Café-Style Wild Mushroom & Melted Brie Chaussons
Classic French chaussons (turnovers) are usually stuffed with apples. Growing up in Paris, they were my daily after-school snack, but walking through Bay Area farmers' markets today, I realized we're not suffering for brunch. I wanted that lacy, shatteringly crisp pastry wrapped around something rich and savory. These pockets are packed with hard-seared wild mushrooms, a confident swipe of sharp Dijon, and molten Brie. What makes this recipe special is the weeknight method. Traditional lamination is a three-day commitment. Instead, grating frozen butter directly into the flour is my ultimate shortcut. Why it works: the frozen shards stay intact, creating rapid steam pockets in the hot oven for maximum crust-to-crumb ratio without the fuss. Don't skip the hard sear on the mushrooms; moisture is the enemy of flake, and a soggy pastry is tight like a bad alibi. To make it your own, swap the Brie for a funky Camembert or fold toasted walnuts into the mix. Cami's shortcut note: Mix your rough puff Friday, let time do the work in the fridge overnight, and bake Saturday until deep golden brown and bubbling. Remember, butter is not a garnish.

Timeline
Ingredients
- 250 g all-purpose flour(Plus extra for dusting)
- 1.5 tsp kosher salt(Divided (1 tsp for dough, 1/2 tsp for mushrooms))
- 200 g frozen cultured butter(Unsalted; must be frozen solid for grating)
- 100 ml ice water(Keep it ice cold)
- 300 g mixed wild mushrooms(Maitake, oyster, or shiitake, torn by hand)
- 1 tbsp olive oil(For searing)
- 1 tbsp fresh thyme leaves(Chopped)
- 150 g double-cream Brie(Chilled for clean slicing)
- 2 tbsp Dijon mustard(Adds acidity to cut the richness)
- 1 tbsp apple cider vinegar(For deglazing)
- 1 egg(Beaten, for egg wash)
- 1 tsp flaky sea salt(For finishing)
- 0.5 tsp half teaspoon kosher salt(mentioned in step 3 but not listed)
Instructions
- 1
Grate 200g frozen cultured butter into a bowl containing 250g all-purpose flour and 1 tsp kosher salt. Toss to coat the shreds—butter is not a garnish, it is the entire architecture of your flake. Drizzle in 100ml ice water and squeeze just until shaggy. Roll into a rough rectangle on your counter, fold it like a business letter, rotate 90 degrees, and repeat the fold twice more. Wrap it tightly and get it into the fridge.
10 min
Tip: Work quickly so the butter stays cold. If it starts melting, pop everything in the freezer for 5 minutes.
- 2
While the dough chills, heat 1 tbsp olive oil in a wide cast-iron skillet over medium-high heat. Tear 300g mixed wild mushrooms into bite-sized pieces and drop them in. Do not crowd the pan, and do not stir them. We want a hard sear, not a sad steam. Let them go undisturbed for 4 minutes.
5 min
Tip: Tearing mushrooms instead of slicing them creates craggy edges that crisp up beautifully in the pan.
- 3
Once the mushrooms have a deep, unapologetic brown crust, give them a toss. Stir in 1 tbsp fresh thyme leaves and 1/2 tsp kosher salt. Deglaze the pan with 1 tbsp apple cider vinegar, scraping up the browned bits from the bottom. Transfer to a plate to cool completely.
8 min
Tip: Cooling the filling is non-negotiable. Hot mushrooms will melt your dough's butter before it hits the oven.
- 4
Preheat your oven to 400°F (200°C). Slice 150g double-cream Brie into thick slabs. The fridge is your friend here—let time do the work and allow the dough to rest a full 30 minutes total while the oven preheats. This relaxes the gluten so your pastry does not bake up tight like a bad alibi.
17 min
Tip: Keep the Brie in the fridge until the very last second so it holds its shape during assembly.
- 5
On a lightly floured surface, roll the chilled dough into a 12x12-inch square. Cut into 4 equal smaller squares. Smear 2 tbsp Dijon mustard evenly across the centers. Divide the Brie slabs and cooled mushroom mixture among the squares, keeping the borders clean.
10 min
Tip: If the dough shrinks back when you roll it, walk away for 5 minutes. Don't fight it.
- 6
Fold each square diagonally corner-to-corner to form a triangle—these are your chaussons, or turnovers. Crimp the edges firmly with a fork to seal. Beat 1 egg and brush it generously over the tops. Sprinkle with 1 tsp flaky sea salt and score a small vent hole in each pastry so steam can escape.
5 min
Tip: Avoid getting egg wash on the cut edges of the pastry; it acts like glue and stops the rough puff from rising.
- 7
Bake for 25 minutes until puffed, shatteringly crisp, and deeply golden. The cheese might bubble through the vents—this is a good thing. Let them cool slightly on a wire rack before eating, as molten Brie is a hazard.
25 min
Tip: Look for a rich mahogany color on the crust. Pale pastry is underbaked pastry.
Chef's Notes
Cami's shortcut note: Quick lamination works because the frozen butter shreds mimic the thin layers of a traditional butter block. Don't skip chilling the dough; warm butter absorbs into the flour, leaving you with a dense crust instead of flakes. Let time do the work, and your oven will reward you with maximum crust-to-crumb ratio.
Camille Roux
Café-level bakes, weeknight methods, zero compromise.
Camille “Cami” Roux was born in Paris with flour in her hair and a healthy skepticism of culinary dogma. She grew up around neighborhood boulangeries that treated crust and crumb like religion—but what stuck with her wasn’t rigid tradition. It was the quiet precision: good butter that actually tastes like milk, patient fermentation that builds flavor for free, and desserts that know when to stop before they get cloying. After moving to the Bay Area, Cami trained in a bread-and-pastry scene obsessed with texture, naturally leavened doughs, and seasonal fruit—Tartine energy, minus the martyrdom. She became known for loaves that sing when they cool, jammy tarts with clean edges, and “how is this so good?” weeknight pastries made with a few smart shortcuts. Her motto is high impact, low fuss: splurge where it counts (butter, salt, time), streamline the rest (sheet pans, one bowl, cold-proofing). If it doesn’t improve flavor or structure, it doesn’t earn a step.
