I've always done a white wine vinegar, soy sauce, olive oil, garlic powder, onion powder base with whatever I'm feeling like throwing in there on top.

24 hours in the fridge, 2 hours on the counter.

Then I do a super hot cook on both sides on the grill to medium rare and pull it. Rest, cut against the grain, etc. But I'm looking for tips because I always feel it's still a bit tough.

Should I add some enzymatic to the marinade like a pineapple juice? Should I try sous viding then flash searing like I usually do with other cuts?

And if it matters, this won't go in tacos. Just want to cut it up on a board, drizzle some chimichurri on top and just let guests graze, along with other food we put out.

I like to marinade flank steak in a carne asada style marinade.

I grill it to about medium, slice it thin against the grain, and then throw it into a tortilla with some chimichurri. Comes out great.

How long do you marinade and in the fridge or room temp?

How do you cook it?

After extensive googling, I think I'm going to try and soak it in seltzer water for 30 or so minutes before drying and putting in a traditional marinade with lemon juice, vinegar, soy sauce, olive oil and seasonings. Seltzer trick apparently works pretty well.

Olive oil, minced garlic, salt, pepper, whole rosemary, marinate for four hours. Cook high heat until medium rare takeoff. Let’s sit for 15 minutes. Cut and serve it is unbelievable.

Flank steak sucks. One of my least favorite cuts. Skip it and get skirt.

Keep it simple. Jaccard tenderizer. Marinade it Allegro or Dales for a couple of hours. Throw it on the grill. On the hot side for a good sear. Warm side til medium rare. Rest it then slice it thin at a 45 deg angle.

I buy flank steak from Fresh Market on Thursday because they run their USDA Prime on sale that day for $9.99. I just put some salt and pepper on it, let it rest for 30 minutes, then grill it over high heat. It’s never tough. The reason I don’t marinate it in anything is I like the simplicity of it because flank steak has its own unique flavor. I’ll dip it in some Chimichurri while I’m eating it.

Soy sauce, sugar, ginger, garlic, sesame oil in a bag then into the souse vide.

Boil the bag juices and add a little corn starch to slightly thicken it. Slice and serve with sauce on top.

As sacrilegious as this sounds, Google Rachel Ray Korean flank steak, someone brought one to a party we had years ago, and it's pretty much the only marinade I use for flank steak to this day.

We just had a block party and I did two for the party and they were gone quick

Try a flat iron steak, a few years back it was hard to find but now it's more popular.

I just cook on griddle and when done add vegs. and in a few minutes you have a meal.

I usually do a soy/balsamic vinegar mix.

Then I reduce the leftover marinade into a sauce.

I have a 60 day dry aged flank as part of a larger meat order from a grass fed farm. Not worried about quality of the meat.

I appreciate all of the tips, gonna give some a go tonight.

Fajita marinade wife loves

3 cups pineapple juice
2 cups soy sauce
1 cup water
2 limes juiced

Marinate at least 2 hours but no more than 4 hours

Season with fajita seasoning you like. Paul Prudhomme Fajita Magic is actually pretty damn good.

Cook to medium rare and rest for 5-10 minutes. Slice thin and service with tortillas and fixings. It won't make the rest of the night.

1/2 cup lime juice
1 tbs apple cider vinegar
1/4 cup olive oil
1 tbs salt
1tbs black pepper
1 tsp garlic powder
1 tsp onion powder

Blend it together and pour over the flank steaks.

It's delicious.
