Start by boiling water with a pinch of salt. Add the penne and cook until al dente, about 9-11 minutes. Drain and toss with a little olive oil to prevent sticking.
Heat olive oil in a large skillet over medium-high heat. Add the cubed chicken, season with salt and pepper, and cook until golden brown and cooked through, about 5-6 minutes.
Reduce heat to medium, add garlic and sun-dried tomatoes to the pan. Sauté for 1-2 minutes until the garlic is fragrant but not burnt.
Pour in the chicken broth and heavy cream, stirring constantly. Let it simmer for 3-4 minutes until it slightly thickens. Add Parmesan cheese and Italian seasoning, mixing until smooth.
Add the cooked penne to the skillet, tossing gently to coat evenly. Let it cook together for another 2-3 minutes so the pasta absorbs the flavors.
Top with fresh basil and an extra sprinkle of Parmesan. Serve hot, straight from the pan for the best presentation.
