- Heat olive oil in a large Dutch oven over medium-high heat. 
- Season the beef pieces with salt and pepper, then add them to the pot in batches, browning on all sides. Remove the beef and set aside. 
- In the same pot, add the diced onion, carrots, and celery. Sauté for about 5 minutes until the vegetables are softened. 
- Add the minced garlic and cook for an additional minute. 
- Stir in the tomato paste, then pour in the red wine, scraping up any browned bits from the bottom of the pot. Bring to a simmer and let it cook for about 5 minutes. 
- Return the browned beef to the pot along with the beef broth, thyme, rosemary, and bay leaves. 
- Bring the mixture to a boil, then reduce the heat to low. Cover and let it simmer for 2 to 3 hours, or until the beef is tender and easily shreds with a fork. 
- Once cooked, remove the bay leaves and adjust seasoning with salt and pepper as needed. 
- Serve hot over mashed potatoes or with crusty bread.
