On a plate, combine salt, pepper and thyme. Coat meat in all sides with spices. Heat oil in a large saucepan and brown meat on both sides, turning once, about 7 minutes total. Meanwhile, place carrots, potatoes, onions and garlic in a 5 or 6-quart slow cooker. Top with browned roast. Pour 2 tablespoons water into the pan you browned the roast in, scrape up any browned bits and add that rich liquid to the slow cooker along with the beef broth and tomato paste. Cover and cook until beef and vegetables are very tender, 8 to 10 hours on the low-heat setting or 4 to 5 hours on the high-heat setting.
GF/DF/Paleo – omit potatoes and increase amount of carrots.
