Step One: sauce part one

Start by preheating your oven to 375℉. Grease a 9×13 casserole dish with non-stick cooking spray or butter to ensure easy removal of the baked dish later.

Create the roux: In a 4-quart or larger Dutch oven, melt the butter over medium heat. Gradually stir in the all-purpose flour, making sure to cook and stir the mixture constantly for about 2 minutes to create a smooth roux that will thicken the sauce.

Step Two: sauce part two 😊

final stages of making cheese sauce.

Thicken the sauce: Slowly pour in the chicken stock while whisking continuously to combine it with the roux. Keep heating the mixture over medium heat, whisking constantly until the sauce thickens.

Add seasonings and vegetables: Incorporate the taco seasoning, oregano, garlic, salt, pepper, green chilies, and salsa into the thickened sauce. Keep stirring over medium heat until the mixture starts bubbling.

Stir in the cream: Add the heavy cream to the sauce and mix well, bringing the sauce back to a simmer.

Add the cheese: Lower the heat and gradually stir in 2 cups of Pepperjack cheese and 1 cup of Colby Jack cheese, making sure to keep stirring until all the cheese has melted and the sauce is smooth and creamy.

Step three: mix

🔍 FAQs

Can I use a store-bought rotisserie chicken instead of cooking the chicken myself?

Yes, I always do.

Is this recipe spicy?

No, unless you usse spicy salsa or the extra hot green chiles. For a spicier dish, choose hot taco seasoning and salsa, and consider adding more green chilies or even some diced jalapeños.

👩🏻‍🍳 Expert tips

  • When cooking the pasta, aim for an al dente texture, as it will continue to cook when baked in the casserole. Overcooked pasta will be mushy after baking.
  • Allow the baked casserole to rest for a few minutes after removing it from the oven. This helps the dish set and makes serving easier.
  • When adding cheese to the sauce, do so gradually and over low heat to ensure even melting and prevent the sauce from becoming grainy or clumpy.

    Excellent recipe to add to our favorite Mexican inspired dishes rotation.

    My only question was at what point would you recommend adding the shredded chicken? I swear I’ve read it through a few times and don’t see it.
