Recipe type: Entree/Side Dish
Serves: 4
Ingredients
  • 1 tablespoon olive oil
  • 3 medium onions (approximately 4 cups chopped, yields approximately 1.5 cups after caramelization)
  • 2 tablespoons chopped fresh thyme
  • ¾ teaspoon kosher salt
  • ¼ teaspoon black pepper
  • ½ (14.1-ounce) package refrigerated pie dough (such as Pillsbury)
  • ½ cup crumbled feta cheese
  • ½ cup shredded low-fat mozzarella cheese
  • 1 large egg, lightly beaten
  • Fresh thyme leaves for garnish
Instructions
  1. Preheat oven to 425°.
  2. Heat oil in a skillet over medium-high heat. Add chopped onions, thyme, salt, and pepper; cook 20 minutes, stirring occasionally. Keep a watch on the onions and if they start to brown too quickly, turn the heat down to medium.
  3. Roll dough out on a parchment paper-lined baking sheet. Sprinkle feta cheese in center, leaving a 1 and ½-inch border. Top with the caramelized onions. Sprinkle with mozzarella cheese.
  4. Fold piecrust border up and over onion mixture, pleating as you go, leaving a 6-inch-wide opening. Combine egg and 2 tablespoons water; brush over dough.
  5. Bake at 425° for 25 minutes or until golden. Cool for 10 minutes and garnish with fresh thyme leaves.
  6. NOTE: The recipe makes one tart, which lasts me and my husband one night with enough leftover for my lunch the next day. If you're looking to get two night's worth of dinner out of thise recipe, I would double it and make two tarts. Also, if you top the tart with a fried or poached egg, it makes a great brunch dish.
