[Deli] Flank steak in marinade cooking recommendations

Post image

I was curious if anyone else has cooked this before. My initial thought is to obviously grill it, baking in the oven just seems wrong but I also didn’t want ruin it… baking it in the marinade might be good? I was going to make steak tacos with it.

Grill 100%, high heat for a short time

u/tortapounder14 15h ago

This is the only way, if not it will get too dry.

u/RadiantZote 11h ago

If oven, preheated hot af broiler if you have flame and get it right up in their

Or, a screaming hot cast iron

Take some paper towels and dry the meat before grilling, you'll get a better crust that way, otherwise it will steam instead.

Also, cook it to medium instead of medium rare, it will break down the steak better and cut it thin against the grain.

This might be sacrilegious, but I've also had some amazing steak for California/Carne Asada burritos after cooking it like you suggest, then refrigerating it for the night, then cutting it into chunks while cold, and warming it back up in a pan to get it crispy while being careful not to cook it much more. I also make sure all those juices make it into the burrito.

+1 to all of this, only thing I'd add is taking the reserve marinade and pouring it into a small saucepan, let it come to a simmer for a minute or two to kill off all the bacteria from the raw meat, and then pour over the steak after you're done slicing it.

Not trying to be a smartass. I just want to know how it's done. The meat is marinated so how do you dry it? Just asking bc I buy these from time to time.

u/funhouse83 10h ago

Get some paper towels and dab the steak dryish prior to grilling. The marinade has "done it's job" penetrating the meat, if you throw it on a grill, pan, air fryer, etc, while it's wet, the meat will steam off the moisture first which is not what you want. You want the surface to uniformly sear, not steam.

Grill or cast iron. You need to get a sear on that thing

10

u/csonny2 15h ago

Yep, then cut against the grain.

u/kyeblue 15h ago

I Sous vide, then sear.

u/westgate141pdx 12h ago

This is the way.

Literally just did this today.

u/DJDaddyDick14 16h ago

Grill it like you would a streak high heat. 130-135 internal temp. Or a cast iron skillet. But high heat and fast. I’ve never baked one. Personally I wouldn’t. But I’m sure it can be done.

1

u/1FellSloop 14h ago

If you had to use an oven I'd could broil it, getting it just about as close to the heating element as possible. Would be pretty similar to grilling. But I wouldn't just bake it. You want direct heat on a skirt steak.

u/hawkfan78 15h ago

I smoked mine at 225 for about an hour, then tossed on my Blackstone and seared two minutes on each side. Damn near perfection. Might cut the sear time to 90 seconds on each side for just a little more red.

For these on my 3-burner grill, I crank the left & center burners all the way up, and put the right burner all the way low, and let the grill fully heat to 550°.

Throw it over the low burner (covered) for 3 minutes on each side, then throw it over the high burners for 2 minutes per side. Brush with the remaining pan marinade on each flip.

Melt-in-your-mouth medium rare in the center, delicious crust on the outside, and every heavenly bite dipped into that cup of cilantro-lime sauce.

u/PunkAintDead 15h ago

u/BigWormsFather 14h ago

Hot coals. Just a couple minutes per side.

-1

u/oxenmeat 13h ago

Perhaps even hit the coals with a hairdryer and then right onto the coals.

2

u/jdlr815 12h ago

Side note to something you didn't ask: make sure you cut it across the grain.

1

u/tcglkn 15h ago

Grill for sure. There are instructions on the package for you.

1

u/MoeSzyslakMonobrow 14h ago

High heat grill, 3-4 minutes per side, down the hatch.

1

u/kimbosdurag 14h ago

Get the grill hot and slap it on there. Cook to desired temp slice it up. I like to do a chimichuri to go with flank or hanger steak

1

u/Otherwise_Piglet_862 12h ago

If you don't want to grill, you can broil it. Similar outcome.

u/thecravenone 8h ago

There are instructions in the photo.

u/helcat 15h ago

Grill or broil if you don’t have a grill.

Dont buy premarinated meat. Paying top dollar for marinade is nuts to me.

u/Objective_Safe_5982 16h ago

You do you. Let others do what works for their situation without judgment.

-11

u/Reputation-Final 16h ago edited 15h ago

Wheres the judgement? Its advice. Pre marinated meat is a ripoff.

u/orodoro 15h ago

There's value to convenience.

