Spray a 6-quart crock pot with nonstick cooking spray.
Add beef broth, both cans of soup, and the onion mushroom soup mix to the crock pot. Whisk until combined.
Pat the pork chops dry. Sprinkle salt, pepper, garlic powder, and paprika evenly over both sides.
Sear the pork chops: Heat olive oil in a large skillet over medium-high heat. Sear pork chops for 2 minutes per side until golden brown. Transfer them to the slow cooker.
In the same skillet, add sliced mushrooms. Sauté for 3–4 minutes, just until they get some color. Pour them over the pork chops in the crock pot.
Cover and cook on low for 5 hours or high for 2 ½ hours, until the pork is fork-tender.
Spoon the creamy mushroom gravy over the pork chops and serve with mashed potatoes, pasta, or rice.
