Ingredients for au bon pain spinach and cheese croissant

Master these 14 ingredients for restaurant-quality croissants with signature flaky layers and herbed cheese filling.

The butter quality makes or breaks these croissants. Plugrá or European-style unsalted butter from specialty stores like Whole Foods or Williams Sonoma delivers the best flavor and texture. Keep it cold—cold butter creates those signature flaky layers. The flour should be high-protein (11-12% protein) for structure, like King Arthur or Gold Medal. For the cheese filling, Cabot or Babybel sharp white cheddar melts beautifully without becoming greasy. Fresh herbs are non-negotiable—dried won't give that bright, fresh flavor you crave in every bite.

No European butter? Land O'Lakes or Parkay works in a pinch, though the flavor won't be as rich. Substitute the chives with green onions at double the amount if they're all you have. For the spinach, frozen works if thawed and squeezed dry, but fresh is ideal for that vibrant color. The egg wash can be made ahead—just whisk it up right before baking. If you're concerned about the dough being too sticky, add ice cubes gradually while mixing rather than all at once. The cornstarch isn't just for dusting—it helps prevent the dough from sticking to your hands during folding.

Store the puff pastry dough between parchment paper in the fridge for up to 2 days—this actually improves the flavor as the butter solidifies. The filled croissants can be shaped and refrigerated overnight, then baked straight from the fridge for perfect results. Once baked, they're best served warm, but you can reheat them in a 350°F oven for 5-10 minutes to restore that crispy crust. For make-ahead convenience, freeze unbaked croissants on a tray before transferring to a bag—they'll keep for 1 month and bake straight from frozen with 5-10 extra minutes.

Step-by-step instructions for spinach and cheese croissants

Master the art of flaky layers with this professional croissant technique.

In a large mixing bowl, combine the 4 cups all-purpose flour and 0.5 tsp diamond crystal kosher salt. Cut in the 1.5 cups unsalted butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs with pea-sized butter pieces. This cold butter will create those signature flaky layers.

Gradually add the 0.5 cup ice water while mixing just until the dough comes together. Avoid overworking—handle only until the dough forms a shaggy mass. Turn it out onto a lightly cornstarch-dusted surface and gently shape into a 12x8-inch rectangle. Wrap tightly in plastic and refrigerate for 1 hour. Cold dough layers better and prevents gluten development.

In a skillet, heat the 1 tbsp extra-virgin olive oil over medium heat. Add the 4 oz fresh spinach and sauté for 2-3 minutes until just wilted. Add the 1 minced garlic clove and cook for 30 seconds until fragrant. Transfer to a bowl and let cool completely.

In a separate bowl, combine the cooled spinach mixture with 1 cup freshly grated sharp white cheddar cheese, 2 tbsp finely chopped fresh chives, and 2 tbsp finely chopped fresh parsley. Mix gently to distribute the herbs evenly. This filling should be cool enough to handle when incorporated into the dough later.

Roll the chilled dough into a 14x10-inch rectangle on a cornstarch-dusted surface. Spread the 0.25 cup cold heavy cream evenly over the dough, leaving a ½-inch border around the edges. This prevents the filling from touching the dough directly, which would create steam and break the layers.

Sprinkle the herbed spinach and cheese filling evenly over the cream, staying within the ½-inch border. Roll the dough tightly into a log, sealing the edge firmly. Fold the log in thirds like a letter, then turn it 90 degrees and fold again into thirds. Wrap tightly and refrigerate for 30 minutes to relax the gluten.

Divide the dough into 6 equal pieces (about 3 oz each). Roll each piece into a 12-inch rope, then coil into a crescent shape with the point facing up. Place on a parchment-lined baking sheet, spacing 2 inches apart. Cover with a clean kitchen towel and let proof at room temperature for 1-2 hours until puffed about 50%.

While proofing, preheat your oven to 375°F. Brush the croissants with an egg wash made from 1 beaten large egg and 1 tbsp granulated sugar. The sugar creates a beautiful caramelized crust. Bake for 20-25 minutes until golden brown and internal temperature reaches 190°F. Rotate the pan halfway for even browning.

Remove from oven and let cool on a wire rack for 10 minutes. The croissants will continue setting as they cool. For maximum flakiness, slice into ½-inch thick pieces and serve warm. The layers should separate cleanly with minimal effort—a testament to your perfect laminations.

Here's the thing about these croissants—they're best served immediately while the layers are at their peak crispness. The cheese filling stays warm and gooey, while the pastry maintains that signature buttery crunch. Store any leftovers wrapped in a clean kitchen towel to preserve their texture.

French Bakery Style

Au Bon Pain's original spinach and cheese croissant draws from classic French viennoiserie techniques. The key is using Plugrá butter (or high-fat European-style butter) for those signature flaky layers.

French bakeries achieve this by keeping all ingredients cold—especially the butter—and using a laminating technique where butter sheets are encased between dough layers. The 3-fold method (folding the dough in thirds three times) creates the maximum number of layers for that iconic crispy texture. 🥖

American Brunch Adaptation

This recipe's American twist comes from the herbed cheese filling—something you won't find in traditional French croissants. The combination of sharp white cheddar, sautéed spinach, and fresh herbs creates a brunch-friendly version perfect for weekend gatherings.

Unlike savory French pastries, this version often includes a slightly sweeter egg wash (with sugar) to balance the savory filling. Many home bakers add a touch of nutmeg to the cheese mixture for extra depth, which is a common American brunch spice.