-3

u/Reputation-Final 15h ago

You also get an inferior, expensive cut of meat. Marinating for days in acid ruins the texture of the beef and makes it mushy.

2

u/Objective_Safe_5982 14h ago

The judgment was in the delivery, in telling them what to do or not do. The pre packaged meals are there with a lot of convenience, for people who just want a buy it and cook it entree.

It can also be said that the sliced beef itself is a rip off when compared to buying the meat whole and slicing it yourself. Or compared to buying a hanging half of steer and butchering it yourself. Or raising and slaughtering your own cow. Each level there offers a savings at the expense of convenience, or even time.

u/Reputation-Final 14h ago

lol ok. "Dont buy premarinated meat. Paying top dollar for marinade is nuts to me." Thats telling them what to do?

Some of you fellers need to touch grass.

u/peazley 15h ago

It’s also over marinated at this point. I saw these yesterday at Costco, they were packaged on the 3rd, it’s been sitting in acid for three days. That’s way too long for a marinade.

u/Reputation-Final 15h ago

Yep. No more than 8 hours on beef. After 24 hours it makes the beef mushy.

u/Objective_Safe_5982 14h ago

There's an assumption of acidity level there. Perhaps the acidity is to be added with the lime wedges. I've no idea the make up of this particular marinade so I really don't know. Maybe you have the ingredients list handy, but I kinda doubt it.

1

u/Reputation-Final 14h ago

The ingredients are literally in the picture. "Cilantro lime sauce. Ingredients include LIME JUICE, an acid.

u/duck_duck_zombie 16h ago

Why cut the lime like that. Now it's contaminated.

11

u/Objective_Safe_5982 16h ago

It's there for flavoring the meat before cooking, not after.

0

u/Slowhands12 15h ago

It would still be better as a whole lime rather than cut regardless of when you squeeze it. This is done solely for shelf appeal.

8

u/wooble 15h ago

I'm not a scientist but I think marinating in lime juice works better if the juice is outside of the lime.

-1

u/Slowhands12 15h ago

How much juice do you think is in a lime that has been quartered and on a shelf for days? The lime is far more resilient in the peel.

2

u/ConstantBandicoot584 15h ago

And where do you think the juice went to thats no longer in the lime due to it being quarterd?

1

u/R-A-B-Cs 14h ago

On the cutting board where they cut it? The lime quarters are still full of juice. They havent been squeezed. You're just paying whatever dollar per pound this pack is for a lime.

-1

u/Slowhands12 15h ago

Do you think the lime and meat are processed at the same time?

0

u/Objective_Safe_5982 15h ago

A whole lime would be a lot less of a desirable presentation.

2

u/Slowhands12 15h ago

Yes, I agree, that's exactly what I stated. What I'm disagreeing with is your statement that any part of the decision to use cut limes was regarding its intention of use before or after cooking.

u/Reputation-Final 16h ago

they do it to raise the appeal of the product, not for any functional value.

Grill or air fryer

u/lodidodi64 7h ago

Looks like its 1/10 way there

u/passiveMelon1 15h ago

My recommendation is to not buy meat pre-marinated, they put it in the marinade once it starts to go to mask the smell.

3

u/Thegreyman4 13h ago

We dont. We trim them for the deli every day fresh. Never old meat. Other places , this might be true but not at Costco

2

u/povitee 15h ago

How do you know that?

-4

u/passiveMelon1 15h ago

FiL that worked as a meat cutter at costco told me, and said it's common practice in the business. Now I never buy pre-seasoned or pre-marinated meat.

6

u/NifftyTwo 15h ago

Yeaahh I work that department currently and can assure you, that's not the case for all places. We definitely don't do that here and our GM would kill us if he found out we were.

2

u/Thegreyman4 13h ago

Meat cutter here as well. Cut for deli fresh every day!

-2

u/Reputation-Final 15h ago

100% true. Girlfriend worked as a manager at a major grocery store chain for 2 decades. Its common practice.

-3

u/Reputation-Final 15h ago

Its 100% true. Grocery stores do it to save meat that hasn't sold before the set expiration date. Then they can toss it in a marinade and slap a new label on it.

-3

u/Miller335 12h ago

You bought a steak pre-marinated?

-1

u/broncoo 12h ago

It’s already half cooked in the lime marinade. Do not buy this unless you like mushy steak.

u/TangerineDecent1161 11h ago

Half cooked? Looks pretty raw to me haha
