Sirloin does not get enough credit. It is affordable, it cooks fast, and when you treat it right, it delivers that steakhouse bite with crisp edges and a juicy middle. The secret is not a complicated marinade or a 12 step sauce. It is a dry surface, a hot pan, and a quick finish with something that makes you pause mid chew and go, “Okay, wow.”
In this recipe, that “wow” is a light and fluffy whipped butter. It is not fussy. You whip softened butter with a little lemon, garlic, and herbs, then spoon it over the hot steak so it melts into the crust and turns the whole situation glossy and unfairly delicious.
This is relaxed cooking with big results. If your smoke alarm has opinions, open a window and invite it to dinner.
