Cajun Chicken Pasta
16 oz. fettuccine noodles
3 tablespoons olive oil, divided
2-3 boneless, skinless chicken breasts (1 pound)
2-3 teaspoons Cajun seasoning, divided*
1/2 teaspoon salt
1/4 teaspoon pepper
1/8 teaspoon cayenne pepper (optional)*
1 red bell pepper, thinly sliced
1 yellow or orange bell pepper (or half of each), thinly sliced
1/2 large red onion, sliced
Sun-dried Tomato Alfredo Sauce
2 tablespoons oil from sun-dried tomatoes in oil jar
1/2 cup sun-dried tomato halves, drained and finely chopped
4-6 garlic cloves, minced
2 tablespoons all purpose flour
2 cups low sodium chicken broth
1 1/2 cups milk (I use lowfat)
1 tbps each cornstarch and tomato paste
1/2 tsp each Cajun seasoning and salt
1/4 teaspoon pepper
2 oz. 1/3 less fat cream cheese, cubed, softened
3/4 cup freshly grated Parmesan
Freshly squeezed lime juice (highly recommended)
Fresh parsley
Cayenne pepper to taste
Cook fettuccine in salted water according to package directions just until al dente. Reserve 1/3 cup pasta water then strain and set aside.
Chicken: In a small bowl, mix 2-3 teaspoons Cajun seasoning, 1/2 teaspoon salt, 1/4 teaspoon pepper, 1/8 teaspoon cayenne pepper (optional) with 1 tablespoon olive oil and rub evenly all over chicken breasts. Let chicken sit while you prepare your vegetables OR refrigerate up to overnight.
Heat one tablespoon olive oil in a large non-stick skillet over medium high heat. Once very hot, add chicken and cook, undisturbed for 3-5 minutes, or until nicely browned (or blackened if you prefer) on one side. Turn chicken over, cover, and reduce heat to medium. Cook for approximately 5-7 more minutes (depending on thickness of chicken), or until chicken is cooked through. Remove to a cutting board and let rest at least 5 minutes before slicing.
Peppers: Add enough olive oil to remaining oil in pan to equal 1 tablespoon olive oil. Heat over medium high heat. Add peppers, onions and 1/2 teaspoon Cajun seasoning and saute for one minute. Remove to a plate.
