French Onion Soup Mini Pies

Ingredients

  • 6 tbsp butter
  • 3 yellow onions thinly sliced
  • 1 cup White Wine
  • 3 garlic
  • 1 cup cremini mushrooms
  • 2 tbsp Dried Thyme
  • 2 tbsp Sage
  • 1 cup broth
  • 3/4 cup Heavy Cream
  • Salt
  • pepper
  • cup gruyere cheese
  • 1 puff pastry
  • 1 egg beaten

Equipment

  • Large Skillet
  • Oven
  • Baking Tray

Instructions

  1. 1

    In a large skillet, melt butter over medium heat. Add onions and sauté until caramelized, about 5 minutes.

  2. 2

    Stir in garlic, thyme, and sage. Cook for 1-2 minutes until fragrant.

  3. 3

    Deglaze with white wine, scraping up any browned bits. Cook until liquid is absorbed, about 10 minutes.

  4. 4

    Add mushrooms, broth, and heavy cream. Simmer for 15 minutes until slightly thickened.

  5. 5

    Preheat oven to 375°F (190°C). Roll out puff pastry and cut into 16 squares. Fill each with soup mixture.

  6. 6

    Top with shredded Gruyère and a beaten egg. Bake for 20-25 minutes until golden and bubbly.

Ago's Notes

  • Caramelize onions for depth of flavor
  • Use thawed puff pastry for flakiness
  • Bake until golden for a crisp crust

Serve warm and topped with fresh thyme, sea salt, and pepper for the perfect finishing touch.
