cordero al asador

Ingredients

  • 1 Unit Young lamb 8-12kgs Ideally Patagonian
  • 2 Tbsp Coarse Salt
  • 1 Tbsp Black pepper
  • 2 Cups Red Wine
  • 1 Tbsp Garlic powder
  • 1 Tbsp Thyme
  • 2 Units Garlic cloves

Here are the key takeaways for the Argentine Patagonian grilled Lamb (cordero) on the spit:

  • Patagonian grilled lamb on the spit, known as cordero al asador or cordero a la cruz, is traditionally slow-cooked over open wood embers for several hours.
  • The lamb is butterflied and secured to a metal cross or spit, positioned at an angle near the fire rather than directly over flames.
  • Low and steady heat is essential. The cooking process can take 3 to 5 hours, depending on size, with gradual rendering of fat and crisping of the exterior.
  • Simple seasoning is traditional. Coarse salt is often the only seasoning, allowing the natural flavor of grass-fed Patagonian lamb to stand out.
  • Proper fire management is more important than constant flipping. The cook controls the distance from the embers rather than moving the meat frequently.

Argentine Grilled Patagonian Lamb on the Spit

Welcome to the ultimate Argentine Asado experience with our mouthwatering dish that so many people ask me for, “Argentine Lamb Grilled On The Spit”. The Spit in Argentina is referred to as “La Estaca”. This unique method of vertical cooking has been handed down through generations in Argentina, and when it comes to grilling a whole lamb, this is the ultimate method for creating a truly mouth-watering experience.

In Argentina, the Patagonian lamb on the spit is famously known as “Cordero al Asador,” or it can also be known as “Cordero a la Estaca”. Asador and Estaca can often be referred to as the same thing: the vertical spit.

In this recipe guide, we bring you the authentic flavors of Argentina as we slow roast/grill Patagonian lamb on the spit, ensuring a truly unforgettable grilling experience. This is a slow cook, so patience is required, but believe me the results are worth it!

What is the “Estaca” and why is the spit so celebrated in Argentina?

The “estaca” is a renowned cooking method that has become legendary in the Argentine grilling culture. The estaca cooking method is a vertical cooking method on a frame which often is a T section and is grilled and slow-roasted next to the flames. Sometimes we will add coals at the bottom of the estaca as supplementary heat.

The estaca is a celebrated cooking method in Argentina, as it takes time, and lots of patience is needed to cook on the vertical spit. This grilling method produces some of the most moist, juiciest, and rich in flavored meat.

Also, a key aspect of the Estaca method is that the juices from a piece of meat on a traditional grill flow in the direction of the fibers, downwards if the meat isn’t seared. When the fibers are not in line with the grill they are retained in the meat longer, adding to the moisture and taste.

Equipment

  • Vertical spit (Also known as "estaca")
  • Fire pit Safe place to build and maintain the fire
  • 30-50Kgs of quality fire wood Check our guide to quality wood for grilling or slow roasting

Ingredients
  

  • 1 Unit Young lamb 8-12kgs Ideally Patagonian
  • 2 Tbsp Coarse Salt
  • 1 Tbsp Black pepper
  • 2 Cups Red Wine
  • 1 Tbsp Garlic powder
  • 1 Tbsp Thyme
  • 2 Units Garlic cloves
  • 3 Units Sprigs of Rosemary
  • 2 Tbsp Olive Oil Extra virgen

