The beef is critical here. Sirloin provides the right balance of tenderness and flavor for quick cooking. Look for well-marbled cuts at Whole Foods or your local butcher. For the potatoes, russets yield the crispiest fries—avoid waxy varieties. Aji amarillo paste (available at Latin markets or online) is traditional, but don’t stress if you can’t find it.

No sirloin? Flank steak or ribeye work well too—just slice thinly against the grain. Skip the aji amarillo? Substitute with a pinch of cayenne for heat, though the flavor profile differs. Fresh cilantro is ideal, but flat-leaf parsley can stand in if needed. The vinegar matters—red wine vinegar adds the right tang, but apple cider works in a pinch.

Fry the potatoes first and keep warm in the oven (200°F). The dish comes together quickly, so have all ingredients prepped and within reach. Leftovers keep 2-3 days in the fridge, though best served fresh. The fries lose crispness but the flavors deepen beautifully.

Step-by-Step Instructions for Wok-Tossed Beef With Tomato and Fries

Master the technique for this Peruvian classic with crispy fries and perfectly seared beef strips.

Step 1: Fry the Russet Potatoes to Golden Perfection

Heat ½ cup of the vegetable oil in a deep skillet over medium-high heat to 350°F. Carefully add the peeled and cut russet potatoes in batches to avoid overcrowding. Fry for 4-5 minutes until golden brown and crisp, turning occasionally for even browning.

Transfer the fried potatoes to a paper towel-lined plate to drain excess oil. Season immediately with ½ tsp of the salt while still hot. The residual heat ensures the seasoning adheres properly. Set aside to maintain their crispness while you prepare the remaining components.

Step 2: Marinate and Sear the Beef Sirloin

In a bowl, combine the thinly sliced beef sirloin with 2 tbsp of the soy sauce, 1 tbsp of the vegetable oil, 1 tsp ground cumin, and ½ tsp black pepper. Toss to coat evenly and let marinate for 10 minutes at room temperature.

Heat 2 tbsp of the remaining vegetable oil in a wok or large skillet over high heat until shimmering. Add the marinated beef sirloin in a single layer, working in batches if necessary. Sear for 2-3 minutes until deeply browned but still slightly pink inside. Remove from the wok and set aside.

Step 3: Sauté the Aromatics and Roma Tomatoes

In the same wok, reduce heat to medium. Add the thinly sliced red onion and cook for 2 minutes until it begins to soften. Stir in the minced garlic cloves and 1 tbsp aji amarillo paste, cooking for 30 seconds until fragrant.

Add the Roma tomatoes cut into eighths and the remaining 1 tbsp soy sauce. Cook for 3-4 minutes, stirring occasionally, until the tomatoes begin to break down and release their juices. Pour in the 2 tbsp red wine vinegar to balance the acidity and deglaze the pan.

Step 4: Combine All Elements and Finish

Return the seared beef sirloin and its accumulated juices to the wok. Add the crispy russet potatoes and toss everything together over medium-high heat for 1-2 minutes to combine the flavors. The beef should be fully cooked through and the potatoes should remain crisp.

Taste and adjust seasoning with the remaining ½ tsp salt if needed. Remove from heat and stir in the chopped fresh cilantro. Serve immediately in the wok or transfer to a large platter, ensuring each serving gets an even mix of beef, tomatoes, and crispy fries.

Storing and Reheating Leftovers

Refrigerator Storage

Let your dish cool for no more than 2 hours before transferring to airtight containers. I use glass containers with snap-tight lids for best results. Store at 40°F or below for up to 3 days. The flavors actually meld beautifully overnight. ❄️

Freezer Storage

This freezes well for up to 2 months without significant quality loss. Use quart-size freezer bags for space efficiency. Leave 1 inch headspace for expansion and squeeze out excess air to prevent freezer burn. Label with the date for easy tracking.

Stovetop Reheating

My preferred method for maintaining texture. Heat in a skillet over medium-low heat with 2 tbsp water or beef broth to prevent drying. Cover and heat for 5-7 minutes, stirring occasionally. The fries will soften but the flavors stay vibrant.

Microwave Reheating

For quick meals, microwave individual portions covered with a damp paper towel. Use 70% power for 2-3 minutes, then stir. Continue in 30-second intervals until reaching 165°F. Add a splash of water if needed. 🔥

Honestly, the stovetop method tastes better but the microwave works in a pinch.
