How to Cook Flat Iron Steak


Flat iron steak
Salt and pepper (or your preferred seasonings)
Cooking oil (such as vegetable oil, or rapeseed oil)


Grill, stovetop, oven, or sous vide setup (choose your preferred method)


Choose Your Cooking Method:

Grilling: Preheat your grill to medium-high heat 204-232°C. Oil the grill grates to prevent sticking. Place the seasoned flat iron steak on the grill and cook for about 3-5 minutes per side for medium-rare. Adjust the time for your desired level of doneness.

Pan-Searing: Heat a cast-iron skillet or a heavy-bottomed pan over high heat. Oil your steak. Place the oiled flat iron steak in the pan and sear for about 3-5 minutes per side for medium-rare. Adjust the time as needed. You can also add a knob of butter and some garlic and herbs to the pan for extra flavour during the searing process.

Sous Vide (Precision Cooking): Vacuum-seal the seasoned flat iron steak in a plastic bag and cook it in a sous vide water bath set to your desired doneness temperature 54°C for medium-rare. After sous vide cooking, sear the steak briefly in a hot pan or on a grill for a nice crust before serving.

Checking Doneness (Optional but Recommended):

For precise results, use a meat thermometer to check the internal temperature. Aim for an internal temperature of 54-57°C for medium-rare or adjust to your preferred level of doneness.


Allow the cooked flat iron steak to rest for a few minutes before slicing. This helps retain its juices and ensures a more tender result.

Slicing and Serving:

Slice the flat iron steak against the grain into thin strips. This cutting technique enhances tenderness. Serve your steak with your favourite sides, sauces, or accompaniments.

Remember that the exact cooking times may vary based on factors like the thickness of the steak and the specific cooking method you choose. Using a meat thermometer is the best way to achieve your desired level of doneness. Enjoy your deliciously cooked flat iron steak!

Hot Tips

Preheat Your Cooking Surface:

Whether you're grilling, pan-searing, or broiling, make sure your cooking surface (grill, skillet, or oven) is preheated to the proper temperature before placing the steak on it. This ensures a good sear and even cooking.

Oil the Steak, Not the Pan:

For pan-searing, brush the steak with a light coating of oil instead of adding oil to the pan. This helps prevent smoking and ensures even coverage.

Get a Good Sear:

When searing or grilling, let the steak cook without moving it for a few minutes to develop a nice crust. Flip the steak only once during cooking.


Here are some drink options that pair well with flat iron steak:

Red Wine:

A classic choice, red wine is a natural companion to steak. Opt for a medium to full-bodied red wine like Cabernet Sauvignon, Merlot, Malbec, or Syrah/Shiraz. These wines have the structure and tannins to complement the richness of the steak.

White Wine (for a lighter option):

If you prefer white wine, a full-bodied Chardonnay or a white blend with some oak aging can work well with steak. While not as traditional as red wine, it offers a different but enjoyable pairing.


A cold, robust beer can be a great match for flat iron steak. Look for a dark ale, porter, or stout with malty and caramel notes. These beers can stand up to the steak's flavours. You can also consider a hoppy IPA if you enjoy the contrast of hoppy bitterness.


Classic cocktails like a Manhattan, Old Fashioned, or a Negroni can be delightful choices. The whiskey or gin in these cocktails complements the steak's savoury qualities.

Sparkling Water:

If you prefer a non-alcoholic option, sparkling water with a twist of lemon or lime can cleanse your palate between bites and refresh your taste buds.

Iced Tea:

A glass of unsweetened iced tea, perhaps with a wedge of lemon, can provide a refreshing balance to the steak's richness.

Bourbon or Whiskey:

Sipping on a high-quality bourbon or whiskey can be a sophisticated choice, especially if you enjoy the interplay of the spirit's complexity with the steak's flavours.

Coffee or Espresso:

A strong cup of black coffee or an espresso can be a surprisingly good pairing with steak. The coffee's bitterness can complement the beef's richness.

Red Sangria (for a fruity option):

If you prefer a fruity and refreshing option, red sangria with its mix of red wine, fruit juices, and chopped fruits can be a fun choice, especially for outdoor dining
