Pear And Blue Cheese Pastry Triangles - cooking recipe

Ingredients

3 tablespoons butter
1 tablespoon olive oil
4 sweet onions, thinly sliced
salt and pepper to taste
1 (17.5 ounce) package frozen puff pastry, thawed
2 firm pears, peeled, quartered, and sliced
3/4 cup crumbled blue cheese

Preparation

Preheat oven to 375 degrees F (190 degrees C). Line two baking sheets with parchment paper.
Melt the butter and olive oil in a large skillet over medium heat. Stir the onions into the butter, and cook until the onions have softened and caramelized to a deep, golden brown, 30 to 40 minutes. Stir frequently as the onions cook to keep them from burning. Once done, season with salt and pepper, and set aside to cool.
Use a sharp knife to cut each sheet of puff pastry into 9 squares. Cut each square in half diagonally to yield 36 triangles. Place the triangles onto the prepared baking sheets, and top with the caramelized onions, pears, and 1 teaspoon of blue cheese.
Bake in the preheated oven until the pastry is puffed and golden brown, 20 to 30 minutes. Allow to cool to room temperature before serving.
