French Onion Soup Tarts
As Prepared by Lady Indana Ward
4 medium onions
1 stick butter
1/2 cup broth, beef or vegetable
1/2 cups shredded mozzarella
1/2 cup shredded swiss
1 package puff pastry cups
Slice the onions into long, thin slices.
Melt butter in the bottom of a large stock pot. Slowly caramelize the onions in the butter, stirring nearly constantly towards the end, until they are a nice deep brown. They will reduce in size a bunch. This will take a long time, possibly 50 minutes or more.
Once the onions are fully caramelized, deglaze the pan with the broth. Set the onions aside to cool.
Once the onions have cooled completely, fill each puff pastry cup with onions
Sprinkle mozzarella and swiss cheese on top of the onions.
Bake at 400 degrees until cheese is melted and brown.
