Pear and Blue Cheese Tarts

Ingredients

• 1 tablespoon butter
• 4 large onions, thinly sliced
• 3 pears, finely diced
• 2 cups crumbled blue cheese
• 3/4 cup chopped walnuts
• 30 (2 inch) frozen miniature tart shells

Directions

Heat butter in a large skillet over medium-high heat; cook and stir onions until brown, soft, and sweet, 40 to 45 minutes. Let onions cool for a few minutes.

Preheat oven to 375 degrees F (190 degrees C). Remove tart shells from freezer and place on baking sheets lined with parchment paper.

Combine caramelized onions with pears, blue cheese, and walnuts in a large bowl. Spoon pear-blue cheese filling into still-frozen tart shells.

Bake in the preheated oven until the filling is hot and melted and the pastry shells are lightly browned, 15 to 20 minutes. Serve warm or cooled.
