This rustic baguette-style sourdough milk bread combines the soft crumb of shokupan with the structure of a baguette. It’s naturally leavened, lightly sweet, includes a portion of whole wheat flour, and proofed in 15-inch baguette banneton baskets. It’s perfect for sandwich slicing or serving warm with butter.
I came up with this recipe while chasing a specific loaf I couldn’t quite find: something naturally leavened and soft enough for sandwiches, but shaped like a baguette for a little rustic charm.
I didn’t want the crisp crust or airy structure of a traditional baguette, just something that would hold its shape while staying sliceable and satisfying. By combining a mild sourdough levain with the yudane method, I landed on this Baguette-Style Sourdough Milk Bread (Rustic & Soft-Crumb Loaf).
Why Shape Milk Bread Like a Baguette?
Shaping this naturally leavened milk bread into a long, slender loaf gives it a unique look, but it’s more than just visual appeal. Here’s why I love using a baguette-style shape for this soft dough:
- It fits perfectly in a 15-inch baguette proofing basket, which supports the dough and helps it hold its shape without spreading flat.
- Each slice has a nice balance of crust and crumb – more crust than a traditional pullman loaf, but still soft and tender.
- The long, narrow profile makes beautiful sandwich slices, especially for open-faced toasts, small tea sandwiches, or picnic-style lunches.
- It bakes evenly and quickly, thanks to its slender form – perfect if you don’t want to wait for a big, tall loaf to finish baking.
- It’s just plain fun – a cozy, rustic twist on traditional milk bread that slices like a baguette but eats like a soft sandwich loaf.
Tips from My Test Bakes
I tested several variations of this recipe to dial in the texture and flavor, and a few small details made a big difference in the final loaf. Here’s what I learned along the way:
1. Use Fresh Ingredients, Especially the Butter
Because this bread is so gently flavored, ingredient freshness matters. I learned this the hard way when a loaf made with butter that had been left out too long developed an off flavor. Stick with sweet-smelling, clean-tasting butter, fresh milk, and recently milled flour.
2. Whole Milk vs. Non-Dairy Milk
I tested a batch with oat milk, and while the loaf still turned out well, the crumb wasn’t quite as soft as the one made with whole dairy milk.
Tip: If you’re using oat milk or another plant-based milk, increase the butter slightly, from 30g to 35-40g, to help restore softness and richness in the crumb.
3. Bake Gently for a Soft Crust
This isn’t your typical artisan baguette, so it doesn’t need the blazing heat or a baking stone. I found that baking at a lower temperature (around 375°F) helped maintain a tender crust without compromising oven spring. I also used a bit of steam in the first few minutes of baking, which gave the loaves just enough lift and a beautiful shape without toughening the exterior.
Skip the baking stone for this one — a simple baking sheet or parchment-lined tray works best to avoid over-crusting.
What Is the Yudane Method and Why Use It?
- A pre-cooked flour paste made with boiling water
- Locks in moisture and improves softness
- Slows staling and enhances elasticity — ideal for sandwich-style loaves
- Works beautifully with sourdough for a balanced, naturally leavened texture
Shaping Tips for Baguette-Style Loaves
- Divide the dough into two equal pieces after bulk fermentation
- Gently degas and pre-shape into logs
- Final shape: roll each piece into a tight 14-inch log
- Tuck ends slightly so they rest neatly in your 15-inch baguette proofing basket
- Seam side up in the basket, so it bakes seam side down for a smooth top
- Use a light dusting of rice flour or a flour-lined cotton liner to prevent sticking
Serving Suggestions
- Sliced and toasted with jam or honey butter
- Makes excellent sandwich bread — try egg salad, cucumber, or ham & cheese
- French toast the next day
- Slice in half or thirds for picnic sandwiches
- Pairs well with soups, stews, or butter boards
Timeline At-A-Glance
- Night before: Make yudane and levain
- Morning: Mix dough, bulk ferment (4–5 hours), shape
- Final proof: 2–3 hours at room temp or overnight in fridge
- Bake: ~25 minutes at 375°F

Rustic Baguette-Style Sourdough Milk Bread

Description
This rustic baguette-style sourdough milk bread combines the soft crumb of shokupan with the structure of a baguette.
