Step 1

Spread about half the onion slices into the bottom of the slow cooker. Arrange 5 pork chops atop the onion layer. Repeat layering with remaining onion and pork chops.

Step 2

Pour cream of onion soup, cream of mushroom soup, and water over the pork chops and onion. Sprinkle ranch dressing mix and onion soup mix over the pork chops; season with salt and pepper.

Step 3

Cook on High until the pork chops are tender to your liking, 2 1/2 to 3 hours. Alternately, you can cook on Low for 4 1/2 to 5 hours. An instant-read thermometer inserted into the center should read at least 145 degrees F (63 degrees C).
