Ingredients

  1. 2 tablespoons red wine vinegar
  2. 2 cloves garlic, minced
  3. 1 tablespoon cracked black pepper
  4. 1 teaspoon dried rosemary leaves, crumbled
  5. 1 teaspoon dried oregano
  6. ¼ teaspoon kosher salt
  7. ¼ cup olive oil
  8. 1 ½ pounds flat iron steak
  9. 3 tablespoons softened unsalted butter
  10. 1 ounce crumbled blue cheese
  11. 1 tablespoon chopped fresh chives
  12. ⅛ teaspoon cracked black pepper

Instructions

  1. Whisk olive oil, vinegar, garlic, 1 tablespoon black pepper, rosemary, oregano, and kosher salt together in a bowl and pour into a resealable plastic bag. Add steak, coat with the marinade, squeeze out excess air, and seal the bag. Marinate in the refrigerator for 30 minutes.
  2. Preheat an outdoor grill for medium-high heat and lightly oil grate. Remove steak from the marinade, shake off excess, and discard remaining marinade. Allow steak to stand at room temperature as the grill warms.
  3. Meanwhile, mash butter, blue cheese, chives, and 1/8 teaspoon of black pepper together until combined; set aside.
  4. Cook steaks on the preheated grill until firm and reddish-pink and juicy in the center, about 5 minutes per side. An instant-read thermometer inserted into the center should read 130 degrees F (54 degrees C). Allow steak to rest in a warm place for 10 minutes before slicing thinly across the grain. Serve with a dollop of blue cheese-chive butter.

I didn’t have the ingredients for the butter, but we loved the steak by itself. It marinated for about 1-1 1/2 hours, and turned out spot on. Went well together with boiled corn and grilled asparagus and peppers. Will try it with the butter next time.

The marinade is awesome. The blue cheese butter on it was ok. I would stick to the marinade, add the butter and some garlic at the end and spoon it on. I did not like the blue cheese on the steak. A burger topped with it would have been better.

I tried this and loved it. I substituted filet mignon instead of the flat iron and didn’t marinate it, but only added salt and pepper. Since it was over 2 inches thick I cooked it an additional minute or two per side and instead of making the blue cheese butter dip I just had it plain. Except for the expensive meat this is a great recipe, I will try it again.

I just got done eating and it was excellent! The only change was a little bit more Blue Cheese in the butter and it was perfect! I will definitely be making this again!
Erica Yang
I will make it again. The blue cheese and chive butter is awesome.
Micheal Carr
I marinated the steak for 3 hours. Heated the grill to 425 and cooked the flat iron steak for 2 mins on each side. Steak was medium rare and tender; absolutely DELISH.
James Miller
I made it a couple days ago, so delicious. And the butter was such an added treat
Sean Frye
Yum!!! Simple and delicious, and a big hit with the hubs for Valentine’s Day dinner!
Jessica Pham
This is a delicious dish! My family really enjoyed it! I didn’t have chives for the bleu cheese butter, so I chopped up some scallions and added them to the mixture. It was the perfect topper for the steak. I’ll definitely be making this again!
Vincent Chavez
Husband loved it—he is still talking about it. Will make again, probably for guests, too!
David Franklin
It was great
Gregg Dixon
I pretty much follow the recipe, but marinade longer. Did it the first time on the grill, after that I put it on the smoker. It’s thin so it smokes very quickly, but the flavor the smoke adds was incredible. I highly recommend you try it if you have a smoker! I used plum wood simply because that was all I had on hand at the time.
Jeffery Fernandez
Very good, but I marinated it overnight.
Jason Whitaker
This was just an okay marinade. I did let the steak marinade for almost 2 hrs. and we still couldn’t really taste it. I’ll just stick to a little olive oil and salt and pepper. The blue cheese butter was really good, especially on bread. Thanks for the recipe.
Tammy Parks
This was great!! I did use sirloin instead I doubled the recipe, also 1/2 as much oregano, only because I don’t really like oregano other than those two things I really did not change anything else. All in all it was a really nice steak recipe with tons of flavor.
Michael Butler
Sorry to say we did not like the marinade at all. I ended up rinsing it off the meat after cooking and using the meat in a stir fry dish. The meat was very tender, though.
Michael Sanders
Very good marinade. Didn’t make the blue cheese butter.
Bonnie Cohen
Wonderful! Only change was to double all ingredients! Very elegant dinner!
Linda Jones
I made this tonight, I didn’t have a grill so I sautéed the steaks in the marinade over high heat. 4 minutes for the first side, 3 minutes for the second. Served with a side of French fries. It came out amazing!
Julian Jones
This was almost TOO good… I wasn’t prepared for all the flavor that comes with it. There were several ingredients in it that my boyfriend doesn’t like but I love (mainly the Bleu cheese) but I made it exactly as directed anyway. I waited for a comment after I gave it to him and in minutes his plate was cleared and he told me anytime I make steak in the future I should make it exactly like this. Fine by me!!
Cindy Conley
I loved this. It was very tasty!
