This mushroom leek tart is a delightful combination of earthy mushrooms and sweet leeks, all encased in a buttery puff pastry. It's perfect for a brunch, lunch, or even a light dinner. The creamy egg mixture and the nutty gruyere cheese add a rich flavor that complements the vegetables beautifully.
If you don't usually cook with leeks, they are a member of the onion family and have a mild, sweet flavor. Make sure to clean them thoroughly as they can hold a lot of dirt between their layers. Gruyere cheese is a type of Swiss cheese known for its creamy and nutty taste. If you can't find it, you can substitute it with another type of Swiss cheese or even cheddar.
Ingredients for Mushroom Leek Tart
Puff pastry: A light, flaky pastry that serves as the base for the tart.
Olive oil: Used to sauté the vegetables, adding a rich flavor.
Leeks: A mild, sweet member of the onion family that pairs well with mushrooms.
Mushrooms: Earthy and savory, they add depth to the tart.
Heavy cream: Adds richness and creaminess to the egg mixture.
Eggs: Helps to set the tart and adds protein.
Gruyere cheese: A nutty, creamy cheese that melts beautifully.

Technique Tip for This Tart
When preparing the leeks, make sure to clean them thoroughly. Leeks can often have dirt and grit trapped between their layers. Slice them lengthwise and rinse under cold water, separating the layers to ensure all debris is removed. This will prevent any unwanted texture in your mushroom leek tart.

How to Store or Freeze This Tart
Allow the mushroom leek tart to cool completely before storing. This helps to prevent condensation, which can make the puff pastry soggy.
Wrap the tart tightly in plastic wrap or aluminum foil. Ensure that it is well-sealed to maintain freshness and prevent any odors from the fridge from seeping in.
Store the wrapped tart in an airtight container to provide an extra layer of protection. This is especially useful if you plan to keep it in the fridge for more than a day.
For short-term storage, place the tart in the refrigerator. It will stay fresh for up to 3 days. When ready to eat, reheat in a preheated oven at 350°F (175°C) for about 10-15 minutes, or until warmed through.
For longer storage, consider freezing the tart. First, place the cooled tart on a baking sheet and freeze until solid. This prevents the tart from sticking to the wrapping.
Once frozen, wrap the tart in plastic wrap followed by a layer of aluminum foil. This double wrapping helps to protect against freezer burn and preserves the tart's flavor and texture.
Label the wrapped tart with the date of freezing. This helps you keep track of how long it has been stored. The tart can be frozen for up to 2 months.
When ready to enjoy, thaw the tart in the refrigerator overnight. Reheat in a preheated oven at 350°F (175°C) for about 20-25 minutes, or until heated through and the puff pastry is crisp.
If you prefer individual servings, slice the tart before freezing. Wrap each slice individually in plastic wrap and aluminum foil, then place them in a single layer in an airtight container or a freezer bag. This allows you to thaw and reheat only what you need.
To reheat individual slices, place them on a baking sheet and warm in a preheated oven at 350°F (175°C) for about 10-15 minutes, or until heated through and the puff pastry is crisp.
How to Reheat Leftovers
Preheat your oven to 350°F (175°C). Place the leftover mushroom leek tart on a baking sheet and cover it loosely with aluminum foil. Heat for about 15-20 minutes, or until warmed through. This method helps maintain the tart's crispiness and avoids sogginess.
For a quicker option, use a toaster oven. Set it to 350°F (175°C) and place the tart inside for about 10-15 minutes. Keep an eye on it to ensure it doesn't overheat or burn.
If you're in a hurry, the microwave can be used, though it may make the puff pastry a bit soft. Place a slice of the tart on a microwave-safe plate and cover it with a damp paper towel. Heat on medium power for 1-2 minutes, checking halfway through to ensure even heating.
For an air fryer, preheat it to 320°F (160°C). Place the tart inside and heat for about 5-7 minutes. This method can help retain some of the tart's original texture and crispiness.
If you prefer stovetop reheating, use a skillet over medium-low heat. Place the tart slice in the skillet and cover with a lid. Heat for about 5-7 minutes, flipping halfway through to ensure even warming. This method can help keep the puff pastry somewhat crispy.
