Season your chicken breasts with the salt, pepper, thyme, oregano, and parsely. I didn't put the exact measurements so that you can season to your own taste! I usually just sprinkle a light coat over each side.
Peel and dice your sweet potatoes. In a bowl, combine the diced sweet potatoes, olive oil, salt, pepper, and rosemary.
In a large pan, I usually use a cast iron, melt the butter and add the olive oil over medium heat. Place the chicken breasts and sweet potatoes in the pan.
Cook the chicken 5 minutes on each side. Every so often, stir the sweet potatoes a little.
Once the chicken and sweet potatoes are done cooking, take them out of the pan and set them aside.
In the same pan over medium heat, add the butter, garlic, chicken broth, and heavy cream and combine. Let it cook for 1-2 minutes.
Add the white wine and let it cook off for about 5 minutes.
Add the salt, pepper, parsley, and thyme and mix.
Add the chicken and sweet potatoes back into the pan, making sure everything is coated in the sauce. Let it cook in the sauce for an additional 1-2 minutes.
