In addition to my default ground beef recipe, a.k.a. chili (with 2lbs this time) I made fillet mignon.
The fillet mignon was labeled as beef tenderloin, since it is basically steaks cut from the tenderloin. The package had 2 in it. I took it out before we went jogging. About an hour latter I started cooking. Seasoned the steaks with kosher salt and black pepper. Put the cast iron pan on med high and let it get hot. Added a dash of olive oil. Seared the steaks for about 3 min per side. Took them off around 140F and let stand.
While the meat was standing, I deglazed the pan with some white wine. Then I added chopped onions. (I should have sauteed the onions before deglazing, but oh well.) Added some mustard, salt pepper, cream, meat juices and let it reduce.
Served the meat with the mustard cream sauce, asparagus, potato gnocci, and asian pears. The meat was actually around the recommended serving size (a deck of cards) and quite tasty. A success.
