Top Tip for making Mustard and thyme roast beef
Remove the meat from the fridge about an hour before cooking to allow it to reach room temperature.
When it comes to how long you should cook roast beef for you need to decide how you’d like your meat to be when serving. Medium-rare, medium or well done? The rule is to calculate your cooking time based on 20 minutes per 500g and add 5 minutes per 500g to get the desired cook.
For medium-rare cook your roast beef for 20 minutes per 500g and for medium cook your roast beef 25 minutes per 500g and so on.
It’s best to cook your roast beef uncovered. This will allow the outside of your cut of meat to crisp and the insides to cook at a slower pace which is perfect if you want to achieve the medium-rare finish. You can use a meat thermometer to make sure your beef is cooked to perfection too.
Once your roast beef is cooked, you can cover with tin foil and leave to stand for around 15 minutes before cutting and serving. This will allow the meat to continue cooking slightly when out of the oven and keep the heat.
You don’t have to put water at the bottom of the pan or roasting tray when cooking roast beef. But some recipes recommend it, especially if you want to use the juices afterwards for homemade gravy. Add a cup or two of water at the bottom of the tray just before the cut of meat goes into the oven. You can also use wine or broth too.
