Au Bon Pain Spinach and Cheese Croissant Recipe: Flaky Layers with Herbed Cheese Filling

This Au Bon Pain spinach and cheese croissant recipe delivers the same legendary flaky layers and herbed cheese filling you crave—right in your own kitchen. The secret lies in mastering the laminated butter technique, where thin sheets of dough and cold butter create those signature crisp, airy pockets.

I've perfected this method over years of baking, ensuring every bite reveals that buttery, melt-in-your-mouth texture you expect from the iconic bakery.

The filling transforms simple ingredients into something extraordinary: wilted spinach and sharp cheddar blended with fresh herbs and garlic, creating a rich, savory center that stays perfectly gooey. The key steps—folding the dough precisely, chilling at each stage, and proofing just enough—are what separate homemade croissants from store-bought disappointments.

This isn't just a recipe; it's a technique that transforms ordinary ingredients into something restaurant-worthy.

What you'll end up with is a golden, flaky croissant with layers so delicate they seem almost translucent, filled with a creamy spinach-cheese mixture that melts at the slightest warmth. The aroma alone—warm butter, garlic, and melted cheese—will have everyone at your table asking for seconds.

Each bite combines crispy, buttery pastry with the rich, herby filling, creating a balance that's impossible to resist.

Serve these warm from the oven, sliced lengthwise to reveal the perfect golden layers and creamy filling inside. They're ideal for brunch, appetizers, or a special weekend treat. With this recipe, you'll finally understand why Au Bon Pain's croissants are legendary—and how to make them at home with confidence.

Ingredients for au bon pain spinach and cheese croissant

Mastering laminated dough and herbed cheese filling transforms simple ingredients into legendary Au Bon Pain-style croissants.

The butter selection is non-negotiable—European-style unsalted butter with at least 82% fat content is essential for those signature flaky layers. Plugrá or Kerrygold are my go-to brands, and you must keep it stone-cold throughout the lamination process. The flour should be high-protein (11-12% protein), with King Arthur or Caputo bread flour being ideal choices. If you're using all-purpose, sift it twice to eliminate any lumps that could disrupt the delicate dough layers. For the cheese filling, aged sharp white cheddar is critical—young cheddar lacks the tangy depth needed. Look for cheeses aged at least 6 months from specialty cheese shops or well-stocked grocery stores like Whole Foods or Eataly.

No European butter? Land O'Lakes or Challenge brand will work in a pinch, though they lack the same fat content. For the spinach, frozen works perfectly if thawed and squeezed dry—no one will notice the difference. Substituting the chives and parsley with 1 tbsp dried mixed herbs at half the amount is an option, though fresh herbs elevate the filling significantly. The heavy cream can be swapped for Greek yogurt thinned with milk for a lighter texture, though it won't be as rich. If you're short on time, pre-shredded cheese is acceptable, but grating your own ensures better flavor and texture. The roasted garlic adds sweetness—if you skip it, add an extra 0.5 tsp garlic powder to compensate.

The laminated dough must be kept cold at all times—use your freezer as a work surface when needed. The butter blocks should remain firm but pliable throughout the folding process. For the filling, mix all ingredients and chill for at least 1 hour before rolling into the dough to prevent melting. Properly assembled croissants will keep in the refrigerator for 2 days before baking, though they're best enjoyed fresh from the oven. Once baked, they'll stay crisp for 24 hours at room temperature, but the layers soften over time. For longer storage, freeze the unbaked croissants on a tray before transferring to a bag—they'll keep for 3 months this way.

Step-by-step instructions for flaky spinach and cheese croissants

Mastering the croissant's signature layers requires precision and patience—here's how to achieve that buttery, flaky perfection with a savory spinach-cheese filling.

In a large mixing bowl, combine the 5 cups all-purpose flour and 0.5 tsp 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 texture is crucial—it ensures proper lamination later.

In a separate bowl, whisk together the 2 whole large egg yolks, 0.25 cup granulated sugar, 0.25 cup whole milk, and 1 tbsp nutritional yeast. Gradually incorporate this liquid mixture into the dry ingredients, mixing just until a shaggy dough forms. Avoid overworking the dough at this stage—you want to preserve the gluten structure for those delicate layers.

Turn the dough onto a lightly floured surface and knead gently for 3-4 minutes until smooth but still slightly tacky. Shape into a rectangle, wrap tightly in plastic wrap, and refrigerate for at least 1 hour. This resting period allows the gluten to relax, making the dough more pliable for lamination.

Roll the chilled dough into a 12x8-inch rectangle (about ¼-inch thick) on a lightly floured surface. Fold the dough into thirds like a letter, creating three equal horizontal layers. This is your first fold—rotate the dough 90 degrees and repeat the rolling and folding process for a total of 4 folds. Each fold increases the number of butter layers exponentially, which is what creates those signature flakes.

After the final fold, wrap the dough tightly in plastic and refrigerate for 30 minutes. This brief rest prevents the dough from shrinking during the next rolling. Preheat your oven to 375°F while the dough rests—you'll need it ready for the final proofing step.

In a small skillet, sauté the 3 cloves minced fresh garlic in 1 tbsp butter over medium heat for 1 minute until fragrant. Add the 4 oz finely chopped fresh spinach and cook until just wilted, about 2 minutes. Transfer to a bowl and stir in the 1.5 cups freshly grated sharp white cheddar cheese, 0.25 cup heavy cream, 0.25 tsp baking powder, and 0.25 tsp freshly cracked black pepper. Mix until fully combined and let cool completely.

In a separate small bowl, combine the 0.25 cup finely chopped fresh chives and 0.25 cup finely chopped fresh parsley. Set aside—these herbs will add brightness to the rich cheese filling. Once the spinach-cheese mixture has cooled, fold in the herb blend gently to maintain texture.

Roll the laminated dough into a 16x12-inch rectangle (about ⅛-inch thick). Cut the dough into 8 equal rectangles (each about 4x3 inches). Using a sharp knife or bench scraper, carefully cut each rectangle diagonally from one corner to the opposite corner, creating two triangular pieces. This creates the classic croissant shape.

Place 1 teaspoon of the spinach-cheese filling near the wide end of each triangle. Fold the dough over the filling to completely enclose it, then roll each triangle gently from the wide end toward the point, sealing the edges with a bit of egg wash (1 egg yolk beaten with 1 tbsp water). Arrange the croissants on a parchment-lined baking sheet, leaving 1 inch between each.

Cover the shaped croissants loosely with plastic wrap and let them proof in a warm place for 1-1.5 hours, or until they've risen by about 50%. The dough should feel slightly springy when pressed gently—this indicates proper proofing. Preheat your oven to 375°F while the croissants proof.

Brush the tops of the croissants with additional egg wash for a golden finish. Bake for 20-25 minutes until they're deep golden brown with crisp, flaky layers. Rotate the baking sheet halfway through for even browning. For extra crispiness, transfer to a wire rack and let cool for 5 minutes before serving warm.
