Rustic Plum Galette with Cornmeal Crust

A plum galette is one of those desserts that feels more composed than casual, even though it asks for very little precision. The fruit is folded into a free-form crust, the edges are turned by hand, and the final result looks unstudied in the best sense. For late summer baking, when stone fruit is still abundant but the season is starting to shift, a plum galette recipe offers a practical and satisfying way to use what is ripe.

This version uses a cornmeal crust, which adds a gentle grit and a faint toastiness that pairs well with plums. The texture is not as delicate as a standard butter pastry, but that is part of its appeal. It holds the filling well, bakes into a crisp base, and gives this rustic fruit tart a more substantial character. If you want an easy free-form pie that feels at home on a weekend table, this is a reliable place to start.

Why Plums Work So Well in a Galette

Plums bring a balance of sweetness and acidity that makes them especially suited to open-faced baking. They soften without collapsing, and their juices concentrate as they bake. In a galette, that means the filling becomes glossy and fragrant while still retaining distinct pieces of fruit.

Several plum varieties work well:

• Italian prune plums — Small, oval, and firm, they hold shape nicely.
• Red plums — Juicy and slightly tart, with an attractive color.
• Black plums — Deeply flavored and sweet, especially good when fully ripe.
• Mixed plums — A combination of varieties adds visual interest and a layered flavor.

Because the crust is simple, the quality of the fruit matters. Use plums that are ripe but not overly soft. If they are too firm, the filling can taste blunt. If they are too soft, the galette may become soggy.

Ingredients You Will Need

This recipe is built from pantry staples and a few seasonal ingredients.

For the Cornmeal Crust

• 1 1/4 cups all-purpose flour
• 1/4 cup fine cornmeal
• 1 tablespoon granulated sugar
• 1/2 teaspoon fine salt
• 1/2 cup unsalted butter, cold and cut into cubes
• 3 to 5 tablespoons ice water

For the Plum Filling

• 1 1/2 pounds ripe plums, pitted and sliced
• 1/4 cup granulated sugar, plus more for sprinkling
• 1 tablespoon cornstarch
• 1 teaspoon lemon juice
• 1/2 teaspoon ground cinnamon
• 1/4 teaspoon kosher salt
• 1 teaspoon vanilla extract, optional

For Assembly

• 1 egg, beaten with 1 tablespoon water or milk
• 1 to 2 teaspoons coarse sugar, for the crust edges
• 1 tablespoon flour, for dusting the work surface
• 1 tablespoon butter, cut into small pieces, optional

Making the Cornmeal Crust

A good galette crust should be sturdy enough to support fruit, but tender enough to cut cleanly. The cornmeal gives structure and a lightly sandy texture without making the pastry heavy.

Step 1: Combine the dry ingredients

In a large bowl, whisk together the flour, cornmeal, sugar, and salt. This helps distribute the cornmeal evenly, which matters for texture.

Step 2: Cut in the butter

Add the cold butter cubes and work them into the flour mixture using a pastry cutter, two forks, or your fingertips. Stop when the mixture resembles coarse crumbs with some pea-sized pieces of butter still visible. Those pieces create flakiness in the oven.

Step 3: Add ice water gradually

Drizzle in the ice water, one tablespoon at a time, mixing lightly after each addition. The dough should begin to clump when pressed but should not feel wet. Depending on humidity and flour type, you may need slightly more or less water.

Step 4: Chill the dough

Gather the dough into a disk, wrap it, and refrigerate it for at least 30 minutes. An hour is even better. Chilling relaxes the gluten and keeps the butter cold, which improves the final texture.

Preparing the Plum Filling

The filling should be simple. Plums do most of the work on their own. The sugar helps draw out juices and encourages browning, while the cornstarch thickens the syrup so the galette does not spread too much on the pan.

Step 1: Slice the fruit

Pit the plums and cut them into wedges. If the plums are medium-sized, six to eight slices per fruit is usually enough. Try to keep the slices fairly even so they bake at the same rate.

Step 2: Toss with the seasoning

In a medium bowl, combine the plum slices with sugar, cornstarch, lemon juice, cinnamon, salt, and vanilla if using. Toss gently until the fruit is coated. Let the mixture stand for about 10 minutes while you roll out the dough.

This brief rest allows the plums to release some juice. If the fruit is especially wet, you can spoon off a tablespoon or two of liquid before filling the galette, though it is not always necessary.

Assembling the Galette

The free-form nature of a galette is part of what makes it appealing. There is no pie dish to navigate and no lattice to calculate. A rustic fruit tart asks for judgment rather than exactness.

Step 1: Roll out the dough

Lightly flour a clean surface and roll the chilled dough into a rough 12-inch circle, about 1/8 inch thick. If the edges crack, press them back together. Imperfections are not a problem here.

Transfer the dough to a parchment-lined baking sheet. A rimmed sheet is important, since some fruit juices may escape during baking.

