Perfect Sheet Pan Rustic Peach Galette Recipe with Easy Almond Frangipane

“Why don’t you just spread the almond frangipane right on the sheet pan and pile the peaches on top?” my friend asked one humid Saturday afternoon as we wrestled with puff pastry scraps. I started to explain why that wouldn’t work—the frangipane would leak and burn, the peaches would make the dough soggy—then stopped. Honestly, I figured, why not try it her way? It turned out to be a happy accident. The frangipane baked into a golden, nutty layer that soaked up the peach juices perfectly, and the rustic edges crisped up just right without fuss.

That day, I learned that sometimes, the simplest ideas, even when they seem too unconventional, can yield the most delicious results. This Perfect Sheet Pan Rustic Peach Galette with Almond Frangipane became my go-to summer dessert, especially on busy nights when I want something impressive but easy. Maybe you’ve been there—wanting a dessert that feels fancy but doesn’t demand hours in the kitchen or a mountain of dishes. This recipe is exactly that. It’s honest, straightforward, and frankly, it tastes like a little slice of peach heaven. The first time I made it, I forgot to preheat the oven properly and still got a fantastic result. That’s the kind of recipe you want in your back pocket.

Let me tell you, the combination of buttery crust, nutty almond filling, and juicy peaches is something that keeps me coming back season after season. You might find yourself making it again and again too.

Plus, the leftover slices are perfect with a scoop of vanilla ice cream the next day.

What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most are pantry staples, and fresh peaches bring that seasonal magic. Here’s what you’ll need:

• For the crust:
• All-purpose flour, 2 ½ cups (315g) – I recommend King Arthur for consistent results
• Granulated sugar, 2 tablespoons (adds a touch of sweetness)
• Salt, ½ teaspoon
• Unsalted butter, 1 cup (227g), cold and cut into cubes (for that flaky texture)
• Ice water, 5-7 tablespoons (to bring the dough together without melting butter)
• For the almond frangipane:
• Almond flour, ¾ cup (75g) – Bob’s Red Mill works beautifully
• Unsalted butter, 6 tablespoons (85g), softened
• Granulated sugar, ⅓ cup (67g)
• Large egg, 1 (room temperature)
• Pure almond extract, ½ teaspoon (adds depth to the almond flavor)
• All-purpose flour, 1 tablespoon (helps thicken the filling slightly)
• For the topping:
• Fresh peaches, 5-6 medium (about 3 pounds/1.36 kg), sliced (ripeness matters—slightly firm peaches hold up better)
• Granulated sugar, 2 tablespoons (to sprinkle over peaches)
• Fresh lemon juice, 1 tablespoon (balances sweetness and prevents browning)
• Raw sliced almonds, 2 tablespoons (for garnish and crunch)
• Egg wash: 1 egg beaten with 1 tablespoon water (for glossy crust)

Feel free to swap almond flour with finely ground hazelnuts for a different twist or use a dairy-free butter alternative if needed. For gluten-free, you could try a blend of gluten-free flours, but results may vary.

Equipment Needed

• Sheet pan, approximately 18 x 13 inches (46 x 33 cm) – A rimmed baking sheet works best for catching any drips.
• Mixing bowls – One large for dough, one medium for frangipane.
• Pastry cutter or food processor – To cut butter into the flour for flaky crust.
• Rolling pin – To roll out the dough evenly; if you don’t have one, a clean wine bottle works in a pinch.
• Bench scraper or sharp knife – For dividing dough and trimming edges.
• Pastry brush – For applying egg wash.
• Cooling rack – To cool the galette evenly without sogginess.

I’ve tried using silicone baking mats as a non-stick surface, but parchment paper works just as well and makes cleanup a breeze. For the frangipane, a stand mixer is great but a sturdy whisk and elbow grease do the job perfectly.

