Ingredients

For the Roast

  • 3 pounds chuck roast
  • fine sea salt to taste
  • fresh ground black pepper to taste
  • 2 tablespoons avocado oil or other neutral cooking oil
  • 2 tablespoons unsalted butter
  • 3 large yellow onions thinly sliced (about 6-7 cups sliced)
  • 4 cloves garlic minced
  • 3 cups beef broth low sodium or beef stock
  • 2 tablespoons Worcestershire sauce
  • 2 bay leaves
  • 2 teaspoons dried thyme
  • 1 teaspoon dried oregano
  • 2 tablespoons cornstarch
  • 4 tablespoons water for the cornstarch slurry

Optional Cheese Topping

  • 2 cups provolone or Gruyere, shredded

Serve With

  • fresh parsley chopped
  • thick slices of baguette or crusty French bread toasted

Instructions

  • Pat the chuck roast completely dry with paper towels. Season generously on all sides with salt and pepper.
    3 pounds chuck roast, fine sea salt, fresh ground black pepper
  • Heat the avocado oil in your Dutch oven over medium-high heat.
    2 tablespoons avocado oil
  • Place the roast in the hot pot and sear for 4-5 minutes per side, until browned all over. Remove from the pot and set aside on a plate.
  • Reduce the heat to medium-low. Add the butter to the Dutch oven. Once melted, add the onions.
    2 tablespoons unsalted butter, 3 large yellow onions
  • Cook slowly, stirring occasionally, until the onions are caramelized and soft. This takes patience – allow at least 30-45 minutes.
  • Add the minced garlic during the last 30 seconds of cooking the onions, stirring until fragrant.
    4 cloves garlic
  • Increase the heat to medium-high. Pour in the beef broth, Worcestershire sauce, bay leaves, dried thyme and dried oregano. Bring the mixture to a simmer. Taste and add salt and pepper as needed.
    3 cups beef broth, 2 tablespoons Worcestershire sauce, 2 bay leaves, 2 teaspoons dried thyme, 1 teaspoon dried oregano
  • Return the chuck roast and any accumulated juices from the plate to the pot with the simmering liquid. Bring the liquid back to a gentle simmer on the stovetop.
  • Reduce heat to low, cover with a tight-fitting lid, and simmer gently on the stovetop or in a 300°F oven for 3½ to 4 hours, or until the beef is fork-tender. Check occasionally to make sure the liquid is just simmering gently and not boiling; add a bit of water or broth if necessary to maintain liquid level.
  • When the beef is tender, carefully remove the roast from the pot to a large plate or bowl. Remove and discard the bay leaves.
  • In a small bowl, whisk together cornstarch and water to make a slurry. Slowly whisk the slurry into the liquid. Continue to cook and whisk for 1-2 minutes until the sauce thickens.
    2 tablespoons cornstarch, 4 tablespoons water
  • Return the roast to the pot with the thickened sauce. Use two forks to shred the beef directly in the pot, mixing gently to combine the meat evenly with the sauce.

Optional Cheese Topping

  • Sprinkle the roast generously with shredded cheese.
    2 cups provolone
  • Place under a preheated broiler on high for 2-5 minutes, watching closely until the cheese is melted, bubbly, and golden.
  • Garnish with fresh chopped parsley and serve with toasted baguette slices.
    fresh parsley, thick slices of baguette or crusty French bread

Notes

Storage Information
  • Refrigerator: Allow the pot roast to cool to room temperature. Store leftovers in an airtight container for up to 4 days. Reheat gently on the stovetop or in the microwave.
  • Freezer: Freeze cooled pot roast (without the cheese topping) in an airtight, freezer-safe container for up to 3 months. Thaw overnight in the fridge before reheating.
  • Make Ahead: You can prepare the roast a day in advance. The flavors deepen as it rests! Simply reheat and add the optional cheesy topping just before serving.
