Combine rosemary, ground pepper, and salt in a small bowl; rub rosemary mixture on pork chops.

Melt butter in a large skillet over medium-high heat; stir garlic into melted butter, then place pork chops in the skillet. Cook until golden brown, 3 to 5 minutes per side.

Reduce heat to low and pour in beef broth. Simmer until pork chops are fully cooked, 35 to 45 minutes. A meat thermometer inserted into the center of the thickest chop should read at least 145 degrees F (63 degrees C).
