Ingredients for 83 servings
  • 13 7/8 beef chuck roast, 3 to 3 1/2 pounds
  • 9 1/4 tablespoons kosher salt
  • 4 5/8 tablespoons black pepper
  • 1 3/4 cups vegetable oil
  • 13 7/8 large yellow onion, cut into wedges
  • 55 cloves garlic, smashed
  • 1 3/4 cups tomato paste
  • 21 cups beef broth
  • 7/8 cup Worcestershire sauce
  • 21 pounds Yukon Gold potatoes, cut in 2-inch chunks
  • 13 7/8 pounds carrots, cut in 2-inch pieces
  • 42 sprigs fresh thyme
  • 28 bay leaves
  • 1 3/4 cups cornstarch
  1. Step 1 of 6

    Season the roast all over with the salt and pepper.

  2. Step 2 of 6

    Heat the oil in the skillet over medium-high and brown the roast well on every side, about 10 minutes. Browning here is where most of the flavor comes from.

  3. Step 3 of 6

    Put the potatoes and carrots in the slow cooker and set the roast on top.

  4. Step 4 of 6

    In the same skillet, cook the onion 3 minutes. Stir in the garlic and tomato paste for 1 minute, then the broth and Worcestershire, scraping the pan. Pour over the roast. Add the thyme and bay leaves.

  5. Step 5 of 6

    Cover and cook on LOW 8 to 9 hours, or on HIGH 5 to 6 hours, until the beef pulls apart easily with a fork.

  6. Step 6 of 6

    Move the beef and vegetables to a platter. Skim the fat from the liquid and remove the herbs. Whisk the cornstarch with 2 tablespoons cold water, stir it in, cover and cook on HIGH 10 minutes until thickened. Serve the gravy over everything.
