Heat a large Dutch oven or heavy pot over medium heat and add the oil. Season the meat with the spice mix and some salt and pepper. When the oil is hot, add the meat and cook, without stirring, until brown, 3 to 5 minutes. Stir the meat, then add the root vegetables and cook, stirring occasionally, for 2 to 3 minutes.
Add the flour and tomato paste if using, mix thoroughly and cook an additional minute. Add the liquid and bring to a simmer. Add the potatoes and rosemary. Simmer until the meat is tender, about 1 1/2 hours.
