- Prep the oven to 350F, and place the arm roast on a lined baking pan. Season generously on all sides with pepper and salt, then set aside.
- Heat the oil in a Dutch oven over a medium-high stove, and sear the arm roast until it develops a deep crust on all sides.
- Add the beef stock and tomatoes to the Dutch oven, then spread the herbs and chopped aromatics around the meat. Adjust the seasoning as desired and cover the Dutch oven.
- Place the Dutch oven in the oven and braise for three hours, basting the meat every 30 minutes with the pot liquid. Cook until the meat hits 145F or reaches a fork-tender texture.
- Serve the pot roast as desired and with the cooked vegetables.
