Peruvian Lomo Saltado Recipe

The first time I made lomo saltado, I understood why the dish is so popular in Peru: it manages to be both a quick stir-fry and a proper plate of steak and potatoes. Thinly sliced sirloin is seared until browned, then tossed with red onion, tomatoes, garlic, ají amarillo paste, soy sauce, and red wine vinegar. That combination gives the dish its unmistakable character—savory and gently spicy, with a sharp, bright edge from the vinegar and a little sweetness from the tomatoes and onion. It is served over rice with crisp French fries, so every bite has something juicy, salty, tender, and crunchy in it. The technique matters more than the ingredient list suggests. The steak needs a very hot pan and enough space to brown rather than steam, while the vegetables should stay recognizable instead of collapsing into a sauce. I cook the sirloin in batches if necessary, remove it while it is still slightly underdone, and then quickly stir-fry the onion and garlic before adding the tomatoes. The ají amarillo paste brings a fruity chile flavor as much as heat; mixed with soy sauce and red wine vinegar, it creates a glossy, punchy pan sauce that clings to the steak without making it soggy. My most useful practical tip is to have everything sliced and measured before turning on the stove. Once the pan is hot, the cooking moves quickly, especially during the 15-minute cook time. Cut the sirloin across the grain into thin strips, and pat it dry so it sears properly. I also add the tomatoes near the end and toss them only until their edges soften. If they cook too long, they release enough water to cool the pan and dilute the sauce. For the best texture, keep the fries separate until serving rather than stirring them into the pan. This makes a lively 35-minute lunch for four, particularly when you want something more substantial than a standard stir-fry but do not want to spend the afternoon cooking. Serve the lomo saltado over steamed white rice, with the fries piled alongside or tucked underneath at the last minute. A simple green salad, sliced avocado, or a few pickled onions balances the rich steak and salty sauce. If you can find fresh ají amarillo, a few thin slices on top are a welcome finish, but the paste provides plenty of the pepper’s distinctive flavor.
