01 - Preheat the oven to 325°F. Pat beef dry and season generously with salt and pepper.
02 - Heat olive oil in a large Dutch oven over medium-high heat. Sear beef in batches until browned on all sides, then remove and set aside.
03 - Reduce heat to medium and add butter, onion, carrots, and celery to the pot. Sauté for 5 minutes until slightly softened. Add garlic and cook for 1 minute.
04 - Stir in tomato paste and cook for an additional minute.
05 - Pour in red wine, scraping up any browned bits from the pot’s base. Let simmer for 2 minutes.
06 - Return beef to the pot. Add beef broth, thyme, rosemary, and bay leaves. Bring mixture to a simmer.
07 - Cover pot with a tight-fitting lid and transfer to the oven. Braise for 2 to 2.5 hours, or until beef is fork-tender.
08 - Remove herbs and bay leaves. Adjust seasoning with salt and pepper as needed.
09 - Serve hot alongside mashed potatoes, polenta, or crusty bread.
