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