Sourdough Savory Star Bread

Ingredients

Levain (Night Before)

Build this the evening before bake day. It should double and be bubbly by morning.

• 20g (1 tbsp + 1 tsp) active sourdough starter (100% hydration)
• 50g (⅓ cup + 1 tbsp) bread flour
• 50g (3 tbsp + 1 tsp) water (80-85°F / 27-29°C)

The Dough

A soft, enriched dough with milk, butter, and egg. We mix the flour, milk, and levain first to start gluten development before the fat goes in.

• 300g (2⅓ cups) bread flour
• 180g (¾ cup) warm whole milk (100°F / 38°C)
• 120g (½ cup) levain (from above)
• 45g (3 tbsp) unsalted butter, softened
• 50g (1 large) (1 large) large egg, room temperature
• 10g (2 tsp) granulated sugar
• 7g (1¼ tsp) fine sea salt

The Filling

A spanakopita-inspired filling that's creamy, salty, and packed with flavor. The secret is getting every drop of moisture out of the spinach.

• 200g (6 cups (packed)) fresh baby spinach (or frozen, thawed and squeezed dry)
• 120g (1 cup) feta cheese, crumbled
• 80g (¾ cup) low-moisture mozzarella, shredded
• 60g (¼ cup) cream cheese, softened
• 3 cloves (3 cloves) garlic cloves, minced
• 15g (1 tbsp) olive oil
• 2g (½ tsp) red pepper flakes
• 1g (¼ tsp) black pepper, freshly ground
• 2g (¼ tsp) kosher salt

Finish

• 50g (1 large) (1 large) egg, beaten (for egg wash)
• 15g (1 tbsp) whole milk (for egg wash)
• 20g (2 tbsp) black sesame seeds

Total flour: 360g

Hydration: 67%

Pro tip: Total flour is 360g (50g in the levain + 10g from starter + 300g in the final dough). Effective hydration is ~67% when you account for the water content of milk (87%), egg (75%), and butter (15%). The dough should feel soft and smooth, not sticky.

Equipment

Method

Build the Levain

The levain provides the rise and flavor for this enriched dough. Because butter, sugar, and eggs slow down fermentation, we use a moderate inoculation rate to give the starter enough power without over-acidifying the dough.

1. Mix the Levain. In a clean jar or small bowl, combine the starter, flour, and water. Mix until no dry flour remains. Cover loosely and let rest at room temperature (70-75°F / 21-24°C) overnight.
2. Check Readiness. The levain is ready when it has doubled in size, is domed on top, and looks bubbly throughout. A small spoonful should float in water (float test). If your kitchen is cool, this may take up to 12 hours.

Wait: PT10H

Tip: If your kitchen runs cold (below 68°F), use warm water (closer to 85°F) and find a warm spot. The top of the fridge or inside the oven with just the light on works well.

Mix the Dough

We mix the flour, milk, and levain first to start gluten development, then add the enrichments. This order matters. Fat coats flour proteins and prevents gluten from forming, so we want a head start before the butter goes in.

1. Combine Flour, Milk, and Levain. In the bowl of a stand mixer (or a large mixing bowl), combine the bread flour, warm milk, and levain. Mix on low with the dough hook for 2 minutes until a shaggy dough forms. Let rest 20 minutes. This short rest gives the flour time to hydrate before we add the fat.
2. Add Egg, Sugar, and Salt. Add the egg, sugar, and salt. Mix on low for 2 minutes until incorporated, then increase to medium and knead for 5 minutes. The dough should start pulling away from the sides of the bowl.
3. Incorporate Butter. With the mixer on medium-low, add the softened butter one tablespoon at a time. Wait until each piece is mostly absorbed before adding the next. Once all the butter is in, increase to medium and knead for 6-8 minutes until the dough is smooth, elastic, and pulls cleanly from the bowl. It should be soft and slightly tacky but not sticky. By hand: knead on a lightly floured surface for 12-15 minutes total after adding butter.

Tip: The dough will look like a disaster when you first add the butter. That's normal. Keep mixing. It comes together.

Bulk Fermentation

Bulk fermentation for enriched sourdough takes longer than lean doughs. The butter and sugar slow the yeast down, which is actually a good thing. More time means more flavor development.

