Ingredients
  

  • 2 cups cooked rotini pasta or any short pasta like penne or fusilli
  • 2 cups cooked chicken shredded (leftover or rotisserie chicken works great)
  • 1 cup Alfredo sauce store-bought or homemade
  • 1 cup salsa mild or spicy, your choice
  • 1 cup black beans drained and rinsed
  • 1 cup corn frozen and thawed or canned, drained
  • 1 cup shredded Mexican cheese blend
  • 1/2 teaspoon ground cumin
  • 1/2 teaspoon chili powder
  • 1/4 teaspoon garlic powder
  • Fresh cilantro for garnish optional

Substitutions:

  • Use Greek yogurt mixed with a bit of Parmesan in place of Alfredo sauce for a lighter option.
  • Swap black beans for pinto beans if desired.
  • Add diced bell peppers or green onions for extra crunch and color.

Instructions
 

Preheat the oven and prepare your baking dish

  • Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish with cooking spray or a bit of oil.
  • Tip: Greasing the dish makes cleanup a breeze and prevents sticking.

Mix the sauce base

  • In a large mixing bowl, combine the Alfredo sauce and salsa. Stir until well blended. Add the cumin, chili powder, and garlic powder.
  • Tip: Mixing the spices into the sauce ensures even flavor distribution.

Combine the main ingredients

  • Add the cooked pasta, shredded chicken, black beans, and corn into the sauce mixture. Stir everything together until evenly coated.
  • Tip: Make sure the pasta and chicken are fully coated to keep the casserole moist and flavorful.

Transfer to the baking dish and top with cheese

  • Pour the mixture into the prepared baking dish and spread it out evenly. Sprinkle the shredded cheese blend over the top.
  • Tip: For extra golden cheesy goodness, use a mix of Monterey Jack and cheddar.

Bake until bubbly

  • Bake uncovered for 20-25 minutes, or until the cheese is melted and bubbly and the casserole is heated through.
  • Tip: Let it sit for 5-10 minutes before serving so the sauce thickens slightly.

Garnish and serve

  • Sprinkle fresh chopped cilantro over the top before serving, if desired.
  • Tip: Serve with a dollop of sour cream or a few slices of avocado for a creamy finish.

Notes

No Alfredo sauce? Make a quick version with butter, cream, and Parmesan.
Want more veggies? Add chopped spinach, bell peppers, or zucchini.
Making ahead? Assemble and refrigerate for up to 24 hours before baking.
Don’t overbake or the pasta may dry out. Cover with foil if needed during baking.
