Caramelized Onion & Fontina Savory Tart

Main ingredient

Caramelized Onion

Cook time


Serving size



  • 2 Medium Vidalia Onions, cut into ⅛” petals
  • 3 Tbsp Tuscan Herb Infused Olive Oil, divided
  • 1 Refrigerated Pie Dough
  • 1 tsp Herb & Garlic Dipper
  • 1 cup Shredded Fontina Cheese
  • 2 tsp Sweet Basil Balsamic Vinegar

Recipe Preparation

  1. Preheat oven to 350° F.
  2. In a 12” skillet over medium-low heat add 2 Tbsp olive oil, once hot add the onions. Cook stirring occasionally until onions caramelize and are sweet, about 45-50 minutes, taking care that onions do not burn.
  3. On a sheet of parchment paper roll out dough into a circle that is about ¼” thick.
  4. Sprinkle cheese over pie dough leaving about 1” border then spread out onions over cheese.
  5. Gently begin to crimp or pleat the dough around the onions so it forms a little crust.
  6. Move tart to a baking sheet and drizzle with remaining tablespoon of olive oil. Bake until the crust is golden brown, about 30-35 minutes.
  7. Finish with Sweet Basil Balsamic Vinegar. Enjoy!
