In a large pot, bring salted water to a boil and add the penne pasta. Cook according to the package instructions until al dente. Drain and set aside.
In a large skillet over medium heat, heat the olive oil. Add the diced chicken breasts, season with salt, pepper, and Italian seasoning. Cook for about 6-8 minutes or until the chicken is fully cooked and no longer pink. Remove the chicken from the skillet and set aside.
In the same skillet, add minced garlic and sauté for about 1 minute until fragrant. Then, add the sun-dried tomatoes and cook for another 2-3 minutes, allowing the flavors to meld together.
Pour in the heavy cream and bring it to a gentle simmer. Stir in the grated Parmesan cheese, allowing it to melt and create a creamy sauce. Season with additional salt and pepper to taste.
Add the cooked chicken and pasta to the skillet, tossing everything together until well-coated in the creamy sauce. If the sauce is too thick, add a splash of pasta water until the desired consistency is reached.
Remove from heat and let it sit for a minute. Serve the pasta in bowls, garnished with fresh basil leaves and additional Parmesan cheese, if desired.
Notes
Garnish with fresh basil and extra Parmesan cheese if desired.
