Filet mignon has a reputation for being the fancy steak, but it is secretly one of the most weeknight-friendly cuts you can cook at home. It is small, it cooks fast, and it loves a simple game plan: dry it well, season it well, sear it hard, then butter-baste like you mean it.
Now, about that “tender and springy” vibe. Filet is naturally tender, but the texture you are actually chasing is pillowy in the middle with a little pleasant resistance when you bite. Not chewiness, not toughness. Just that juicy, steakhouse-style bounce that lets you know you nailed the temp. That comes from two things: (1) not overcooking it, and (2) letting it rest so the juices stay put instead of running all over your cutting board.
This recipe leans into bright, cozy steakhouse energy with a quick pan sauce that is basically: drippings + butter + a hit of acidity. It is low drama, high reward, and yes, tasting as you go is encouraged.
