Step 1

Preheat the oven to 375 degrees F (190 degrees C).

Step 2

Combine 1/4 cup brown sugar and butter in a skillet over medium heat. Stir until melted, about 1 minute. Add apple and onion; cook and stir until softened, 5 to 7 minutes. Add pork chop and cook until browned on both sides, 8 to 10 minutes. Remove from heat and transfer pork chop to a plate.

Step 3

Combine remaining brown sugar, water, rosemary, and thyme in a small saucepan over medium-low heat and bring to a boil. Cook just until sauce is syrupy, being careful not to burn the sugar, about 1 minute.

Step 4

Add cooked apple mixture to the sauce, stirring to cover.

Step 5

Wrap a shallow baking dish in aluminum foil for easy cleanup and place browned pork chop in the center. Pour sauce over pork chop making sure apples surround the meat.

Step 6

Bake in the preheated oven until an instant-read thermometer inserted into the center reads 145 degrees F (63 degrees C), 25 to 30 minutes.
