01 - Pat the beef cubes dry with paper towels and season generously with salt and pepper.
02 - Heat 2 tablespoons olive oil in a large Dutch oven over medium-high heat. Brown beef in batches for 3–4 minutes per side until seared. Transfer to a plate.
03 - Add remaining olive oil to the pot. Sauté onion, carrots, parsnips, celery, and rutabaga for 5 minutes. Add garlic and cook 1 minute until fragrant.
04 - Stir in tomato paste and cook for 1 minute to deepen flavor.
05 - Return beef to pot. Pour in red wine, scraping up browned bits from bottom. Simmer for 2–3 minutes.
06 - Pour in beef broth. Add bay leaves, thyme, and rosemary. Bring to a gentle simmer.
07 - Reduce heat to low, cover, and cook for 1.5 hours. Stir occasionally to prevent sticking.
08 - Add diced potatoes and continue simmering covered for 30 minutes until vegetables and beef are fork-tender.
09 - For thicker consistency, whisk cornstarch or flour with 2 tablespoons cold water. Stir into stew and simmer uncovered 5–10 minutes until desired thickness.
10 - Discard bay leaves. Stir in fresh parsley. Adjust seasoning if needed. Serve hot, garnished with extra parsley.
