These carne asada tacos feature tender, smoky, citrus-marinated grilled flank or skirt steak chopped and piled into warm corn tortillas with fresh pico de gallo, creamy avocado, diced white onion, cilantro, and a squeeze of lime.

Instructions
In a small bowl, whisk together the orange juice, lime juice, olive oil, minced garlic, chopped cilantro, cumin, chili powder, smoked paprika, oregano, salt, black pepper, soy sauce, and jalapeño (if using) until fully combined.
Place the steak in a large zip-lock bag or shallow dish, pour the marinade over it, and refrigerate for at least 2 hours (up to 8 hours). Remove from the fridge 20-30 minutes before grilling to bring to room temperature.
Dice the white onion and soak in cold water for 5 minutes to reduce sharpness, then drain and pat dry. Chop cilantro, prepare guacamole or slice the avocado, and set out all toppings in small bowls.
Preheat an outdoor grill or cast iron grill pan to high heat (450-500°F / 230-260°C). Brush grates or pan lightly with oil and allow to get screaming hot before adding the steak.
Remove the steak from the marinade and pat dry, then grill undisturbed for 3-4 minutes per side for medium-rare (130-135°F / 54-57°C) or 4-5 minutes per side for medium (140-145°F / 60-63°C). Use a meat thermometer to check doneness.
Transfer steak to a cutting board, tent loosely with foil, and rest for 5 minutes. Slice thinly against the grain, then chop into bite-sized pieces about 1/2 inch in size.
Toast each corn tortilla directly over a gas flame (10-15 seconds per side), in a dry hot skillet (30-45 seconds per side), or wrapped in damp paper towels in the microwave (30-45 seconds). Double up corn tortillas for authentic street-style tacos.
Layer doubled corn tortillas with chopped carne asada, drained diced onion, fresh cilantro, pico de gallo, avocado or guacamole, and cotija cheese if using. Finish with a squeeze of lime and hot sauce, then serve immediately.
Notes
Always slice flank or skirt steak against the grain. Look for the direction of the muscle fibers and cut perpendicular to them for tender, easy-to-chew pieces.
Do not marinate longer than 8 hours. The citric acid in orange and lime juice will break down the meat texture and make it mushy if marinated too long.
Pat the steak dry before placing it on the grill. Excess marinade on the surface will steam the meat instead of searing it, preventing that crucial char.
Let the steak rest for at least 5 minutes after grilling. This allows the juices to redistribute and keeps the meat moist when sliced.
Double up corn tortillas for street-style tacos. Using two tortillas per taco prevents tearing and keeps the filling secure.
Skirt steak is thinner than flank steak and will cook faster. Check with a meat thermometer early to avoid overcooking.
For indoor cooking, a cast iron grill pan over medium-high heat is the best alternative to an outdoor grill. It must be very hot before the steak goes on.
The marinade also works with chicken thighs (grill to 165°F / 74°C) or large shrimp (2-3 minutes per side).
Store leftover carne asada in an airtight container in the refrigerator for up to 4 days, or freeze for up to 3 months. Reheat in a hot skillet with a splash of broth.
Do not assemble tacos in advance. Warm tortillas and add toppings only right before serving to prevent sogginess.
