Preheat your oven to 350 degrees.

Salt the pork chops and arrange them in a large baking dish.

Place a slice of onion and lemon on each chop.

Combine the brown sugar and ketchup and spoon a couple of tablespoons over each chop.

Cover the dish and bake for 1 hour.

Remove the cover and continue baking for an additional 30 minutes, basting occasionally.