Ingredients
Yudane
- 75g (~1/2 + 2 Tbsp.) all-purpose or whole wheat flour
- 100g (scant 1/2 cup) boiling water
Levain
- 20g (~ 1 Tbsp.) mature sourdough starter (100% hydration)
- 40g (~ 2 Tbsp. + 2 tsp.) water
- 40g (~ 1/3 cup) all-purpose flour or whole wheat flour
Main Dough
- All of the yudane (from above)
- All of the levain (from above)
- 120g-170g (~1/2 cup to 2/3 cup + 1 Tbsp.) milk (cold or room temp), dairy or plant-based *See note*
- 360g (~3 cups) all-purpose flour
- 15 g (2 Tbsp.) ground flaxseed or 1 large egg (50g)
- 40g (~ 3 Tbsp.) sugar
- 25g-50g (~1 Tbsp. + 2 tsp. to 3 Tbsp. + 1 tsp.) water, as needed
- 8g (1 1/4 tsp.) fine sea salt
- 30g-40g (2–3 Tbsp.) unsalted butter, softened *See note*
- 1/2 cup boiling water for steam pan
Instructions
Yudane (Prepare the Night Before)
Mix flour and boiling water until fully hydrated and sticky. Let cool, then cover and refrigerate overnight (8–16 hours). Bring the paste to room temperature before mixing the dough.
Levain (Mix Night Before, ~8-12 hrs before dough)
In a small bowl, mix levain ingredients. Ferment overnight at 70-75°F until expanded and bubbly.
Mix & Autolyse
In a large bowl, add the yudane flour paste and levain. Pour in 120 grams of milk and whisk to combine. Add the flour, flaxseed meal, and sugar. Mix thoroughly until no dry flour remains, adding additional milk or water as needed. Cover and let rest 30-45 minutes.
2. Add Salt & Butter
Sprinkle the salt over the top of the dough. Using wet fingers, squish and knead the dough until the salt is fully incorporated into the dough. Add sprinkles of water as needed. Let rest 15-20 minutes.
When the dough is moderately developed, begin adding the butter in small chunks. Fold and knead until the dough is smooth, supple, and elastic. Dough will be soft and slightly tacky, but not sticky.
3. Bulk Fermentation (3.5-4.5 hours at 75-78°F)
- Stretch and fold every 30-45 minutes (2-3 rounds total)
- Bulk until dough is soft, puffy, and ~60-75% risen
Optional: Cold retard the dough overnight after bulk for added flavor
4. Divide & Shape
Divide into 2 equal pieces (~450g each). Lightly degas, then shape each piece into a 15-inch log. Place the shaped loaves seam side up in lined and lightly floured baguette bannetons.
5. Final Proof
- Room Temp: 2-3 hours at 75-78°F
- Or Cold Proof: 8-12 hours in fridge
Proof until the dough springs back slowly when pressed and feels aerated.
6. Bake
- Preheat oven to 375°F (190°C) with a rack in the middle of the oven and a steam pan underneath.
- Gently turn out loaves seam side down onto a baking sheet lined with parchment.
- Brush with milk or egg wash for color and shine; alternately, brush with butter after baking.
- Place the loaves (on the baking sheet) in the oven, pour 1/2 cup boiling water in the steam pan, and immediately close the door.
- Bake 22-26 minutes until golden and internal temp is ~190°F. Rotate the loaves partway through baking for even baking.
Notes
Dairy vs plant-based milk: We found that plant-based milk works; however, it doesn’t have the same richness — unless you sneak in a little extra butter.
When using plant-based milk, increase the butter slightly, from 30g to 35-40g, to help restore softness and richness in the crumb.
