Remove all the husks and corn silk from the ears of corn. Place the in a slow cooker with the broth or water and cover and cook on low for 3 hours. (Make sure the lid fits on all the way so the corn cooks properly. If the corn doesn’t fit, they can be broken in half to accommodate more.)
Once cooked, drain the water. Melt the butter and add the salt and pepper, parsley in the microwave and whisk together.
Brush the mixture over the ears to coat each one and enjoy warm.
