Equipment

  • 6-quart slow cooker
  • Large skillet
  • Medium saucepan
  • Whisk
  • Sharp carving knife

Ingredients

  • 1 boneless beef sirloin tip roast 2 ½ to 3 pounds
  • 1 tablespoon olive oil
  • 1 teaspoon dried thyme
  • 1 teaspoon dried rosemary
  • Salt and black pepper to taste
  • 1 medium yellow onion sliced thin
  • 3 cloves garlic peeled and smashed
  • 1 cup low-sodium beef broth
  • 2 tablespoons Worcestershire sauce
  • 2 tablespoons cornstarch
  • 3 tablespoons cold water

Instructions

  • Using paper towels, pat the beef roast completely dry. Season with salt, pepper, thyme, and rosemary all over.
  • In a large skillet, heat the olive oil over medium-high heat. Add the beef roast and sear for 2 to 3 minutes on each side, or until well-browned on all sides.
  • Place the sliced onion and crushed garlic cloves in the bottom of a 6-quart slow cooker.
  • Place the seared beef roast on top of the onions and garlic.
  • Pour in the beef broth and Worcestershire sauce.
  • Cover and cook on LOW for 6 to 8 hours, or until the beef is fork-tender.
  • Remove the beef roast from the slow cooker and place on a cutting board to rest for 10 to 15 minutes.
  • Strain the cooking liquid into a medium saucepan and bring to a simmer.
  • Whisk together the cornstarch and cold water in a small bowl until smooth. Whisk the cornstarch mixture into the simmering liquid and cook for 1 to 2 minutes, or until the sauce has thickened.
  • Slice the beef roast thinly against the grain and serve with the gravy drizzled over the top.
