Peruvian Steak Stir-Fry with Onions and Tomatoes (Lomo Saltado)
Peru’s lomo saltado, a quick stir-fry of soy-marinated beef, tomatoes and onions, is part of chifa cuisine—Asian-influenced dishes created by indentured Chinese workers in the late 19th century. For our take, we developed deeper flavor by mixing ground cumin into the soy sauce marinade. Tenderloin is often used here, but we preferred sirloin tips (also called flap meat) for their meatier flavor as well as lower price. And we seared the meat instead of stir-frying. Readily available jalapeño peppers made a good substitute for the traditional yellow ají peppers. If you prefer little to no spiciness, halve and seed the jalapeño before slicing it into half rings. Classic lomo saltado is frequently served over french fries; your favorite, frozen or otherwise, would be a good choice here. Steamed rice is an equally good accompaniment.

Tip
Don't cook the beef without patting it dry. Marinating in soy sauce adds flavor, but also moisture. Drying the beef helps ensure that the slices sear nicely, rather than steam. Also, cook in two batches; crowding the pan inhibits browning.

Lomo Saltado
There is something about serving this stir fry with French fries that I find so festive and fun. This is what one does if they're an expert at enjoying life, right?
The soy sauce, vinegar, and cumin might look a little pedestrian as the main seasonings, but this is a case of the parts becoming a perfect whole.

Outstanding!
The only thing I did differently was added more garlic. Otherwise, I followed the recipe exactly. It was super easy, absolutely delicious, and comforting on a cold night. Adding to my repertoire! CK and the Milk Street team did it again!

Loved this, simple yet extremely flavorful. I basically followed the recipe but marinated the meat for a couple hours in the fridge ( used sirloin which can be tougher than other cuts) and added an extra 1/2 cup of tomatoes based on other reviews . Had a large jalapeño and used a mandolin to make thin slices. Definitely keeping in my recipe rotation.
Made this last night using flank steak, because that's what is easiest to find. It was delicious; I should left the seeds and ribs in the jalapeno as it was milder than I would have liked, but I added red pepper flakes at the table to compensate. Served with white rice and steamed green beans.
Hi Maureen -
As mentioned in the headnote of the recipe, sirloin tips are sometimes sold as flap meat, however it can also be sometimes be called bavette steak. If you can't find flap meat you can also try this with skirt, flank, or flatiron steak as some have mentioned in previous comments. These cuts are slightly more lean than flap meat, but should still work fine in the recipe.
Best,

Does anybody think this recipe could be adapted for use with lamb? If so would any adjustments to the other ingredients be needed?
