Sauteed steaks flavored with a garlic rub and the smoky-sweet taste of caramelized onions are a satisfying, easy-to-make main course.


  • 2 boneless sirloin steaks (each about 1 pound and ½ inch thick)

  • 1 large garlic clove, minced and mashed into a paste

  • 5 ½ tablespoons extra-virgin olive oil

  • Coarse salt and freshly ground pepper

  • 1 ¾ pounds small red onions, halved lengthwise and cut into ⅓-inch-thick wedges (keeping root ends intact)

  • ½ teaspoon sugar

  • 3 tablespoons balsamic vinegar


  1. Place steaks on a large plate, and rub with garlic paste and 2 tablespoons oil, coating completely. Season generously with salt and pepper. Set aside to marinate 15 minutes at room temperature.

  2. Meanwhile, in a large skillet, heat 2 tablespoons oil over medium-high heat until hot and just starting to smoke. Reduce heat to medium; add onions, and cook, stirring occasionally, until softened and golden brown, about 7 minutes. Add sugar, vinegar, and 2 tablespoons water; simmer, stirring occasionally, until onions are tender, about 3 minutes more. Transfer onions to a bowl, and season with salt and pepper. Set aside.

  3. Wipe skillet clean. Heat remaining 1 1/2 tablespoons oil in skillet over high heat until hot but not smoking. Cook steaks until golden brown, about 2 minutes per side for medium-rare. Transfer to a cutting board, and let rest 5 minutes before slicing.
