Generously salt and pepper your roast.
Heat a large pot or Dutch oven over medium-high heat. Then add 2 to 3 tablespoons of olive oil.
Cut two onions in half and cut carrots into 2-inch slices. When the oil in the pot is very hot (but not smoking), add in the halved onions, browning them on one side and then the other. Remove the onions to a plate.
Throw the carrots into the same very hot pan and toss them around a bit until slightly browned, about a minute or so.
Place the meat in the pan and sear it for about a minute on all sides until it is nice and brown all over. Remove the roast to a plate.
With the burner still on high, use either red wine or beef stock to deglaze the pan, scraping the bottom with a whisk to get all of brown bits.
Place the roast back into the pan and add enough beef stock to cover the meat halfway. Add in the onion and the carrots, as well as herbs.
Put the lid on, then roast in a 275F oven for 3 hours (for a 3-pound roast). For a 4 to 5-pound roast, plan on 4 hours.
