Carne asada street tacos are the perfect weeknight taco recipe! Tender grilled skirt steak piled high on a warm corn tortilla with chopped onions, cilantro, and cotija.
Whisk together the olive oil, garlic, vinegar, orange juice, spices, salt, and cilantro together until smooth.
Place the steak and sliced onions in a large dish or on a rimmed baking sheet. Pour the marinade over the steak and really work the marinade into the steak with your hands. Cover and marinate for at least 1 hour, up to 12 hours.
Preheat a grill to medium-high heat. Make sure the grates are clean and oiled. Remove the steak from the marinade and grill for 3-4 minutes per side.
Let the steak rest for 10 minutes before dicing into 1/2" pieces. Serve on warm corn tortillas topped with onion, cilantro, and cotija cheese with lime wedges on the side.
