In this comprehensive guide, we'll walk you through the steps to cook Lomo Saltado on a grill, ensuring perfect results every time in 2026.

The History and Appeal of Lomo Saltado

Lomo Saltado is a testament to Peru's rich culinary history, blending indigenous and immigrant influences. The dish originated in the late 19th century when Chinese immigrants in Peru adapted their stir-fry techniques to local ingredients. The result is a fusion of flavors that has become a national treasure. Grilling Lomo Saltado adds a modern twist, infusing the dish with smoky notes that complement its tangy sauce and tender meat.

Essential Ingredients for Grilled Lomo Saltado

To cook Lomo Saltado on a grill, you'll need the following ingredients:

  • 500g sirloin steak, sliced into thin strips
  • 2 yellow onions, sliced
  • 3 ripe tomatoes, sliced
  • 3 cloves garlic, minced
  • 2 ají Amarillo peppers, seeded and finely chopped
  • 1/4 cup red wine vinegar
  • 1/4 cup soy sauce
  • 2 tablespoons olive oil
  • 1 teaspoon ground cumin
  • 1 teaspoon smoked paprika
  • Salt and pepper to taste
  • Fresh cilantro and green onions for garnish

Marinating the Steak

The key to tender and flavorful Lomo Saltado is a well-marinated steak. Follow these steps to prepare the marinade:

  1. In a bowl, combine the minced garlic, chopped ají Amarillo peppers, red wine vinegar, soy sauce, olive oil, cumin, smoked paprika, salt, and pepper.
  2. Add the sliced sirloin strips to the marinade, ensuring each piece is well coated.
  3. Cover the bowl and refrigerate for at least 2 hours, or ideally overnight, to allow the flavors to penetrate the meat.

Preparing the Vegetables

While the steak is marinating, prepare the vegetables:

Slice the onions into thin strips and set aside. Slice the tomatoes and also set aside. These will be grilled separately to add a smoky flavor to the dish.

Grilling Lomo Saltado

Now that your ingredients are ready, it's time to fire up the grill. Follow these steps for perfect results:

Step 1: Preheat the Grill

Preheat your grill to medium-high heat. This ensures that the steak gets a nice sear while retaining its juices.

Step 2: Grill the Steak

Remove the steak from the marinade and shake off any excess. Grill the steak strips for about 3-4 minutes on each side, depending on your desired level of doneness. For a medium-rare steak, aim for an internal temperature of 135°F (57°C).

Once grilled, transfer the steak to a plate and let it rest for a few minutes to allow the juices to redistribute.

Step 3: Grill the Onions and Tomatoes

While the steak is resting, grill the sliced onions and tomatoes. Place them on the grill for about 2-3 minutes on each side, until they develop grill marks and start to soften. Be careful not to overcook them, as they should retain some crunch.

Step 4: Assemble the Dish

In a large skillet or griddle, combine the grilled onions, tomatoes, and any remaining marinade. Cook for an additional 2-3 minutes to meld the flavors.

Add the grilled steak strips to the skillet and toss everything together. Cook for another 1-2 minutes to ensure all the ingredients are heated through.

Serving Lomo Saltado

Lomo Saltado is typically served with a side of steamed rice and French fries. The combination of the smoky steak, tangy sauce, and crispy fries makes for a satisfying meal. Garnish with fresh cilantro and green onions for added freshness and color.

To impress your guests in 2026, consider presenting the dish family-style, allowing everyone to help themselves to the grilled steak and vegetables. Pair it with a crisp white wine or a refreshing Peruvian beer for a complete dining experience.

Tips for Perfect Grilled Lomo Saltado

Achieving the perfect Lomo Saltado on the grill requires attention to detail. Here are some tips to help you succeed:

Choose the Right Cut of Meat

Sirloin steak is the traditional cut for Lomo Saltado, but you can also use flap or hanger steak for a more flavorful option. Whatever cut you choose, ensure it is sliced thinly against the grain for tenderness.

Marinate for Maximum Flavor

Marinating the steak for at least 2 hours, or preferably overnight, allows the flavors to penetrate deeply. If you're short on time, a quick marinade can still work, but the longer the better.

Maintain Grill Temperature

Consistent grill temperature is crucial for evenly cooked steak. Use a meat thermometer to monitor the internal temperature and avoid overcooking.

Keep Vegetables Crisp

Grill the onions and tomatoes just until they soften and develop grill marks. Overcooking can make them mushy, so keep a close eye on them.

Rest the Meat

Allowing the grilled steak to rest for a few minutes before slicing helps the juices redistribute, ensuring a juicy and flavorful dish.

Variations and Substitutions

While the classic Lomo Saltado recipe is delicious, you can experiment with variations and substitutions to make it your own. Here are a few ideas:

Spice It Up

For those who enjoy a bit of heat, add sliced jalapeño peppers or a dash of hot sauce to the marinade. This will give your Lomo Saltado an extra kick.

Add Vegetables

Incorporate other vegetables like bell peppers or zucchini into the dish. Simply slice them and grill along with the onions and tomatoes.

Use Different Proteins

While sirloin is traditional, you can also use chicken, pork, or even tofu for a vegetarian option. Adjust the marinating and grilling times accordingly.

Feel free to experiment with different herbs and spices to create a unique flavor profile that suits your taste.
