Easy Oven Roast Beef with Root Vegetables and Gravy

Roast beef was traditionally served as Sunday night dinner in many households. Top Sirloin tends to be more moderately priced than Prime Rib and is lean, yet flavourful, with enough marbling for juicy tender roast beef. Use a meat thermometer to cook your roast to the doneness that you like the best – without overcooking it! NOTE: ‘Time-to-cook’ figures are rough guidelines only as cook time is dependent on so many factors such as oven and thermometer accuracy, starting temperature of roast, roast shape and cut. A good thermometer is one of your best kitchen investments.
