Ingredients

Scale
  • 34 pounds chuck roast
  • 34 large yellow or sweet onions, thinly sliced
  • 34 cups beef broth (or beef consommé)
  • 12 packets dry French onion soup mix
  • 12 tablespoons Worcestershire sauce
  • 2 tablespoons balsamic vinegar or red wine vinegar
  • kosher salt
  • freshly ground black pepper
  • bay leaf (optional)
  • fresh thyme sprigs (optional)
  • 12 tablespoons olive oil or vegetable oil (for searing)
  • 2 tablespoons cornstarch (optional, for thickening)
  • 3 tablespoons cold water (optional, for thickening)

Instructions

  1. Prep Your Ingredients: Take the chuck roast out of the refrigerator about 30 minutes before cooking. Pat it dry with paper towels and season generously with kosher salt and freshly ground black pepper. Thinly slice all your onions.
  2. Sear the Beef: Heat 1-2 tablespoons of olive oil or vegetable oil in a large skillet over medium-high heat. Sear the seasoned chuck roast for 3-5 minutes per side until golden-brown. Transfer the roast to the slow cooker.
  3. Deglaze the Pan: If there are browned bits in the pan, add a splash of beef broth or water and scrape them up. Pour this liquid into the slow cooker with the roast.
  4. Layer and Liquid Up: Spread half of the sliced onions on the bottom of the slow cooker. Place the seared chuck roast on top, then scatter the remaining onions over and around the roast. Whisk together the beef broth, Worcestershire sauce, and vinegar, then pour over the roast and onions. Sprinkle the dry French onion soup mix over everything and add bay leaf or thyme if using.
  5. Slow Cook to Perfection: Cover the slow cooker and cook on low for 8-10 hours or on high for 4-6 hours until the beef is fork-tender.
  6. Shred and Serve: Remove the chuck roast from the slow cooker and shred it into bite-sized pieces using two forks. If desired, thicken the gravy with a cornstarch slurry. Return the shredded beef to the gravy and stir to combine. Adjust seasonings if necessary before serving.

Nutrition

Keywords: Searing the roast adds depth of flavor. Use plenty of onions for a rich gravy. Cooking on low for longer yields the most tender results. A splash of vinegar brightens the flavors. A cornstarch slurry can thicken the gravy if desired.
