The Essential Ingredients for This Savory Tart
This recipe uses a handful of fresh, seasonal ingredients and one smart shortcut to create a truly spectacular result.
- The Puff Pastry Shortcut:
- Frozen Puff Pastry: This is the ultimate kitchen shortcut and the key to how easy this recipe is! A high-quality, all-butter frozen puff pastry will bake up into hundreds of light, airy, and shatteringly crisp layers. Be sure to thaw it according to the package directions.
- The Savory Mushroom Topping:
- Mushrooms & Shallots: The perfect pairing for a deep, savory, and umami-rich flavor. You can use classic cremini (baby bella) mushrooms, or a mix that includes shiitake or oyster mushrooms. Sweet, delicate shallots provide a more refined flavor than a regular onion.
- Fresh Herbs: It is highly recommended to use fresh thyme and rosemary. Their fragrant, woodsy aroma and flavor are far superior to dried herbs and are the key to a truly gourmet-tasting tart.
- Balsamic Vinegar: A final splash of balsamic vinegar into the cooked mushroom mixture adds a wonderful, bright, tangy, and slightly sweet note that beautifully balances all the rich, earthy flavors.
- The Cheese:
- Gorgonzola Cheese: This is a type of Italian blue cheese with a wonderfully sharp, tangy, and pungent flavor. Its bold taste is a perfect, classic pairing for the earthy mushrooms and the rich, buttery pastry.
Step-by-Step to the Perfect Puff Pastry Tarts
Follow these simple, detailed steps for a perfect, golden-brown, and puffy result every time.
Step 1: Cook the Savory Mushroom Topping
Step 1: In a large skillet over medium heat, cook the 3 tablespoons of unsalted butter and the 3/4 cup of sliced shallots, stirring often, for about 3 minutes, until the shallots begin to soften.
Step 2: Add the 1 pound of sliced mushrooms, the 4 minced garlic cloves, the 1/2 teaspoon of salt, the 1/4 teaspoon of pepper, the 2 teaspoons of fresh thyme, and the 2 teaspoons of fresh rosemary to the skillet.
Step 3: Stir and cook for another 5 to 6 minutes, until the mushrooms are soft, have released their liquid, and that liquid has cooked off.
Step 4: Remove the skillet from the heat and stir in the 1 tablespoon of balsamic vinegar. Set the topping aside to cool slightly while you prepare the pastry.
Pro Tip: Cooking the mushrooms first is the secret to a perfectly crisp puff pastry tart! This crucial step removes their high water content, which prevents a soggy bottom.
Step 2: Prepare the Puff Pastry Bases
Step 1: Preheat your oven to 400°F (204°C). Line two large baking sheets with parchment paper.
Step 2: On a lightly floured work surface, roll your thawed puff pastry dough out into a large rectangle, about 10×17 inches in size and about 1/8-inch thick.
Step 3: Using a pizza cutter or a sharp knife, cut the large rectangle down the middle lengthwise to create two 5×17-inch rectangles. Then, cut across each of those rectangles to create a total of 10 smaller tarts, each about 3.5×5 inches in size.
Step 4: In a small bowl, prepare your egg wash by beating the 1 egg with 1 tablespoon of water or milk. Brush the egg wash all over the surface of each of the puff pastry rectangles.
Step 5: Use the tines of a fork to crimp a decorative edge all the way around each rectangle.
Step 6: Carefully transfer the prepared pastry rectangles to your lined baking sheets, placing 5 tarts on each sheet.
Step 3: Assemble and Bake Your Beautiful Tarts
Step 1: Sprinkle each of the pastry rectangles with about 1.5 tablespoons of the crumbled gorgonzola cheese, leaving the crimped edge clear.
Pro Tip: Placing the cheese under the mushrooms is a clever trick! It creates a delicious, savory barrier that further helps to protect the pastry from any moisture from the topping, ensuring an extra-crisp result.
Step 2: Spoon the cooked mushroom topping (about a scant 1/4 cup for each tart) over the top of the cheese. Use the back of a spoon to lightly press the topping down so that it adheres to the cheese.
Step 3: Bake the tarts for 20 to 22 minutes, or until the pastry is a deep, beautiful golden brown all over and is wonderfully puffed up.
Remove the tarts from the oven. If you desire, you can garnish them with a sprinkle of flaky sea salt, more fresh herbs, a little extra cheese, and/or a drizzle of a thick balsamic glaze. Serve them warm or at room temperature.

