These easy Mexican street tacos feature juicy, citrus-marinated steak tucked into warm corn tortillas and topped with fresh onion, cilantro, and a squeeze of lime. Perfect for weeknights or casual gatherings.
In a bowl, whisk together salt, pepper, cumin, chili powder, garlic powder, lime juice, orange juice, and olive oil to make the marinade.
Place steak in a shallow dish or zip-top bag and pour marinade over it. Turn to coat well, then refrigerate for 30 minutes up to 2 hours.
Preheat a grill or cast-iron skillet over high heat until very hot. Pat the steak dry to promote a good sear.
Cook steak for 3 to 4 minutes per side for medium-rare, or to desired doneness. Transfer to a cutting board and rest for 5 minutes.
Warm tortillas on the grill or directly over a gas flame for 10 to 15 seconds per side until pliable and lightly charred.
Slice steak thinly against the grain, then chop into bite-size pieces.
Assemble tacos: fill tortillas with steak and top with onion, cilantro, cotija, radishes, and jalapeño. Finish with a squeeze of lime and serve immediately.
Notes
For extra flavor, char the tortillas and warm them in a damp towel to keep them pliable. Swap steak for chicken or mushrooms for an easy variation.
