Step-by-Step Instructions

Prepare the Beef

Slice the beef into thin strips about ½ inch thick. Pat dry with paper towels. Removing moisture helps achieve a better sear when cooking Peruvian Lomo Saltado.

Season lightly with salt and black pepper.

Cook the Fries

Prepare French fries according to package instructions or fry fresh potatoes until golden brown and crispy.

Set aside on paper towels while preparing the rest of the Peruvian Lomo Saltado.

Heat the Pan

Place a wok or large skillet over very high heat. Add vegetable oil and allow it to heat until shimmering.

High heat is essential for authentic Peruvian Lomo Saltado flavor.

Sear the Beef

Add the beef strips in a single layer. Cook for about 1 minute without stirring so a golden brown crust forms.

Stir-fry quickly for another minute until the beef is browned but still tender.

Remove beef and set aside.

Cook the Aromatics

Add olive oil to the same wok.

Add minced garlic and sliced ají amarillo. Stir for about 30 seconds until aromatic.

Stir-Fry the Vegetables

Add sliced red onions and cook for about 1 minute.

They should soften slightly while still maintaining crisp texture.

Add tomato wedges and stir for another 30 seconds.

Add the Sauce

Return the cooked beef to the pan.

Pour in soy sauce, vinegar, and oyster sauce.

Toss everything quickly over high heat.

The sauce should sizzle immediately and coat the beef and vegetables.

Combine with Fries

Add the crispy French fries directly into the wok.

Toss gently so the fries absorb some of the flavorful sauce without becoming soggy.

Finish the Dish

Turn off the heat.

Sprinkle chopped cilantro on top.

Your authentic Peruvian Lomo Saltado is ready to serve.

Chef SOFIA Pro Tips

Use extremely high heat
Professional kitchens cook Peruvian Lomo Saltado over intense flame. Replicate this at home by preheating the pan well.

Do not overcrowd the pan
Cook the beef in batches if necessary. Overcrowding lowers the temperature and prevents proper browning.

Cut beef against the grain
This keeps the meat tender in Peruvian Lomo Saltado.

Add fries last
This keeps fries crispy while allowing them to absorb flavor.

Use fresh tomatoes
Fresh tomatoes create a light sauce instead of a heavy gravy.

Serve immediately
Peruvian Lomo Saltado tastes best when served hot straight from the wok.

Common Mistakes to Avoid

Cooking beef too long

Skipping vinegar
Vinegar balances the richness of the soy sauce.

Using thick beef slices
