Most of the cost is standing rib roast (2 bones) ($26.54) and unsalted butter ($0.71). With oil, spices and staples already at home, the shop drops to about $28.98. Prices are estimated for the amount used, at average US grocery prices (November 2026).

Steps

1. Pat the roast dry. Mix the garlic, rosemary, olive oil, kosher salt and black pepper and rub it all over the meat. Leave the roast at room temperature for 1 hour.
2. Preheat the oven to 450°F (230°C) and set the roast bone-side down, fat up, in a roasting pan.
3. Roast for 20 minutes until the outside is browned and sizzling.
4. Lower the oven to 325°F (160°C) and roast for 60 to 75 minutes more, until a thermometer in the center reads 125°F (52°C) for medium-rare, or 135°F (57°C) for medium.
5. Lift the roast onto a board, tent loosely with foil and rest for 20 minutes; the temperature climbs about 5°F as it rests.
6. Pour off all but 2 tablespoons of fat from the pan. Set it over medium heat, melt the butter, whisk in the flour for 1 minute, then whisk in the beef broth, scraping up the browned bits, and simmer for 2 to 3 minutes until slightly thickened.
7. Carve the roast between the bones into thick slices and serve with the jus.
