Preheat your oven to 325°F (163°C).
Pat the bottom round roast dry with paper towels.
Rub olive oil all over the roast.
Season generously with salt, pepper, garlic, rosemary, and thyme.
Heat a large skillet over medium-high heat.

Place the roast in a roasting pan and surround with onions and carrots.
Pour the beef broth into the pan.
Cover with foil and roast in the oven for 2.5-3 hours.
Remove from oven and let rest for 15 minutes before slicing.
