Look for center-cut filets that are evenly thick. 1.5″ minimum is the sweet spot for thickness. Anything thinner overcooks before you get a good crust. Tapered tail pieces cook unevenly, and you'll end up with one end medium-rare and the other well-done. Choice grade is perfectly fine here; filet is already so tender that the difference between Choice and Prime is smaller than with fattier cuts like ribeye. Tie each filet with butcher's twine around the middle to keep its shape during cooking. It takes 10 seconds and makes a real difference for even cooking. Filet keeps 3–4 days in the fridge from purchase if it's wrapped tight and stored in the coldest part (back of the bottom shelf, not the door). If plans change, it freezes well for up to 4 months; wrap in plastic, then foil, and squeeze out all the air. Thaw overnight in the fridge.
Filet mignon is the most tender steak you can buy, but it's also the most unforgiving when it comes to overcooking. There's very little fat to bail you out. Once you push past medium it dries out fast and you've just ruined a $40 piece of meat. The good news is if you nail the sear, use a thermometer, and pull it 5°F early to let carryover do its thing, you're going to get a great meal. If you've ever wanted to try reverse-sear or sous vide, this is the cut to do it on. Uniform doneness matters more here than any other steak.
USDA recommends steaks reach 145°F with a 3-minute rest. Filet mignon is a whole-muscle cut. Bacteria only lives on the surface, which searing kills. Medium-rare (130°F) is the most popular doneness for filet and is widely considered safe. Always use a thermometer. This cut is too expensive to guess. Filet is thick so make sure you go through the side to the center with your probe.
