Ingredients

Scale

Caramelized Onion, Mushroom, Apple & Gruyere Bites

Main Ingredients:

  • 1 lb puff pastry, thawed
  • 1 large onion, thinly sliced
  • 4 ounces (113 grams) baby bella mushrooms, sliced
  • 1 1/2 Granny Smith apples, cubed
  • 1 1/2 ounces (42 grams) grated Gruyere cheese

Cooking Fats and Enhancers:

  • 2 tablespoons vegetable oil
  • 2 tablespoons unsalted butter
  • 1 teaspoon granulated sugar

Herbs and Finishing Ingredients:

  • 2 tablespoons minced chives
  • 1/2 teaspoon dried thyme
  • 1 egg, beaten

Instructions

  1. Prepare the oven at 400°F and line two baking sheets with parchment paper for optimal cooking surface.
  2. Transform onions into a rich, golden delicacy by slowly sautéing in oil over low heat for approximately 30 minutes, stirring periodically until they develop a deep caramel color and soft texture.
  3. Utilize the same skillet to sauté mushrooms until they become tender and release their earthy flavors, approximately 5 minutes.
  4. Introduce butter to the skillet and gently cook apple pieces with sugar, creating a tender and slightly caramelized fruit component in about 10 minutes.
  5. Merge the caramelized onions, sautéed mushrooms, and cooked apples into a harmonious mixture, then incorporate Gruyere cheese, finely chopped chives, and fresh thyme for depth of flavor. Season with salt and pepper to enhance the overall taste profile.
  6. Roll out puff pastry and slice into precise 2-inch squares. Arrange these delicate squares on prepared baking sheets, brushing each with beaten egg to achieve a golden sheen.
  7. Carefully spoon the prepared filling onto the center of each pastry square, ensuring an even distribution of ingredients.
  8. Bake the assembled bites for 25 minutes, rotating the pans midway through the cooking process to guarantee uniform golden and crispy results.
  9. Allow the bites to cool slightly before serving, allowing the flavors to settle and the pastry to reach the perfect texture.

Notes

  • Select sweet onions like Vidalia for deeper caramelization and richer flavor profile.
  • Slice mushrooms uniformly to ensure even cooking and consistent texture in the bites.
  • Use cold puff pastry to maintain flakiness and prevent butter from melting before baking.
  • For gluten-free version, substitute puff pastry with almond flour-based pastry or gluten-free puff pastry alternative.
