Season the chuck roast generously with salt and black pepper.
Heat olive oil in a large oven-safe pot over medium-high heat. Add the roast and sear each side until browned, approximately 3-4 minutes per side.
Remove the roast and set aside. In the same pot, add chopped onions and garlic, sautéing until onions are translucent.
Return the roast to the pot. Add beef broth, ensuring it comes about halfway up the sides of the roast.
Cover the pot with a lid and place it in the oven. Cook for 3 hours.
After 3 hours, add the quartered potatoes and chopped carrots around the roast. Cover and return to the oven for another hour, or until the vegetables and roast are tender.
Remove from oven, let the roast rest for a few minutes before slicing. Serve hot with the vegetables.
