This steak is tender and deeply flavored with a simple blender marinade of onion, garlic, jalapeños, and beer. These beef tacos, created by San Antonio chef Johnny Hernandez, are so simple to make and so flavorful, they will become your favorite new recipe for the grill. Hernandez marinates top sirloin steaks in a pureed mixture of white onions, garlic, chopped jalapeños, salt, black pepper, beer, and water for several hours. The blender marinade infuses the meat with flavor and also helps tenderize it. Hernandez grills the steak for a few minutes on both sides to medium-rare, then lets the meat rest for a few minutes before slicing to seal in the juices. The steak is sliced thinly and served on tortillas topped with cilantro and red onion, and lime wedges and salsa on the side. Start the meal with tortilla chips and homemade guacamole (and margaritas) for an easy yet impressive menu.

Ingredient Checklist


Instructions Checklist
  • Place sirloin steaks in a large ziplock plastic freezer bag. Process white onions, garlic cloves, seeded and chopped jalapeños, kosher salt, black pepper, beer, and water in a blender until smooth. Pour over steaks; seal bag, and turn to coat. Chill 3 hours.

  • Preheat grill to medium-high (about 450°F). Remove steak from marinade; discard marinade. Place steak on oiled grates, and grill sirloin, uncovered, until a thermometer inserted in thickest portion registers 145°F or to desired degree of doneness, 5 to 6 minutes per side for medium-rare. Let steak stand 3 minutes before diagonally slicing across the grain.

  • Toss together cilantro leaves and red onion slices. Heat tortillas on a comal (flat griddle) or according to package directions.

  • Divide steak among tortillas; top with cilantro mixture. Serve with limes and salsa.

Test Kitchen Tip

To give the Grilled Sirloin Tacos an extra kick of heat, Hernandez suggests dipping the cut sides of fresh lime slices in ground chile powder.
