Ingredients

• 1 (2-pound) boneless beef chuck roast

4. Rub the roast with olive oil, rosemary, thyme, steak seasoning, black pepper, and minced garlic.
5. Put the roast in a roasting pan or Dutch oven. Pour the saved beer around the meat.
6. Add the red potatoes around the roast. Sprinkle them with a bit of salt and pepper.
7. Cover the pan with a lid or foil.
8. Roast in the oven for about 3 hours, or until the beef is tender and cooked through.
9. Remove from the oven, let the beef rest for 10 minutes, then slice. Serve with the potatoes and the juices from the pan.
