Ingredients

Instructions

  1. Step 1: Heat 2 tbsp vegetable oil in a large cast-iron or heavy skillet over high heat until shimmering. Add 12 oz thinly sliced sirloin steak and sear for 2 minutes without stirring, then toss and cook another 1 minute until nicely browned but still juicy. Remove beef and set aside.
  2. Step 2: In the same skillet, add 1 tbsp vegetable oil and 1 large sliced red onion. Stir-fry over medium-high heat for 2 minutes until edges begin to char and soften.
  3. Step 3: Add 2 medium tomato wedges and 1 tbsp aji amarillo paste to the onions. Stir and cook for 1 minute until tomatoes soften but retain shape.
  4. Step 4: Return the beef to the pan, then pour in 3 tbsp soy sauce and 1 tbsp red wine vinegar. Stir everything together and cook for 1 minute until the sauce slightly thickens and coats the beef and vegetables.
  5. Step 5: Gently fold in 2 cups hot French fries and 2 tbsp chopped fresh cilantro. Toss carefully to combine and heat through for 1 minute. Season with salt and black pepper to taste.
  6. Step 6: Serve immediately with 2 cups cooked white rice on the side for a classic Peruvian meal.
