Preheat oven to 275°F.
Heat oil in a large Dutch oven over medium-high heat. Sear the roast on all sides until browned, about 4 minutes per side.
Remove roast and set aside. Add onion and garlic to the pot and sauté for 2-3 minutes.
Stir in beef broth, balsamic vinegar, tomato paste, Worcestershire sauce, salt, pepper, thyme, and paprika.
Return roast to the pot. Add potatoes and carrots around the meat.
Cover and cook in the oven for 3.5 to 4 hours, until meat is tender.
Remove roast and vegetables. Mix corn starch and water, then stir into the pot juices. Simmer on the stove for 5 minutes until thickened.
Slice roast and serve with veggies and gravy.
