Cheese and Onion Puff Pastry Tart Recipe

Cheese and onions form a delicious marriage of flavors in a tart recipe that is surprisingly sweet from the sugars in the onions. This one is really easy to put together --you can do the onions up ahead of time, and simply bake before serving-- and can be served in small bites for an appetizer, or larger slices for a first or second course.

This is one of those puff pastry appetizer recipes that looks like a lot more work than it actually is!

1 sheet puff pastry
3 tablespoons olive oil
2 sweet onions, thinly sliced
salt and pepper, to taste
6 ounces shredded Gruyère cheese
1/4 cup grated Parmesan cheese
2 tablespoons chives, chopped

Directions: 1. Preheat oven to 400°F. Line a baking sheet with parchment paper. Thaw pastry sheet at room temperature until pliable.

2. Over medium heat sauté onions in oil (add salt and pepper to taste) until golden brown and caramelized. Stir often. Season to taste with salt and pepper and set aside to cool.

3. Unfold pastry sheet on floured surface and roll to 12 inch square. Place dough on baking sheet. Brush edges with water and fold half an inch of each side over. Crimp edges with a fork to form a raised edge. Use fork to dock the middle of the tart. (Check puff pastry tips above for how to do this!)

4. Place onion mixture in middle of square and top with Gruyere, parmesan and chives. Bake 20 minutes and then cool on a wire rack. Cut into squares and serve warm. (Like most recipes using puff pastry sheets, this is also good at room temperature.)
