In a large skillet, heat a tablespoon of olive oil over medium heat. Add the chicken breasts and season them with salt and pepper. Sauté for about 6-7 minutes on each side, or until they are golden brown and cooked through.
Once the chicken is cooked, remove it from the skillet and set it aside. In the same skillet, add the minced garlic and sun-dried tomatoes. Sauté for about 1-2 minutes, allowing the garlic to become fragrant.
Next, pour in the heavy cream and stir in the grated parmesan cheese. Allow the mixture to simmer for about 3-5 minutes, stirring occasionally.
While the sauce is simmering, bring a large pot of salted water to a boil. Add the fettuccine pasta and cook according to package instructions until al dente.
Drain the pasta and add it directly to the skillet with the creamy sauce. Slice the cooked chicken and place it on top. Gently toss everything together, ensuring the pasta is well-coated in the sauce.
Finally, fold in the fresh spinach. The residual heat will wilt the spinach perfectly.
Plate your dish and garnish with extra parmesan cheese and fresh herbs if desired. Serve immediately for the best experience.
