Sauteed Beef Tenderloin: A Culinary Journey to Peru

The first time I tasted Lomo Saltado, sauteed beef tenderloin, was in a tiny, bustling comedor in Lima. The air was thick with the aroma of sizzling beef, spices, and the comforting scent of freshly fried potatoes. The chef, a woman with hands that moved with astonishing speed and precision, plated a steaming portion for me. The combination of tender beef, perfectly cooked onions and tomatoes, and crispy fries, all bathed in a flavorful sauce, was a revelation. It was more than just a meal; it was a taste of Peruvian soul.

Ingredients

• 2 1/4 lbs beef tenderloin, sliced into thin strips
• 3 red onions, peeled and cut into eight pieces
• 2 garlic cloves, chopped
• 2 1/4 lbs all-purpose potatoes, peeled and cut for French fries, or 2 1/4 lbs frozen French fries
• 4 fresh yellow peppers, sliced into thin strips (optional)
• 4 tomatoes, cut into eighths
• 2 tablespoons chopped parsley or 2 tablespoons cilantro
• 1 tablespoon white vinegar
• 2 tablespoons soy sauce
• 1 1/4 cups oil
• Pepper to taste
• Red wine (to flame the meat) (optional) or Pisco (to flame the meat) (optional)

Equipment Needed

• Large skillet
• Large nonstick skillet
• Paper towels
• Serving dish

Instructions

1. Heat ½ cup of oil in a large skillet over high heat.
2. Add the beef strips to the skillet. Make sure the beef has already been seasoned with pepper and garlic. Quickly sauté the beef until it is seared and browned on all sides.
3. Optional: At this point, you can add a splash of red wine or Pisco to the pan to flame the meat. Be extremely careful when working with open flames. Ensure proper ventilation and keep flammable materials away from the cooking area. This adds a unique depth of flavor.
4. Remove the pan from the heat and transfer the beef to a plate. Cover the plate to keep the beef warm.
5. Return the pan to medium-high heat and add 1 ½ tablespoons of oil.
6. Add the onions and sauté until the edges are seared and they begin to soften, approximately 2 minutes.
7. Add the yellow chili (if using), tomatoes, parsley or cilantro, salt, pepper, soy sauce, and white vinegar to the pan.
8. Sauté until the tomatoes have softened, approximately 2 minutes.
9. Add the beef back to the pan and toss gently to combine it with the vegetables and sauce.
10. Heat ¾ cups of oil in a large nonstick skillet over medium heat.
11. Add the potatoes (either fresh-cut or frozen French fries) and sauté until they are browned and tender, approximately 15 minutes. Ensure even cooking by tossing them occasionally.
12. Drain the French fries on paper towels to remove excess oil.
13. To serve, unmold cooked rice (not included in the ingredient list, but traditionally served alongside) in the center of a serving dish. Place the beef mixture and French fries on each side of the rice. Sprinkle with finely chopped parsley or cilantro.
14. Serve immediately and enjoy!

Expert Tips & Tricks

• Achieve Maximum Sear: To get a beautiful sear on your beef, ensure the pan is extremely hot before adding the beef. Work in batches if necessary to avoid overcrowding the pan, which will lower the temperature and prevent proper browning.
• Flavor Boost: Marinate the beef in soy sauce, garlic, and pepper for at least 30 minutes (or even overnight) before cooking to enhance the flavor.
• Onion Perfection: Don’t overcook the onions. You want them to be slightly softened but still retain some bite. This contrast in textures is essential for the dish.
• Fresh vs. Frozen Fries: While fresh-cut fries offer superior flavor and texture, using frozen fries is a great shortcut for busy weeknights. Just make sure to choose a high-quality brand.
• Flame with Caution: If you choose to flame the meat, ensure you have all the ingredients prepped and ready to go. Pour the alcohol into the pan away from the heat source to avoid accidental ignition of the bottle.

Serving & Storage Suggestions

Serve this delicious sauteed beef tenderloin immediately while it’s hot and the fries are crispy. The dish is traditionally served with steamed white rice to soak up the flavorful sauce.

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, gently warm the beef and vegetable mixture in a skillet over medium heat. Reheat the French fries in a preheated oven or air fryer to restore their crispness. Avoid microwaving the fries, as they will become soggy.

It’s not recommended to freeze this dish, as the texture of the potatoes and the beef can deteriorate upon thawing.