Step 2: Add the filling

Arrange the plum slices in the center of the dough, leaving a 2-inch border. You can fan them in concentric circles for a neater look, or simply mound them loosely for a more casual presentation. Leave any excess juice in the bowl unless the fruit seems dry.

Step 3: Fold the edges

Fold the dough border up and over the fruit, pleating as you go. The center should remain open. If the dough softens too much, chill the assembled galette for 10 to 15 minutes before baking.

Brush the exposed crust with the egg wash and sprinkle with coarse sugar. If you like a richer finish, dot the filling with a few small pieces of butter before folding. This is optional, but it can add sheen and help the fruit soften evenly.

Baking the Galette

Bake the galette in a preheated 400°F oven until the crust is golden and the filling is bubbling. This usually takes 35 to 45 minutes, depending on your oven and the juiciness of the plums.

Keep an eye on the edges. If they brown too quickly, tent them loosely with foil during the final 10 minutes. The finished crust should be deeply colored but not dark, and the fruit should look thickened and glossy.

Let the galette cool on the baking sheet for at least 20 to 30 minutes before slicing. This resting time matters. The juices need a chance to settle, and the filling will continue to thicken as it cools.

How to Serve It

A plum galette is flexible enough for many settings. It can be served warm, at room temperature, or slightly chilled. The flavor changes subtly with temperature, but the core appeal remains the same.

Some good accompaniments include:

• A scoop of vanilla ice cream
• Softly whipped cream
• Plain Greek yogurt for a less sweet contrast
• Crème fraîche, which echoes the fruit’s acidity
• Toasted almonds, scattered over the top for crunch

If you are serving it after dinner, a small slice is enough. If it appears at brunch or with coffee, larger pieces are reasonable. The cornmeal crust dessert has enough texture and flavor to stand on its own.

Practical Tips for Better Results

A few details make the difference between a good galette and one that feels balanced and clean.

Keep the butter cold

Cold butter is essential for a flaky crust. If your kitchen is warm, chill the flour mixture for a few minutes before adding water, or refrigerate the dough again before rolling.

Control the moisture

Plums vary widely in juiciness. If yours are especially ripe, add a little extra cornstarch, up to 1 1/2 tablespoons total, but do not overdo it. Too much thickener can make the filling pasty.

Use parchment paper

Parchment keeps the galette from sticking and makes cleanup easier. It also allows you to slide the galette onto a serving board more neatly after cooling.

Do not overwork the dough

A rustic fruit tart should not have a tough crust. Mix the dough only until it comes together. Some visible butter pieces are a good sign.

Bake on a preheated sheet if needed

If you want a crisper bottom, place the baking sheet in the oven while it preheats, then slide the parchment and galette onto the hot sheet. Use care, since this adds a bit of handling complexity.

Variations Worth Trying

Once you know the basic formula, the galette can adapt easily.

Add stone fruit

Peaches, nectarines, or apricots can be added alongside the plums. This softens the tartness and makes the filling more varied.

Introduce nuts

A tablespoon or two of finely ground almonds or hazelnuts can be sprinkled over the dough before the filling goes on. This creates a barrier that helps absorb juice.

Change the spice profile

Cinnamon is familiar, but cardamom, ginger, or a small pinch of nutmeg can add dimension. Use a light hand so the plums remain central.

Substitute another crust element

If you want more texture, replace up to 2 tablespoons of flour with additional cornmeal. The crust will be more rustic and slightly more crumbly, which may suit some palates better than others.

FAQ’s

Can I make the dough ahead of time?

Yes. The dough can be refrigerated for up to 2 days before rolling. You can also freeze it for up to 1 month. Thaw it in the refrigerator overnight before using.

Do I need to peel the plums?

No. The skins soften during baking and contribute color and structure. Leaving them on is standard for this plum galette recipe.

What if my plums are very tart?

Increase the sugar in the filling by 1 to 2 tablespoons, depending on taste. You can also serve the galette with a sweeter accompaniment, such as vanilla ice cream.

Can I make this without cornmeal?

Yes, but the texture will change. You can replace the cornmeal with flour for a more traditional crust. Still, the cornmeal is part of what gives this version its character.

How do I keep the bottom from getting soggy?

Use ripe but not overly juicy plums, add the correct amount of cornstarch, and bake until the filling is visibly bubbling. A hot baking sheet can also help.

Can I reheat leftovers?

Yes. Warm slices in a 300°F oven for about 10 minutes. This restores some of the crust’s texture better than a microwave would.

Conclusion

A rustic plum galette with a cornmeal crust is a straightforward dessert with enough nuance to feel thoughtful. It is shaped by season, by fruit quality, and by a pastry that is simple but not plain. For late summer baking, it offers an easy free-form pie that can be made without special equipment or elaborate technique. The result is a rustic fruit tart with crisp edges, soft fruit, and a balance of textures that makes each slice feel complete.
