Because blue and rare steak depend on surface browning, seasoning belongs early—before the sear. Salt helps draw moisture to the surface and then allows better browning if the steak is dried well. A simple approach—salt, pepper, and maybe a light coating of oil—lets the beef taste lead.
Pepper can burn if the pan runs extremely hot or if the steak sears too long. If you love pepper, consider adding it after searing or using freshly ground pepper sparingly. Garlic is similar: minced garlic can brown quickly and turn bitter.
For a bolder finish, some cooks add compound butter after cooking—then serve immediately. That keeps the steak’s core as intended while adding flavor on the outside. If you do this with blue steak, keep the butter light so it doesn’t melt into a puddle that changes the crust.
