Ingredients

• 1 Puff pastry sheet
• 2 cups Butternut squash
• 1.5 cups Parsnips
• 1.5 cups Carrots
• 1 cup Leeks
• 2 tablespoons Olive oil
• 1 teaspoon Fresh thyme leaves
• 0.5 teaspoon Salt
• 0.25 teaspoon Black pepper
• 0.5 cup Heavy cream
• 1 cup Gruyère cheese, shredded
• 0.5 cup Parmesan cheese, grated
• 1 Egg yolk
• 1 tablespoon Water

Directions

Step 1

Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.

Step 2

Peel and dice the butternut squash, parsnips, and carrots into 1/2-inch cubes. Thinly slice the leeks and rinse thoroughly to remove any grit.

Step 3

In a large bowl, toss the diced winter vegetables and leeks with olive oil, fresh thyme, salt, and black pepper.

Step 4

Spread the vegetable mixture evenly on a baking sheet and roast in the oven for 20 minutes, stirring halfway through, until tender and slightly caramelized. Remove and let cool slightly.

Step 5

Roll out the puff pastry sheet on a floured surface to a 12-inch square or circle. Transfer to a parchment-lined baking sheet.

Step 6

Spoon the roasted vegetable mixture onto the center of the puff pastry, leaving a 2-inch border around the edges. Drizzle the heavy cream evenly over the vegetables.

Step 7

Sprinkle the shredded Gruyère cheese and grated Parmesan cheese over the top of the vegetables for the gratin topping.

Step 8

Fold the puff pastry edges up over the filling, pleating as needed to create a rustic crust. The center of the croustade should remain exposed.

Step 9

In a small bowl, whisk together the egg yolk and water to create an egg wash. Brush the edges of the puff pastry with the egg wash for a golden finish.

Step 10

Bake the croustade in the preheated oven for 20 minutes, or until the pastry is puffed and golden brown and the cheese is bubbling and browned.

Step 11

Let the croustade cool slightly before slicing and serving warm. Enjoy!
