Ingredients

Instructions

  1. Step 1: In a small bowl, mix 2 tbsp olive oil, 1 tbsp red wine vinegar, 1/4 cup chopped parsley, 1 tbsp chopped oregano, 2 minced garlic cloves, and 1/4 tsp red pepper flakes to make chimichurri. Rub the mixture evenly over 1 lb flank steak and let marinate for 30 minutes at room temperature.
  2. Step 2: Preheat oven to 400°F (200°C). Toss 2 lbs cubed potatoes with 1 tbsp chopped rosemary, 1 tsp salt, and 1/2 tsp black pepper. Spread on a baking sheet and roast for 25 minutes until golden and crispy.
  3. Step 3: Heat a skillet over high heat. Sear the marinated flank steak for 4 minutes per side for medium-rare, or until an internal thermometer reads 130°F (54°C). Rest for 10 minutes before slicing thinly against the grain.
  4. Step 4: Serve the sliced steak over the roasted potatoes, drizzling with extra chimichurri for maximum flavor.
