How to Make Garlic Herb Mushroom Tart

This elegant tart is easier than it looks. Follow these simple steps for a perfectly golden, flaky, and flavorful dish.

Step 1: Prepare the Puff Pastry

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

On a lightly floured surface, gently roll out the thawed puff pastry sheet to smooth out the creases. Transfer the pastry to the prepared baking sheet .

Using a sharp knife, score a 1/2-inch border around the edges of the pastry. Do not cut all the way through—this creates a raised edge that will puff up and contain the toppings. Prick the inside area with a fork to prevent it from puffing up too much .

Step 2: Cook the Mushrooms

Heat the olive oil or butter in a large skillet over medium heat. Add the chopped onion and cook until soft and translucent, about 5 minutes. Add the minced garlic and cook for another minute until fragrant .

Add the sliced mushrooms and cook, stirring occasionally, for 8-10 minutes, until they release their liquid and it evaporates. The mushrooms should be golden brown and tender . Season with salt, pepper, and fresh thyme. Remove from heat and stir in the fresh parsley. Let the mixture cool slightly .

Step 3: Assemble the Tart

In a small bowl, mix the cream cheese and Parmesan cheese together until smooth. Spread this cheese mixture evenly over the center of the puff pastry, staying within the scored border .

Spoon the sautéed mushroom mixture evenly over the cheese layer .

Step 4: Egg Wash and Bake

In a small bowl, whisk the egg with the milk or water. Brush the raised border of the pastry with the egg wash. This will give it a beautiful golden, glossy finish when baked .

Bake for 18-20 minutes, or until the pastry is puffed up and golden brown .

Step 5: Garnish and Serve

Let the tart cool on the baking sheet for 5 minutes. Garnish with a sprinkle of fresh thyme leaves or parsley .

Slice and serve warm or at room temperature. This tart is delicious on its own or with a simple green salad .

Tips for a Perfect Mushroom Tart

Don’t crowd the pan: Sauté mushrooms in a single layer to ensure they brown, not steam. If needed, cook them in batches .

Keep the pastry cold: If your puff pastry starts to warm up and soften while you’re assembling the tart, pop it back in the fridge for 10 minutes before baking to ensure the best puff and flakiness .

Pat mushrooms dry: Before slicing, gently wipe mushrooms clean with a damp paper towel. Excess moisture will make the pastry soggy .

Score, don’t cut: When creating the border, make sure you only score the pastry. Cutting all the way through will prevent the edges from puffing up properly .

Delicious Variations to Try

• Spinach and Mushroom Tart: Add a few handfuls of fresh spinach to the skillet with the mushrooms and cook until wilted .
• Gruyère Mushroom Tart: Sprinkle grated Gruyère cheese over the mushrooms before baking for a nutty, melty topping .
• Wild Mushroom and Walnut Tart: Add toasted, chopped walnuts to the mushroom mixture for extra texture and a rich, earthy flavor .
• Goat Cheese Mushroom Tart: Swap the cream cheese for crumbled goat cheese for a tangier flavor .

How to Store and Reheat

Storing: Baked tart can be stored in an airtight container in the refrigerator for up to 3 days .

Reheating: To re-crisp the pastry, reheat slices in a 350°F oven for 5-7 minutes. The microwave will make the pastry soft, so it’s best to avoid it.

Freezing: It is not recommended to freeze this tart, as the mushrooms can release moisture upon thawing.
