Onion Focaccia

Source: Everyday Food, January/February 2011


  • 3 tablespoons plus 1 teaspoon extra-virgin olive oil
  • 2 pounds homemade or store-bought pizza dough
  • 2 large red onions, thinly sliced
  • Coarse salt and ground pepper
  • 1 tablespoon cider vinegar
  • 1/2 cup grated Pecorino Romano
  • 1/2 to 1 teaspoon red-pepper flakes


  1. Preheat oven to 425 degrees. Coat an 11-by-17-inch rimmed baking sheet with 2 tablespoons oil. Place dough on sheet, stretching to fit (if dough springs back, let rest 20 minutes and repeat). Drizzle edges with 1 tablespoon oil. Cover with plastic wrap and let sit 15 minutes.

  2. Meanwhile, in a large skillet, heat
    1 teaspoon oil over medium-high. Add
    onions and season with salt and pepper.
    Cook, stirring occasionally, until onions
    are tender and golden brown in spots,
    12 minutes. Add vinegar and cook,
    stirring and scraping up browned bits
    with a wooden spoon, 1 minute.

  3. Remove plastic from dough. With
    your fingertips, poke dimples all over
    dough, then top with cheese, browned
    onions, and red-pepper flakes. Bake
    until golden brown around edges, about
    30 minutes. Let cool on sheet 5 minutes.
    Cut into 20 pieces and serve warm
    or at room temperature.

Cook's Note

To store, wrap cooled focaccia in plastic and keep at room temperature, up to 2 days.

    Made this to last night and we loved it. Carmalized onions with red pepper flakes and pecorino cheese - yum. We like spicy so added more red pepper flakes than recipe suggests. Otherwise a nice pre-dinner snack with a nice dry white wine.