Preparation Method

1. Make the crust: In a large bowl, whisk together 2 ½ cups (315g) flour, 2 tablespoons sugar, and ½ teaspoon salt. Cut in 1 cup (227g) cold butter using a pastry cutter or food processor until the mixture resembles coarse crumbs with pea-sized bits. Slowly add 5-7 tablespoons ice water, one tablespoon at a time, mixing gently until the dough just comes together. Don’t overwork it—too much handling makes tough crust. Form the dough into a disk, wrap in plastic wrap, and chill for at least 1 hour.
2. Prepare the almond frangipane: Beat 6 tablespoons softened butter and ⅓ cup sugar in a medium bowl until creamy. Add 1 egg and ½ teaspoon almond extract; mix well. Fold in ¾ cup almond flour and 1 tablespoon all-purpose flour until smooth. Cover and set aside.
3. Preheat your oven: Set to 375°F (190°C). Line your sheet pan with parchment paper.
4. Roll out the dough: On a floured surface, roll the chilled dough into a rough rectangle about 12 x 16 inches (30 x 40 cm). Transfer it to the prepared sheet pan. If it cracks, gently press it back together—imperfections add rustic charm.
5. Spread the frangipane: Evenly spread the almond filling over the dough, leaving about a 1-inch (2.5 cm) border all around.
6. Arrange the peaches: Toss sliced peaches with 2 tablespoons sugar and 1 tablespoon lemon juice. Layer the peaches over the frangipane in a single, slightly overlapping layer.
7. Fold and finish: Fold the edges of the dough over the peaches, pleating as needed to create a rustic border. Brush the dough edges with egg wash and sprinkle raw sliced almonds on top.
8. Bake: Place in the oven and bake 40-45 minutes, until crust is golden and peaches are bubbling. Rotate the pan halfway through for even cooking.
9. Cool and serve: Let cool on a rack for at least 20 minutes before slicing. This helps the frangipane set and makes slicing cleaner.

Common hiccup: If your peaches release too much juice, it can make the crust soggy. To avoid this, slightly underripe peaches or patting slices dry before layering helps. Also, don’t skip chilling the dough; it keeps the butter cold and the crust flaky.

Cooking Tips & Techniques

One trick I’ve learned is to keep your ingredients cold, especially the butter and water when making the crust. Cold butter creates steam pockets during baking, which gives you that coveted flaky texture. I once skipped chilling the dough, and the crust turned out dense and tough—lesson learned!

When rolling out the dough, don’t stress about perfect shape. Rustic means relaxed edges and a casual fold. It’s what makes the galette charming (and easier to manage than a pie).

Using almond flour instead of regular flour in the frangipane gives a moist, tender crumb and that wonderful almond flavor. If you want to multitask in the kitchen, make the dough a day ahead and keep it refrigerated—you’ll save time and have it ready when the peaches are prepped.

Watch the galette closely in the last 10 minutes of baking. If the edges brown too fast, loosely tent with foil. The goal is a golden crust without burnt bits.

Variations & Adaptations

• Gluten-free: Swap the all-purpose flour in the crust for a gluten-free blend. I’ve tried Cup4Cup and got great results, though the texture is slightly different.
• Dairy-free: Use a plant-based butter alternative and almond or oat milk if your frangipane recipe calls for any dairy additions.
• Seasonal twists: Replace peaches with nectarines, plums, or berries. For fall, try apple slices with cinnamon and a splash of maple syrup in the frangipane.
• Flavor swaps: Add a tablespoon of orange zest to the frangipane for a citrusy lift, or sprinkle some cinnamon on the peaches before baking for warmth.
• Personal favorite: I once added a handful of chopped pistachios on top of the frangipane before layering peaches. It added a lovely crunch and a pop of color.

Serving & Storage Suggestions

Serve the galette warm or at room temperature, ideally with a scoop of vanilla ice cream or a dollop of whipped cream. The nutty almond frangipane pairs beautifully with a cup of black tea or lightly brewed coffee.

Store leftovers covered tightly in the refrigerator for up to 3 days. Reheat gently in a low oven (about 300°F/150°C) for 10 minutes to bring back the crispness. You can also freeze slices wrapped well in foil and thaw overnight in the fridge before reheating.

Flavors actually deepen after a day, so don’t hesitate to make it ahead of time. The peaches soak into the frangipane even more, creating a rich, almost custardy filling.

Nutritional Information & Benefits

This galette provides a balanced mix of carbohydrates, healthy fats from butter and almonds, and natural sweetness from fresh peaches. Almond flour adds protein and vitamin E, while peaches contribute fiber and vitamin C.
