01 - Heat olive oil in a large heavy-bottomed pot over medium-high heat. Brown the beef in batches until well-seared on all sides. Remove and set aside.
02 - Reduce heat to medium. In the same pot, add onions, carrots, and celery. Sauté for 5 minutes, scraping up any browned bits from the bottom.
03 - Add the garlic and tomato paste. Cook for 2 minutes until fragrant, stirring to combine with the vegetables.
04 - Deglaze the pot with red wine, scraping the bottom to release all fond. Allow the wine to reduce by half, about 5 minutes.
05 - Return the seared beef to the pot. Add potatoes, beef stock, bay leaves, rosemary, thyme, salt, and pepper. Stir to combine.
06 - Bring to a gentle simmer. Cover and cook on low heat for 2 hours, stirring occasionally, until the beef is fork-tender and the sauce has thickened.
07 - Remove and discard the bay leaves and rosemary sprig. Adjust seasoning with salt and pepper as needed before serving.
