Pat the chicken breasts dry with a paper towel. Season both sides with salt, pepper, and garlic powder. Heat olive oil in a large skillet over medium-high heat and sear the chicken for about 6-7 minutes on each side. Set aside.
In the same skillet, add sun-dried tomatoes. Cook for 2-3 minutes, then add chicken broth, scraping the bottom of the pan to deglaze.
Stir in heavy cream and allow it to simmer for 5 minutes. Add Parmesan cheese and stir until melted and creamy.
Boil a large pot of salted water, add pasta, and cook until al dente. Reserve a cup of pasta water, drain the rest, and set the pasta aside.
Slice the chicken and return to the skillet. Combine with pasta, tossing everything to coat in sauce. Adjust with pasta water if needed. Serve warm.
Notes
Store leftovers in an airtight container for up to three days. Reheat gently with additional cream or broth to maintain sauce consistency.
