In a large bowl, combine the steak with beer, garlic powder, onion powder, paprika, black pepper, oregano, salt, orange juice, olive oil, sliced onion, and cilantro.
Mix well so the meat is evenly coated.
Marinate in the fridge for at least 1 hour or overnight for best flavor.
Preheat a grill or skillet over medium-high heat.
Grill or pan-sear the steak to your desired doneness, flipping once during cooking.
Let the cooked steak rest for a few minutes before slicing against the grain.
Serve with tortillas, grilled jalapeños, queso fresco, salsa, and a squeeze of lime.
Enjoy!
