Ingredients You’ll Need
This recipe relies on a handful of ingredients that work harmoniously to build layers of flavor and texture — each one playing a crucial role. From the buttery puff pastry delivering flaky crunch to the creamy Camembert adding a mellow depth, these ingredients are both accessible and essential.
- Puff Pastry Sheet (14 ounces): Use high-quality puff pastry like Dufour for the best flaky and buttery crust that will hold all the toppings beautifully.
- Camembert (8 ounces): Thinly sliced for perfect melting and that signature creamy, earthy bite that ties everything together.
- Olive Oil (1 tablespoon): Adds a subtle richness and helps gently sauté the vegetables without overpowering their flavor.
- Garlic (3 cloves, minced): Boosts the savory depth, infusing warmth and aroma in every bite.
- Red Onion (1, thinly sliced): Offers sweetness and a bit of tangy sharpness that softens once cooked.
- Leeks (2, halved and thinly sliced, white and light green parts): Delivers mild, sweet onion flavor with a tender texture that complements the Camembert.
- Kosher Salt (1 teaspoon): Enhances all the flavors without tasting salty.
- Freshly Ground Pepper (to taste): Adds a gentle kick and rounds out the flavor profile.
How to Make Leek, Onion, and Camembert Puff Pastry Tart Recipe
Step 1: Preheat and Prepare
Start by heating your oven to a cozy 400 degrees Fahrenheit (200 degrees Celsius). This temperature is perfect for ensuring your puff pastry puffs up with golden crispiness while cooking the toppings just right. Having the oven ready to go will make the final assembly smooth and stress-free.
Step 2: Sauté the Aromatics
Warm a tablespoon of olive oil in a frying pan over medium heat. Toss in the minced garlic and sliced red onion. Cooking these for about 3 minutes softens the onion and lets the garlic release its fragrant oils, laying an aromatic foundation for the tart.
Step 3: Add the Leeks
Now, stir in the sliced leeks along with a teaspoon of kosher salt. Cook for about 5 more minutes while stirring often. This step tenderizes the leeks and onions, bringing out their natural sweetness and melding their flavors beautifully. The salt helps draw out moisture, so your tart will stay crisp rather than soggy.
Step 4: Prepare the Puff Pastry
Lay your puff pastry sheet on a baking tray lined with parchment paper. Trim the edges for neatness, then cut a ½ inch border all around. Prick the center area of the pastry with a fork several times — this ensures the middle doesn’t puff up too much while baking, keeping a perfect base for your luscious toppings.
Step 5: Assemble the Tart
Evenly distribute the thin slices of Camembert across the pricked center section of the puff pastry. The cheese will melt into rich, gooey pockets. Next, pile the cooked leeks and onions on top, spreading them carefully to cover the cheese. This layering is where all the magic happens.
Step 6: Bake to Perfection
Pop the tart into the preheated oven and bake for 15 to 20 minutes, or until the crust turns a beautiful golden brown and you can see the cheese bubbling slightly beneath the veggies. The aroma alone will have you ready to dig in!
Step 7: Rest and Serve
Once baked, let the tart cool for 2 to 5 minutes before slicing. This resting period lets the cheese settle just enough, so slices hold together and every bite is perfectly balanced.

Garnishes
To elevate your tart, sprinkle fresh thyme or finely chopped chives right before serving. These bright, herbaceous accents complement the creamy cheese magnificently and add a beautiful pop of green that invites your guests to dig in.
Side Dishes
This tart pairs wonderfully with a crisp green salad dressed lightly with lemon vinaigrette to cut through the richness. Roasted baby potatoes or a bowl of hearty soup can also round out the meal nicely if you’re serving it for lunch or dinner.
Creative Ways to Present
Feeling festive? Try serving individual tart squares atop small arugula nests on appetizer plates for a party. Or, add slices of ripe pear or fig alongside to introduce a sweet contrast. Whether casual or fancy, this tart adapts beautifully to your style.
Make Ahead and Storage
Storing Leftovers
Keep any leftover tart covered in the refrigerator for up to 2 days. Make sure to store it tightly wrapped or in an airtight container to preserve the puff pastry’s texture and prevent the leeks from drying out.
Freezing
This tart doesn’t freeze well once assembled and baked because puff pastry loses its crispness easily when thawed. However, you can freeze the cooked leek and onion mixture separately for up to 3 months and prepare the tart fresh whenever you want.
Reheating
To reheat leftovers, place slices on a baking sheet and warm in a 350-degree oven for about 10 minutes. This method crisps the pastry again without overcooking the toppings, bringing your tart back to near-fresh glory.
FAQs
Can I use another cheese instead of Camembert?
Absolutely! Brie is a great substitute since it melts similarly and has a compatible flavor. Just be sure to slice it thinly to encourage even melting.
Do I need to thaw puff pastry before using it?
Yes, letting puff pastry thaw according to package instructions ensures it’s pliable enough to work with but still cold enough to puff up nicely when baked.
Can I make this tart vegan?
To make a vegan version, swap Camembert for a plant-based cheese that melts well, and use olive oil or a vegan butter alternative for cooking. The flavor profile will differ but can still be delicious.
Is it possible to add other vegetables?
Definitely! Sautéed mushrooms, spinach, or even roasted peppers can complement the leeks and onions beautifully. Just adjust cooking times to avoid adding too much moisture.
How do I know when the tart is fully baked?
You’ll want to see a golden-brown crust with bubbling cheese peeking out from underneath the vegetables. The edges should be crisp and slightly puffed, signaling that it’s ready to come out of the oven.
