Pat the chicken breasts dry with paper towel, then season with salt and pepper. Heat the olive oil in a skillet over medium heat, then sear both sides of the chicken breasts.
Separate the cloves of garlic, but don't peel them. Smash each clove with the flat side of a knife or a heavy bottle so they're broken a little, but not fully out of the skin.
Add the smashed garlic cloves to the skillet and sauté for about 5 minutes, or until the skin is golden brown.
Take the sautéed garlic out of its skin, then purée it with the chicken stock using an immersion blender. (You can also mash the garlic with a fork and mix it into the stock.)
Add the chicken back to the pan, then cover it with the garlic and stock mixture, white wine, and bay leaves. Cover and simmer for 10 minutes, then uncover and simmer for another 5 minutes.
Remove the chicken from the heat and let it stand for 5 minutes, then serve in bowls with the sauce. Enjoy while it's hot!
