For anyone looking for a unique roast beef tenderloin recipe, this South American cooking method is both simple and impressive. When paired with high-quality natural lump charcoal, the dish delivers an authentic smoky flavor that makes it perfect for outdoor BBQ gatherings.
In this guide, you will learn what lomo al trapo colombia is, how to prepare it step by step, and why choosing the best charcoal for grilling steak can make a big difference in the final flavor.

What Is Lomo al Trapo Colombia?
The name lomo al trapo colombia literally translates to “loin in cloth.” It refers to a traditional Colombian grilling technique where a whole beef tenderloin is coated with salt, wrapped in cloth, and placed directly into hot charcoal. Although this method may seem unusual, it is widely used in Colombia for cooking tender cuts of beef in outdoor barbecue settings.
The cloth acts as a protective layer, while the thick coating of salt forms a crust during cooking. This crust prevents the meat from burning and helps seal in the natural juices. When the cooking process is complete, the outer layer of salt is removed, revealing a perfectly cooked tenderloin inside.
Compared with other roast beef tenderloin recipe methods that rely on ovens or grills, lomo al trapo colombia uses the intense heat of charcoal to produce a bold smoky flavor and a deliciously tender texture.
Ingredients Needed for Lomo al Trapo
Preparing lomo al trapo colombia does not require complicated ingredients. The focus is on quality beef and a reliable charcoal fire.
You will need a whole beef tenderloin, coarse salt, a clean cotton cloth, kitchen twine, and a large amount of hot charcoal. The salt should be coarse enough to form a thick protective layer around the meat. The cloth must be natural cotton because synthetic fabrics can melt or burn during the cooking process.
Equally important is the charcoal. If you plan to buy charcoal for bbq, it is best to choose high-quality hardwood charcoal that produces steady heat. Many grillers recommend natural lump charcoal because it burns hotter and produces less ash, which helps maintain the ideal cooking temperature.
Step-by-Step Roast Beef Tenderloin Recipe
One of the reasons lomo al trapo colombia is so popular is its simplicity. Even though the cooking method looks dramatic, the preparation process is quite straightforward.
- Step 1: Prepare the beef tenderloin
Start by trimming the beef tenderloin if necessary. Keep the meat whole so it retains its natural juiciness during cooking.
- Step 2: Prepare the salt layer
Spread a clean cotton cloth on a flat surface and pour a thick layer of coarse salt onto it. This salt layer will help protect the meat during grilling.
- Step 3: Coat the tenderloin with salt
Place the tenderloin on top of the salt and cover the entire piece of meat with additional coarse salt. The salt layer should be thick enough to fully surround the beef.
- Step 4: Wrap the meat in cloth
Wrap the cloth tightly around the salted tenderloin and secure the bundle firmly using kitchen twine.
- Step 5: Prepare the charcoal fire
Build a large charcoal fire and allow the charcoal to burn until it is fully ignited and glowing red. Many grillers prefer natural lump charcoal because it produces high heat quickly.

- Step 6: Cook the wrapped tenderloin
Place the wrapped tenderloin directly onto the hot charcoal. If needed, cover it with additional hot coals so the meat cooks evenly inside the heat.
- Step 7: Grill and rest the meat
Let the tenderloin cook for about 30–45 minutes depending on its size. After cooking, carefully remove it from the charcoal and allow it to rest for several minutes.
- Step 8: Crack the salt crust and serve
Finally, cut open the cloth and crack the hardened salt crust. Inside, you will find a juicy, smoky beef tenderloin with a tender and flavorful texture.

Why Charcoal Is Essential for This Cooking Method
Charcoal plays a central role in the success of lomo al trapo colombia. Because the meat is placed directly into hot coals, the quality and heat stability of the fuel become extremely important.

This high heat is exactly what makes the technique work so well. The charcoal quickly forms a salt crust around the cloth while the inside of the beef tenderloin cooks slowly and evenly. For this reason, many barbecue enthusiasts consider lump charcoal the best charcoal for grilling steak and other premium cuts of beef.
