Savory Gruyère Onion Bites Recipe

Introduction

These Savory Gruyère Onion Bites are a perfect blend of caramelized onions, earthy mushrooms, crisp apples, and melted cheese wrapped in flaky puff pastry. They make an elegant appetizer or a satisfying snack for any occasion.

Ingredients

• 2 tbsp vegetable oil
• 1 large onion, thinly sliced
• 4 oz baby bella mushrooms, sliced
• 2 tbsp unsalted butter
• 1 ½ Granny Smith apples, cubed
• 1 tsp granulated sugar
• 1 ½ oz grated Gruyère cheese
• 2 tbsp minced chives
• ½ tsp dried thyme
• 1 lb puff pastry, thawed
• 1 egg, beaten

Instructions

1. Step 1: Heat the vegetable oil in a skillet over medium-low heat. Add the sliced onion and cook slowly for 20-30 minutes until tender and golden brown. Remove from heat and set aside.
2. Step 2: In the same skillet, melt the butter over medium heat. Add the sliced mushrooms and cook for 5-7 minutes until browned. Stir in the cubed apples and sugar, cooking for another 5-8 minutes until the apples are tender but not mushy. Combine this mixture with the caramelized onions in a bowl.
3. Step 3: Add the grated Gruyère cheese, minced chives, and dried thyme to the bowl with the onions, mushrooms, and apples. Gently mix until evenly combined.
4. Step 4: Roll out the thawed puff pastry on a lightly floured surface. Cut into approximately 2-inch squares or rectangles. Spoon about one tablespoon of the filling onto the center of each pastry piece, leaving a border around the edges.
5. Step 5: Bring the edges of each pastry piece up and pinch them together in the center to form a parcel. Arrange the parcels on a baking sheet lined with parchment paper. Preheat the oven to 400°F (200°C). Brush the tops of the pastries with the beaten egg wash. Bake for 15-20 minutes until puffed and golden brown.

Tips & Variations

• For extra flavor, sprinkle a pinch of black pepper or smoked paprika into the filling before assembling the bites.
• You can substitute Gruyère with Swiss or Fontina cheese for a similar melty texture and taste.
• If you prefer a sweeter touch, add a drizzle of honey over the filling before folding the pastry.
• Make sure the puff pastry stays cold before baking to ensure maximum flakiness.

Storage

Store any leftover onion bites in an airtight container in the refrigerator for up to 3 days. To reheat, place them on a baking sheet in a 350°F (175°C) oven for about 8-10 minutes until warmed through and the pastry crisps up again. Avoid microwaving to keep the pastry flaky.

Vegetables & Fruits

• 1 large onion, thinly sliced
• 4 oz baby bella mushrooms, sliced
• 1 ½ Granny Smith apples, cubed
• 2 tbsp minced chives

Dairy

• 2 tbsp unsalted butter
• 1 ½ oz grated Gruyère cheese
• 1 egg, beaten

Pantry & Spices

• 2 tbsp vegetable oil
• 1 tsp granulated sugar
• ½ tsp dried thyme
• 1 lb puff pastry, thawed

Instructions

1. Caramelize the onions: Heat vegetable oil in a skillet over medium-low heat. Add sliced onion and cook slowly for 20-30 minutes, stirring occasionally, until they become tender and golden brown. Remove from heat and set aside.
2. Sauté mushrooms and apples: In the same skillet, melt the unsalted butter over medium heat. Add sliced mushrooms and cook for 5-7 minutes until browned. Stir in the cubed Granny Smith apples and granulated sugar, cooking for another 5-8 minutes until apples are tender but still hold their shape. Combine with the caramelized onions in a mixing bowl.
3. Assemble filling: To the bowl containing the caramelized onions, mushrooms, and apples, add grated Gruyère cheese, minced chives, and dried thyme. Gently mix all ingredients together until evenly distributed for a flavorful filling.
4. Prepare puff pastry: On a lightly floured surface, unroll the thawed puff pastry sheet. Using a sharp knife or pastry cutter, cut the pastry into approximately 2-inch squares or rectangles. Place about a tablespoon of the prepared filling onto the center of each pastry piece, leaving a border around the edges.
5. Shape and bake: Bring the edges of each pastry square up and pinch them together at the center to form a neat parcel. Arrange the parcels on a baking sheet lined with parchment paper. Preheat the oven to 400°F (200°C). Brush each pastry parcel generously with beaten egg wash to achieve a golden glaze. Bake for 15-20 minutes until the pastry is puffed, flaky, and golden brown. Remove from oven and allow to cool slightly before serving.

Notes

• Caramelizing onions requires patience; cooking them low and slow prevents burning and develops deep sweetness.
• Ensure apples remain slightly firm for texture contrast; avoid overcooking to prevent mushiness.
• Use cold puff pastry for easier handling and better puff during baking.
• Egg wash helps achieve an appealing golden color and glossy finish on the pastry.
• These bites can be prepared ahead of time and baked just before serving for convenience.
