Apple & Cheddar Upside Down Tart with Caramelized Rum Onions
Apple & Cheddar Upside Down Tart with Caramelized Rum Onions is a delightful appetizer made with crisp apples, sharp cheddar cheese, puff pastry, and caramelized rum onions.
Ingredients
- 3 tbsp Unsalted butter
- 2 medium Yellow onions, sliced thinly
- 2 tbsp Flor de Caña
- 2 to 3 medium Envy Apples, sliced thinly
- 3/4 cup Shredded cheddar cheese
- 1 sheet Puff pastry, defrosted
- 1 large Egg, whisked
- Fresh thyme, for garnish
Instructions
- In a large skillet preheated to medium-low, melt the butter. Add the thinly sliced onions and cook, stirring occasionally, until they become soft and golden brown. Pour the Flor de Caña into the skillet and stir. Cook for an additional 2 to 3 minutes until the rum is absorbed. Remove from the heat and set aside.
- Line a baking sheet with parchment paper. Place 3 to 4 sliced apples in a row slightly overlapping. You will end up with 9 equally sized rectangles on the baking sheet to create the tarts. Next, top the apple slices with shredded cheese and caramelized rum onions.
- Roll out a sheet of puff pastry and cut them into 9 equally sized rectangles. Place a puff pastry rectangle on top of each apple mixture. Using a fork, crimp the sides to keep the puff pastry from rising. Brush the tops with egg wash and bake for about 20 minutes or until golden brown.
- Once baked, remove the tarts from the oven and carefully flip each one over using a spatula. Allow the tarts to cool slightly before serving. Best enjoyed warm!
