Peach Mascarpone Puff Pastry Tart

A golden, flaky tart layered with silky mascarpone cream and juicy summer peaches that looks like it came straight from a French patisserie.

There is something truly magical about pulling a puff pastry tart out of the oven when the edges have puffed up into golden, buttery layers and the peaches have softened into jammy, caramelized slices. The aroma alone fills your kitchen with the warm, sweet scent of ripe fruit and toasted pastry. This Peach Mascarpone Puff Pastry Tart is one of those desserts that looks incredibly impressive but comes together with very little effort, making it one of the most satisfying things you can bake on a warm afternoon.

This tart is perfect for summer entertaining, weekend brunches, or any occasion where you want to set something beautiful on the table without spending hours in the kitchen. Peak peach season runs from June through August, and this recipe is one of the best ways to celebrate those ripe, fragrant peaches before they disappear. Whether you are hosting a backyard gathering or just treating your family to something special on a weeknight, this tart delivers big flavor with minimal fuss.

I first made this tart on a whim one Sunday when I had a bag of perfectly ripe peaches sitting on the counter and a sheet of puff pastry in the freezer. I was not expecting much, but the first bite stopped me in my tracks. The combination of cool, lightly sweetened mascarpone cream against warm, caramelized peaches on that shatteringly crisp pastry base was so good I made it three more times that same month. Now it is one of my most requested recipes, and once you try it, you will completely understand why.

Ingredients

Pastry Base

1 sheet frozen puff pastry (about 9x9 inches), thawed

1 egg, beaten (for egg wash)

1 tablespoon granulated sugar (for sprinkling)

Mascarpone Cream

8 oz mascarpone cheese, at room temperature

1/3 cup powdered sugar, sifted

1 teaspoon pure vanilla extract

1/2 teaspoon lemon zest

2 tablespoons heavy cream

Peach Topping

3 medium ripe peaches, pitted and sliced 1/4 inch thick

2 tablespoons granulated sugar

1 teaspoon lemon juice

1/4 teaspoon cinnamon

1 tablespoon unsalted butter, cut into small pieces

Finishing Touches

2 tablespoons apricot jam or peach preserves

1 teaspoon water

Fresh thyme leaves or fresh mint for garnish (optional)

Powdered sugar for dusting (optional)

Substitutions & Variations

★If mascarpone is unavailable, you can substitute full-fat cream cheese blended with 2 tablespoons of heavy cream until smooth for a very similar texture and flavor.

★Nectarines work beautifully in place of peaches and require no peeling, so they are a great swap when peaches are not at peak ripeness.

★Frozen peaches can be used in a pinch; thaw them completely and pat them dry with paper towels before slicing to prevent excess moisture from making the pastry soggy.

★For a honey-flavored variation, replace the powdered sugar in the mascarpone cream with 2 tablespoons of good quality honey.

★If you prefer a different pastry shape, this recipe works just as well shaped into individual 4-inch rounds for single-serving tarts, reducing the baking time by about 5 minutes.

Step-by-Step Instructions

1

Thaw and Prep the Puff Pastry

Remove the puff pastry sheet from the freezer and let it thaw at room temperature for about 30 to 40 minutes, or thaw it overnight in the refrigerator. You want it pliable enough to unfold without cracking but still cold to the touch. Preheat your oven to 400 degrees Fahrenheit and line a large baking sheet with parchment paper.

2

Shape the Tart Shell

Unfold the thawed puff pastry sheet onto your prepared baking sheet. Using a sharp knife or a pizza cutter, score a border about 1 inch in from all four edges, being careful not to cut all the way through the pastry. This scored border will puff up and create the raised crust frame. Use a fork to prick the inner rectangle all over, about every half inch, to prevent it from puffing up too much during baking.

3

Apply the Egg Wash

Brush the scored border generously with the beaten egg using a pastry brush. Try to avoid getting egg wash on the cut score line, as this can glue the layers together and prevent the border from puffing properly. Sprinkle the border lightly with the tablespoon of granulated sugar for a golden, slightly sweet crust.

4

Blind Bake the Pastry

Slide the baking sheet into your preheated 400 degree oven and bake the pastry for 12 to 15 minutes, until the border is puffed and golden brown and the inner rectangle is set and lightly golden. If the center puffs up during baking, gently press it back down with the back of a spoon as soon as it comes out of the oven. Let the pastry cool completely on the baking sheet before adding any toppings, at least 20 minutes.

5

Prepare the Mascarpone Cream

While the pastry cools, combine the room temperature mascarpone, sifted powdered sugar, vanilla extract, lemon zest, and heavy cream in a medium bowl. Beat with a hand mixer on medium speed or stir vigorously with a rubber spatula until the mixture is smooth, creamy, and spreadable. Taste and adjust sweetness if needed. Cover and refrigerate until you are ready to assemble.

