Flavourful Beef Rump Steak with Onion Sauce
What is rump steak?
Rump steak or round steak is a very lean cut of meat from the hindquarters or backside of a cow. Because it has a relatively low fat content, it is not as tender as sirloin or tenderloin but still tasty and less expensive.

The meat of a rump steak is dense with a robust flavour, and because there is no fat at all, it will dry out faster and leave a drier texture if not cooked properly.
Best practice to cook rump steak
Use a heavy-based, non-stick pan which retains heat very well. Use a tiny splash of oil and get both the pan and oil extremely hot before adding the meat. The oil should almost be at smoking point to achieve a delicious brown crust and seal the flavours into the steak.
Basting it with additional melted butter during the cooking process will keep it juicy, and we advise limiting the cooking time to avoid a dry piece of meat. Prepare a rump steak correctly and it will be a delicious and budget-friendly option.
