Flat Iron Steak with
Red Wine Sauce
Sous Vide and Grill methods
Serves: 6
Difficulty: Easy
Sous vide temp: 131
degree F; Time: 5-12 hours
Steak,
cooked sous vide, is the most exciting advancement in carnivore cooking! Flat
iron steak, my favorite cheap steak, is cut from the chuck blade roast – the
shoulder of the cow. That’s right, this is a piece of a chuck roast. It grills
well on its own, but after several hours tenderizing in the sous vide, it cuts
like a filet mignon. Sous vide precision cooking offers unparalleled control
over the results of your steak, letting you very precisely cook the steak to the
level of doneness that you prefer. No
guesswork or poking with a thermometer, no cutting and peeking, no jabbing with
a finger – just perfect results each and every time. Finally, sous vide
offers results that are not attainable by cooking with traditional methods.
With standard high heat cooking, you develop a temperature gradient within the
meat. The very center, where you shoved the thermometer, may be perfectly
medium rare but the steak will be increasingly more well done as you approach
the exterior. With sous vide, the steak is evenly cooked from edge to edge. I
added a simple red wine sauce to accompany the steak. But, it truly can stand
on its own.
- 3 (1-pound) flat iron steaks
- Kosher salt, Freshly ground black pepper
- Fresh herbs - optional
- 1 Tb canola or vegetable oil
- 3 Tb olive oil
- 6 Tb cold unsalted butter (divided)
- 1 onion, thinly slice
- 1 Tb minced fresh garlic
- 1 tsp dried oregano
- ¼ C tomato paste
- 2½ C dry red wine (use wine you would drink)
Start by
trimming the flat iron if your
butcher has not done so. Season steaks with salt and pepper. Add aromatics
if you wish – a mix of oregano, thyme, parsley for example 1-2 sprigs per
steak. See below for sauce preparation, which is the same for both methods of
cooking the beef.
For
traditional barbeque
Prepare
grill to medium-high heat. Season as above and sprinkle steaks with 3 TB olive
oil. Grill to desired doneness, about 5 minutes per side for medium rare.
Transfer steaks to a cutting board. Tent with foil and let stand 10
minutes. Be certain to cut across the
grain before serving.
For sous
vide
Preheat the
water bath to 131 degree F – for medium rare, 121 degree for rare, 135 degree F
for medium, 156 degree F for well (heaven forbid!!!).
Place the
steaks in their individual zip lock bags sealing by displacement method. To do
this, slowly lower your bagged steak into a pot of water letting the pressure
of the water press air out through the top of the bag. Once most of the air is out of the bag,
carefully seal the bag just above the waterline. Alternatively, seal the bag
using a vacuum-sealer. Drop the bags in the water bath. If properly sealed, the
steak should sink or clip to side of pot. Cook 5-12 hours.
After
you take the food out of the pouches pat it dry, either with paper towels or
clean kitchen towels. I tend to dry it off 5-10 minutes before I will sear it,
allowing the remaining moisture to evaporate and the meat to cool slightly. The
goal of post sous vide browning is to create the crust while heating the
interior of the food as little as possible. The main keys to accomplishing this
goal are dry foods, high temperatures, and short times. Moisture that is on the
surface of the food will prevent it from browning, increasing the cooking time
needed, and potentially heating the food further. Place a heavy cast ion or
stainless steel skillet with 1 TB vegetable or canola oil over the hot burner
and preheat skillet until it starts to smoke. Gently lay the steaks in the
skillet. If desired, add a Tb of butter and/or aromatics like whole thyme and
rosemary sprigs with leaves still attached, sliced shallots or crushed whole
garlic cloves. After 15-30 seconds, flip the steak so that the second side
comes in contact with the pan. It does not need to rest after cooking by sous vide.
Red
wine sauce
Melt 2 Tb of butter in a heavy large
saucepan over medium-high heat. Add onions
and sauté until tender, about 5 minutes. Season with salt. Add the garlic and oregano and sauté until
fragrant, about 30 seconds. Stir in the tomato
paste and cook for 2 minutes, stirring constantly. Whisk in the wine. Simmer until the sauce reduces by
half, stirring occasionally, about 10 minutes. Remove skillet from the
heat. Strain the sauce into a small
bowl, pressing on the solids to extract as much liquid as possible. Discard the
solids in the strainer and return the sauce to the saucepan and bring back to a
slow simmer. Cut remaining 4 Tb butter
into small chunks and whisk in the sauce a little at a time. Season the sauce,
to taste, with salt and pepper.
Final prep
Serve
the flat iron steaks, sliced, with red wine sauce alongside. This is one great meal – turns that tough
inexpensive cut of beef into a gourmet treat. Try it as soon as possible.
This sous
vide timing and technique works well with skirt steak, flank steak, flat steak
and other tough steaks that you normally cut against the grain to make
tender. I would not use the longer
cooking times with loin steaks – New York strip, ribeye, and tenderloin –
because they do not have much connective tissue and would not benefit from the
prolonged cooking time. For loin steaks, go with 1-4 hour maximum cooking time
depending size of steak.
