Season chicken breasts with salt, pepper, garlic powder, and Italian seasoning. Heat olive oil in a large skillet over medium-high heat.
Add chicken to the skillet and cook for 5-7 minutes per side, or until golden brown and cooked through. Remove chicken from skillet and set aside.
In the same skillet, add minced garlic and sun-dried tomatoes. Cook for 1-2 minutes, or until fragrant.
Pour in chicken broth and heavy cream. Bring to a simmer and stir in spinach, red pepper flakes, salt, and pepper.
Allow the sauce to simmer for 5-10 minutes, or until slightly thickened. Return the cooked chicken to the skillet and coat with the sauce.
Cook pasta according to package directions. Drain and add to the skillet with the chicken and sauce. Toss to combine.
Serve immediately, garnished with grated Parmesan cheese and fresh basil leaves, if desired.
