Steak Diane is a classic restaurant dish from the 1960s made with pan-seared medallions of beef tenderloin, sautéed mushrooms and a brandy cream sauce.
1lbbeef tenderloincut into 1/2-inch thick medallions
1/4cupheavy cream
2teaspoonsDijon-style mustard
1-1/2teaspoonsWorcestershire sauce
3tablespoonsbutterdivided
1smallshallotminced (about 1 tablespoon)
2clovesgarlicminced
8ounceswhite button mushroomssliced
1/4cupbrandy(or cognac)
Salt and freshly ground black pepper
2teaspoonschopped fresh parsley
Instructions
Season the beef medallions on both sides with salt and pepper.
Combine the cream, mustard and Worcestershire in a small bowl until smooth and set aside.
Melt 1 tablespoon of the butter in a large skillet over medium-high heat and swirl to coat the pan. Add the beef medallions and sear briefly ~ 45 seconds per side. Transfer the meat to a plate and cover loosely with foil.
Add the remaining 2 tablespoons of the butter to the pan. Add the shallots and garlic and sauté until softened, 1 minute. Add the mushrooms, season with salt and pepper and continue cooking, stirring continually, until they are lightly browned, 3 to 4 minutes.
Add the brandy to the pan and ignite (see notes). As soon as the flame dies, stir in the cream mixture. Immediately return the beef medallions to the pan along with any juices that have accumulated on the plate.
Using tongs, turn the medallions several times to coat with the sauce and heat through (no more than 1 minute for rare).
Transfer the medallions to a serving plate, top with the mushrooms and sauce and garnish with chopped parsley.
Notes
If you don't want to ignite the brandy, simply simmer the mushroom-brandy mixture until the liquid is reduced by about half - about 2 minutes.
