Preheat oven to 375ºF.
Place a large pot over medium-high heat with 2 tablespoons EVOO, about 2 turns of the pan. Add the meat to the pot and cook, stirring occasionally, until well-seared on all sides, 7-8 minutes total. Remove the meat from the pot and reserve it on a plate.
Add the bacon to the pot and cook until brown and crispy, 4-5 minutes. Add the onions, carrots, celery, parsnips, turnips, bay leaf, cumin and allspice to the pot, and cook until the veggies begin to get tender, 6-7 minutes.
Add the honey, Worcestershire, Guinness, reserved meat, stock and potatoes to the pot and bring to a bubble. Cover the pot and transfer the stew to the oven. Cook until the meat is tender, about 1 hour.
