  • 1 (10.5-ounce) can cream of mushroom soup

Recommended Equipment

Instructions

  • Place the pot roast in the slow cooker.
    3 pounds beef chuck roast
  • Arrange the potatoes and carrots around the roast.
    2 to 3 pounds small red potatoes | 4 large carrots
  • Combine the soup, onion soup mix, and beef broth; pour the mixture over the roast and potatoes.
    1 (10.5-ounce) can cream of mushroom soup | 1 (1-ounce) packet onion soup mix | 1 cup beef broth
  • Cover and cook on HIGH for 1 hour. Turn to LOW and cook for 6 to 8 hours longer, or until the roast is very tender.
  • Skim the fat from the liquids or pour them into a fat separator. Return the defatted liquids to a saucepan and bring to a boil over medium-high heat. Continue boiling for 2 to 4 minutes, or until reduced slightly and the flavors are concentrated.
  • Optional: To thicken the liquids, combine 1 tablespoon of cornstarch with 1 tablespoon of cold water. Mix until smooth; stir into the boiling broth and continue cooking until thickened.
    1 tbsp cornstarch | 1 tbsp cold water

Notes

*You may replace the onion soup mix and beef broth with a 10.5-ounce can of condensed French onion soup.
