Crock Pot Beef Roast Recipe: Crock Pot Beef Roast Summary: I’m not sure who taught me how to make this roast. I think it was my sister, Nancy, but I learned a thing or two about cooking beef from my father-in-law, too. At any rate, this is how I love a roast! My kids went through a “I hate mushrooms” phase. (They may actually still be in that phase.) When the roast was finished, I removed it and used an immersion blender to get rid of any evidence of mushrooms. Ingredients 4-6 pound beef roast (rump or round – a “tougher” cut works best for this method) ¼ cup vegetable oil 1 cup chopped onion 1 envelope onion soup mix, dry 1 – 2 (10.75 ounce) cans cream of mushroom soup Instructions Cook onion in oil for 1-2 minutes. Brown roast in skillet with onions, 4-5 minutes on each side. Combine dry soup mix with mushroom soup in crock pot. Place roast and onions in crock pot with soup mixture. Spoon soup over roast and cook on low 4-6 hours. Serve with mashed potatoes... I just got chills. Tougher cuts of meat are best when cooked low and slow. A more tender cut of beef will turn to mush if cooked this long. Microformatting by hRecipe. Posted on January 23, 2011 by Karma in the Kitchen and filed under Entrées and tagged Entrées - Beef.
