Mixed Berry Galette
Inside: The secret ingredient that prevents a runny fruit juice mess and gives your berry galette the perfect gooey-gooey filling everyone craves.
This berry galette loaded with ripe summer strawberries, blueberries and cherries is a quintessential summer dessert. A rustic fruit tart, you can substitute other fruits like raspberries or blackberries with a scoop of vanilla ice cream for a red, white and blue dessert that’s perfect for 4th of July.

A galette is a rustic, free-form fruit tart– a.k.a. a crostata. It can be made with most any type of fruit, from apples and pears to strawberry and rhubarb.
This berry galette is one of my favorites because you can use one berry or a mixture of several types.
If you want a dessert perfect for patriotic red, white, and blue-themed holidays, I recommend using a combo of 2-3 of these: strawberries, blackberries, blueberries, raspberries, or cherries.
Why we love a berry galette:
- You can use any mix of berries and it can be fresh or frozen fruit.
- Make your own pastry, or use a store-bought crust.
- It’s a quick and easy summer dessert.
- It’s like a free-form pie, so there’s no fussy decorating or lattice work.
- The secret must-have ingredient for making perfect pies, tarts and berry galette.
Ingredients:

- 9″ Pie Pastry– You can use your favorite crust recipe, try this cream cheese pastry crust, or use store-bought pastry.
- Berries – use one type or a mixture of different berries from strawberries and raspberries, to blueberries, blackberries or mulberries.
- Granulated Sugar – do not use brown sugar or sugar substitute.
- Instant ClearJel – the secret ingredient. This thickener works on any juicy fruit and saves time on assembly. See all the benefits of this secret ingredient below.
- Lemon Juice – fresh squeezed is best.
- Half and Half – for brushing the pastry and helping it brown.
- Sparkling Sugar – optional, but adds a crunch to the berry galette.
Instant ClearJel – the best thickener for fruit fillings:
When making galettes, crostatas, fruit tarts and pies, one thing to watch for are leaks – fruit juices escaping from the confines of the fruit and oozing through (or over) the crust; flooding the baking sheet. Aside from the inherent mess it makes, you want to keep those juices (and flavors) in the dessert.
I’ve tried thickeners like cornstarch, arrowroot and tapioca to varying degrees of success, and always with a bit of frustration.
- Cornstarch has to be mixed with a cold liquid before being mixed with simmering fruit to thicken it.
- Tapioca needs to be blended from pearls to a fine powder; it can be blended with the fruit, but it has to sit for 10 minutes to absorb before baking.
- Flour can be an effective thickener, but NOT for fruit fillings.
Instant ClearJel is a modified food starch, with unique properties…
- No need to mix it with liquid before being added to bubbling fruit to thicken.
- No more cloudy fruit filling the fruity goo remains clear like juice, just thicker.
- Add it to uncooked fruit with stellar results.
- If you’re freezing pies (either before or after baking) Instant ClearJel will prevent the fruit from leaking like the Kilauea lava streams.
Step-by-step instructions:

- Roll out the pastry dough into an 11″ circle and transfer to a parchment-lined baking sheet.

2. Rinse the berries and transfer them to a medium bowl. If you use strawberries, remove the stems and cut them into pieces commensurate with the other fruit. Add the lemon juice and toss to combine.

3. In a small bowl, combine the sugar and Instant ClearJel. Whisk to combine.

4. Add the sugar mixture to the berries.

5. Carefully fold the sugar and food starch into the berries until they’re well coated.

6. Pile the berry mixture into the center of the galette crust.

7. Fold over the fruit to hold it in the galette, with the fruit peaking out of the top. Brush the crust with half and half. If using sparkling or coarse sugar, sprinkle it over the fruit and crust. Bake at 450° F for 20-22 minutes.

8. Bake until the crust is golden brown. Let the berry galette cool for a few minutes before slicing. Serve warm.
Pro-Tips:
- Chill the crust on the sheet pan until you assemble the galette. Cold crust bakes to a flakier finish.

Variations:
- Use one type of berry for the galette instead of multiple.
- Swap another liquid for the lemon juice, such as Cointreau, Kirsch or brandy.
- If you don’t have half and half, use whole milk or a simple egg wash brushed over the pie crust to help it brown and become golden.

FAQs
Most of the sogginess in the crust comes from the juices that naturally ooze from the fruit and berries. Using Instant ClearJel thickens the fruit without the leak and keeps the pastry from absorbing excess liquid.

- ¼ cup sugar
- 2 tablespoons Instant ClearJel
- 4 cups mixed berries I used strawberries, blueberries and raspberries

DIRECTIONS:
- Preheat the oven to 450°. Line a half sheet pan with a silpat or parchment paper. Set aside.
- Line a work surface with plastic wrap. Set the pie pastry in the center and lay another layer of plastic wrap over the pastry. Use a rolling pin to roll out the pie pastry to about 10″-11″ round. Remove one layer of plastic and turn the pie pastry out onto the silpat. Remove the other layer of plastic wrap and discard.
- Wash the berries with cool water. If using strawberries, remove the stems and cut into quarters or eighths depending on how large they are. Combine the berries in a large bowl and set aside.

- Sprinkle the sugar mixture over the berries and carefully fold it into the berries until the fruit is well coated.
- Pile the berries into the center of the pie crust, leaving about 1 1/2″ – 2″ border. Fold the edges of the pastry over the berries, overlapping and lightly pinching at the edges.
- Brush the pastry with creamand sprinkle the entire tart with sparkling sugar. Bake for 20-25 minutes or until the pastry is golden and the center is bubbly. Tart may leak, but that’s ok,
- Let the tart rest for 20 minutes or to room temperature then transfer to a serving platter to slice. Serve with ice cream, whipped cream or powdered sugar.

Hi Lisa, thank you so much for this recipe, had tried other galettes in the past, that never worked. Today I tried this beautiful one with strawberries, raspberries and blueberries.. I however added a bit more sugar because the blueberries were tart, and had to bake it for 35 min. Next time around I will try this recipe with 3 cups of fruit, because I like to have the crust come up and over more than this did. This tasted better a few hours after taking it out of the oven, when some of the berry flavor permeated the crust. When we tried a piece fairly soon after taking it out of the oven, the crust tasted like flour… not in a good way in my opinion. So do let it rest! The trick of using the Clear Jel (I only had Clear Jel not Instant Clear Jel) works like a charm! So thank you for that Lisa, and for the beautiful pictures walking us through the recipe! The fear of gallette making is gone!
I’m so glad it worked well for you, Ann! Thanks for letting me know — good tip on letting it sit for a while.
