I found this recipe about 12 years ago and it was a oven type and I made it into a crockpot because I was working all the time. This is so good and it makes a great gravy, if you would like more gravy for a larger crowd then I would use 2 cans of soup. You do not need any water or any other spices it is great just the way it is . I serve it with mashed potatoes or butter garlic egg noodles. Your family will love it and they will think you were in the kitchen for a long time but you know it was very easy.
1Sear your roast or whatever type of meat you are using on both sides then put in crock pot. Spread cream of soup over roast. Sprinkle the 6 dashes of Worcestershire sauce on top.
2Then put 1 enevelope of dry onion soup mix over that, put lid on and turn on high till starts to boil. Turn down on low and cook for 6-8 hours. Pending on your slow cooker should be fork tender or falling apart maybe sooner.
