We all know my love for lamb goes beyond even my love for pumpkin beers and thus I am sad to say I haven’t had it much recently because it is so expensive. But the other night, at a friend’s birthday party, I met a chef named Larry Shifrin. He told me how he cooks lamb and that it involves hitting it after it cooks with an herbs and garlic marinade. I had to do a double take when he said it and check his drink. He wasn’t slurring. He wasn’t listing. He was enjoying an adult beverage, but he was by no means drunk. “Marinating after the grilling,” I thought to myself. “That’s a new one for me.” I looked at him and said, “Larry, tell me more about this process.” And he did and I knew it wouldn’t be long before I would be trying this method. Exactly one week later, I made Grilled Lamb with a Post Marinade which is his with only a few minor tweaks.

Wait. Pre Marinade? I thought this dish was all about the post marinade? It is. But just because we’re doing a post marinade in this recipe doesn’t mean we can’t do a pre marinade too. I want to infuse the lamb with some flavor before I ever get to the herbs and garlic of the post marinade.

Combine the salt, pepper, oil, garlic, red wine vinegar and onion in a bowl and then go to work on the fresh herbs and garlic:

And put all the pre marinade ingredients in a bowl:

The quickest way to mix the pre marinade is not with a whisk, but with a lid. Slap the lid on and give it a good shake:

Toss the lamb into a plastic bag and pour in the marinade and refrigerate:

Obviously I only did this for a five bone rack, but there’s enough to coat two whole racks. Marinate for as little as two hours to over night.

How to Make Grilled Lamb with a Post Marinade

The following day, prepare the grill for a low fire and smoke the lamb indirect with charcoal (or burners lit) on one side and no heat on the other with the lamb on the side with no heat side:

If you are wondering what the hole is. My grill has a center piece that comes out of the grill grate so I can add more fuel or smoke wood. In this case I used a blend of soaked chips from my local grocery store (hickory, apple, cherry, and sassafras).

And when I say low heat, I mean low. 200F is the max you want to go here:

200F degrees

All you want to do is impart some smoke flavor but not cook them all that much. We will be searing at the end where a lot of cooking will take place, so go low and slow.

Now go prepare the post marinade for the grilled lamb as it will smoke for 45-60 minutes:

Grilled Lamb Post Marinade:

  • 1/4 cup olive oil
  • 1/4 cup red wine vinegar
  • 1/2 cup parsley
  • 1 tbsp thyme
  • 2 cloves garlic
  • 1/8 tsp crushed red pepper flakes
  • pinch of salt and pinch black pepper

I was a bit pressed for time, so instead of chopping all the ingredients, I used the food processor. I simply apportioned out the ingredients on a cutting board:

And I dumped them all in a food processor:

I smoked the lamb for a total of 55 minutes. When the meat began to firm up, I went for the sear. I did this totally by feel. If you don’t feel that confident to do that, use a probe or instant read thermometer and sear them when they hit 120 degrees internal temperature for rare to medium rare. For medium rare to medium, wait till they hit about 135-140.

Now it’s time to sear. To save a little time I cranked up a gas grill on my deck and seared the lamb there rather than adding coals and waiting for the charcoal grill to get above 500F:

Dont forget to sear the ends

Once the grilled lamb is nicely charred, bring it inside and place on a sheet of aluminum foil:

Ready for the Post Marinade

Then cover with the post marinade paste which is really, really GREEN:

Now seal it in the foil and let rest:

Resting is vitally important. When meat comes off the grill, the juices are in the excited state because of the heat. Cutting into the lamb right away will result in the juices rushing out onto the cutting board. But allowing them to rest means they can settle down and redistribute throughout the meat and ensure a juicy bite from start to finish. And for this recipe, it cooks the post marinade just enough to awaken the flavors without overcooking them. Also, while the meat rests and drops in temps, the juices and the heat of the meat will steam the post marinade. 

After 8 minutes, open the foil and not so green anymore:

Ready to serve

Notice how the bright green post marinade has darkened as it cooked and soaked up some of the sumptuous liquid fat (gold) on the outside of the lamb?

The question becomes, did I over or under cook the lamb since I went by feel alone? Well, since I always include a teaser shot at the top, and if you’ve already been to the site you know, that these are darn near perfect for me:

Grilled Lamb with a Post Marinade Recap

Herbs can have their flavor cooked right out of them, same as garlic, which is why many chefs toss the herbs in right before plating a dish. Essentially, that’s what I did here. This way the herbs and garlic cook for only a little bit, fully opening up the flavors and putting them on the plate (and subsequently in your mouth) at just the right time. I can’t quite explain how fresh the herbs and garlic were when I tore through these meat lollies in about 30 seconds. It’s like a misty spring morning in your mouth. All the flavors are at their fullest like a I harvested the herbs myself and ate them within minutes of removing them from the stem.  It was absolutely refreshing.

And if you’re wondering whether or not I had a well rounded meal. I’d say so. This Joel Gott Cab rounded out the meal nicely:

Have you ever grilled a actual lamb roast. My mother-in-law, in O’Fallon…you “know” them sorta from high school, cooks 2 roasts every Christmas. I thought of grilling or smoking one, but haven’t really found anything on how to do on a grill. Any idea’s…goat a hankerin’ for gyros…



I have not done an actual lamb roast. For me, lamb starts and ends with the rib racks. Those meat lollipops are proof God loves us! Not entirely sure who your mother in law is. But I’m wanting some gyros too right now!
