Blistered Zucchini & Comté Rough-Puff Bandes
When summer zucchini threatens to take over the kitchen counter, you need a strategy that isn't another loaf of bread. Inspiration hit during a frantic Sunday service prep in San Francisco, when I needed something fast, deeply savory, and aggressively flaky to feed the line cooks. Butter is not a garnish, and this lamination-lite method proves you do not need to spend your entire weekend turning butter blocks to get café-level results. We use a quick rough-puff pastry, smear it with sharp Dijon mustard, blanket it with aged Comté, and top it with salted, paper-thin zucchini ribbons that blister and caramelize in a hot oven. Why it works: the salt draws out the excess water from the zucchini so the pastry stays crisp instead of soggy, giving you that lacy, shatteringly crisp crumb we all chase. Make it your own by swapping the Comté for Gruyère or sharp cheddar depending on what is lurking in your cheese drawer. Let time do the work, and do not skip salting the zucchini first. Don't skip this.

Timeline
Ingredients
- 250 g all-purpose flour(cold)
- 200 g unsalted cultured butter(very cold, cut into 1/2-inch cubes)
- 1 tsp fine sea salt
- 100 ml ice water(plus 1-2 tbsp extra if needed)
- 2 medium zucchini(about 400g total, sliced paper-thin on a mandoline)
- 1 tsp kosher salt(for purging zucchini moisture)
- 120 g Comté cheese(coarsely grated (Gruyère works too))
- 2 tbsp Dijon mustard(smooth, sharp French Dijon)
- 1 large egg(for egg wash)
- 1 tbsp heavy cream(for egg wash)
- 1 tbsp fresh thyme leaves
- 1 tsp lemon zest(freshly grated)
- 1/2 tsp flaky sea salt(Maldon or similar)
- 1/2 tsp black pepper(freshly cracked)
- 1 tsp lemon zest(Mentioned in step 9 but not listed in ingredients.)
- 1/2 tsp black pepper(Mentioned in step 6 but not listed in ingredients.)
Instructions
- 1
In a large bowl, toss 250 g all-purpose flour and 1 tsp fine sea salt together. Add 200 g unsalted cultured butter. Coat the butter cubes in flour, then press each cube flat between your thumb and forefingers into shaggy sheets. Drizzle in 100 ml ice water and mix with a fork until the dough barely clumps together.
10 min
Tip: Do not knead until smooth! You want visible, cold butter chunks; this is what creates lacy, shatteringly flaky layers without full French lamination.
- 2
Tip the shaggy dough onto a work surface, shape into a rough rectangle, wrap tightly in plastic, and chill in the refrigerator.
30 min
Tip: Let time do the work. Cold butter is non-negotiable for lift.
- 3
While dough rests, slice 2 medium zucchini paper-thin using a mandoline. Toss with 1 tsp kosher salt in a colander set over a bowl. Let sit to draw out liquid.
15 min
Tip: Excess moisture is the enemy of crisp dough. Skimping here yields a soggy bottom tight like a bad alibi.
- 4
Unwrap the dough on a lightly floured surface. Roll into a 6x18-inch rectangle. Fold the bottom third up and top third down like a letter (tour simple). Turn dough 90 degrees, roll out again to 6x18 inches, and repeat the letter fold. Wrap and chill for 20 minutes.
15 min
Tip: Two quick folds give you 90% of traditional puff pastry layers in a fraction of the time.
- 5
Preheat your oven to 425°F (220°C) with a heavy baking sheet lined with parchment inside.
20 min
Tip: Preheating the sheet tray creates an instant blast of heat that sets the bottom crust instantly.
- 6
Transfer salted zucchini to a clean kitchen towel or cheesecloth. Squeeze firmly to wrung out every drop of moisture. Toss squeezed zucchini ribbons with 1 tbsp fresh thyme leaves and 1/2 tsp black pepper.
10 min
Tip: Don't skip this: squeeze until the zucchini feels nearly dry to the touch.
- 7
Roll chilled dough into a 10x14-inch rectangle, about 1/4-inch thick. Cut lengthwise into four long 2.5x14-inch strips (bandes). Spread 2 tbsp Dijon mustard down the center of each strip, leaving a 1/2-inch border. Top with 120 g Comté cheese and layer the dry zucchini ribbons down the length.
12 min
Tip: Keeping a border gives the puff room to rise tall around the savory filling.
- 8
Whisk 1 large egg with 1 tbsp heavy cream. Brush dough borders generously with egg wash. Carefully slide parchment with assembled bandes onto the preheated hot baking sheet. Bake at 425°F for 22-25 minutes until pastry is puffed, deeply bronzed, and edges are blistered.
25 min
Tip: Look for a deep mahogany-gold color; pale pastry lacks flavor and crunch.
- 9
Remove from oven, sprinkle warm pastries with 1 tsp lemon zest and 1/2 tsp flaky sea salt. Let cool on a wire rack for 5 minutes before serving warm.
3 min
Tip: The hit of lemon zest cuts right through the buttery richness of the pastry and Comté.
Chef's Notes
Cami's shortcut note: Rough puff (feuilletage rapide) gives you 90% of classic puff pastry's shatter-crisp lamination with zero tears. The secret isn't folding for hours—it's keeping the butter cold and baking on a preheated baking sheet so the bottom crust sears crisp immediately. Don't skip squeezing the salted zucchini dry; excess water will ruin your crumb structure into a soggy mess.

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.