Notes
- This recipe works well with either homemade or store-bought puff pastry for convenience.
- Pre-cooking the mushroom topping on the stovetop ensures the vegetables are tender and flavorful in the finished tart, and prevents the pastry from becoming soggy.
- Leftovers can be stored in the refrigerator for up to 5 days and reheated in the oven.
Storage and Make-Ahead Tips
These savory tarts are at their absolute crispiest and best on the day they are made, preferably served warm from the oven.
- Make-Ahead: For a super-fast, fresh-from-the-oven treat, you can prepare the cooked mushroom topping up to 3 days in advance. Let it cool completely and store it in an airtight container in the refrigerator. When you are ready to serve, simply assemble the tarts on the fresh puff pastry and bake as directed.
- Storage: If you do have leftovers, they can be stored in an airtight container in the refrigerator for up to 4 days.
- Reheating: The absolute best way to reheat the tarts and bring back some of their original crispiness is in an air fryer or back in a hot 375°F oven. Place them on a baking sheet and reheat for just 5-8 minutes, until they are hot and have crisped up again.

Creative Recipe Variations
- Use a Different Tangy Cheese: If you’re not a fan of blue cheese, this recipe is also absolutely fantastic with an equal amount of crumbled, tangy goat cheese or feta cheese.
- Add a Sweet and Savory Drizzle: For a beautiful, glossy finish and an extra layer of flavor, you can drizzle the finished, warm tarts with a little bit of hot honey or a high-quality, thick balsamic glaze.
- Add a Salty Meat Element: For a richer, heartier tart that could be a main course, you can sauté about 4 ounces of diced pancetta or prosciutto in the skillet first, remove it with a slotted spoon, and then cook your shallots and mushrooms in the rendered fat. Sprinkle the crispy pancetta back over the top of the tarts along with the final layer of cheese.

Frequently Asked Questions (FAQs)
Q1: What is the best way to thaw frozen puff pastry so it doesn’t break?
The absolute best way is to thaw it slowly in the refrigerator overnight. If you are short on time, you can let it sit at room temperature for about 40-60 minutes, but you must be careful. You want the dough to be just pliable enough to unfold without cracking, but it should still be very cold to the touch for the best, puffiest result.
Q2: How do I keep my puff pastry tart from getting a soggy bottom?
This recipe has two built-in secrets to prevent a soggy bottom! First, and most importantly, we pre-cook the mushroom topping on the stovetop. This crucial step removes the very high water content from the mushrooms before they ever go onto your delicate pastry. Second, we add a layer of cheese under the mushrooms, which acts as a delicious, protective barrier.
Q3: Can I make these tarts ahead of time for a party?
While you can, a puff pastry tart is at its absolute crispiest and best when it is served on the day it is baked. The best make-ahead method is to prepare the cooked mushroom topping in advance and store it in the refrigerator. Then, the assembly and baking will only take about 30 minutes on the day of your event.
Q4: What other vegetables can I use on a savory tart like this one?
This tart is incredibly versatile! You could swap the mushrooms and shallots for a variety of other delicious vegetables. Try it with thinly sliced zucchini and tomatoes (be sure to salt and drain them first!) in the summer, or caramelized onions and sliced potatoes in the winter. Just be sure to pre-cook them to remove their moisture first!
Q5: What is gorgonzola cheese, and is there a milder substitute?
Gorgonzola is a type of veined, Italian blue cheese. It has a wonderfully sharp, tangy, and pungent flavor that is a fantastic pairing with earthy mushrooms. If you are not a fan of blue cheese, a great, milder substitute would be a tangy, crumbled goat cheese or feta cheese, or a nutty, shredded cheese like Gruyère or fontina.
