Ingredients

Why this recipe works

Using pre-cooked rotini pasta ensures the perfect texture in the final bake. Boiling the pasta just to al dente before mixing prevents it from becoming mushy or overcooked during the baking process. The pasta ridges are excellent at holding onto the creamy salsa sauce, ensuring that every single bite is packed with rich, savory flavor.

Baking the assembled casserole at a high temperature melts the cheese into a gooey, golden blanket while heating the chicken and vegetables thoroughly.

This process allows the flavors of the salsa, black beans, corn, and chicken to meld beautifully. The result is a cohesive dish with contrasting textures of tender pasta, juicy corn, and melted cheese.

Notes and substitutions

For the chicken, rotisserie chicken is an excellent time-saving option that adds great flavor. You can also use any leftover cooked chicken breasts or thighs.

If you prefer to cook the chicken fresh, ensure it is fully cooked and shredded before adding it to the pasta mixture. A Mexican cheese blend works beautifully here, but Cheddar or Monterey Jack are also fantastic alternatives.

Choosing a high-quality creamy salsa is key, as it provides both the moisture and the primary seasoning for the casserole.

If you cannot find creamy salsa, you can easily make your own by mixing regular tomato salsa with a bit of sour cream or softened cream cheese. Be sure to drain and rinse the black beans well to keep the sauce clean and bright.

• rotini pasta: penne or medium pasta shells work equally well to hold the creamy sauce.
• creamy salsa: mix 1 cup of regular salsa with 1/2 cup of sour cream or cream cheese.