1. First Rise with Folds. Shape the dough into a ball and place in a lightly greased bowl. Cover with plastic wrap or a damp towel. Perform 3 sets of stretch and fold at 45-minute intervals during the first 2 hours. After the folds, leave the dough undisturbed.
2. Monitor the Rise. Let the dough ferment at room temperature (75-78°F / 24-26°C) until it has risen 60-80% and looks puffy and airy. This typically takes 4-5 hours total (including fold time), but trust the dough, not the clock. In a cool kitchen, it may take 6 hours. Do not wait for doubling. You need this dough rollable, not blown out.

Wait: PT5H

Tip: Don't rush the bulk. Under-fermented enriched dough will be dense and heavy after baking. You want it light and airy before you start rolling it out. But don't overshoot either. This dough needs to be rolled into thin 12-inch circles, so stop at 60-80% rise.

Chill the Dough

Cold dough rolls cleaner and twists sharper. Don't skip this step.

1. Refrigerate Before Shaping. Once bulk fermentation is complete, cover the bowl tightly and refrigerate for 30-45 minutes. You want the dough firm enough to roll thin without sticking, but not so cold that it fights you. The butter in this dough firms up quickly in the fridge, which is exactly what makes shaping easier.

Wait: PT40M

Tip: If your kitchen is above 78°F (26°C), go the full 45 minutes. If it's cooler, 30 minutes is enough.

Make the Filling (During the last hour of bulk fermentation)

Make the filling during the last hour of bulk fermentation so it has time to cool completely. Hot filling will melt into the dough layers and make shaping impossible.

1. Wilt the Spinach. Heat olive oil in a large skillet over medium heat. Add garlic and cook 30 seconds until fragrant. Add spinach in batches, tossing until fully wilted. Season lightly with kosher salt and black pepper.
2. Drain and Chop. Transfer to a colander and press out every bit of moisture. This step matters. Wet filling ruins the layers. Let cool to room temperature, then roughly chop.
3. Combine the Filling. In a bowl, combine the drained spinach, feta, mozzarella, cream cheese, and red pepper flakes. Mix until it holds together as a spreadable paste. Taste and adjust seasoning.

Tip: You want a spreadable paste, not chunky. Too thick and the dough won't twist cleanly. If it feels loose, add a little more cream cheese to bind it.

Shape the Star

Four circles of dough, three layers of filling, 16 cuts, 8 twists. It's easier than it sounds. If your dough feels warm and sticky, pop it back in the fridge for 10 minutes before cutting.

1. Divide the Dough. Turn the dough onto a lightly floured surface. Divide into 4 equal pieces (roughly 150-160g each). Shape each into a ball, cover with a towel, and rest for 10 minutes.
2. Roll the Circles. On a lightly floured surface, roll each piece into a 12-inch circle. They don't need to be perfect, but keep them close to the same size.
3. Stack and Fill. Place the first circle on a parchment-lined baking sheet or round pizza pan. Divide the filling into 3 equal portions. Spread one portion over the first circle, leaving a 1-inch border. Stack the second circle on top. Spread another portion. Repeat with the third circle and remaining filling. Place the fourth circle on top with no filling.
4. Mark the Center. Place a small bowl or glass (about 3 inches wide) in the center of the dough stack and press lightly to mark a circle. Do not cut through. This is your guide for the cuts.
5. Cut the Strips. Using a sharp knife or bench scraper, cut the dough outside the center circle into 16 equal strips. Cut from the edge of the center circle to the outer edge. The easiest way: cut into quarters first, then each quarter in half (8 strips), then each strip in half again (16 strips).
6. Twist the Points. Take two adjacent strips and twist them away from each other (outward) twice, then pinch the ends together to form a point. Repeat around the entire circle until you have 8 points.
7. Remove the Guide. Carefully remove the guide bowl. You should have a sunflower-star shape with a clear center and 8 twisted points.

Tip: Work quickly once you start the assembly so the layers don't stick together before you cut. If the dough softens up too much during shaping, pop the whole assembly back in the fridge for 10 minutes before cutting.

Proof and Bake

The star shape has a lot of surface area, so it proofs faster than you might expect. Don't walk away for two hours. Check it at 30 minutes.

1. Final Proof. Cover loosely with plastic wrap and let proof for 30-45 minutes until slightly puffed. Because sourdough moves slower than instant yeast, you may need up to 60 minutes. The dough should look relaxed and pillowy, not dramatically risen.
2. Preheat. Preheat your oven to 375°F (190°C) with a rack in the center position.
3. Egg Wash. Whisk the egg and milk together for the egg wash. Brush gently over the entire surface of the star, getting into the twists.
4. Add Sesame Seeds. Scatter black sesame seeds over the center circle only. This creates a dramatic contrast against the golden egg-washed dough.
5. Bake. Bake for 25-30 minutes until deep golden brown. The layers should be set and the filling visible between the twists. If the top is browning too fast, tent loosely with foil after 20 minutes.
6. Cool and Serve. Let cool on the pan for 15 minutes before serving. Pull-apart style, right from the center. The cheese should still be warm and stretchy.

