How to Make Simple Mushroom Tarts Recipe | Tastylicious!
- Preheat your oven to 400°F and line a baking sheet with parchment paper.
- In a large skillet, heat butter and olive oil over medium heat. Add minced shallot and garlic, sautéing until fragrant and translucent, about 2 minutes.
- Add chopped mushrooms, thyme, salt, and pepper. Cook, stirring occasionally, until mushrooms release their moisture and it evaporates, about 8-10 minutes. Remove from heat and stir in grated Parmesan. Let cool slightly.
- Roll out the thawed puff pastry on a lightly floured surface. Cut into 8 equal squares and place them on the prepared baking sheet.
- Divide the mushroom mixture evenly among the pastry squares, leaving a small border. Fold the edges slightly inward to create a rim.
- Brush the pastry edges with beaten egg to achieve a golden finish.
- Bake for 15-18 minutes or until the pastry is puffed and golden brown.
- Remove from oven and allow tarts to cool for 5 minutes before serving. Garnish with extra thyme if desired.
Tips for the Best Results
- Make sure to cook the mushrooms until all moisture evaporates to avoid soggy pastry.
- Use fresh thyme for a brighter, more aromatic flavor.
- Keep the puff pastry cold until just before baking to ensure maximum flakiness.
- For added richness, sprinkle a little shredded Gruyère or fontina cheese on top before baking.
- Serve warm for the best texture and flavor experience.
Storage and Reheating
Store any leftover simple mushroom tarts in an airtight container in the refrigerator for up to 3 days. To maintain crispness, reheat them in a preheated 350°F oven for about 8-10 minutes rather than using a microwave.
For longer storage, freeze the baked tarts on a tray until solid, then transfer to a freezer-safe container for up to 1 month. Reheat directly from frozen in a 375°F oven for 12-15 minutes until hot and crispy.
Frequently Asked Questions
Can I use other types of mushrooms?
Absolutely! You can use button, shiitake, or a mix of wild mushrooms for different flavors and textures. Just be sure to finely chop them and cook out the moisture.
Is puff pastry necessary for this recipe?
Puff pastry gives these tarts their signature flaky texture, but you could substitute with phyllo dough or shortcrust pastry if preferred, though the texture will differ.
Can I make the mushroom filling ahead of time?
Yes, you can prepare the mushroom filling a day in advance and store it in the fridge. Bring it to room temperature before assembling the tarts.
Are these tarts vegetarian?
Yes, this recipe is vegetarian-friendly. To make it vegan, omit the Parmesan and use vegan butter and an egg substitute for the wash.
