    1 hr 35 mins


  1. Combine the olive oil, whiskey, soy sauce, green onion, garlic, pepper, parsley, thyme, and rosemary in a large, sealable plastic bag; seal and shake to mix. Add the steaks to the marinade. Seal the bag, squeezing out as much air as possible. Refrigerate at least 1 hour. Remove steaks from marinade; discard the marinade. Allow the steaks to come to room temperature before cooking.
  2. Preheat an outdoor grill for medium-high heat and lightly oil the grate.
  3. Cook the steaks until they are beginning to firm and are hot and slightly pink in the center, 6 to 7 minutes per side. An instant-read thermometer inserted into the center should read 140 degrees F (60 degrees C). Cover the meat with two layers of aluminum foil and allow to rest in a warm area for 10 minutes before serving.

I went less on the oil, more on the whiskey, and more on the garlic. Boiled the left over marinade and put mushrooms and onions in it for a steak topping. The guys are still talking about it today! Very good recipe!!! Will be making again!!!!

Flat iron steak is a staple in my kitchen but this was the least flavorful marinade I've ever used. I will not make it again. I followed the recipe exactly.

I used this marinade last night with just a few changes. Used 1/4 cup oil with 2/3 cup of the whiskey. I also added fresh herbs as I have them growing in my garden and a low sodium soy. I chopped 2 green onions and used 2 cloves minced garlic. I was in a hurry so I could not marinate for I let it sit in a freezer bag for an hour at room temp. Perfection!! The meat was tender and very flavorful. The extra whiskey really gives it a buttery soft taste and you can actually taste the whiskey. I hate recipes that use so little of the liquer you never really taste it at all. This way worked best. I then took the left over marinade and used it to deglaze a pan of sauteed mushrooms and onions to make a side dish. It was awesome. Will be using this all the time now for flat iron steaks. Thanks so much!

This recipe was great . . . getting the Flat Iron Steak was KEY. I think next time I will reduce the oil a little bit and increase the whiskey. Thanks for sharing!

I marinated this for about 4 hours in the fridge. Unfortunately, I overcooked the meat to well done. Expecting the meat to be a little tough, I was pleasantly surprised that it was quite tender. Will make this again, but I will watch the time on the grill.

Has a bite to it! People who don't like spicy food probably won't enjoy it as much as those of us that do. Very good and different option because I was looking for something different from sweet-salty or tex-mex.

I loved this and have made it twice. The changes I made were to use a lot more whiskey, marinade it for a day or two, and to use the oven (since a grill was not available.) I cooked it at 350 degrees for 20-25 minutes. I also used Flank Steak since I did not have Flat Iron available. I am hoping to try this with Flat Iron the next time I cook it. Everyone loved this, I used it for Christmas.
