This one started as a happy accident — a customer once bought my Quesadilla Lasagna because he loved combining Mexican and Italian food, and it hit me that I had another mashup just waiting to happen. Fajita chicken, Mexican seasoning, and pepper jack folded into a cheesy baked pasta turned out to be exactly that.

I first made this as a special at Krafty Draft Brew Pub, and after sneaking a bite of the leftovers while portioning it into containers, I understood immediately why my husband and kids kept begging me to make it a regular. It graduated from experiment to menu staple fast.

Ingredients

  • 1 lb. fajita-style cooked chicken, cut into bite-size pieces
  • 1 lb. small pasta shells (use GF pasta to make this gluten-free)
  • 1/2 cup unsalted butter
  • 1/2 cup all-purpose flour (use GF all-purpose flour to make this gluten-free)
  • 3 tablespoons All-Purpose Mexican Seasoning (or taco seasoning)
  • 4 1/2 cups whole milk
  • 1 lb. pepper jack cheese, shredded
  • 1 lb. sharp cheddar cheese, shredded, plus more for topping

Instructions

  1. 1Preheat oven to 350 degrees.
  2. 2Cook the pasta according to package directions for the minimum time listed, then drain and set aside.
  3. 3Melt the butter in a pot over medium heat. Whisk in the flour and cook for 1 minute, then whisk in the Mexican seasoning.
  4. 4Slowly whisk in the milk, working out any flour clumps. Continue cooking over medium heat for about 10 minutes, whisking occasionally, until the sauce has thickened.
  5. 5Remove from heat and stir in the cheeses until melted.
  6. 6Add the chicken and pasta, stirring well, then pour into a greased 9x13-inch baking dish (it will be full). Sprinkle a little extra cheddar on top.
  7. 7Bake for 25-30 minutes. Let sit for about 5 minutes before serving.
