Begin by boiling water in a large pot for the pasta. Be sure to lightly salt the water.Once pasta water is boiling, add the pasta and stir well while it cooks. Meanwhile, in a large skillet over medium-high heat, pour in the 2 tablespoons of olive oil. Place the chicken breasts in the pan and cook for 5-6 minutes on each side until cooked through. Once chicken is cooked, remove from pan onto a cutting board and lightly salt the chicken..Slice into bite-sized pieces. Set aside. Once pasta is cooked through, strain and put into a large bowl with 2 tablespoons of butter. Toss to coat well, to ensure the pasta doesn't stick. Set aside.
In a large skillet over medium heat, add in the sun-dried tomatoes (with oil), plus the 2 tablespoons of garlic. Sautee for 3-4 minutes until fragrant. Stir constantly so the garlic doesn't burn. Once fragrant, add in the heavy cream and the fresh grate parmesan. Mix well and continue to cook over medium heat until a creamy sauce forms. Add 1/2 teaspoon salt and 1/4 teaspoon red pepper flakes.
Pour the creamy sauce over the pasta. Then add in the chicken and the fresh basil. Toss to combine.
Serve warm and top with additional fresh basil if desired. Enjoy!
