Slow Cooker Sweet & Sour Pork Chops

1. Heat a large skillet over high heat. Sear the pork chops until browned, 1 to 2 minutes per side. Transfer the pork chops to a slow cooker. Mix the brown sugar, ketchup, onion, and lemon juice in a bowl; spoon over the pork chops.
2. Cook on Low until the pork chops are very tender, 4 to 6 hours.
