Ingredients

  • 8 bacon slices, chopped
  • 5 cups sliced onions (about 3 large)
  • 1 large egg
  • 1/2 cup sour cream
  • 1 teaspoon salt
  • 1/2 teaspoon ground black pepper
  • Pinch of ground nutmeg
  • 1 13.8-ounce tube refrigerated pizza dough
  • 1/4 teaspoon caraway seeds

Method

  • Preheat oven to 375°F. Saute bacon in heavy large skillet over medium-high heat until slightly crisp. Drain all but 1 tablespoon bacon drippings from skillet. Add onions to bacon and saute over medium heat until onions are very tender but not brown, about 20 minutes. Cool.
  • Whisk egg, sour cream, salt, pepper, and nutmeg in large bowl to blend. Stir in cooled onion mixture.
  • Roll pizza dough out on lightly floured surface to 13x10-inch rectangle. Transfer to baking sheet. Spread onion mixture over dough, leaving 1/2-inch plain border around edges. Sprinkle with caraway seeds.
  • Bake tart until onion custard is set and crust is golden brown around edges and brown on bottom, about 25 minutes.
