Equipment

  • Large skillet or wok
  • Chef's knife
  • Cutting board
  • Mixing bowl
  • Tongs

Ingredients

Beef and Marinade

  • 1 1/2 lb sirloin steak cut into thin strips
  • 1 tsp kosher salt divided
  • 1/2 tsp black pepper freshly ground
  • 2 tbsp soy sauce divided
  • 1 tbsp red wine vinegar or white vinegar

Stir-Fry

  • 2 tbsp vegetable oil divided
  • 1 large red onion cut into thick wedges
  • 2 medium tomatoes cut into wedges
  • 1 tbsp aji amarillo paste or mild yellow chile paste
  • 2 cloves garlic minced
  • 1/2 tsp ground cumin
  • 1/4 cup beef stock or water
  • 2 tbsp fresh cilantro chopped

To Serve

  • 4 cups cooked French fries kept hot and crisp
  • 2 cups cooked white rice

Instructions

Season and sear the beef:

  • Toss the beef with half of the salt, the black pepper, 1 tablespoon soy sauce, and the vinegar. Let it stand for 10 minutes.
  • Heat a large skillet or wok over high heat. Add 1 tablespoon oil and sear the beef in a single layer, working in batches if necessary, until browned. Transfer to a bowl.

Stir-fry the vegetables:

  • Add the remaining oil to the hot skillet, then add the onion and cook for 1 minute.
  • Stir in the garlic, cumin, and aji amarillo paste and cook for 30 seconds.
  • Add the tomatoes and cook for 1 to 2 minutes, just until they begin to soften but still hold their shape.

Finish and serve:

  • Return the beef to the skillet. Add the remaining soy sauce and beef stock, then toss for 1 to 2 minutes until glossy.
  • Fold in the cilantro and remove from the heat.
  • Serve immediately with hot French fries and white rice.

Notes

  • Slice the beef across the grain for the most tender texture.
  • Keep the tomatoes in large wedges so they do not disappear into the sauce.
  • Reheat leftovers in a hot skillet and add fresh fries just before serving.
