Rhubarb Galette with Almond Frangipane Filling: Rustic Tart Recipe

This rhubarb galette features a flaky, buttery crust (optionally gluten-free), a creamy almond frangipane layer, and sweet-tart rhubarb slices glazed with cinnamon and cardamom.

What is a Galette?

Galettes are free-form, single-crust pies that celebrate rustic beauty over perfection. They’re easier to assemble than a traditional pie and have a warm, homey look. Focus on simple pleasures—the pink of rhubarb, the flour-dusted parchment, the folded crust—and enjoy the comforting aroma of cinnamon and cardamom as it bakes.

Why You’ll Love This Rhubarb Galette

This galette pairs a crisp, buttery crust with a lush almond frangipane and bright rhubarb slices spiced with cinnamon and cardamom. The almond filling adds sweetness and structure, balancing the rhubarb’s tartness so the galette can be eaten by hand or plated with a fork. Serve slightly warm with whipped cream or a scoop of vanilla ice cream for a simple, memorable dessert.

Ingredient Notes

Almond Filling Ingredients

• Unsalted butter (softened)
• Organic cane sugar or granulated sugar
• Large egg (white and yolk separated)
• Vanilla paste or extract
• Almond extract
• Almond flour
• Pinch of salt

Rhubarb

• Rhubarb stalks (trimmed and cut)
• Organic cane sugar or granulated sugar
• Cinnamon
• Ground cardamom
• Pinch of salt

Dough & Assembly

• Gluten-free or regular flour (for dusting)
• Half batch of pie dough (gluten-free or regular—see tips)
• Butter (cut into small pieces)

For Serving (optional)

• Whipped cream or vanilla ice cream

Step-by-Step Instructions

Make the Almond Filling

1. Preheat the oven to 425˚F (220˚C).
2. In a bowl, mash the softened butter and sugar together. Stir in the egg yolk (reserve the egg white for brushing the crust), vanilla, and almond extract. Add the almond flour and a pinch of salt, stirring until the mixture is damp and clumpy.

Prep the Rhubarb Mixture

1. In a bowl, toss the rhubarb pieces with sugar, cinnamon, cardamom, and a pinch of salt until evenly coated.

Assemble the Galette

1. Let the dough warm slightly at room temperature for 10–30 minutes until cool but pliable. Lightly dust a large piece of parchment with flour and roll the dough to about 1/8-inch thickness (roughly 12 inches across). If it cracks, it’s too cold; if it’s sticky, chill it briefly.
2. Slide the parchment and dough onto a baking sheet. Spread the almond filling in the center with lightly damp fingers, leaving a 2-inch border.
3. Arrange the rhubarb over the almond layer in a single even layer and sprinkle any remaining sugar-cinnamon mixture over the fruit. Fold the dough edges up around the filling, patch any tears, and chill the galette for 5 minutes.

Finish and Bake

1. Dot the rhubarb with small pieces of butter. Whisk the reserved egg white and brush it over the dough edges to encourage browning (or brush with cream or milk). Bake until the crust is golden and the rhubarb is tender, about 30–35 minutes.
2. Cool slightly, then serve warm or at room temperature with whipped cream or vanilla ice cream if desired.

Recipe Tips

• The pie dough recipe makes two galettes; freeze one disc wrapped tightly in plastic for later use.
• Bring dough to the right temperature before rolling: too cold and it cracks, too warm and it will be sticky.
• Roll the dough on parchment so it’s easy to transfer to the baking sheet; bake on that same parchment.
• Use damp fingers to press the almond filling evenly, leaving a 2-inch border for folding.
• Use about ¾ pound (≈3 large stalks) rhubarb, cut into 3-inch pieces and arranged in a single layer.
• If you prefer, substitute cream or milk for the egg wash or skip the wash entirely.
• Galettes are rustic by nature—don’t aim for perfection; the result will still be delicious.

Serving and Storage Tips

Serve slightly warm or at room temperature with whipped cream or a scoop of vanilla ice cream. This galette is best the day it’s made; store leftovers in an airtight container in the refrigerator and enjoy them cold or gently reheated.

More Delicious Recipes

• Try classic fruit or savory galettes using the same dough: strawberry, peach, pear, or a savory vegetable tart all work well.
• Roasted rhubarb compote also pairs beautifully with yogurt, shortcakes, or ice cream.
