Caramelized Onion Tart

Pictures will be added later!

Meals at my parents house always become bigger and more intensive as the day progresses.  We had our neighbors, Tim and Paul, over for dinner and the menu planning started at 8am.  Poppie (my dad) wanted to make Pernil which is a pork dish from Puerto Rico.  During the morning we added collard greens and an onion tart to the menu. While we were out shopping we added arepas (store-bought not homemade).

The onion tart is easy to make just time consuming. You have to cooking the sliced onions over low heat for two hours before the tart bakes for 20 minutes in the oven.  While the onions are cooking prepare the tart dough.  Then you drain the onions and place them in the tart crust.  Then the Gruyere cheese is layered on before the mixture of cream, egg yokes, nutmeg, salt and pepper.  After the tart bakes for 10 minutes the parmesan cheese is sprinkled on and baked for another 10 minutes. 

This tart is sweet and savory with a delicious mixture of cheese, cream, and crust.  I hope you enjoy it as much as our family and friends did.

Caramelized Onion Tart

1/4 EVOO

2 pounds sweet onions (thinly sliced)

2 teaspoons garlic, minced
2 tablespoons balsamic vinegar

1 cup shredded Gruyere Cheese

1 cup cream

6 egg yokes

1/4 teaspoon nutmeg

1/2 teaspoons salt

1/4 teaspoon black pepper

1/2 cup parmesan cheese, grated
1/2 the recipe for Mom's Pie Crust without the sugar

Heat the EVOO in a large sauce pan over medium heat.  When the oil is ready add the onions and garlic.  Turn the heat to low and cook for about 2 hours, stirring periodically with a wooden spoon, until the onions are soft and caramel in color.  While the onions are cooking prepare the tart crust. After about an hour add the balsamic vinegar to the onions. When the onions are cooked strain them and discard any extra liquid. Transfer the onions to the tart shell and spread them around evenly.  Preheat the oven to 400 degrees. 

Next layer on the Gruyere cheese.  Mix the cream, egg yokes, nutmeg, salt, and pepper together in a medium bowl before spreading the mixture on top of the cheese.  Bake the tart for 10 minutes before sprinkling with the parmesan cheese.  Bake for another 10 minutes for until the tart is set.  Let it rest for 10 minutes before slicing. Enjoy!