Instructions
 

  • Step 1: Prepare the Lamb

  • Open the lamb fully by butterflying it so it lays flat.
  • Trim any excessive loose fat but keep most of it intact for moisture.
  • Pat the lamb completely dry.
  • Secure it tightly to the asador cross (Estaca) with the bone side facing the fire first.
  • Spray the lamb lightly with olive oil
  • Lightly season both sides with coarse salt and black pepper.
  • Step 2: Prepare the Fire
  • Use hardwood and build a strong fire to create steady embers, but primarily a good flame.
  • Allow the flames to die down a little before positioning the lamb.
  • You want consistent embers, and active flames.
  • Position the cross vertically at a very slight angle about 60–70 cm from the flames. You can put some embers at the base of the cross.
  • The bone side should face the fire first. The key is indirect radiant heat, not direct flame.
  • Step 3: Prepare the Salmuera
  • Warm the water slightly to help dissolve the salt.
  • Stir in the coarse salt until fully dissolved.
  • Add red wine.
  • Crush the garlic cloves and add them in.
  • Add thyme and rosemary.
  • Stir in garlic powder.
  • Finish with olive oil and mix well.
  • Let it sit for at least 20 to 30 minutes so the flavors infuse. This is not a heavy marinade. It is a light basting liquid used during cooking.
  • Begin Cooking: Start with the bone side facing the fire. Cook slowly for 2 to 3 hours without flipping.
  • Baste with Salmuera: After the first hour, begin brushing lightly with the salmuera every 30 to 40 minutes.
  • Flip the Lamb: Once the bone side is fully cooked and the meat has tightened, flip the lamb so the meat side faces the fire. Move it slightly closer to the heat. Cook for another 1 to 2 hours.
  • Final Crisp and Rest: Let the fire die down slowly,. In the final 20 to 30 minutes, bring the lamb slightly closer to the embers to crisp the outside. Watch carefully to avoid burning.
  • Remove from the cross and rest for 15 to 20 minutes before carving.

Notes

Patagonian lamb, also known as cordero al asador, is traditionally cooked over hardwood embers as well as the open flames. The key is indirect radiant heat and patience, not high temperature grilling.
An 8–12 kg young lamb is ideal for spit roasting because the meat stays tender and the fat renders slowly over several hours. Larger animals require longer cooking times and greater fire control.
The salmuera is not a marinade. It is a light basting liquid used during cooking to maintain moisture and enhance flavor while the lamb slowly roasts.
Bone side faces the fire first. This protects the meat from direct heat and allows the fat to render gradually before crisping the exterior.
Do not rush the cook. Traditional Argentine grilled lamb on the spit takes 3 to 5 hours depending on size and fire management. Consistent embers matter more than constant flipping.
Hardwood is essential for authentic flavor. In Argentina, woods like quebracho are common, but oak or other dense hardwoods work well outside Patagonia.
Internal temperature for tender lamb on the spit should reach around 85–90°C in the thicker shoulder sections for fall-apart texture.
Resting the lamb after cooking allows juices to redistribute and improves carving quality.

How to grill the Argentine Lamb step by step:

In this video, we take you through every step of the Argentine Lamb BBQ process, providing valuable insights and tips along the way. Here’s what you can expect:

1. Preparing the Lamb:

We begin by carefully selecting the finest Patagonian lamb and preparing it for the grill. Trim any excess fat and preparing a marinade or seasoning. Learn the art of seasoning the meat, marinating it to perfection, and ensuring optimum tenderness.

2. Setting Up the Spit:

Watch as we assemble and set up the traditional vertical spit (known as Estaca), getting it ready for the grilling process. We’ll share the techniques and equipment required to achieve the ideal cooking environment for the Argentine Lamb BBQ.

3. Preparing the Fire and Grilling the Lamb:

Once the preparations are complete, we place the lamb on the spit and slowly roast the lamb (ribs side to the flame) for between 3 and 4 hours. After the first side is done we will slowly rotate over to the other side, for around 1 hour depending on he color, cooking evenly and absorbing the smoky flavors from the hardwood.

4. Achieving the Perfect Taste with Salmuera:

Discover the secrets to achieving a beautifully caramelized crust on the lamb and a complex robust smoky taste to the meat. This is achieved by the one and only “Salmuera“. This flavor-intense brine is applied during the whole cooking process and is the culprit for the moist and smoky taste, it adds a delectable touch of perfection to every nibble.
