We've used this on flank steak and for fajitas. I passed the recipe to a friend who grilled it with London Broil for a dinner party. It was a huge hit for us and for my friend. We plan to try it next with shrimp.

Great recipe. Easy and quick to make. I used English steak instead of flank steak and ground thyme instead of fresh thyme. I will make this again and share this recipe with family and friends.

Very good. Flank is one of my favorite cuts of beef when cooked right and this marinade and sauce added great flavor without overpowering the meat itself. I did add some extra lime juice and didn't have a jalapeno on hand so I went without it. Served with the Quinoa and Black Bean recipe also on this site and the two went very well together.

This marinade rocks! I'm not really sure how some of the reviewers were only able to taste onion, unless they put too much in, but this stuff is great. I have used red, white, and yellow onion and only put a 1/2 an onion in each time. Kicking up the garlic and using a whole head really makes a difference as well. I have used this on steak and it was wonderful, but using it on chicken is amazing. I double or triple the recipe so that we have plenty to use as a sauce. Play around with the marinade, but the combo of fresh lime juice, cilantro, garlic, and some peppers for heat, make this a winner.

This is going to be one of our favorites from now on. I used large garlic cloves and doubled the cilantro, just because we love it, but otherwise followed the recipe exactly. It was wonderful sauce for the flank steak.

The marinade was awesome! I'm curious though why it specified Flank Steak. There was a lot left over and i'm thinking of cutting up tomatoes and turning it into a salsa.

I used lime zest and the juice of two limes for this one. What a hit !

We really liked this marinade and did not find it to be chunky or the meat tough at all. The flavor is surprisingly subtle, which is great for those who don't want to overpower the meat. We just ate the steaks as is, but I think next time I will probably use this for fajitas and add another pepper.

This is an excellent recipe for Flank Steak. To the reviewer who said it was too chunky - you obviously didn't puree the ingredients properly because the definition of puree is a thick liquid suspension made from cooked food ground finely. If Flank Steak is cut across the grain it won't be tough unless you overcooked it.

This marinade is a good start but it needs something more to give it a more complex flavor. All we tasted were onions and cilantro. Maybe it needs more honey since we couldn't even tell there was any sweetness at all. Way too chunky from the onions and garlic even after being pureed. Overall, not a bad start, it just needs something more - and why use corn oil when olive oil is so much better?

Yielded a very juicy, herby-tasting meat, quite good. Would suggest scoring the meat before marinating to allow it to penetrate further, and make sure you cut properly against the grain -- didn't do that and oops, that's a chewy meat for fajitas.

My family LOVED this marinade! Where I changed things: 1) I forgot to buy fresh thyme so I used 1Tbs of dried and 2) my limes were kinda small so I used three. Some of the reserved sauce is in the fridge and I'm thinking it would be good on veggie wraps this weekend.

Not only does it smell great but it tastes great too. I had friends over and they loved it.

Awesome recipe! We loved it. I used it for fajitas and it was excellent. The best fajitas I had ever made at home! I didn't reserve any of the sauce, just poured it all in the bag and let it marinate over night. The only change I made was that I didn't have any thyme.

really good. gave it 4 stars but with my addition`s1

Had a big party made this marinade with chicken breasts added some chillies and extra jalapenos also did half and half Cilantro and Garam Masala .....Everybody loved it!!!

There is nothing better than a flank steak grilled medium-rare on the BBQ but this recipe ruined an otherwise great piece of meat in my opinion. All we tasted was the onions and it make the meat tough. Will not make again.
