Filet Mignon with bone marrow butter is the ultimate in a decadent steak. The bone marrow butter adds a beefy goodness to an already great steak.
Filet Mignon with Bone Marrow Butter
I love a good steak. My dad really liked a good steak. I fondly remember him trying to grill a New York strip on a homemade gas barbecue built over 8″ lava rocks. The fat from the steak would create a flare up on the lava rock that could be seen from the moon. Fortunately, you don’t need to do it yourself. Any halfway decent barbecue will make a great steak. My favorite steak is Filet Mignon with bone marrow butter.
How to Buy Filet Mignon
I like to buy a prime, peeled tenderloin and cut huge 2″ to 2.5″ steaks out of the center. I trim off and save the head and tail sections for other great dishes, like breakfast tacos. Most butcher shops and markets sell two types of beef tenderloins, peeled and unpeeled. It cost a little bit more to get a peeled tenderloin but it’s worth it. An unpeeled tenderloin has a fair amount of extra fat, silver, and unusable meat that needs to be removed before cutting it into steaks. An unpeeled tenderloin may cost less, but there is a lot of waste. I would rather eat a steak than work that hard getting one.
There are two reasons to buy a peeled tenderloin rather than pre-cut steaks. First, you can cut nice thick steaks any size you want. Most cut steaks in my market are only 1″ – 1.5″ thick and that just will not do. I like my steak medium rare so I want a nice thick portion that is medium rare throughout. Remember, a steak will shrink on the grill. A 1.5″ steak out of the package will be only 1″ thick when cooked.
The second reason is that all of the steak that you cut from a peeled tenderloin will be consistent. Have you ever noticed a package of steaks where some of the steaks are light in color and others are very dark? Well those dark steaks are not good. They are called “heated” in butcher terms and that means the animal was stressed before slaughter. It does not make for a good steak. Just buy a tenderloin.
Roast the Bones
Most butcher shops and markets will carry bones that have been split lengthwise. Place them cut side up in a shallow pan and bake them for about 20 minutes at 375˚F. The bone marrow will transform from a firm, whitish material to something soft and gooey.
Let the bones cool a bit then scrape out all of the roasted bone marrow with a spoon and set aside.
Make the Bone Marrow Butter
After the bone marrow has cooled, mix it with the remaining ingredients for the bone marrow butter in a small bowl. Form a log on wax paper, roll it up and twist the ends. A sushi mat works wells for this task. Refrigerate the bone marrow butter for at least an hour before serving.
Grill the Steaks
Take your steaks out of the refrigerator and let them warm up a bit before grilling. Otherwise, you will have a 34˚F steak go on a 500˚F grill and by the time the inside reaches medium rare the outside will be far too done.
Another great way to cook steaks is sous-vide with a reverse sear. This is becoming more common in the restaurant business. Steaks are sealed with a little butter in food saver bags and pre-cooked to about 120˚F in a water bath. Since the water is also 120˚F the steaks will never go beyond that. Simply pre-cook a steak in a sous-vide bath then finish it on a hot grill to char the outside and get some nice grill marks. You will never overcook a steak again.
