well refrigerated for up to 3-4 days, making this dish suitable for meal prepping.
- Optional garnishes like avocado and cilantro add freshness and texture contrast.
