Ingredients

Scale
  • 1 lb sirloin steak, thinly sliced against the grain
  • 2 tbsp soy sauce
  • 1 tbsp red wine vinegar
  • 3 cloves garlic, minced
  • 1 medium red onion, sliced into thick wedges
  • 2 medium tomatoes, cut into wedges
  • 1 small bunch fresh cilantro, chopped
  • 1–2 fresh jalapeños or yellow chili peppers, sliced thin (optional)
  • Salt and freshly ground black pepper, to taste
  • 2 tbsp vegetable oil or avocado oil
  • 3 medium yellow potatoes, peeled and cut into fries or thick sticks
  • 2–3 tbsp vegetable oil (for frying potatoes)
  • Optional: sprinkle of smoked paprika or garlic powder for extra flavor

Instructions

  1. Peel and cut the potatoes into fries or thick sticks about 1/2 inch thick. Soak in cold water for 20 minutes to remove excess starch. Drain and pat dry completely with paper towels.
  2. Bring a medium pot of salted water to a boil. Add the dried potatoes and cook for 5 minutes until just tender but still firm. Drain well and set aside to cool slightly.
  3. Heat 2-3 tbsp vegetable oil in a large skillet over medium-high heat. Fry potatoes in batches without overcrowding until golden and crispy, about 6-8 minutes per batch. Remove with a slotted spoon and drain on paper towels. Season immediately with salt and optional smoked paprika.
  4. In a bowl, combine sliced sirloin, soy sauce, red wine vinegar, minced garlic, salt, and pepper. Toss to coat and let sit for 10-15 minutes.
  5. Heat 1 tbsp vegetable oil in a large hot skillet or wok over high heat. Add marinated beef in a single layer and sear for 2-3 minutes without stirring. Flip and cook another 1-2 minutes until browned but tender. Remove beef and set aside.
  6. In the same pan, add more oil if needed. Add red onion and cook for 2 minutes until slightly softened but still crisp. Add tomato wedges and sliced chili peppers if using. Cook for 1-2 minutes, stirring gently.
  7. Return beef to the pan with veggies. Stir and cook for 1 minute to blend flavors. Adjust seasoning with salt, pepper, or extra vinegar if desired.
  8. Serve beef stir fry with crispy potatoes on the side or mixed in. Garnish with fresh chopped cilantro.

Notes

Soaking and drying potatoes before frying is key to achieving crispiness. Use high heat to sear beef quickly to keep it tender. Avoid overcrowding the pan when frying potatoes or cooking beef to prevent sogginess. Marinate beef briefly to add flavor without making it mushy. Reheat crispy potatoes in the oven to restore crispiness.
