Preheat oven to 375°F.
Place a Dutch oven over medium-high heat. Add EVOO and butter. Season the beef with salt and pepper and add to pot. Brown on all sides, about 6-8 minutes. Add onions, carrots and turnips, and cook for 4-5 minutes. Add flour, stir to combine and coat.
Add the apple cider and the beef consommé, and stir to combine. Bring to a boil, cover and place in the oven for 1-1 1/2 hours.
Once the beef is about 3/4 of the way cooked (about 40-45 minutes after putting it in the oven), place potatoes in a large sauce pot, cover with water by at least 1-2 inches and place over high heat. Once the water comes to a boil, add some salt and cook potatoes until tender, about 15 minutes.
