Juicy, flavorful flank steak marinated in citrus and Mexican spices is grilled to perfection to create carne asada tacos topped with your favorite street taco toppings!
In a mixing bowl or large measuring cup, combine the minced garlic, lime juice, orange juice, minced jalapeño, chopped cilantro, avocado oil, chili powder, ground cumin, and dried oregano. Mix well.
Place flank steak in a shallow, glass baking dish. Pour marinade over evenly to cover the steak.
Cover with plastic wrap and refrigerate for 2 hours (up to 4 hours).
Bring meat to room temperature by removing from refrigerator 30 minutes before grilling. Season both sides with kosher salt and pepper.
Prepare grill to medium high heat (about 450º). When hot, shake off excess marinade from steak and place onto hot grates. Don't disturb or move steak and allow it to cook for 6 minutes. Flip carefully and cook for another 5-7 minutes or until internal temperature reads 140º (it will cook another 5 degrees or so when resting).
Remove from heat and place onto cutting board to rest.
Meanwhile, heat the tortillas on the grill for 1-2 minutes per side until warmed and slightly charred.
When steak is ready to be sliced, cut against the grain. If the lines of the steak run east to west on a longer cut like flank, then slice north to south. Dice smaller for tacos.
Prepare tacos by layering diced steak onto warm tortillas, then adding toppings like diced onions, fresh lime juice, sliced avocado, jalapeño slices and cotija cheese. Serve and enjoy!!
