    Why You’ll Love this Recipe

    With traditional cooking methods like grilling, pan-searing, or broiling, there’s a very small window of the perfect doneness when making flat iron steaks. If you miss that window, the meat will become tough and chewy. 

    Sous vide cooking guarantees the result and ensures the steak is perfectly cooked by using precise temperature control. It also produces the meat with even doneness edge-to-edge.

    What is sous vide? It’s a French cooking technique where the food is vacuum-sealed in a bag, and then cooked for a long time at a precise temperature in a warm water bath. 

    Ingredients

    Sous vide flat iron steak ingredients on the counter.
    • Flat Iron Steak: This cut is considered to be very tender, second only to filet mignon in tenderness. It comes from the top blade which has a lot of flavorful marbling with uniform thickness, and is less expensive than other tender beef cuts like rib eye or New York strip steak. This particular cut is flat-looking with great flavor, similar to flank steak, skirt steak, and hanger steak. 
    • Olive Oil: Regular olive oil works the best for this recipe. Avoid extra virgin olive oil as it has a lower smoke point.
    • Salt & Pepper: I used coarse salt, but you can use regular table salt or sea salt. Freshly ground black pepper works the best.
    • Garlic Powder:  I used garlic powder for this recipe, but you can also use freshly minced garlic.

    How to Make Sous Vide Flat Iron Steak

    Sous Vide Flat Iron Steak recipe: step 1 and 2 photos.

    1. Set the Sous Vide Precision Cooker to 135°F (57°C) for medium-rare doneness.

    2. Season the steak with salt, pepper, and garlic powder.

    3. Place the seasoned flat iron steak in a zip-lock bag and vacuum seal it using the “water displacement”  technique. (You can use a vacuum sealer if you have one.)

    4. Place the bag in the sous vide water bath and cook for 2 hours.

    5. When the timer goes off, remove the bag from the water and transfer it to an ice bath or the refrigerator. Let it chill for about 10 minutes. Pat dry the flat iron steak with paper towels. Add more seasoning if needed. (It’s important to wipe off any extra moisture as it inhibits proper searing.)

    6. Then grill or sear for about 1 minute per side, just to caramelize the outside.

    Flat Iron Steak Seasoning/Marinade

    A simple seasoning made of salt, pepper, and garlic powder can bring out the best natural flavor of the flat iron steak. Alternatively, flat iron steak is also a good candidate for a marinade as it’s relatively thin, and the flavor can penetrate into the meat easily. 

    Pro Tips: It’s important to season generously before sous vide cooking for the best result! 

    Sous Vide Flat Iron Temperature and Time

    I recommend cooking flat iron steak at 135°F (57°C) for medium-rare doneness. If you’d like to have a tender, juicy flat iron steak, don’t cook the meat past medium doneness. If you’d like to try other temperatures, follow the chart below:

    Steak DonenessTemperature  
    Rare125°F (52°C)
    Medium Rare135°F (57°C)
    Medium140°F (60°C)
    Medium-well155°F (68°C)
    Well Done165°F (73°C)

    Flat iron steak requires longer cook time than most other tender cuts, and I recommend cooking it for 2 hours. 

    Pro Tip: It’s fine to leave it in the warm bath for an extra 30-60 minutes. But avoid cooking it for too long as the texture could become mushy.

    How to Vacuum Seal the Steak without a Vacuum Sealer?

    If you don’t have a vacuum sealer, a regular zip-top bag works well with this recipe. The trick is called water displacement technique: just place the seasoned steak in a zip-top bag, and seal all but one corner of the bag. Slowly place it into a bowl with cold water, making sure everything below the zip-line is covered by water. Then seal the rest of the bag (You can watch the video in the recipe card for a visual tutorial).

    Can I Sous Vide Frozen Flat Iron Steak? 

    Yes! Follow the same instruction and cook the frozen steak 30 more minutes in the warm water bath.

    Ingredients 

    • 1 pound flat-iron steak
    • 1/2 teaspoon kosher salt or to taste
    • 1/4 teaspoon black pepper or to taste
    • 1/4 teaspoon garlic powder
    • 1 tablespoon olive oil

    Instructions 

    • Add water to the sous vide container or a large pot, and set the Sous Vide Precision Cooker to (135°F/57°C) for medium-rare doneness. If you’d like to cook to other doneness, see the temperature chart in the post above.
    • Season your flat iron steak generously with salt, pepper, and garlic powder.
    • Place the seasoned steak to a zip-lock bag.
    • Seal all but one corner of the bag, and slowly place it into the water bath. Make sure everything below the zip-line is covered by water, and push the air out. (If the water is already heating up, you can use a kitchen tong to push the bag into the water). Then seal the rest of the bag. (This technique is called “water displacement method”).
    • Lave the vacuum-sealed bag in the sous vide water bath. Make sure it is fully submerged.
    • Cook for 2 hours.
    • When the timer goes off, remove the bag from the water bath and transfer it to an ice bath (or refrigerator). Let it chill for about 10 minutes.
    • Remove the steak from the bag and wipe off the moisture with paper towels. (Make sure to pat dry the surface completely.)
    • Season with more salt and pepper if necessary.
    • Place the cast-iron skillet or grill on medium-high heat, and add olive oil. Once hot, add the steak and sear about 1 minute per side. (If you use grill, you can brush the oil on the steak).
    • Slice against the grain and serve immediately.
