After putting your beef roast into your crockpot, cover with the two can's of cream of mushroom soup and sprinkle with the packet of Lipton Onion Soup mix. If using a frozen roast, you are ready to cover and cook (additional water will come from frozen roast). If using a thawed roast, then add a 1/4-1/3 can of water into the pot. Cover and set crockpot to high for six hours or medium for eight hours. The mixture will create it's own incredible gravy, that will knock your socks off! Sooo good! When you are ready to serve, remove roast from pot and set aside on platter to rest for 5 minutes or so. Stir the gravy until smooth. Serve with mashed potatoes and a veggie for a scrumptious, pure comfort food dinner that your family is going to go nuts over! I promise!
