01 - Pat the beef cubes dry with paper towels and season generously with salt and pepper.
02 - In a large Dutch oven or heavy-bottomed pot, heat 2 tablespoons olive oil over medium-high heat. Brown the beef in batches, adding more oil as needed, about 3–4 minutes per batch. Set browned beef aside.
03 - Reduce heat to medium. Add onion and celery to the pot and cook for 4 minutes until softened. Stir in garlic, cook for 1 minute.
04 - Sprinkle flour over the vegetables and stir for 1–2 minutes.
05 - Add tomato paste, stirring to coat the vegetables. Pour in red wine, scraping up any browned bits from the bottom of the pot.
06 - Return the beef to the pot. Add beef stock, Worcestershire sauce, bay leaves, thyme, and rosemary. Stir to combine.
07 - Bring to a simmer, cover, and cook on low heat for 1.5 hours, stirring occasionally.
08 - Add carrots, parsnips, potatoes, and rutabaga. Stir well, cover, and cook for another 45–60 minutes, until vegetables and beef are tender.
09 - Remove bay leaves, adjust seasoning with salt and pepper. Garnish with fresh parsley before serving.
