Prep Time: 70 Minutes
Servings: 6

Ingredients:

  • 2 Sheets Puff Pastry
  • 2 pounds Onions, sliced into thicker rings, preferably Vidalia Onions
  • 3 tablespoons Minerva Dairy Unsalted Butter
  • 1 tablespoon Olive Oil
  • 1/4 – 1/2 teaspoon Salt
  • 1 teaspoon Ground Black Pepper
  • 2 Sprigs of Fresh Thyme, plus for garnish
  • 4 tablespoons Creme Fraiche 




directions:

CARAMELIZED ONIONS: 

  1. Melt the butter, then add oil in a large skillet.  Add thick onion slices and turn the heat to medium.  Stir to coat for a bit and do not touch it until you see the onion changing color from the bottom.  You can check by flipping once or twice after 5 to 7 minutes.
  2. This is the beginning of caramelization.  I do not add sugar, but I use sweet yellow onions which will give you an excellent caramelization of onions.
  3. Now, add the thyme, salt, and ground black pepper to the skillet and stir.  Turn the heat to medium-low heat until the onions are completely translucent and caramelized.  It will take around 30 to 40 minutes depending on your stove, skillet, etc.  Remove from heat and allow to cool slightly.

ASSEMBLY:

  1. Preheat oven to 400 degrees Fahrenheit (190C).
  2. Thaw your frozen puff pastry, preferably in the fridge, overnight.
  3. Unfold your pastry only when fully thawed.
  4. Flour your work surface and your rolling pin.  Use restraint with your rolling pin and just slightly roll.  Use a fork and make small punching holes all around the bottom of the puff pastry.
  5. Add Creme Fraiche on the top of the pastry then slightly fold ends of the pastry, as shown on the pic.  If you do not have Creme Fraiche, check notes below.
  6. As you can see on step by step instructions make sure the pastry has four edges in order to hold the onions.  You may make it as traditionally rectangular or bake in the circular baking tart pan.
  7. Bake between 15 and 17 minutes, depending on your oven.  The pastry needs to be golden.
  8. Take it out and allow it to cool down for a minute or two before slicing.

NOTES: 

EASY CREME FRAICHE SUBSTITUTE:

  1. Mix 1 cup heavy cream and 1/4 cup whole milk sour cream together.
  2. I like mixing it in the jar or a container with a fitted lid, but you can pour the misture into a jar as well, cover and let stand in a warm place for about 8 hours.
  3. Then stir and refrigerate for 24 hours before serving
