How to Make Flank Steak Tacos

Step 1: In a large bowl, whisk together olive oil, lime juice, minced garlic, chili powder, kosher salt, and black pepper. Transfer the marinade to a zip-top bag and add the flank steak. Seal the bag and marinate at room temperature for 20 to 30 minutes or refrigerate for up to 24 hours. Let the steak sit out for 30 minutes before grilling.
Step 2: Remove the steak from the marinade and pat dry with paper towels. Season both sides generously with kosher salt and black pepper.
Step 3: Preheat grill to medium-high heat. Place the steak on the grill and cook for about 6 minutes per side for medium doneness, using a meat thermometer to check for 130°F for medium-rare, 140°F for medium.
Step 4: Remove the steak from the grill and let it rest for 5 to 10 minutes to allow juices to redistribute.
Step 5: Slice the steak thinly against the grain for maximum tenderness.
Step 6: While the steak is resting, prepare your desired toppings, such as diced tomatoes, avocado, onions, or cilantro lime crema.
Step 7: Warm the corn tortillas and place the sliced flank steak on top. Add freshly chopped cilantro, cotija cheese, and any additional toppings. Serve immediately for the best flavor experience.
