Mini savory tart with wild mushrooms and caramelized leeks, filled with golden custard, topped with thyme and served on ceramic plate in natural light.

There’s something timeless about a dish that feels both refined and rustic. The crackle of golden pastry, the depth of wild mushrooms, and the gentle sweetness of caramelized leeks come together in a way that feels more like a story than a recipe. This mini savory tart is built on contrasts: crisp and soft, earthy and sweet, elegant yet familiar.

I first made these in early autumn, when the markets were full of chanterelles, creminis, and shiitakes—each with its own character. The scent of them roasting, mingling with shallots and thyme, was grounding. Paired with gently caramelized leeks and encased in a buttery tart shell, this recipe became a quiet ritual: a centerpiece for intimate dinners or an elevated bite for gatherings. These mini savory tarts don’t ask for extravagance. They ask for care—and they give comfort in return.


Ingredients You Will Need

Balance is everything here. These ingredients shine when handled with intention, creating a tart that’s visually striking and deeply satisfying.

🍄 For the Filling:

  • 2 tablespoons olive oil
  • 1 small shallot, finely diced
  • 2 cups wild mushrooms, cleaned and chopped
  • 2 teaspoons fresh thyme leaves
  • ½ teaspoon kosher salt
  • ¼ teaspoon freshly ground black pepper


🧅 For the Caramelized Leeks:

  • 2 tablespoons unsalted butter
  • 2 leeks, white and light green parts only, thinly sliced
  • ½ teaspoon sea salt
  • 1 teaspoon sugar
  • 1 tablespoon water


🧀 For the Custard Base:

  • 2 large eggs
  • ⅓ cup heavy cream
  • ¼ cup grated Gruyère cheese
  • Pinch of nutmeg


🥧 For the Tart Assembly:

  • 6 savory tart shells, pre-baked
  • Fresh thyme, for garnish
  • Cracked black pepper, to finish

💡 Pro Tip: Pre-made savory tart shells offer convenience, but if you have the time, blind baking your own dough with butter and thyme adds extra depth.


Step 1: Sautéing the Wild Mushroom Filling

Ingredients Used:

✔ Olive oil, shallot, wild mushrooms, thyme, salt, pepper

Method:

1️⃣ Warm the Base:

Heat olive oil in a skillet over medium heat. Add shallot and cook until translucent, about 2 minutes.

2️⃣ Sauté the Mushrooms:

Add the wild mushrooms and thyme. Let them cook undisturbed for 3–4 minutes to develop color. Stir, season with salt and pepper, and cook until golden and reduced, about 6 more minutes.

3️⃣ Rest and Cool:

Transfer the mixture to a bowl to cool slightly before assembly.

💡 Chef’s Note: Don't overcrowd the pan. Cook mushrooms in batches if needed to avoid steaming.


Step 2: Caramelizing the Leeks

Ingredients Used:

✔ Butter, leeks, sea salt, sugar, water

Method:

1️⃣ Melt and Simmer:

In a separate pan, melt butter over medium-low heat. Add leeks, salt, and sugar. Cook gently, stirring often, for 10–12 minutes.

2️⃣ Finish Softly:

Add a splash of water and let simmer another 2 minutes until leeks are soft and golden.

3️⃣ Cool to Use:

Set aside and let cool slightly before layering into the tart shells.

💡 Pro Tip: Stir frequently and don’t rush—slow caramelization brings out the leeks' delicate sweetness.


Step 3: Preparing the Custard and Assembling the Tarts

Ingredients Used:

✔ Eggs, cream, Gruyère, nutmeg, tart shells

Method:

1️⃣ Make the Custard:

Whisk eggs, cream, Gruyère, and nutmeg until fully combined. Let sit for 5 minutes to settle air bubbles.

2️⃣ Assemble the Mini Tarts:

Place a spoonful of the mushroom mixture and caramelized leeks into each savory tart shell. Pour custard over the filling, just below the rim.

3️⃣ Bake Until Set:

Bake in a preheated 350°F (175°C) oven for 18–20 minutes or until the custard is set and lightly golden on top.

4️⃣ Cool Slightly:

Let the mini savory tarts cool for 10 minutes before garnishing with thyme and pepper.

💡 Presentation Tip: Serve on a neutral platter with linen napkins—elevate the rustic nature with clean styling.


Perfect Pairings Suggestions

🧀 Cheese: A sliver of aged Comté brings nutty complexity that matches the richness of the tart.

🌿 Infused Oil: A few drops of walnut oil on the plate or atop the tart add an earthy, aromatic finish.

🍋 Dessert: End with a lemon posset or citrus panna cotta to cleanse the palate with bright acidity.
