Ingredients

• 2 sheets frozen puff pastry, thawed
• 2 tablespoons olive oil or butter
• 1 shallot, finely chopped
• 3 cloves garlic, minced
• 12 oz (340g) mixed mushrooms, finely chopped
• 1 teaspoon fresh thyme leaves (plus extra for garnish)
• 1 tablespoon Dijon mustard (optional)
• Salt and black pepper to taste
• 8 oz (225g) Brie cheese, rind removed and cubed
• 1 egg, beaten (for egg wash)
• Fresh parsley or thyme for garnish

Instructions

1. Preheat and Prep: Start by preheating your oven to 400°F (200°C). Lightly grease two mini muffin tins or line a baking sheet with parchment paper. This ensures your tartlets release easily and bake evenly to golden perfection.
2. Cut the Pastry: Roll out the thawed puff pastry slightly on a lightly floured surface. Using a 2.5-inch round cutter, cut out 24 circles. Gently press each circle into the muffin cups, creating little pastry shells. Prick the bottoms with a fork to prevent puffing too much.
3. Sauté the Aromatics: Heat olive oil or butter in a large skillet over medium heat. Add the chopped shallot and cook for 2-3 minutes until softened and fragrant, building a sweet base for your filling.
4. Cook the Mushrooms: Increase heat to medium-high and add the chopped mushrooms. Sauté for 6-8 minutes, stirring occasionally, until they release their liquid and turn beautifully golden brown. This step concentrates all that wonderful umami flavor.
5. Season Beautifully: Stir in minced garlic and fresh thyme. Cook for another minute until fragrant. Add a touch of Dijon if using, then season generously with salt and pepper. Remove from heat and let the mixture cool slightly.
6. Fill with Love: Spoon about a teaspoon of the mushroom mixture into each pastry shell. Top each with a small cube of Brie cheese, tucking it gently so it melts into the mushrooms during baking.
7. Egg Wash Magic: Brush the exposed edges of the pastry with beaten egg. This gives your tartlets a gorgeous glossy, golden finish that makes them look bakery-worthy.
8. Bake to Perfection: Place in the preheated oven and bake for 15-20 minutes, or until the pastry is puffed and deep golden and the cheese is melted and bubbly. Rotate the pans halfway through for even browning.
9. Cool Slightly: Remove from the oven and let the tartlets cool in the pan for about 5 minutes. This helps the filling set so they hold together beautifully when removed.
10. Garnish and Serve: Carefully transfer to a serving platter. Sprinkle with fresh thyme leaves or chopped parsley for a pop of color and freshness. Serve warm and watch them disappear!

Notes

These tartlets are best enjoyed warm when the Brie is perfectly gooey. Pair with a crisp white wine or sparkling rosé. They’re naturally elegant yet approachable—great for beginners and seasoned cooks alike. For a make-ahead party win, assemble ahead and bake just before guests arrive.

Recipe Tips and Tricks

• Use cold puff pastry straight from the fridge for the flakiest shells.
• Sauté mushrooms on high heat to evaporate moisture quickly and achieve deep golden color.
• Don’t overfill the tartlets—leave a little room for the cheese to melt and bubble.
• For extra shine, brush the pastry edges with egg wash before baking.
• Let the tartlets cool for 5 minutes after baking so the filling sets slightly.
• Make the mushroom filling up to a day ahead and refrigerate to save time.

Ingredients Notes

High-quality puff pastry is key—it creates those beautiful, airy layers that cradle the filling perfectly. Fresh mushrooms (a mix of cremini, button, and shiitake works wonderfully) bring earthy depth and meaty texture; avoid pre-sliced ones as they tend to be drier.

Brie cheese provides creamy richness—choose a triple-cream variety for extra indulgence, but any soft-ripened Brie will melt beautifully. Fresh thyme adds bright herbal notes that elevate the dish; dried can work in a pinch but use half the amount.

Garlic brings aromatic punch, while shallots offer subtle sweetness. A touch of Dijon mustard or balsamic adds complexity without overpowering. Season generously with salt and pepper to balance the richness.

Variations and Substitutions

Make it your own by swapping mushrooms for wild varieties like oyster or chanterelle when in season for deeper forest flavors. For a meaty twist, add crumbled cooked bacon or prosciutto.

Spinach or kale can be stirred in for a green boost. If you prefer milder cheese, substitute Camembert or goat cheese. For a gluten-free version, use gluten-free puff pastry. Add a sprinkle of chopped walnuts or pecans for crunch.

Turn up the heat with red pepper flakes or a dash of truffle oil for luxury. For mini versions, use smaller pastry cups; for a larger tart, roll out one sheet and bake as a single galette. Vegetarian-friendly as written, it’s easy to adapt to vegan with plant-based cheese and pastry.

Storage Options

Store baked and cooled tartlets in an airtight container in the refrigerator for up to 3 days. Reheat in a 350°F (175°C) oven for 8-10 minutes until warmed through and pastry crisps up again.

For longer storage, freeze unbaked assembled tartlets on a tray until solid, then transfer to a freezer bag for up to 2 months. Bake directly from frozen, adding 5-7 extra minutes. Avoid microwaving as it softens the pastry.
