Pat the chicken breasts dry and season with salt, pepper, and Italian seasoning.
Heat olive oil in a large skillet over medium-high heat.
Sear the chicken for 4–5 minutes per side until golden brown. Remove from the skillet and set aside.
In the same skillet, add a little more olive oil if needed.
Sauté the garlic and sun-dried tomatoes for 1–2 minutes until fragrant.
Pour in the chicken broth, scraping up any browned bits from the skillet.
Stir in the heavy cream and let it simmer for 2–3 minutes.
Return the chicken breasts to the skillet and spoon the sauce over them.
Cover and let simmer for 8–10 minutes, or until the chicken is cooked through (internal temperature of 165°F).
Garnish with fresh basil or Parmesan cheese and serve hot with your favorite sides.
