Its unique combination of textures and tastes makes it a beloved comfort food both in Peru and around the world. This guide will walk you through each step, ensuring you create an authentic and delicious Lomo Saltado at home.

## What is Lomo Saltado?

Lomo Saltado translates to “stir-fried loin.” It’s a dish that reflects Peru’s rich cultural heritage and its embrace of diverse culinary influences. The arrival of Chinese immigrants in the 19th century significantly impacted Peruvian cuisine, leading to the development of dishes like Lomo Saltado, which incorporate stir-frying techniques and Asian-inspired sauces. The dish typically includes beef tenderloin (lomo), onions, bell peppers, tomatoes, and French fries, all seasoned with soy sauce, vinegar, garlic, and Peruvian chili peppers (aji amarillo). The key is to cook everything quickly over high heat, ensuring the beef remains tender and the vegetables retain their crispness.

## The Key to Authentic Lomo Saltado

Several factors contribute to the authenticity and deliciousness of Lomo Saltado:

* **High Heat:** Essential for achieving the characteristic slightly charred edges on the beef and vegetables while maintaining their texture.
* **Quality Beef:** Use a tender cut of beef like sirloin or tenderloin for optimal results. Cut it into thin strips against the grain.
* **Fresh Ingredients:** Fresh vegetables and aromatics are crucial for vibrant flavors.
* **Proper Sauce:** The sauce, a blend of soy sauce, vinegar, and spices, provides the dish’s signature savory and tangy profile. Using aji amarillo paste or chili adds a crucial Peruvian flavor dimension.
* **Crispy Fries:** The fries should be perfectly golden and crispy to provide a textural contrast to the tender beef and vegetables. Some recipes call for mixing the fries in at the end, so they soften slightly and absorb the sauce. Others serve them on the side to keep them crisp.
* **Wok (Optional but Recommended):** A wok’s shape and ability to distribute heat evenly make it ideal for stir-frying. However, a large skillet can also be used.

## Ingredients

* **Beef:** 1 pound beef tenderloin or sirloin, cut into thin strips (approximately 2 inches long and 1/2 inch thick).
* **Potatoes:** 2 large Russet potatoes, peeled and cut into thick-cut fries.
* **Onion:** 1 red onion, sliced into wedges.
* **Bell Pepper:** 1 red bell pepper, sliced into strips.
* **Tomato:** 2 ripe tomatoes, cored and cut into wedges.
* **Aji Amarillo Paste:** 1-2 tablespoons (adjust to taste for heat level). If you can’t find Aji Amarillo Paste, you can substitute with a small amount of another chili paste or even a pinch of cayenne pepper, though it won’t provide the same authentic flavor.
* **Garlic:** 2 cloves, minced.
* **Soy Sauce:** 4 tablespoons.
* **Red Wine Vinegar:** 2 tablespoons (or white vinegar).
* **Vegetable Oil:** For frying and stir-frying.
* **Cilantro:** 1/4 cup, chopped (for garnish).
* **Salt and Pepper:** To taste.
* **Cooked White Rice:** For serving (optional).

## Equipment

* Large skillet or wok
* Large pot or deep fryer for frying potatoes
* Cutting board
* Sharp knife
* Mixing bowls
* Slotted spoon

## Step-by-Step Instructions

**Step 1: Prepare the Fries**

1. **Cut the Potatoes:** Peel the potatoes and cut them into thick-cut fries. Aim for a consistent size to ensure even cooking.
2. **Soak the Fries (Optional):** Place the cut fries in a bowl of cold water for at least 30 minutes. This helps remove excess starch, resulting in crispier fries. Drain well and pat dry before frying.
3. **First Fry:** Heat about 2 inches of vegetable oil in a large pot or deep fryer to 325°F (160°C). Fry the potatoes in batches for about 5-7 minutes, until they are slightly softened but not yet golden brown. Remove with a slotted spoon and place on a wire rack to drain.
4. **Second Fry:** Increase the oil temperature to 375°F (190°C). Fry the potatoes again for 2-3 minutes, until they are golden brown and crispy. Remove with a slotted spoon and place on a wire rack lined with paper towels to drain. Season with salt immediately.

**Step 2: Prepare the Beef and Vegetables**

1. **Prepare the Beef:** Pat the beef strips dry with paper towels. This helps them sear properly. Season with salt and pepper.
2. **Prepare the Vegetables:** Slice the red onion into wedges, the bell pepper into strips, and the tomatoes into wedges. Mince the garlic.

**Step 3: Stir-Fry the Beef**

1. **Heat the Wok/Skillet:** Heat 1-2 tablespoons of vegetable oil in a large skillet or wok over high heat until it’s smoking hot. The key is to have the pan very hot to get a good sear on the beef.
2. **Sear the Beef:** Add the beef strips to the hot wok/skillet in a single layer (work in batches if necessary to avoid overcrowding). Sear the beef for 1-2 minutes per side, until browned but still slightly pink inside. Remove the beef from the wok/skillet and set aside.

