Season the pork chops evenly on both sides with the salt, black pepper, garlic powder, and onion powder.
(Optional but recommended) Heat the olive oil in a skillet over medium-high heat. Sear the pork chops for 2 minutes per side just until deeply browned. This locks in extra savory flavor, but you can skip this step if you are in a rush!
Transfer the seasoned (or seared) pork chops directly into the bottom of your slow cooker.
In a medium bowl, whisk together the cream of mushroom soup, the dry ranch dressing mix, and the chicken broth until smooth and combined.
Pour the soup mixture evenly over the pork chops in the slow cooker, ensuring they are well covered.
Place the lid on the slow cooker. Cook on LOW for 6-7 hours, or on HIGH for 3-4 hours. The chops are done when they are incredibly tender and easily pull apart with a fork.
Serve the pork chops hot, generously spooning the rich, slow-cooked gravy right over the meat and your favorite side dishes.
