An easy, comforting meal, with fall-apart tender beef, carrots and potatoes, all in a tangy tomato gravy.



  • 6 medium yellow-fleshed potatoes peeled and halved
  • 6-8 carrots peeled and halved if thick or left whole if thinner
  • 1 medium onion peeled and thinly sliced
  • 1 Tbsp olive oil
  • Salt and freshly ground pepper
  • 3 lb boneless beef roast inside or outside round, blade or cross-rib works well
  • 2 cups tomato sauce or passata
  • 1/4 cup brown sugar packed
  • 2 Tbsp Worcestershire sauce
  • 2 Tbsp cider vinegar
  • 2-3 fresh thyme sprigs or 1 tsp dried thyme leaves
  • 1 tsp salt
  • Freshly ground pepper

To thicken:

  • 1 Tbsp cornstarch
  • 1 Tbsp water

To serve:

  • Fresh parsley chopped


  1. Scatter the prepared potatoes, carrots, and onions in the bottom of a slow cooker.
  2. On the stove top, heat oil in a large skillet over medium-high heat. Sear beef roast on both sides until well browned, about 3 minutes per side. Place beef on top of vegetables in slow cooker.
  3. In a medium bowl, stir together the tomato sauce, brown sugar, Worcestershire sauce, cider vinegar, salt and pepper. Pour over the roast. Scatter the fresh thyme sprigs over-top.
  4. Place cover on slow cooker and cook on low for about 6-8 hours, or until beef is fall-apart tender.

  5. Remove roast to a cutting board and cut in to slices. Meanwhile, combine cornstarch with water and stir in to gravy with vegetables and let cook for a few minutes until gravy thickens a bit. Taste gravy and season with additional salt and pepper, as needed. Return meat to slow cooker. Gently stir to coat with gravy. Allow to cook a few minutes to re-warm the meat, then remove all to a large platter or bowl to serve. Garnish with some chopped fresh parsley.