**Step 4: Stir-Fry the Vegetables**

1. **Sauté the Aromatics:** Add another tablespoon of vegetable oil to the wok/skillet. Add the minced garlic and sauté for about 30 seconds, until fragrant. Be careful not to burn the garlic.
2. **Add the Onions and Bell Peppers:** Add the sliced red onion and bell pepper strips to the wok/skillet and stir-fry for 2-3 minutes, until slightly softened but still crisp-tender.
3. **Add the Tomatoes:** Add the tomato wedges to the wok/skillet and stir-fry for another minute, until they are slightly softened but still retain their shape.

**Step 5: Create the Sauce**

1. **Add the Aji Amarillo Paste:** Stir in the Aji Amarillo paste (or chili paste substitute) and cook for 30 seconds, stirring constantly.
2. **Deglaze with Vinegar:** Pour in the red wine vinegar and stir to deglaze the pan, scraping up any browned bits from the bottom. This adds flavor to the sauce.
3. **Add the Soy Sauce:** Add the soy sauce and stir to combine all the ingredients.

**Step 6: Combine and Finish**

1. **Return the Beef:** Return the seared beef to the wok/skillet with the vegetables and sauce. Toss everything together to coat the beef evenly in the sauce.
2. **Add the Fries:** Add the crispy fries to the wok/skillet and toss gently to combine. Some people prefer to serve the fries on the side to keep them crispy, so consider your preference.
3. **Adjust Seasoning:** Taste and adjust seasoning with salt and pepper as needed.

**Step 7: Serve**

1. **Garnish:** Garnish with freshly chopped cilantro.
2. **Serve Immediately:** Serve Lomo Saltado immediately over cooked white rice (optional) or on its own. The dish is best enjoyed hot.

## Tips for the Perfect Lomo Saltado

* **Don’t Overcrowd the Pan:** Overcrowding the wok/skillet will lower the temperature and steam the ingredients instead of searing them. Work in batches if necessary.
* **Use High Heat:** High heat is crucial for achieving the characteristic charred edges and preventing the beef from becoming tough.
* **Pat the Beef Dry:** Patting the beef dry before searing ensures a good sear and prevents it from steaming.
* **Don’t Overcook the Beef:** Cook the beef quickly and to medium-rare or medium for the best tenderness.
* **Adjust the Sauce to Your Taste:** Adjust the amount of Aji Amarillo paste and soy sauce to your preference.
* **Fresh is Best:** Use fresh ingredients whenever possible for the best flavor.
* **Double Fry the Fries:** Double frying the fries ensures they are extra crispy.
* **Serve Immediately:** Lomo Saltado is best enjoyed immediately after cooking. If you let it sit, the fries will become soggy.
* **Experiment with Vegetables:** While traditional Lomo Saltado uses onions, bell peppers, and tomatoes, you can experiment with other vegetables like mushrooms, snow peas, or broccoli.
* **Consider Marinating the Beef:** Marinating the beef for 30 minutes in a mixture of soy sauce, garlic, and ginger can enhance its flavor and tenderness.

## Variations on Lomo Saltado

While the classic recipe is a favorite, there are several variations you can try:

* **Chicken Lomo Saltado (Pollo Saltado):** Substitute the beef with chicken breast or thighs.
* **Seafood Lomo Saltado (Mariscos Saltado):** Use shrimp, squid, or other seafood instead of beef.
* **Vegetarian Lomo Saltado:** Use mushrooms, tofu, or a combination of vegetables instead of beef. You can also add vegetarian oyster sauce for a more authentic flavor.
* **Lomo Saltado with Quinoa:** Serve the Lomo Saltado over quinoa instead of rice for a healthier option.
* **Spicy Lomo Saltado:** Add more Aji Amarillo paste or other chili peppers for a spicier kick.

## Serving Suggestions

Lomo Saltado is traditionally served with white rice, which helps soak up the delicious sauce. It can also be served with quinoa, potatoes, or even pasta. A side of fresh salad or a simple vegetable dish can complement the richness of the stir-fry. A cold Peruvian beer or a glass of dry white wine pairs well with this dish.

## Storage and Reheating

Lomo Saltado is best enjoyed fresh. However, leftovers can be stored in an airtight container in the refrigerator for up to 2-3 days. When reheating, the fries will likely become soft. You can reheat the Lomo Saltado in a skillet over medium heat, stirring occasionally, until heated through. For the fries, you can try to crisp them up in a hot oven or air fryer, but they won’t be as crispy as when freshly made.
