Today we’re firing up the coals to make Stuffed Lomo Al Trapo, also known as a twist on the Salt-Crusted Beef Tenderloin, cooked in a wine-soaked dish towel. Yes, you read that right!

In Colombia, roasting meat in a cotton dish towel is a tradition. When you first place the red wine-covered tenderloin package on the coals, you may wonder if it’s going to turn into something presentable for your special occasion table. But indeed it does!

This savory creation, made with layers of pounded whole beef tenderloin, seasoned mushrooms, and spinach, is truly a showstopper. After cooking, a vinaigrette made with charred bell pepper and onion, levels up the flavors and visual appeal of the rustic-looking beef log even more.

Why You’ll Love Stuffed Lomo Al Trapo

Cooking meat wrapped in a wine-soaked dish towel is not for everyone, but I think it’s genius. The cotton creates a moisture barrier that leads to a nice and tasty seasoned salt crust.

The cooking time for this very easy recipe is relatively fast. After about 45 minutes of prep, you’ll have your entire tenderloin with a salty crust ready to slice in about an hour. 

It’s such a killer presentation of the delicious tenderloin meat, making it the perfect dish for special occasions such as Christmas Eve or Christmas dinner.

Salt Crusted Tenderloin Ingredients

  • The Cut of Meat – Stuffed Lomo Al Trapo comes together with one of my favorite cuts of meat, the tender beef tenderloin.
  • The Filling –  Spinach, mushrooms, and my Bourbon Prime Rub are the three simple ingredients that provide a delicious flavor contrast to the juicy meat.
  • The Trapo – Red wine, kosher salt, and a simple cotton dish towel create the wrapper for this juicy tenderloin log.
  • Charred Salsa VinaigretteChampagne vinegar, olive oil, parsley, and some fresh minced garlic are the fresh and flavorful ingredients that make the grill-charred red bell pepper and sweet onion so fricken delicious. 

Now, let’s get cooking!

How to Make Stuffed Salt-Crusted Beef Tenderloin

The Tenderloin & Mushroom Layers

Start by preheating a heavy skillet over moderately high heat. Add a bit of olive oil, toss in your mushrooms, and then let them cook until they’re nicely browned and any excess water has evaporated (usually around 8-10 minutes).

Filleting the tenderloin so that it will lay flat, and then adding the stuffing to it.

Follow it up by adding the spinach and cooking until it wilts and softens (approximately 5 minutes). Once done, take the veggie mixture off the heat.

Now, let’s tackle the beef tenderloin. Carefully butterfly it open, and then give it a good pounding until it’s an even thickness of about ½ inch. Spread your cooled sautéed mushrooms and spinach over the beef and then make a compact roll.

Secure the pinwheel roll with some butcher twine and then go ahead and set it aside.

The Beef Tenderloin is butterflied and then filled with a layer of spinach and mushrooms.

Making Al Trapo

Time to bring in the clean, unbleached white dish towel. Soak it in a bowl or baking sheet filled with your favorite red wine for about 5 minutes, before squeezing out any extra liquid.

Red wine is poured over the cotton dish towel to add moisture and flavor to the meat while cooking over the coals.

Then, lay the towel flat, and sprinkle 2 cups of kosher salt in the center. Add the Bourbon Prime Rub on top of the salt. Now, transfer beef to this flavorful bed and season it with the rest of the rub. 

Pat salt mixture on all sides of the meat. Cover the top of the tenderloin entirely with the remaining salt. Roll up the towel to wrap the salt-covered steak, securing it with more butcher twine.

The meat log is seasoned with my bourbon spice rub and salted.

Grilling Time for the Stuffed Lomo Al Trapo

The first step in the cooking process is to fire up your charcoal until the hot coals are blazing white. Brush off any loose ash and nestle your rolled-up piece of meat over the coals, cooking it for around 20 minutes on each side. Flip it halfway through. 

The Lomo Al Trapo is placed directly on white hot coals to cook.

Once done, and the internal temperature is 125 degrees F (read with an instant-read thermometer) take it off, and let the beef rest for a good 10-15 minutes.

After resting, unwrap the beef log, discard the towel and all the excess salt, and throw it back on the grill for a touch of crust before serving.

Now transfer the charred log to your cutting board.

Crafting the Grilled Veggie Salsa

While your coals work the magic on the tenderloin, toss your bell pepper and onion directly onto the coals for 8-10 minutes. Once they’re gloriously charred and softened, take them off and let them cool for 5 minutes.

The salsa is prepared with the freshest ingredients.

Peel off the charred skin from the onion and bell pepper, give them a good chop, and toss them into a large mixing bowl with all the other salsa ingredients. Mix it up and set it aside.

Slicing and Serving

Now for the moment of truth! Finally, slice the Lomo Al Trapo into thick slices with your sharp knife, and top with the Charred Salsa Vinaigrette. Enjoy every juicy and multi-layered, multi-textured bite!

The final result is a Lomo Al Trapo that is sliced on the cutting board.

What to Serve with Lomo al Trapo

Lomo Al Trapo pairs well with a variety of side dishes that complement its rich and savory flavors. Crispy and seasoned roasted potatoes or potato wedges would make a satisfying and hearty side dish.

In cooler months, a refreshing avocado salad with tomatoes, red onions, and cilantro would be the perfect complement to the charred tenderloin meat. 

Which red wines go best with beef tenderloin?

These red wines work for soaking the dish towel and for pairing with the meat when it is served on your table.

Malbec – A medium to full-bodied red wine with flavors of dark fruit, plums, and hints of spice. It’s always a good match for the smoky and charred notes from cooking over the fire.

Cabernet Sauvignon – This classic red wine is known for its bold black currant, cherry, and sometimes green bell pepper flavors. It always pairs well with rich and flavorful beef dishes.

Syrah/Shiraz – These two bold and spicy wines are a good match for all your grilled and smoked meats.

Leftovers & Reheating

As long as the meat is at room temperature, cover tightly in plastic wrap and keep it in an airtight container for 3-5 days in the refrigerator. 

When it comes time to reheat any leftover beef tenderloin, wrap the beef slices in aluminum foil to retain moisture. Place the foil packet in a preheated 275-degree F grill for about 15-20 minutes.

What type of salt is best for the salt crust?

Coarse kosher salt or sea salt works best for a salt crust. Avoid using table salt, as it may make the crust too salty.

Can I prepare the salt-crusted beef tenderloin in advance?

Yes, you can coat the beef with the salt crust a few hours before cooking and refrigerate. This allows the salt to penetrate the meat and enhances the flavor. Just make sure to bring it to room temperature before roasting over the grill.

Can I use this Al Trapo method for other cuts of meat?

While the salt crust technique is commonly used for the beef tenderloin cut of meat, you can experiment with other cuts like ribeye or sirloin, adjusting cooking times accordingly.
