In a medium or large oven safe skillet, melt the butter over medium-high heat.
Place the chicken thighs in the skillet and fry until golden brown and crispy, turning occasionally to cook both sides.
In a large measuring cup, whisk together the broth, garlic powder, white wine and squeeze the juice from one lemon half into the mixture. Pour into the skillet and mix into the butter mixture.
Cook for another 5 minutes, stirring the sauce occasionally.
Take the other lemon half and cut into slices. Place on top of chicken if desired. If you want the chicken to stay crisp, omit this step.
Sprinkle the rosemary over the chicken.
Place into the oven.
Bake for another 30-35 minutes until the chicken thighs are cooked.
Remove and serve.
Notes
A little sea salt sprinkled on top after serving is perfect!
