Cooking can be as simple or complex as you like and even the basic act of frying meat can be packed with nuance (and hopefully flavour). We've previously covered in detail how best to handle steaks, but if you want a more visual and streamlined guide, this video from Tasty has the goods.
While a large variety of beef cuts exist, they can be split into two groups -- cheap and expensive.
The clip above explains how to get the most out of budget meats such as chuck and flap steaks, before moving onto your more pricier fare like the ever-delicious eye fillet (called a tenderloin in the US).
As a general rule of thumb, your cheap beef is best marinated, used in stews or as base of some sort. For your better cuts, you want to cook those properly on a cast-iron frying pan with simple seasoning -- you can get away with just salt -- so the natural flavour can do the talking.
