Discover the Magic of Beef Stir-Fry Delight
There’s something magical about a dish that brings people together. I remember the first time I tried Lomo Saltado, or as I like to call it, Beef Stir-Fry Delight, at a Peruvian restaurant in Miami. The mix of tender beef, juicy tomatoes, and crispy fries was an explosion of flavors I couldn’t get enough of. When I decided to recreate it at home, I realized just how simple and rewarding this recipe is. It’s perfect for busy weeknights or when you want to impress your friends with something unique yet comforting.
A Taste of Peru: The Story Behind Beef Stir-Fry Delight
This dish hails from Peru, where it’s a beloved staple of criollo cuisine. Lomo Saltado is a fusion dish born out of the blending of Chinese and Peruvian culinary traditions. Back in the 19th century, Chinese immigrants brought wok cooking techniques to Peru, and locals adapted them using local ingredients. The result? A vibrant stir-fry that combines marinated beef, fresh veggies, and tangy sauces served alongside rice and fries. I love how it bridges cultures while still feeling like home-cooked comfort food.

Ingredients You’ll Need
- 450 g sirloin steak, thinly sliced against the grain
- 3-4 tablespoons vegetable oil, divided
- 1 small red onion, thinly sliced
- 2 small tomatoes or plum tomatoes, quartered
- 4 green onions, trimmed and cut into 5 cm pieces
- 3 garlic cloves, peeled and minced
- 1-inch piece of ginger, peeled and finely grated (optional)
- 1 heaping tablespoon yellow chili paste (aji amarillo) or sliced fresh aji amarillo
- 1 tablespoon chopped fresh cilantro, plus more for garnish
- Steamed white rice, for serving
- Fries (homemade or store-bought), for serving
For the Marinade:
- 2 tablespoons soy sauce
- 1/8 teaspoon ground cumin (adjust to taste)
- 1/4 teaspoon dried oregano
- 1 tablespoon apple cider vinegar, white vinegar, or sherry vinegar
For the Stir-Fry Sauce:
- 4 tablespoons soy sauce
- 1 tablespoon apple cider vinegar or white vinegar
- 1 teaspoon cornstarch (optional, for thickening)
Substitution Options
No sirloin steak? No problem! You can swap it for flank steak or even chicken breast if you prefer. If you can’t find aji amarillo paste, a mild red chili paste works well too. For those avoiding carbs, cauliflower rice makes a fantastic low-carb alternative to regular rice. And if homemade fries feel like too much effort, good-quality frozen fries are totally acceptable.
Step 1: Marinate the Steak
Start by slicing the steak thinly against the grain—it’s key to keeping it tender. In a bowl, toss the slices with soy sauce, cumin, oregano, and vinegar. Let it sit while you prep the other ingredients. This short marinade time packs a punch of flavor without requiring hours of waiting. Pro tip: Use a sharp knife for clean cuts and better texture.
Step 2: Prepare the Sauce
In a small bowl, whisk together soy sauce, vinegar, and cornstarch if you’re using it. This sauce will thicken slightly as it cooks, coating every bite beautifully. Keep it nearby because once the stir-fry gets going, things move fast!
Step 3: Sear the Steak
Heat a tablespoon of oil in a large skillet or wok over medium-high heat. Add the steak in batches to avoid overcrowding—this ensures each piece gets a nice sear instead of steaming. Cook until golden brown, about 5-6 minutes total. Remove and set aside. The aroma of sizzling beef is enough to make anyone hungry!
Step 4: Soften the Red Onions
In the same pan, add another tablespoon of oil and sauté the red onions until they soften, around 2-5 minutes. They should still hold their shape but become fragrant and slightly translucent. Once done, remove and reserve them with the beef.
Step 5: Stir-Fry the Vegetables
Add another tablespoon of oil to the pan, then throw in the green onions, tomatoes, garlic, and aji amarillo paste. Cook for 2-5 minutes, letting the tomatoes release some juice but not collapse completely. The colors here are stunning—the bright reds and greens pop against the rich browns of the cooked meat.
Step 6: Add the Sauce
Pour the reserved sauce into the pan and let it simmer for about a minute. Watch as it bubbles and thickens slightly, creating a glossy coating for the vegetables. This step ties all the flavors together.
Step 7: Assemble the Dish
Return the beef and onions to the pan, along with any juices that have accumulated. Sprinkle with chopped cilantro and give everything a gentle toss. The cilantro adds a fresh, herby note that balances the richness of the dish.
Step 8: Serve and Enjoy
Serve your Beef Stir-Fry Delight hot with steamed rice and crispy fries. For a traditional twist, mix the fries right into the stir-fry before serving. Garnish with extra cilantro for a pop of color.
Chef’s Tip
To take this dish to the next level, use freshly ground cumin. Its earthy warmth really shines through and elevates the entire flavor profile.

Extra Info
Did you know that Lomo Saltado is often considered one of Peru’s national dishes? Its popularity stems from its accessibility and deliciousness, making it a favorite among locals and tourists alike.
Necessary Equipment
You’ll need a large skillet or wok, a sharp chef’s knife, cutting board, mixing bowls, and measuring spoons. A spatula or wooden spoon is handy for stirring everything together.
Storage Tips
If you have leftovers, store them in an airtight container in the fridge for up to three days. Reheat gently in a skillet to maintain the texture of the beef and veggies. Avoid microwaving if possible, as it can make the fries soggy.
For longer storage, freeze portions in freezer-safe bags. Thaw overnight in the fridge before reheating. Note that the fries may lose some crispiness, but the flavors remain incredible.
Keep the rice separate from the stir-fry when storing to prevent it from absorbing excess moisture, which could make it mushy.
Tips and Advice
Don’t skip the resting period for the marinade—even five minutes makes a difference. Also, slice the beef as thinly as possible for maximum tenderness. Lastly, taste as you go; adjust seasonings to suit your preferences.
Presentation Ideas
- Serve the dish family-style on a large platter surrounded by lemon wedges.
- Garnish with extra cilantro and thinly sliced red onions for a colorful finish.
- Arrange the fries artfully around the edges of the plate for a rustic look.
Healthier Alternatives
Here are six variations to lighten up your Beef Stir-Fry Delight:
- Lean Protein Swap: Use lean ground turkey instead of beef for fewer calories.
- Veggie Boost: Add bell peppers or zucchini for extra nutrients.
- Low-Sodium Option: Opt for reduced-sodium soy sauce to cut back on salt.
- Baked Fries: Make oven-baked sweet potato fries for a healthier side.
- Gluten-Free Version: Substitute tamari for soy sauce to make it gluten-free.
- Keto-Friendly Twist: Skip the rice and serve the stir-fry over cauliflower rice.
Common Mistakes to Avoid
Mistake 1: Overloading the Pan
Cooking too much beef or veggies at once lowers the pan temperature, leading to steaming instead of searing. Cook in batches to ensure proper browning. Pro tip: Preheat your pan before adding oil for optimal heat retention.
Mistake 2: Skipping the Resting Time
Not letting the beef rest after marinating means less flavor penetration. Even a few minutes allows the spices to work their magic.
Mistake 3: Overcooking the Tomatoes
Tomatoes should soften but retain their structure. Cook them just until they release some juice; otherwise, they turn mushy and lose their vibrant appeal.
Mistake 4: Using Old Spices
Spices lose potency over time. Check the expiration dates on your cumin and oregano for the best results.
Mistake 5: Neglecting Fresh Herbs
Fresh cilantro is non-negotiable here. Dried herbs won’t provide the same brightness and freshness.
