My grandmother passed this recipe down to my mom, and it's a gem. The tasty sauce makes the beef and carrots so tender, and it's made with many ingredients you'll already have on hand. You won't want to eat pot roast any other way! —Krista Smith Kliebenstein, Broomfield, Colorado


  • 3 tablespoons all-purpose flour
