Filet Mignon

In the world of meat, filet mignon just might be royalty—and its place on the throne is very well deserved. With unbelievable tenderness and flavor, it’s a cut that satisfies the masses.

Arguably the most sought-after cut of beef, ButcherBox filet mignon is cut from the tenderloin and comes from grass-fed, grass-finished cattle. It’s a steak that’s buttery in texture and mild in taste.

Filet mignon requires a short sear over high heat, so it’s a great choice when you have limited prep time.
