This recipe is from the 125th Anniversary Cookbook of St. Paul’s Lutheran Church in Atlantic. It was passed along by Colleen Lange. I have used it numerous times. It is easy and yummy. I use a boneless rump roast but any less expensive (than prime rib) roast will work.

1 (2 to 5 lb.) beef roast
1 pkg. au jus mix
1 pkg. Italian dressing mix
1 can beef broth
1/2 can water
Put beef roast into crock-pot. Combine other ingredients and pour over meat. Cook on low for 8 to 10 hours. Slice and pour juice over pieces to serve.
