Instructions

Caramelize the Onions: In a large skillet over medium heat, melt the butter until it foams, about 1 minute. Add the thinly sliced onions and stir to coat evenly. Cook over medium heat for 20-25 minutes, stirring occasionally, until they turn deep golden brown and develop a rich, sweet flavor.
Add Liquid and Seasonings: Pour in the beef stock and add the Worcestershire sauce, stirring well. Cook for another 3-4 minutes until the liquid reduces slightly, then remove from heat and let cool for 5 minutes. Stir in the softened cream cheese, thyme leaves, salt, and pepper until the mixture is well combined and smooth.
Prepare the Pastry: Preheat your oven to 400 degrees Fahrenheit (200 degrees Celsius). Line a standard muffin tin with the 12 puff pastry squares, pressing them gently into the cups so they form shells.
Brush and Fill: Brush the tops of each pastry cup with the beaten egg to achieve a golden, glossy finish. Spoon the caramelized onion and cheese mixture evenly into each pastry cup, filling them about three-quarters full, then sprinkle the remaining shredded Gruyère cheese generously over each filled cup.
Bake: Bake for 12-15 minutes until the pastry is puffed, golden brown, and the cheese is bubbling and lightly browned on top. Remove from the oven and let cool for 2-3 minutes before serving.
