Ingredients

Scale
  • 1 pot roast, lean chuck, about 3 pounds
  • 2 to 3 pounds small red potatoes, scrubbed and peeled, halved
  • 4 large carrots, halved lengthwise and sliced into 3-inch lengths
  • 1 can (10 3/4 ounces) condensed cream of mushroom soup
  • 1 can (10 3/4 ounces) condensed French onion soup or 1 envelope onion soup mix and 1 cup beef broth
  • 1 tablespoon cornstarch or flour and 2 tablespoons water, optional

Instructions

  1. Place the pot roast in the slow cooker.
  2. Arrange the potatoes and carrots around the roast.
  3. Combine the soups and then pour the mixture over the roast and potatoes.
  4. Cover and cook on HIGH for 1 hour.
  5. Turn to LOW and cook for 6 to 8 hours longer, or until the roast is very tender.
  6. Defat the liquids and pour them into a saucepan; bring to a boil. Continue boiling for about 3 to 5 minutes, or until reduced slightly and the flavors are concentrated.
  7. If a thicker sauce is desired, combine 1 tablespoon of flour or cornstarch with 1 or 2 tablespoons of water. Mix until smooth; stir into the boiling broth and continue cooking until thickened.