Wait: PT45M

Shape the Star

Four circles of dough, three layers of filling, 16 cuts, 8 twists.

Star Bread (recommended)

The classic pull-apart star shape with visible filling between the twisted points.

1. Divide. Cut dough into 4 equal pieces (~150-160g each). Shape into balls, rest 10 minutes covered.
2. Roll. Roll each piece into a 12-inch circle on a lightly floured surface.
3. Stack and Fill. Layer: dough, filling, dough, filling, dough, filling, dough (no filling on top). Leave 1-inch border on each filling layer.
4. Mark Center. Press a 3-inch bowl or glass into the center to mark (don't cut through).
5. Cut 16 Strips. Cut from center circle to outer edge: quarters first, then halves of each quarter, then halves again.
6. Twist. Take 2 adjacent strips, twist outward twice, pinch ends together. Repeat for 8 points.

Proof test: After shaping, the star should proof 30-45 minutes (up to 60 for sourdough) until slightly puffed. The dough between the twists should look relaxed and pillowy. Don't wait for it to double. The star shape has so much surface area that it proofs faster than you'd expect.

Bake

Enriched sourdough breads bake at a moderate temperature. The milk proteins and sugar promote browning, so watch closely after 20 minutes.

Oven: 190°C / 375°F. Internal temperature when done: 88°C / 190°F.

Standard Oven (recommended)

Bake on a parchment-lined baking sheet or round pizza pan.

Equipment: Parchment-lined baking sheet or round pizza pan

1. Preheat. Preheat oven to 375°F (190°C) with a rack in the center position.
2. Egg Wash. Brush entire surface with egg wash (1 egg + 1 tbsp milk). Get into the twists.
3. Sesame Seeds. Scatter black sesame seeds over the center circle only.
4. Bake. Bake 25-30 minutes until deep golden brown. Filling should be bubbling between the twists. Tent with foil if browning too fast after 20 minutes.
5. Cool. Let cool on the pan for 15 minutes. Serve pull-apart style.

Storage

• Room temperature: 2-3 days wrapped in foil or stored in an airtight container
• Refrigerated: Up to 5 days. Reheat uncovered at 325°F (163°C) for 10 minutes.
• Frozen: Up to 2 months. Wrap tightly in plastic wrap and foil. Thaw overnight in the fridge, then reheat.
• Refresh: Warm at 325°F (163°C) for 10-12 minutes until the cheese is melty again.

Frequently Asked Questions

Why didn't my star bread hold its shape?

Two common reasons: the dough was too warm and soft (refrigerate for 15-20 minutes before shaping), or the filling was too wet. Squeeze every drop of liquid from the spinach before mixing the filling.

Can I use frozen spinach instead of fresh?

Yes. Thaw completely, then wring it out in a clean kitchen towel until barely damp. You'll need about 100g of frozen spinach to replace 200g of fresh.

Can I substitute the feta?

Ricotta salata or goat cheese work well. Keep it crumbled, not wet. Avoid wet ricotta, which adds too much moisture.

Can I make this ahead?

Yes. Assemble the star through the shaping step, cover tightly, and refrigerate overnight. Pull it out 30-45 minutes before baking to take the chill off, then egg wash and bake as directed. The cold retard will actually improve the sourdough flavor.

How do I cut the 16 strips evenly?

First cut the dough into quarters. Then cut each quarter in half to get 8 strips. Then cut each of those in half to get 16. This systematic approach keeps everything even.

Can I skip the black sesame seeds?

White sesame seeds, everything bagel seasoning, or flaky sea salt all look great on the center. The seeds are for visual impact, not structural.

My bulk fermentation is taking forever. Is that normal?

Enriched sourdough doughs ferment slowly. Butter, sugar, and eggs all slow things down. At 75°F, expect 4-5 hours. Below 70°F, you could be looking at 6-7 hours. Trust the visual cues (60-80% rise, puffy and airy) over the clock.

What's the difference between this and the yeasted version?

The sourdough version uses a levain instead of instant yeast, takes longer to ferment, and develops a more complex, slightly tangy flavor that pairs beautifully with the salty spanakopita filling. The shaping, filling, and baking are identical.
