Ingredients:

  1. 4 tablespoons - butter
  2. 1 1/2 - large yellow onion thinly sliced
  3. 1/2 - large yellow onion minced
  4. - kosher salt
  5. 1 tablespoons - olive oil
  6. 1/2 cups - plus 1 tablespoon heavy cream
  7. 2 - 6-inch sheets frozen puff pastry
  8. 1 - egg yolk beaten
  9. 3 tablespoons - minced chives

Directions:

Preheat oven to 400 degrees F and remove puff pastry from freezer. Melt butter in a large saute pan over medium heat. Add sliced onions and season with a pinch of salt. Cook, stirring, until onions caramelize but retain some bite, about 15 minutes.

Meanwhile, heat oil in a small pan over medium heat. Add minced onions and saute until softened but not browned, about 3 minutes. Add all but 1 tablespoon of cream and bring to a boil. Reduce heat and simmer gently until onions are tender and cream tastes of onion, about 5 minutes.

Use a blender or food processor to puree until smooth. Season with salt to taste.

Line two baking sheets with parchment and place 1 sheet of puff pastry on each. Mix yolk with remaining cream and brush mixture over pastry. Place in oven and bake until puffy and lightly golden, about 10 minutes.

Spoon 3/4 of onion puree evenly over both sheets of pastry, leaving a 1/2-inch border all around. Spread caramelized onions over puree. Bake until topping gently sets and dough is a deep gold at edges, 12 to 15 minutes.

Before serving, drizzle more puree over tarts and garnish with a sprinkling of chives.
