A topside roast is a cut of beef, most commonly sold in the UK, taken from the upper hindquarters of a cow. If cooked correctly, the meat of a topside roast is succulent and flavourful. To cook a beef topside roast, you need a few basic seasonings and approximately an hour for preparation and cooking. A basic topside roast recipe is for a 0.907 to 1.36kg. roast, but you can alter it to suit whatever size cut you have on hand.
Preheat your oven to 149 degrees Celsius.
Combine the dried mustard, soy sauce and vegetable oil in a small bowl. Stir with your fingers to blend the seasoning mixture evenly.
Rub the seasoning mixture over the surface of a 2 to 3lb. topside roast in an even layer. Place the rubbed topside roast into an ungreased baking pan.
Cook the roast uncovered for 40 to 60 minutes, or until it reaches an internal temperature of at least 57.2 degrees Celsius.
Remove the roast from the oven and let stand uncovered for 15 minutes before serving.
As a rule, bake a topside roast at 149 degrees Celsius for 20 minutes per pound.
