Pat pork chops dry and season both sides with salt and black pepper.
Heat olive oil in a skillet over medium-high heat and sear pork chops for 2–3 minutes per side until lightly browned (optional but recommended).
Add sliced onion and garlic to the bottom of the slow cooker.
Place pork chops on top of the onions.
Pour in broth and Worcestershire sauce, then sprinkle herbs over the pork.
Cover and cook on LOW for 6–7 hours or HIGH for 3–4 hours, until pork is tender.
Optional: Remove pork chops and thicken the sauce with a cornstarch slurry or stir in cream on LOW heat.
Return pork chops to the slow cooker and serve warm.
