Preheat your oven to 400F and move the rack to the top third of the oven.
Place the chicken breasts side-by-side in a 9x13 baking dish. Sprinkle them with the garlic powder, Italian seasoning, and some salt & pepper.
In a medium bowl, whisk the cream, chicken broth, white wine, tomato paste, cornstarch, oregano, garlic, and crushed red pepper flakes together until smooth, then stir in the sun-dried tomatoes.
Pour the sauce around the chicken.
Bake, uncovered, for 30-35 minutes or until the chicken is cooked through (165F). Keep in mind ovens vary as does the thickness of chicken breasts, so test early!
Take it out of the oven. Give the sauce a stir and spoon it over the chicken. Sprinkle the parmesan and basil on top. Let the chicken rest for 5 minutes prior to serving or cutting. Season with extra salt & pepper if needed.
