This makes a nice dinner to come home to, you can use from a 3-pound to a 5-pound roast for this recipe, don't add any extra salt to this recipe, the seasonings have plenty of added salt to them, and 1/3 cup dry red wine can be added if desired. This is a very good recipe for crock pot roast! Servings are only estimated depending on the size of roast you are using. I prefer to use blade roast but you can use any pot roast you desired even a pork butt roast would would with this!
