Ingredients

• 1 sheet puff pastry, about 9-10 oz, defrosted but kept cool in the refrigerator

• 2 tablespoons Dijon mustard (optional)

• 1 bunch fresh asparagus (about 8 oz), trimmed

• 3 cups (12 oz) shredded Gruyère cheese

• ½ cup (1.5 oz) shredded Parmesan cheese

• 1 large egg (for egg wash)

• Freshly ground black pepper and tarragon leaves for garnish

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

Directions

1. Preheat the oven to 400℉ (200℃). Line a baking sheet with parchment paper.

2. On a lightly floured surface, roll the puff pastry into an 11×14-inch rectangle. Trim the edges to create a straight line if necessary. Transfer the dough to the prepared baking sheet.

3. Score the dough around the edges with a sharp knife to create a 1-inch border (don’t cut all the way through). Prick the dough with a fork within the border.

4. Spread Dijon mustard evenly over the center of the pastry, leaving the border free.

5. Sprinkle the shredded Gruyère cheese over the mustard, and arrange the asparagus spears on top, parallel to each other.

6. Sprinkle Parmesan cheese over the top of the asparagus and cheese.

7. For the egg wash, whisk together the egg with 1 tablespoon of water and brush the edges of the dough with the mixture.

8. Bake for 20 to 25 minutes, or until the pastry is golden and puffed, and the cheese is melted.

9. Remove from the oven and cool slightly. Garnish with freshly ground black pepper and tarragon leaves before serving.

FAQs

Can I use a different type of pastry for this tart?

Yes, you can use a shortcrust pastry or a phyllo dough if you prefer. However, puff pastry gives the tart its signature light and flaky texture.

How do I know when the tart is done?

The tart is done when the edges of the pastry are golden brown and the cheese is melted and bubbling. The crust should be crisp and flaky.

Can I use pre-shredded cheese?

For the best texture and flavor, it’s recommended to shred the cheese yourself. Pre-shredded cheese contains anti-caking agents that can prevent smooth melting.

Is this tart gluten-free?

No, this tart contains puff pastry, which is made from wheat flour. To make it gluten-free, you’d need to find a gluten-free puff pastry.

Can I make this ahead of time?

Yes, you can prepare the tart ahead of time by assembling it and storing it in the refrigerator for up to 24 hours before baking.

What can I serve with this tart?

This tart pairs beautifully with a light salad or some roasted vegetables. It also makes a great side dish for a spring roast chicken.

What other vegetables can I use?

Can I freeze the tart before baking it?

Yes, you can freeze the assembled tart (before baking). Be sure to wrap it well and store it in the freezer for up to 1 month.

Can I add a protein to this tart?

Yes! Adding grilled chicken or other mild proteins would be a delicious addition.

How can I make the crust extra flaky?

To get the best results, make sure the puff pastry is cool when it goes into the oven. If it becomes too warm during assembly, refrigerate it for 15 minutes before baking.
