Traditional Carne Asada Tacos

Why This Traditional Carne Asada Tacos Works

During the long rest in the marinade, the soy sauce and citrus juices soak deep into the flank steak. The salty soy starts to loosen up the muscle fibers, and the lime and orange juice gently rough up the outside of the meat. Garlic, jalapeño, and cilantro spread through all the little gaps. By the time the steak goes on the grill, it’s already seasoned all the way through and a bit more relaxed, so it doesn’t tighten up as hard in the heat.

On the hot grill, the outside of the steak browns fast while the inside stays juicy. Since the meat sat in liquid and oil, the surface doesn’t dry out as quickly. After grilling, the short rest lets the hot juices settle back into the steak instead of running out on the cutting board. Slicing thinly against the grain cuts through the long fibers, so each piece feels tender, not chewy. Warm tortillas bend instead of cracking, and the juicy steak, crisp onion, fresh cilantro, and soft queso fresco all stay in place and eat easily as a taco.

Mistakes To Avoid

Letting the steak sit in the marinade for only a short time leaves the inside of the meat tasting plain while the outside is sharp and salty. The liquid never really soaks into the thicker parts, so the tacos end up with strips that taste uneven from bite to bite.

Grilling the steak on low or medium heat keeps it on the grill too long and slowly dries it out. The outside never gets that quick char, and the inside turns gray and chewy instead of staying juicy with a slight pink center.

Cooking the steak past medium, especially with flank, makes the meat tough and stringy. The muscle fibers tighten up, so even thin slices feel dry and take a lot of chewing in the taco.

Slicing the steak with the grain instead of against it leaves long, rope-like pieces that are hard to bite through. The tacos become messy because the meat pulls out of the tortilla in big strips instead of breaking apart easily.
