Ingredients

Dough

• 2 cups all-purpose flour
• ½ cup sourdough starter (active and bubbly)
• ¼ cup whole milk (room temperature)
• 2 tbsp granulated sugar
• 1 tsp salt
• 1 large egg
• 1 cup cold unsalted butter (for lamination)

Filling

• 1 cup shredded Gruyère cheese (or Swiss cheese)
• ¾ cup diced ham (smoked or honey ham)
• 1 tbsp Dijon mustard (optional, for spread)
• 1 egg (for egg wash)

Instructions

1. Activate Your Sourdough Starter
   Feed your starter about 4–6 hours before beginning. It should be bubbly and double in size before you start mixing the dough.
2. Mix the Dough
   In a large mixing bowl, combine flour, sugar, salt, and the active sourdough starter. Add milk and egg. Mix until a shaggy dough forms. Knead lightly for 5 minutes until the dough comes together. Do not overwork it.
3. Chill the Dough
   Shape the dough into a rectangle, wrap it in plastic, and refrigerate for 1 hour. Cold dough is essential for lamination.
4. Prepare the Butter Block
   Place cold butter between two sheets of parchment paper. Pound and roll it into a 6×6 inch square. Keep it chilled but pliable.
5. Laminate the Dough
   Roll out the chilled dough into a 10×10 inch square. Place the butter block in the center and fold the corners over it like an envelope. Roll it into a long rectangle, then fold into thirds (like a letter). Chill for 30 minutes.
   Repeat this rolling and folding process three times, chilling for 30 minutes between each turn.
6. Final Roll and Fill
   Roll the laminated dough into a 12×15 inch rectangle. Spread Dijon mustard (if using), then sprinkle evenly with cheese and ham. Roll the dough tightly from the short side into a log.
7. Shape the Loaf
   Place the rolled dough seam-side down into a greased loaf pan lined with parchment. Cover and let it proof at room temperature for 3–4 hours, or until puffy and slightly risen.
8. Egg Wash and Bake
   Preheat the oven to 375°F (190°C). Brush the top with egg wash. Bake for 35–40 minutes, or until deeply golden brown and flaky on top.
9. Cool and Serve
   Allow the loaf to cool for 20 minutes before slicing. Serve warm with a pat of butter or a drizzle of honey for a sweet-savory twist.

Tips for Perfect Results

• Keep Everything Cold: The key to perfect layers is maintaining cold butter during lamination. If the butter starts melting, chill the dough before continuing.
• Don’t Rush the Proof: A slow proof enhances both texture and flavor. You can even refrigerate overnight for a cold proof.
• Customize the Filling: Swap ham for turkey, bacon, or spinach and feta for a vegetarian version.

Serving Suggestions

This loaf is incredibly versatile. Try it:

• Warm, with a fried egg on top for brunch.
• As a sandwich base — just slice, toast, and add fresh tomato or greens.
• Cubed and baked into a savory bread pudding.
• As part of a festive breakfast board with jams and fruit.

Storage & Reheating

Store the cooled loaf in an airtight container for up to 3 days. Reheat slices in a toaster oven at 325°F (160°C) for 5–7 minutes to re-crisp the exterior.
You can also freeze it (whole or sliced) for up to 2 months — just wrap tightly in foil and reheat straight from frozen.

Fun Fact: The Origin of the Croissant Loaf Trend

The hybrid croissant loaf (also known as “croissant bread”) originated in modern artisan bakeries as a way to combine the decadence of croissants with the convenience of a loaf format. The sourdough twist adds a tangy note that balances the butteriness — making it ideal for both sweet and savory adaptations.
