  • 1 2 to 3-pound or bigger beef eye round or top round roast (or another type of beef roast, such as chuck)
  • 2 T olive oil
  • 1/4 c cornstarch
  • 1 t kosher salt
  • freshly ground black pepper
  • 1 c beef broth/stock
  • 1/4 c balsamic vinegar
  • 2 T tomato paste
  • 1 medium or 1/2 of a large onion quartered
  • 3 garlic cloves smashed and peeled
  • 1 c dry red wine I've used Merlot and Zinfandel
  • 10 oz. cremini baby bella, or white button mushrooms, halved or quartered
  • 1 c baby carrots or whole carrots, peeled and cut into “fingers”
  • 1 large sprig of fresh rosemary
  • 1/2 c frozen peas no need to thaw


  • Heat the olive oil in a pan over medium-high heat.
  • Combine the corn starch, salt, and pepper in a shallow dish.
  • Roll the meat around in the cornstarch mixture until it is coated on all sides. Set aside the remaining cornstarch mixture.
  • Sear the meat in the pan for 2-3 minutes on each side, until it is nice and browned.
  • While the meat is searing, add the reserved cornstarch mixture, broth, balsamic vinegar, and tomato paste to the slow cooker, and stir to dissolve.
  • Remove the meat from the pan, and put it in the slow cooker.
  • Reduce the heat to low and pour the wine into the pan. Scrape up any of the brown bits with a wooden spoon, and pour everything into the crockpot.
  • Arrange the onion, garlic, mushrooms, carrots, and rosemary around the roast.
  • Cook on low for 6-8 hours, or until the meat is cooked through. Add the peas during the last few minutes of cooking.
  • Remove the meat, carrots, and mushrooms from the slow cooker. Ladle out or strain the liquid from the crockpot, and serve on the side as a gravy.
