Scatter the prepared potatoes, carrots, and onions in the bottom of a slow cooker.
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.
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.
Place cover on slow cooker and cook on low for about 6-8 hours, or until beef is fall-apart tender.
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.
