Heat 3 tablespoons vegetable oil in a large Dutch oven over medium-high heat.
Sear the onions and carrots
Cut 2 large onions(chopped into 2 inch chunks) in half, and add them to the Dutch oven when the oil is very hot. Brown them on one side, then the other. Remove the onions to a plate.
Add 4 large carrots, and cook until browned too. Remove the carrots to a plate.
Sear the meat
Season the beef on all sides with 1 1/2 teaspoon salt and 1 teaspoon pepper, then sear on all sides until it is brown all over. Remove the meat to a plate while you deglaze.
Deglaze
Add 1 cup red wine (or beef stock if you prefer) to the Dutch oven and deglaze, scraping to get all the brown stuff off the bottom.
Cook the Pot Roast
Put the beef back into the Dutch oven and add 3 cups beef stock.
Stir in the onion, carrots, 2-3 medium potatoes, 2 sprigs fresh rosemary, 2 sprigs fresh thyme, and 2 bay leaves.
Put the lid on, then cook in the oven for 4 hours.
Remove from the oven break up the meat with a fork, and serve (with the gravy).
Notes
I cook pot roast at around 1 hour per pound of meat. So, if your cut of beef is larger or smaller than mine, adjust accordingly.What to do with leftoversStore in a covered container in the refrigerator for up to 4 days.
