Begin by seasoning the chicken breasts lightly with salt and pepper. Heat the skillet with olive oil over medium-high heat. Once hot, sear the chicken for 5–6 minutes on each side until golden brown. Set the chicken aside.
Reduce heat to medium and sauté the minced garlic in the same skillet until fragrant, about 1 minute.
Pour in the chicken broth and heavy cream, stirring well. Add the sundried tomatoes and let the sauce simmer for about 5 minutes.
Add in the grated Parmesan cheese, mixing until melted. Return the chicken to the skillet, coat with sauce.
Reduce the heat to low, allowing the dish to simmer for another 10 minutes. Finish with fresh basil leaves before serving.
Notes
Store any leftovers in an airtight container in the fridge for up to three days. Gently reheat on the stove before serving.