6

Season the Peaches

Slice the peaches into roughly 1/4-inch-thick wedges and place them in a bowl. Add the granulated sugar, lemon juice, and cinnamon, and toss gently to coat every slice. Let the peaches sit for about 5 minutes so they release a bit of their juice and the sugar begins to dissolve. This step brings out the natural sweetness of the fruit and adds a subtle warm spice note.

7

Arrange the Peaches

If you plan to serve this tart warm with baked peaches, arrange the seasoned peach slices in an overlapping shingled pattern over the inner rectangle of the cooled pastry. Dot the top with the small pieces of butter. Return the tart to the 400 degree oven for 8 to 10 minutes until the peaches are slightly softened and beginning to caramelize at the edges. Then remove and let cool for 10 minutes before adding the mascarpone.

8

Make the Apricot Glaze

While the peaches are baking, warm the apricot jam and water in a small saucepan over low heat, stirring until smooth and pourable, about 1 to 2 minutes. Alternatively, microwave for 20 seconds and stir well. This glaze gives the peaches a beautiful, glossy finish and adds a subtle fruity sweetness that ties everything together.

9

Spread the Mascarpone Cream

Once the pastry with baked peaches has cooled to just warm or room temperature, spread the chilled mascarpone cream evenly over the inner rectangle using an offset spatula or the back of a spoon. Go right up to the scored border but try not to cover it. The cool, creamy layer against the warm pastry is part of what makes this tart so irresistible.

10

Top with Peaches and Glaze

If you chose to bake the peaches directly on the pastry, they should already be resting on top of the mascarpone layer. If you prefer fresh peaches, simply arrange the seasoned raw slices over the mascarpone cream in overlapping rows now. Either way, brush the peach slices gently with the warm apricot glaze to give them a gorgeous, glossy sheen.

11

Garnish and Serve

Finish the tart with a light dusting of powdered sugar and a few fresh thyme leaves or mint sprigs if using. Thyme in particular adds a subtle herbal note that pairs beautifully with peaches. Slice into 8 pieces and serve immediately, or refrigerate for up to 2 hours before serving. The pastry stays crisp for a good hour after assembly, so do not wait too long before slicing.

Pro Baker Tips

✓Always keep your puff pastry cold right up until it goes into the oven; warm pastry loses its flakiness because the butter starts to melt before it can create steam layers.

✓Score the border with a light, confident cut rather than sawing back and forth, which can compress the layers and prevent a good puff.

✓If your peaches are very ripe and juicy, pat them dry with paper towels after macerating to prevent excess liquid from making the pastry soggy.

✓For the cleanest slices, use a sharp serrated knife and wipe the blade between cuts.

✓Room temperature mascarpone is essential; cold mascarpone can turn grainy when mixed, so pull it out of the fridge at least 30 minutes before you plan to use it.

✓This tart is best assembled close to serving time; you can bake the pastry shell and make the mascarpone cream several hours ahead, then assemble just before your guests arrive.

Storage & Serving Notes

◆Store leftover tart loosely covered in the refrigerator for up to 2 days; note that the pastry will soften overnight due to moisture from the mascarpone and fruit.

◆To partially restore crispness, place individual slices on a baking sheet and warm in a 325 degree oven for 5 to 7 minutes, then let cool slightly before eating.

◆The baked puff pastry shell can be made up to 8 hours ahead and stored at room temperature, uncovered, until ready to assemble.

◆The mascarpone cream can be made up to 24 hours in advance and stored in an airtight container in the refrigerator; give it a quick stir before spreading.

◆This tart is not ideal for freezing once assembled, as the mascarpone and peaches do not hold up well to freezing and thawing.

Frequently Asked Questions

Can I use canned peaches instead of fresh?

Yes, canned peaches work well when fresh are out of season. Choose peaches packed in juice rather than heavy syrup, and drain them very thoroughly, patting dry with paper towels. They will be softer than fresh peaches but will still taste delicious on the finished tart.

Can I assemble this tart the night before?

It is best to assemble this tart no more than 1 to 2 hours before serving. The mascarpone cream and peaches release moisture that softens the pastry over time. You can bake the pastry shell and prepare the mascarpone cream the day before, then assemble everything fresh before your event.

My pastry border did not puff up much. What went wrong?

This usually happens when the pastry is too warm before baking or when egg wash accidentally seals the scored layers together. Make sure your pastry is cold when it goes into the oven, your oven is fully preheated to 400 degrees, and your score lines are clean cuts without any dragging.

Can I make this recipe gluten-free?

You can try a gluten-free puff pastry if you can find one at your local store; a few brands do make them. Keep in mind that gluten-free puff pastry tends to be a bit less flaky and may behave slightly differently in the oven, so keep a close eye on it during baking.

What if I cannot find mascarpone cheese at my grocery store?

Mascarpone is widely available at most major grocery stores, often in the specialty cheese or deli section. If you truly cannot find it, blend 8 oz of full-fat cream cheese with 2 tablespoons of heavy cream and a small squeeze of lemon juice until very smooth. It is not identical but makes a wonderful and creamy substitute.
