Ingredients

• 3 tablespoons unsalted butter
• 4 medium yellow onions
• 1 teaspoon sugar
• 1 tablespoon balsamic vinegar
• 1 teaspoon salt
• 0.5 teaspoon black pepper
• 1 teaspoon fresh thyme leaves
• 1 package store-bought puff pastry sheets
• 1 cup Gruyère cheese
• 1 large egg
• 1 tablespoon water

Directions

Step 1

Peel and thinly slice the yellow onions.

Step 2

In a large skillet, melt the unsalted butter over medium heat.

Step 3

Add the sliced onions to the skillet and stir to coat in butter.

Step 4

Sprinkle the onions with the sugar and cook, stirring occasionally, for about 25-30 minutes until they are golden brown and caramelized.

Step 5

Add the balsamic vinegar, salt, black pepper, and fresh thyme leaves to the onions. Stir well and cook for an additional 2 minutes. Remove from heat and allow to cool.

Step 6

Preheat your oven to 400°F (200°C) and line two baking sheets with parchment paper.

Step 7

Roll out the thawed puff pastry sheets on a lightly floured surface. Cut the sheets into 2-inch squares using a sharp knife or pizza cutter.

Step 8

Place the puff pastry squares onto the prepared baking sheets, ensuring they are evenly spaced apart.

Step 9

Spoon a small amount of the caramelized onion mixture (about 1 teaspoon) onto the center of each square.

Step 10

Sprinkle a small pinch of shredded Gruyère cheese on top of the onion mixture on each square.

Step 11

In a small bowl, whisk together the egg and water to create an egg wash. Brush the edges of each puff pastry square with the egg wash.

Step 12

Bake in the preheated oven for 12-15 minutes, or until the pastry is puffed and golden brown.

Step 13

Remove from the oven and allow the French Onion Bites to cool slightly before serving.
