Preheat your oven to 275°F (135°C).
Season the chuck roast with salt and pepper.
Heat a Dutch oven over medium-high heat and sear the roast on all sides until browned.
Remove the roast and set aside. In the same pot, add the onions and garlic, cooking until softened.
Pour in the beef broth and red wine, scraping up any browned bits from the bottom of the pot.
Return the roast to the pot, add the carrots, potatoes, thyme, and rosemary.
Cover and cook in the oven for about 4 hours, or until the meat is tender.
Remove from oven and let rest for a few minutes before serving.
