Pat the beef round dry and season evenly with sea salt and black pepper.
Heat the olive oil in a heavy-bottomed pot or Dutch oven over medium-high heat.
Sear the beef on all sides until a deep golden-brown crust forms, then remove and set aside.
Add the diced onion, carrot, and celery to the same pot, sautéing until the vegetables begin to soften.
Stir in the minced garlic and tomato paste, cooking for 1 minute until fragrant.
Pour in the red wine to deglaze the pot, scraping up any browned bits from the bottom.
Add the beef back to the pot along with the bone broth, thyme, and rosemary.
Cover and reduce heat to low, simmering for 2 to 3 hours until the beef is fork-tender and the sauce has thickened.
