Cook the Pasta – Bring a large pot of salted water to a boil and cook the fettuccine until al dente. Drain and set aside.
Sauté the Chicken – Heat olive oil in a large skillet over medium heat. Season the sliced chicken with garlic powder, Italian seasoning, salt, and black pepper. Cook for 5-7 minutes until golden brown and cooked through. Remove from the pan and set aside.
Prepare the Sauce – In the same skillet, add the minced garlic and sun-dried tomatoes. Sauté for 1 minute until fragrant. Pour in the heavy cream and chicken broth, stirring to combine. Let the sauce simmer for 2-3 minutes.
Add the Parmesan – Stir in the grated Parmesan cheese and red pepper flakes (if using), allowing the sauce to thicken slightly.
Combine Everything – Return the cooked chicken to the skillet, then add the drained fettuccine. Toss everything together until evenly coated in the creamy sauce.
Garnish & Serve – Sprinkle with fresh basil and extra Parmesan cheese before serving. Enjoy warm!
