Preheat a skillet over medium-high heat and add in the butter.
Coat the chicken generously with the seasoned flour and shake off any excess.
Sear the chicken in the butter for 2 mins per side until nice and golden.
Remove the chicken on a plate and add in the remaining butter to the same skillet without washing it.
Add in the garlic, lemon slices, fresh thyme, capers, and artichokes and sauté for a minute.
Add in the lemon juice and stock, then place the chicken back in the mixture and let it cook over medium-high heat for about 3-5 mins.
Add in the Greek yogurt and take the skillet off the heat. Mix the sauce to blend, season and serve.
