Ingredients

  • 3-4 pounds rump roast, trimmed of excess fat
  • 2 tablespoons olive oil
  • 1 large onion, sliced
  • 4 cloves garlic, minced
  • 3 large carrots, peeled and cut into chunks
  • 3 celery stalks, chopped
  • 1 cup beef broth
  • 1/2 cup red wine (optional but recommended)
  • 2 tablespoons Worcestershire sauce
  • 1 teaspoon dried thyme
  • 1 teaspoon dried rosemary
  • 1 teaspoon salt (adjust to taste)
  • 1/2 teaspoon black pepper
  • 2 bay leaves
  • 2 tablespoons cornstarch (optional, for gravy)
  • 2 tablespoons water (optional, for gravy)

Equipment

  • Slow cooker (6-quart or larger recommended)
  • Large skillet or frying pan for searing the meat
  • Sharp knife and cutting board
  • Measuring spoons
  • Mixing bowl (optional, for gravy)
  • Tongs for handling the roast

Instructions

  1. Prepare the roast: Remove the rump roast from the refrigerator about 30 minutes before cooking to bring it to room temperature. Pat it dry with paper towels to ensure a good sear.
  2. Season the meat: Generously season the roast all over with salt, black pepper, dried thyme, and rosemary. This will enhance the flavor as it cooks.
  3. Sear the roast: Heat the olive oil in a large skillet over medium-high heat. Once hot, sear the rump roast on all sides until browned, about 3-4 minutes per side. This step locks in the juices and adds a rich flavor.
  4. Prepare vegetables: While the roast is searing, place the sliced onions, carrots, and celery at the bottom of the slow cooker. This creates a flavorful bed for the roast to rest on.
  5. Transfer and add liquids: Place the seared rump roast on top of the vegetables in the slow cooker. Add minced garlic, beef broth, red wine (if using), and Worcestershire sauce around the roast. Add the bay leaves as well.
  6. Cook low and slow: Cover the slow cooker and cook on low for 8-10 hours or on high for 4-5 hours. The rump roast should be fork-tender and easy to shred when done.
  7. Make the gravy (optional): Once the roast is cooked, carefully remove the meat and vegetables from the slow cooker and set aside. Pour the cooking liquid into a saucepan. In a small bowl, mix cornstarch with water to make a slurry, then whisk it into the cooking liquid. Heat on medium, stirring constantly until the gravy thickens.
  8. Serve: Slice or shred the rump roast and serve with the cooked vegetables and warm gravy on top.

Tips & Variations

“For the best flavor, sear your roast before slow cooking. It’s a game-changer!”

  • Vegetable substitutions: Swap the carrots and celery for potatoes, parsnips, or mushrooms depending on what you like or have on hand.
  • Herb variations: Try fresh herbs like rosemary or thyme if available; just add them towards the end of cooking to maintain their bright flavor.
  • Make it spicy: Add a pinch of red pepper flakes or a dash of smoked paprika for a smoky kick.
  • Extra tender: Cook the roast on low for a longer time (up to 12 hours) for ultra-tender results, perfect for shredding.
  • Slow cooker liner: Use a slow cooker liner to make cleanup easier.
