Instructions

Step 1: Preheat oven to 325°F. Rub 3 lbs British beef roasting joint with 3 tbsp olive oil, 2 tsp sea salt, and 1 tsp freshly ground black pepper, then place in a roasting pan.
Step 2: Arrange 4 medium peeled and chunked carrots, 3 medium peeled and chunked parsnips, 2 large quartered onions, and 6 whole peeled garlic cloves around the beef; tuck 2 sprigs of fresh rosemary on top.
Step 3: Roast uncovered for 2.5 to 3 hours, basting occasionally with pan juices, until the internal temperature reaches 135°F for medium-rare.
Step 4: Remove beef and vegetables to a platter, cover with foil to rest; pour off excess fat from the pan, then place the pan over medium heat.
Step 5: Add 1 cup beef stock and 1/2 cup red wine to the roasting pan, scraping up browned bits with a wooden spoon; simmer for 8 minutes until the sauce thickens and coats the back of a spoon.
Step 6: Slice the beef thinly and serve with the roasted root vegetables and pan sauce spooned over.
