Ingredients
Scale
- 1 pound (907g) frozen puff pastry, thawed
- 1 large onion, thinly sliced
- 4 oz (113g) baby bella mushrooms, sliced
- 1.5 Granny Smith apples, cubed into ½-inch cubes
- 1.5 oz (43g) Gruyere cheese, grated
- 2 tbsps vegetable oil
- 2 tbsps unsalted butter
- 1 egg, beaten
- 1 tsp granulated sugar
- 0.5 tsp dried thyme
- 2 tbsps chives, minced
Instructions
- Caramelization: Heat vegetable oil in a skillet and slowly transform onions to a rich, golden-brown by stirring occasionally over medium heat for approximately 30 minutes, seasoning with salt.
- Mushroom Preparation: Using the same skillet, sauté mushrooms until tender and moisture is released, then combine with caramelized onions in a mixing bowl.
- Apple Infusion: Melt butter and cook apple cubes with sugar until softened and lightly golden, then fold into the onion and mushroom mixture along with grated Gruyere, minced chives, and thyme leaves.
- Flavor Enhancement: Season the combined mixture with salt and freshly ground black pepper to elevate the taste profile.
- Pastry Arrangement: Preheat oven to 400°F (204°C), thaw puff pastry, and slice into precise 2-inch squares using a sharp knife or pastry cutter.
- Baking Preparation: Line baking sheets with silicone mats, arrange pastry squares evenly, and brush with beaten egg for a glossy finish.
- Filling and Baking: Place one tablespoon of prepared filling in the center of each pastry square, then bake for 25 minutes, rotating pans midway to ensure uniform browning and crispness.
- Serving: Remove from oven and allow bites to cool slightly for easier handling and optimal texture before serving.
Notes
- Slow Caramelize Onions: Take time to develop deep, rich flavor; low and slow cooking is key to achieving golden-brown sweetness without burning.
- Manage Moisture Carefully: Sauté mushrooms thoroughly to prevent excess liquid from making pastry soggy; ensure ingredients are well-drained.
- Choose High-Quality Cheese: Use freshly grated Gruyere for maximum flavor and smooth melting; pre-shredded cheese won’t deliver the same rich taste.
- Perfect Pastry Technique: Brush egg wash lightly and evenly for a professional golden-brown finish; avoid heavy application that can weigh down delicate pastry.
