Ingredient Breakdown
- 6 grams sourdough starter
- 60 grams all-purpose or bread flour (about ½ cup)
- 60 grams of water (about ¼ cup)
- 120 grams of levain
- 340 grams of water (about 1 cup plus 6 Tablespoons)
- 10 grams of salt (about 1½ teaspoons)
- 500 grams of bread flour (about 3½ cups)
- 113 grams unsalted butter (about ½ cup)
- 175 grams shredded Gruyère cheese
- 150 grams diced ham
How to Make Ham and Cheese Sourdough Croissant Loaf
Step 1: Prepare the Levain
Start by mixing your sourdough starter with all-purpose flour and water in a small bowl. Let it sit for about 10-12 hours at a temperature of 78-80°F. You want it bubbly and frothy, this is the magic that gives the loaf its rise!
Step 2: Mix the Dough
In a large bowl, combine your ripe levain with 340 grams of water, salt, and 500 grams of bread flour. Stir it up until you get a wet, sticky dough that feels kinda like a doughy dream! Cover it and let it rest for 30 minutes. This resting period will help hydrate the flour.
Step 3: Stretch and Fold
Now for some fun! For the next 1½ hours, perform a series of stretch and folds every 30 minutes. Simply grab a corner of the dough, stretch it up, and fold it over to the center. This helps develop the gluten, which gives you that amazing chewy texture.
Step 4: Incorporate Butter
After your stretches, it’s time to incorporate the cold butter (about 113 grams) into the dough. I like to flatten it out a bit, then fold it in like an envelope. Make sure it’s all mixed well, and then allow the dough to rise for about 6-7 hours until it’s around 70% risen with some lovely bubbles visible.
Step 5: Shape the Dough
Once the dough has risen, take it out and stretch it into a rectangle on a lightly floured surface. Layer on the 150 grams of shredded Gruyère cheese and the diced ham. Fold the dough over to encase the filling and roll it up to create your loaf.
Step 6: Cold Fermentation
Cover the shaped dough and pop it in the fridge overnight or for up to 12-18 hours. (This is a great time to clean out your fridge if you need to!)
Step 7: Preheat the Dutch Oven
Preheat your Dutch oven to 450°F for about 20 minutes. This will give your loaf the nice, crispy crust we’re all craving!
Step 8: Score and Bake
Score the dough with a sharp knife or bread lame. Sprinkle the reserved 25 grams of cheese on top, then place it carefully in the preheated Dutch oven. Bake it covered for 25 minutes, and then uncover it and bake for an additional 20 minutes at 425°F until it’s golden brown and baked through.
Step 9: Cool and Serve
Once out of the oven, let your beautiful loaf cool on a baking rack before digging in. It’ll be tempting to slice it immediately, but trust me on this one, allowing it to cool gives you better slices and less mess!
I can guarantee you’ll love the flaky layers, the warm, gooey cheese, and the salty ham oozing into every bite.
