1-hour 25-Minute recipe Serves 48


Prep: 25 mins | Cook: 45 mins
  • 1

    Heat a large non-stick frying pan over medium-high. Add butter, onion, 2 tsp thyme, mustard powder, salt and black pepper. Cook, stirring often, until onion is golden, about 15 minutes.

  • 2

    Stir in broth. Cook until broth has mostly evaporated and onions are soft and dark caramel in colour, about 20 minutes. Set aside to cool slightly.

  • 3

    Position rack in centre of oven, then preheat to 425°F.

  • 4

    Unroll puff pastry sheets on a cutting board. Cut each sheet into twenty-five squares, each about 2-in. Press pieces of pastry into two 24-cup mini muffin pans. (You will have two extra squares.) Chill in refrigerator for 15 minutes. Fill each puff pastry cup with about 2 tsp onion mixture. Sprinkle cheese overtop.

  • 5

    Bake until pastry is golden and puffed, and cheese is bubbling, about 8 to 10 minutes. Sprinkle remaining 1 tsp thyme overtop. Serve immediately.
