Cooking Time

Preparation: 20 minutes

Baking: 20 minutes
Total Time: 40 minutes

Ingredients

500 g (1 lb 2 oz) ready-rolled puff pastry

2 large eggs, separated
2 tablespoons milk
300 g (10 oz) spring onions (green onions), finely sliced

100 g (3 ½ oz) Parmesan cheese, grated
Salt, to taste
Freshly ground black pepper, to taste

1–2 tablespoons flour, for dusting
Optional garnish: extra Parmesan shavings or chopped chives

Step-by-Step Cooking Directions

Preheat the Oven: Preheat your oven to 200 °C (400 °F). Line a baking sheet with parchment paper and set aside.

Prepare the Pastry: Lightly dust your work surface with flour. Unfold the puff pastry sheet and roll it out gently to smooth any creases, maintaining roughly a 30 × 25 cm (12 × 10 inch) rectangle. Transfer the pastry to the prepared baking sheet.
Dock and Border: Using a fork, prick (dock) the interior of the pastry, leaving a 2 cm (¾ inch) border around all sides un-docked. This will allow the center to puff less and create a neat edge.
Sauté the Spring Onions: In a skillet over medium heat, add a splash of oil or cooking spray. Sauté the sliced spring onions for 3–4 minutes until they soften but remain bright green. Season lightly with salt and pepper. Remove from heat and let cool slightly.

Mix the Filling: In a medium bowl, whisk together the two egg yolks (reserve the whites), milk, and a pinch of salt and pepper. Stir in the sautéed spring onions and grated Parmesan until evenly combined.
Assemble the Tart: Spoon the filling mixture onto the docked pastry, spreading it evenly within the border. Be careful not to overfill.
Egg Wash: In a small bowl, whisk the two reserved egg whites with a teaspoon of water. Brush the exposed pastry border with this egg white wash to achieve a glossy, golden crust.

Bake: Place the tart in the preheated oven and bake for 18–20 minutes, or until the pastry has risen, the edges are golden brown, and the filling is set.
Rest and Serve: Remove the tart from the oven and allow it to rest for 5 minutes. Garnish with extra Parmesan shavings or chopped chives if desired. Slice into squares or wedges and serve warm or at room temperature.

The Origins and Popularity of the Recipe

Puff pastry tarts featuring seasonal vegetables have roots in French cuisine, where pâte feuilletée (puff pastry) is a cornerstone. Similar savory “tarte fine” preparations became popular in bistros across Europe, showcasing simple, high-quality ingredients. The combination of spring onions and cheese evokes classic quiches of Lorraine and Alsace, yet this tart’s streamlined assembly appeals to modern home cooks seeking minimal effort. With the resurgence of rustic, vegetable-focused dishes on social media and food blogs, this tart has gained momentum as a visually appealing, customizable recipe that bridges casual home cooking and elegant entertaining.

Reasons Why You’ll Love the Recipe

Effortless Elegance: Achieve a café-style tart with minimal ingredients and prep.

Seasonal Flavor: Showcases the bright, mild taste of fresh spring onions.
Make-Ahead Friendly: Assemble in advance and refrigerate; bake just before serving.
Versatility: Enjoy it hot, warm, or cold as a starter, main, or snack.

Health Benefits

Spring onions are rich in vitamins A and C, supporting immune function and skin health. They also contain antioxidants and sulfur compounds linked to heart health. Parmesan cheese provides protein and calcium for bone strength, while puff pastry—though indulgent—delivers energy and satisfaction. By balancing vegetables with moderate cheese and pastry, this dish fits into a varied, nutrient-aware diet when paired with a green salad or fresh fruit.

Serving Suggestions

With Salad: Pair alongside a crisp mixed-greens salad tossed in lemon vinaigrette.
As Brunch: Serve with smoked salmon, avocado slices, and poached eggs.
Light Lunch: Offer with a bowl of chilled tomato soup or gazpacho.

Party Platter: Surround with cured meats, olives, and pickles for a rustic antipasto spread.

Common Mistakes to Avoid

Over-docking: Too many fork pricks can cause dryness; dock only the center.
Wet Filling: Ensure sautéed onions are cool and not oily, or the pastry will become soggy.

Skipping Egg Wash: Without it, the border won’t achieve a glossy, golden finish.
Underbaking: Watch the edges—pastry should be fully risen and crisp before removing.
Thick Pastry: Rolling pastry too thick yields undercooked centers; maintain uniform thickness.

Pairing Recommendations

Wines: A crisp Chardonnay or dry Rosé complements the richness of pastry and cheese.
Beers: Belgian witbier or Pilsner offers a refreshing contrast to savory flavors.
Non-Alcoholic: Sparkling mineral water with a twist of lime or a light herbal iced tea works beautifully.

Cooking Tips

Chill the Pastry: If at room temperature, pop the pastry in the fridge for 10 minutes to firm up before baking.
Even Sauté: Cook onions gently to preserve their color and mild sweetness.
Cheese Alternatives: Swap Parmesan for Gruyère, aged cheddar, or a blend for varied flavor.

Uniform Slicing: Slice spring onions evenly to ensure consistent texture.
Monitor Heat: Bake on the middle rack for balanced heat and avoid burning.

Frequently Asked Questions

Can I use homemade puff pastry?
Yes. Roll homemade dough to the same thickness and follow the same docking and baking times.
How do I prevent a soggy crust?
Ensure the sautéed spring onions are well-drained and cooled before mixing into eggs.

Can I bake at a lower temperature?
You can bake at 180 °C (350 °F) for 22–25 minutes, but watch for puff and color.
Is the tart freezer-friendly?
Freeze fully baked and cooled, wrapped tightly, for up to 1 month. Reheat in a 180 °C oven.
What’s the best way to reheat slices?
