Gather the ingredients.

Spread 1/2 of the onion slices in the bottom of the slow cooker. Arrange 5 pork chops on top. Repeat layering with remaining onion and pork chops.

Pour both condensed soups and water over pork chops and onion. Sprinkle dressing and soup mixes over top, then season with salt and pepper.

Cover and cook on Low for 4 1/2 to 5 hours or High for 2 1/2 to 3 hours. An instant-read thermometer inserted into the center should read at least 145 degrees F (63 degrees C).
