Whisk lime juice, olive oil, garlic, chili powder, cumin, oregano, paprika, salt, and pepper.
Pat steak dry. Coat with the marinade in a bowl or bag. Chill 15–20 minutes.
Heat a large skillet over medium-high. Add the neutral oil until shimmering.
Sear the steak 3–4 minutes per side until nicely browned and medium-rare.
Rest the steak 5 minutes. Slice thinly against the grain.
Warm tortillas in a dry pan or over a flame until pliable.
Assemble tacos with steak, onion, cilantro, avocado, salsa, cotija, and jalapeño.
Serve immediately with extra lime and hot sauce, if desired.
Notes
Try chipotle powder instead of smoked paprika for a deeper, smoky kick. Leftover steak keeps 3 days; rewarm gently or serve chilled in bowls.This recipe is an original creation inspired by classic Easy Steak Tacos Recipe flavors. All ingredient ratios and instructions are independently developed.
