Cuisine: American
Serves: 6 servings
Ingredients
- 2 large onions, thinly sliced
- 2 tablespoons olive oil
- 1 teaspoon salt
- 1 teaspoon sugar
- 1 cup cream cheese, softened
- 1 cup shredded mozzarella cheese
- 1/2 cup grated Parmesan cheese
- 1 package puff pastry, thawed
- 1 egg, beaten (for egg wash)
Instructions
- Prepare the caramelized onions by heating olive oil in a large skillet over medium-low heat. Add thinly sliced onions, salt, and sugar.
- Cook onions slowly, stirring occasionally, for 20-25 minutes until they turn deep golden brown and become soft and caramelized. Remove from heat and let cool completely.
- Preheat the oven to 400°F (200°C) and line a baking sheet with parchment paper.
- In a medium bowl, mix cream cheese, mozzarella, and Parmesan cheese until well combined.
- Unfold the thawed puff pastry on a lightly floured surface. Cut each sheet into 6 equal squares.
- Place a spoonful of the cheese mixture in the center of each pastry square, leaving a border around the edges.
- Top the cheese with a generous amount of caramelized onions, creating a small mound in the center.
- Carefully fold the corners of the pastry towards the center, pinching slightly to create a "volcano" shape with the onion mixture peeking out.
- Brush each pastry with beaten egg wash, ensuring the edges are well-coated for a golden finish.
- Bake in the preheated oven for 20-25 minutes, or until the pastry is puffed and deep golden brown.
- Remove from oven and let cool for 5-10 minutes before serving. The cheese will be molten, so handle with care.
- Serve warm as an appetizer or side dish, garnishing with fresh herbs if desired.
Tips
- Patience is key when caramelizing onions - low and slow is the secret to achieving that deep, rich golden color and sweet flavor.
- Make sure your cream cheese is truly softened to ensure a smooth, creamy cheese mixture that blends easily.
- Don't overcrowd the baking sheet - give each "volcano" enough space to puff up and crisp beautifully.
- For extra flavor, try adding a pinch of fresh thyme or rosemary to the cheese mixture.
- Let the volcanoes cool slightly before serving to prevent molten cheese burns and allow the pastry to set.
- If the edges start browning too quickly, cover them loosely with aluminum foil during baking.
- These volcanoes are best served immediately while the cheese is still warm and gooey, so time your preparation carefully.
