Wow, this was really good, and you just use all-butter puff pastry for the crust, so it is not as difficult as it looks.
I got this recipe from the New York Times, and offer it here only slightly modified.
Asparagus Goat Cheese Tart Recipe
4 ounces soft goat cheese, at room temperature
1 large egg, lightly beaten, at room temperature
1 large garlic clove, finely grated or minced
1½ Tablespoons chopped fresh tarragon leaves, plus more for serving
½ Tablespoon finely grated lemon zest
½ teaspoon fine sea salt, plus more for sprinkling
Pinch of freshly grated nutmeg
1 cup crème fraîche, at room temperature (8 ounces)
All-purpose flour, for dusting the work surface
1 sheet or square all-butter puff pastry, thawed if frozen (about 9 to 14 ounces; brands vary)
8 ounces thin asparagus, woody ends trimmed
Extra-virgin olive oil
2 Tablespoons grated Parmesan
Freshly ground black pepper
Red-pepper flakes (optional)
1½ ounces Parmesan, shaved with a vegetable peeler (about ½ cup)
Heat oven to 425 degrees.
In a medium bowl, use a fork or a wooden spoon to mash together the goat cheese, egg, garlic, tarragon, lemon zest, salt and nutmeg until smooth. Switch to a whisk and beat in the crème fraîche until smooth.
On a lightly floured surface, roll out puff pastry into a 13-by-11-inch rectangle about ⅛-inch thick. Transfer the dough to a parchment-lined cookie sheet. With a sharp knife, lightly score a ½-inch border around the edges of the puff pastry.
Spread the crème fraîche mixture evenly inside the scored border. Line up the asparagus spears on top, and brush them with olive oil. Sprinkle some salt and the grated Parmesan over the asparagus.
Bake until the pastry is puffed and golden, 25 to 30 minutes. Let it cool on the cookie sheet for at least 15 minutes or up to 4 hours before serving. Then sprinkle black pepper, red-pepper flakes (if using), the shaved Parmesan and tarragon leaves. Drizzle a little oil on top.
