Ingredients

  • 2 tablespoons unsalted butter
  • 1 tablespoon olive oil
  • 1/2 onion sliced
  • Salt and pepper to taste
  • 2 sheets puff pastry thawed according to package instructions
  • 1 large egg plus 1 teaspoon water beaten
  • 2 large tomatoes thinly sliced
  • 1/2 cup pepperjack cheese shredded
  • Fresh parsley and herbs

Instructions

  • Melt butter and olive oil in skillet over medium heat.
  • Add sliced onions to pan, season with salt and pepper and cook, continuing to stir, until tender and golden brown (this process takes a while- up to 20 minutes) then set aside.
  • Preheat oven to 425 degrees.
  • Using a round cookie cutter, cut circles of dough out of puff pastry and place on a parchment paper lined baking sheet.
  • Brush egg wash on each pastry circle then top each with a tomato slice in the direct center.
  • Next add caramelized onions on top of each tomato slice and sprinkle shredded cheese.
  • Bake for 16-20 minutes or until tarts are puffy and golden brown and cheese has turned golden and melty. Top with parsley and herbs if you would like. Cool for a few minutes then serve.

Notes

Use a round cookie cutter - They create uniform circles ensuring that you have the same size for each tart and also make the job easier.  It also helps with uniform baking.  If you don't have a round cookie cutter, you can use the back of an empty can.
Don't skip the egg wash - The egg wash on the puff pastry will give a beautiful glossy and golden brown color once the tarts are baked.  This is a crucial step.
