Start by drying the chicken breasts with a towel and seasoning them with salt, pepper, and herbes de Provence.
In a large pot or skillet, heat the olive oil over medium-high heat. Place the seasoned chicken breasts in the pot and sear them on both sides until they develop a golden-brown crust.
Once the chicken is nicely browned, add the chicken broth, sun-dried tomatoes, fresh basil, and Greek yogurt to the pot. Stir everything together to combine the flavors.
Reduce the heat to medium-low and let the chicken simmer in the sauce for about 15-20 minutes, allowing the flavors to meld together and the sauce to thicken slightly. Make sure to stir occasionally to prevent sticking.
Once the chicken is fully cooked and the sauce has reached the desired consistency, remove the pot from the heat.
Serve the Marry Me Chicken hot, spooning the flavorful sauce over the chicken breasts.
