Lomo Saltado (The Wok-Fire Express)
Almuerzo Turned Supper (The Heavy Hitters)
If you close your eyes and breathe in the violent sizzle of soy sauce, vinegar, and searing beef hitting a screaming-hot pan, you're instantly transported to the bustling chifas of Lima—or maybe your parents' kitchen in Ohio on a Tuesday night. Born from 19th-century Chinese immigrants who introduced the wok to Peru, this dish marries Cantonese stir-fry technique with Andean potatoes and the bright, fruity heat of ají amarillo. To make this work without losing your mind on a weeknight, we skip the traditional double-fry and deploy high-quality frozen French fries, letting you focus entirely on ripping high heat and achieving that glorious, smoky sear on the beef.
Before you start
Bake the French fries until exceptionally crispy.
Get your oven or air-fryer going according to the package directions while you prep the rest of the ingredients.
Mix the master sauce.
In a small jar, vigorously whisk the soy sauce, red wine vinegar, oyster sauce, ají amarillo paste, and beef broth, then set it right next to the stove so you aren't scrambling later.
Quickly marinate the beef.
Toss the sliced beef with the minced garlic, grated ginger, and exactly 1 tbsp of your master sauce, letting it sit for 5 to 10 minutes while you prep the vegetables.
Ingredients
- top sirloin or beef tenderloin1 lb
- frozen French fries1 lb
- cooked white rice2 cup
- neutral oil3 tbsp
- red onion1 large
- plum tomatoes2 large
- scallions2 med
- fresh cilantro1/4 cup

- red wine vinegar3 tbsp
- oyster sauce1 tbsp
- ají amarillo paste1 tbsp
- garlic3 med cloves
- fresh ginger1 tsp
- beef broth1/4 cup
Method
- 01
Sear the beef hard and fast in a smoking-hot pan.
Turn on your kitchen exhaust fan. Heat a wok or a heavy 12-inch cast-iron skillet over maximum heat until smoking, add 1 1/2 tbsp of the neutral oil, and lay the beef down in a single layer. Don't touch it for 60 seconds to build an aggressive crust, toss for another 60 seconds, then immediately remove the beef and its juices to a clean plate.
- 02
Blister the vegetables without losing their crunch.
Add the remaining 1 1/2 tbsp of oil to the same smoking pan, toss in the red onion wedges, and stir-fry for exactly 1 minute before adding the tomatoes for a final 30 seconds.
- 03
Deglaze and marry the flavors.
Pour the master sauce mixture into the screaming hot pan so it instantly hisses and reduces, then dump the beef, resting juices, scallions, and half the cilantro back in. Toss violently for 30 to 45 seconds until the sauce thickens into a glossy glaze, then immediately kill the heat.
- 04
Plate the meat alongside the carbs.
Serve a bed of ultra-crispy fries next to a mound of white rice, spooning the heavy, savory juices of the lomo directly over the potatoes and garnishing with the remaining cilantro.
Notes
Respect the batch size.
If your pan is small, sear the meat in two batches. Overcrowding drops the temperature and steams the beef, robbing you of that essential smoky crust.
Don't skip the oyster sauce.
It bridges the gap between the savory beef and the acidic vinegar, providing the deep, umami-rich backbone that defines true Chinese-Peruvian cooking.
