Ingredients
Vegetables
- 1 bunch asparagus (about 12 spears), trimmed
- 2 large yellow onions, thinly sliced
- 1 tbsp olive oil
- Salt and pepper, to taste
Dairy
- 1 cup shredded Gruyère cheese
- 1 egg, beaten (for egg wash)
Pastry
- 1 package puff pastry sheets (usually 2 sheets), thawed
Instructions
- Prep the Vegetables: Preheat your oven to 400°F (200°C). Trim the woody ends off the asparagus spears and set aside.
- Caramelize the Onions: In a large skillet, heat olive oil over medium-low heat. Add the thinly sliced onions, a pinch of salt, and cook slowly, stirring occasionally, until onions are golden brown and caramelized, about 25-30 minutes. Remove from heat.
- Prepare Puff Pastry: Roll out the puff pastry sheets on a lightly floured surface into rectangles approximately 4×6 inches. Cut into 12 equal pieces if not already pre-portioned.
- Assemble Bundles: Place a spoonful of caramelized onions in the center of each pastry piece. Next, sprinkle shredded Gruyère cheese over the onions. Lay 2 asparagus spears atop each bundle.
- Wrap and Seal: Fold the puff pastry up and around the asparagus and fillings to form a tight bundle, pinching the edges together to seal completely.
- Apply Egg Wash: Brush each parcel with the beaten egg to help achieve a glossy and golden finish when baked.
- Bake: Transfer the bundles onto a parchment-lined baking sheet, spacing them evenly. Bake in the preheated oven for 18-22 minutes or until the pastry is puffed, golden brown, and crisp.
- Serve Warm: Remove from the oven and let cool slightly before serving. Enjoy warm as an appetizer or side dish.
Notes
- The Gruyère cheese can be substituted with Swiss or mozzarella if preferred.
- Make sure the puff pastry is well chilled before rolling out to get the best flaky texture.
- For a vegetarian option, this recipe as-is qualifies; to make it vegan, substitute puff pastry and cheese with vegan versions.
- Caramelizing onions takes time but greatly enhances the flavor; don’t rush the process.
- These bundles can be made ahead and baked just before serving for convenience.
