Grilled Flat Iron Steak with Chimichurri Sauce is something that would be great to make on a weekend when you feel like cooking on the grill. I discovered this cut of meat back when it wasn’t as well know or expensive as it is now, but it’s still a pretty good buy compared to most steak that’s suitable for grilling.

It was my butcher who recommended I try the cut of beef called Flat Iron Steak, telling me he was sure I’d like it. At first I thought this was just another name for flank steak, but I got interested when the butcher told me this cut didn’t need to be marinated. I got even more interested when he told me it was perfect for grilling. And I have been making this dish with Flat Iron steak for years now!

What is Flat Iron Steak?

The Flat Iron Steak is a long thin piece of meat, sometimes called a top blade steak because it comes from the top of the blade chuck roast. You can see more about Flat Iron Steak and how it got the name at Gourmet Sleuth. Under the label on the piece of meat I bought in 2007 before this cut was more well known it said, “You have just purchased a great new steak! The Flat Iron is cut from sections of larger roasts using a new cutting method. It is so tender, other than the tenderloin, you won’t find a more tender steak.”

What is Chimichurri Sauce?

Chimichurri Sauce is a South American condiment for beef that’s based on fresh herbs, garlic, and lemon juice or vinegar, and it’s sometimes called Argentinian Pesto. You can make it to taste, but we started with a generous amount of chopped cilantro and chopped flat-leaf parsley. Then Jake chopped up several tablespoons of finely-minced fresh garlic. This sauce is good on any kind of grilled meat, but it’s most well known for serving on beef.

What if You Don’t have an outdoor grill?

If you don’t have an outdoor grill, this can be cooked on a stove-top grill pan with ridges (affiliate link) or a George Foreman Grill (affiliate link) with good results.

(Scroll down for complete recipe, including nutritional information.)

  1. You can see from these nicely chopped herbs and garlic that Jake has great chopping skills, but you could also use a food processor.)
  2. We mixed the sauce together to let flavors blend while we cooked the meat.
  3. I used my homemade Montreal Steak Seasoning to season the meat, but you can use any steak rub you have on hand. 
  4. Let the steak come to room temperature while you pre-heat the grill.
  5. Cooking time will depend on the thickness of the meat, and how well done you like it, but I cooked mine not quite 12 minutes for medium rare.
  6. Be sure to let the meat rest for a few minutes before you cut it.
  7. Slice Flat Iron Steak against the grain and serve the sliced meat with Chimichurri Sauce.

Grilled Flatiron Steak with Chimichurri Sauce is wonderful for a special meal cooked on the grill.

Ingredients

  • 1 1/2 lb. piece Flat Iron Steak
  • 1 T Steak Rub

Chimichurri Sauce Ingredients:

  • 1/2 cup finely chopped cilantro leaves (about 1 cup before chopping)
  • 1/2 cup finely chopped flat leaf parsley leaves (about 1 cup before chopping)
  • 2 T minced garlic
  • 3 T fresh lemon juice
  • 2 tsp. red wine vinegar
  • 1 tsp. Aleppo pepper flakes (see notes)
  • 1 tsp. ground cumin
  • 1/2 cup olive oil

Instructions

  1. Take the steak out of the refrigerator at least 30 minutes before cooking, rub with steak rub, and let it come to room temperature.
  2. Wash cilantro leaves and parsley leaves and dry with paper towel or spin dry in salad spinner.
  3. Finely chop the cilantro, parsley, and garlic, either by hand or in a food processor with steel blade.
  4. Put ingredients into a bowl and add lemon juice, red wine vinegar, Aleppo Pepper (affiliate link) and cumin and stir to combine.
  5. Then stir in olive oil until mixture is well blended, and let sit at room temperature at least 15 minutes before serving.
  6. To cook steak, preheat gas or charcoal grill to medium-high heat. (You can only hold your hand there for 2-3 seconds at that temperature.)
  7. Put steak on grill at an angle. After about 3-4 minutes, or when you see nice grill marks starting, rotate 45 degrees and cook 3-4 minutes more on first side.
  8. Turn steak over and cook on the second side until the meat is done to your liking. (=
  9. I cooked my steak just under 12 minutes total for medium rare, but cooking time will depend on the heat of your grill, the temperature of the meat, and even the weather.
  10. I recommend using an instant-read meat thermometer (affiliate link) for best results on beef and cook to 130F for medium rare, which is the recommended doneness for this cut of meat.
  11. When meat is done to your liking, remove from grill and let rest for 5 minutes, then cut into thin slices across the grain.
  12. Serve hot, with Chimichurri sauce spooned over or on the side.

Notes

If you don't have Aleppo Pepper (affiliate link), just use a smaller amount of cayenne pepper.
