Step 1

Preheat the oven to 350 degrees F. Spray a 7 x 12-inch baking dish with cooking spray.

Step 2

Cook the pasta in salted water as the package directs. Drain and place into a large bowl.

Step 3

Meanwhile, place the oil into a 10-inch skillet and heat over medium-high heat. Brown the chicken breasts on each side, about 5 minutes total.

Step 4

Add the Alfredo sauce, chilies, bell pepper, pepper flakes, and salt to the bowl with the pasta and toss to coat. Place the pasta mixture into the baking dish and tuck the chicken into the pasta, spooning a bit of sauce over the chicken and topping with the reserved red bell pepper.

Step 5

Bake for 30 to 45 minutes, depending on the size of the chicken breasts.
