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.
Place the roast in a roasting pan with the onion and carrots.
Pour the beef broth into the pan.
Insert a meat thermometer into the thickest part of the roast.
Roast in the oven until the thermometer reads 135°F (57°C) for medium-rare.
Remove the roast from the oven and cover with foil.
Let it rest for 15-20 minutes before slicing.
