After several misfires over the last few years, I’ve given up with going out that night, and instead focus on lovely dishes we can make at home. Here is a classic date night meal—filet mignon in a red wine reduction.
What Is Filet Mignon?
Filet mignon is a steak cut from the tenderloin, a missile shaped muscle which lays beneath the ribs, right along the backbone. The tenderloin muscle is called “tenderloin” because it is just that, tender. It doesn’t get the exercise that would make it tough, like a shank or shoulder. It is also relatively lean.
How to Prepare Filet Mignon Steaks From a Beef Tenderloin
To prepare filet mignon, either you are going to buy filet mignon steaks already prepped, or a large beef tenderloin, from which you cut the steaks. If you are cutting steaks from a whole tenderloin, first decide if you are going to keep the chain muscle or not. The chain muscle is a smaller muscle that runs along the tenderloin. To make a classic filet mignon medallion shape, most people trim way this piece, but it is still part of the tenderloin cut and tastes great, although not quite as tender as the rest of the tenderloin, so keep it if you want. The steak we have prepared here includes the chain. (Here’s an excellent tutorial from Fine Cooking about trimming the chain and silver skin.) Trim away the ends of the tenderloin and cut away any silver skin. The thicker end of the tenderloin is best for filet mignon medallions. As you get closer to the thin end, that part can be folded and tied for a roast. Think about how well done you would like your steaks and how thick they are. If you want a thick steak and you like your steak rare, or medium rare, you’re in luck, this will be easy. Cut the tenderloin into 1-inch to 2 inch-wide steaks.
How to Butterfly a Thick Filet Mignon Steak
If you have a thick steak (2 inches or more) and you want your steak medium or medium well, then you may want to butterfly it first. If the chain muscle is still attached, you can make a lovely heart shape with the steak. Either cut will work with the following recipe—medallions with or without the chain, or heart-shaped butterflied.
If you have thicker steaks, you can butterfly them and cook on the stovetop as directed here, or you can sear them on the stovetop and finish them in a 350°F oven for 10 minutes or more, until the center of the steaks are done to your liking. You can use the finger test to test the doneness of your steak. Or you can use a meat thermometer inserted into the thickest part of the steak (120°F to 125°F for rare, 130°F to 135°F for medium rare, 140°F to 145°F for medium). Remove from the pan, loosely tent with foil and allow to rest while you make the sauce. Turn off the heat and wait until the wine has stopped bubbling. When it has, add the tablespoons of butter, one tablespoon at a time. Swirl each tablespoon into the sauce until it is completely incorporated before adding the next tablespoon of butter. Add salt to taste and serve the sauce with the steak. Sprinkle freshly ground black pepper over the meat when you serve it.
