1 (3-4 pounds) chuck roast
1 packet ranch dressing mix
1 packet au jus gravy mix
1/4 cup butter
4-5 pepperoncini peppers (or small jar sliced)
Place crock pot liner in slow cooker. Place roast in the slow cooker and sprinkle the top with the ranch dressing mix and the au jus mix.
Place peppers on top of the mixes and add the butter.
Cook over low heat for 8 hours. Serve with noodles, rice or mashed potatoes. May also use forks to pull apart to use for sandwiches.
Do not add any water or broth to this. It will make enough liquid as it cooks.
