This is a rustic wheat (Weizen) sourdough loaf studded with toasted hazelnuts. The method uses an extended autolyse and controlled bulk fermentation to build gluten without heavy kneading; nuts are toasted and folded in late to preserve structure and aroma. Toasting the nuts increases flavor and reduces bitterness; keeping nut inclusion around 10–15% prevents weakening the dough from excess oils and particulates.[1][2][6]

✓ High flavor from toasted hazelnuts ✓ Autolyse + stretch-and-folds for strength ✓ Option for overnight cold proof

Ingredients

Weigh all ingredients on a kitchen scale. Use the percentages to scale the formula; keep hazelnuts at or below 15% of flour weight to avoid slack dough.[6][4]

Ingredient Amount % Note
Bread flour (Wheat) 500g 100% Type 550 / strong wheat flour
Water 360g 72% Adjust ±10g if flour hydration varies
Active wheat sourdough starter 120g 24% Peak activity, fed 4-8 hours earlier
Salt 10g 2% Fine sea salt
Hazelnuts (skin-on or skinned) 75g 15% Roasted and roughly chopped

Schedule

Weekend Version

Relaxed schedule with daytime bulk fermentation and same-day bake

08:00 Feed starter (if needed so it's active by midday)
11:00 Mix flour and water for autolyse (15 min)
11:15 Add starter and salt, mix to combine (10 min)
11:25-14:30 Bulk fermentation with 3 sets of stretch-and-folds (every 30–40 min) (3 h)
14:30 Fold in toasted hazelnuts gently
14:45 Pre-shape and bench rest (15 min)
15:00-16:30 Final shaping; proof at room temp or in banneton
16:45 Bake in preheated [Dutch oven](https://amzn.to/4sVhKhN) (50–60 min)

Weekday Version (Night + Day)

Mix and shape in the evening, cold retard overnight; bake next day

21:00 (Evening) Mix, autolyse, bulk ferment for 2–3 hours
23:30 Pre-shape, final shape into banneton, refrigerate (cold retard)
Next day 16:00 Remove from fridge to warm slightly, preheat oven
16:45 Bake (50–60 min)

💡 Tips

  • If dough feels slack after adding nuts, gently tighten with brief coil folds rather than adding flour; nuts release oil that weakens gluten[6].
  • If fermentation is faster than planned, cold retard in the fridge to preserve structure and flavor[2][4].

Step by Step

1

Toast and prepare hazelnuts

Spread hazelnuts on a baking tray and roast at 150°C / 300°F for 8–12 minutes until fragrant, then cool and roughly chop. Toasting increases aroma and reduces bitterness from skins[1][2].

✓ Visual check: Nuts golden-brown and aromatic
⚠️ Common mistake: Overtoasting → bitter flavor

⏱ 15 minutes

2

Autolyse

In a large mixing bowl combine flour and 90% of water; mix until no dry flour remains. Rest 20–60 minutes. Autolyse develops gluten without mechanical mixing and improves extensibility[6][4].

✓ Visual check: Smooth surface, slightly tacky dough
💡 Reserve a little water to help incorporate salt and starter

⏱ 20–60 minutes

3

Add starter and salt

Add starter and remaining water, then salt. Mix with a dough whisk or by hand until incorporated; dough should be cohesive but sticky. Let rest 10 minutes and perform first set of stretch-and-folds.

✓ Visual check: Dough comes together into a mass with visible bubbles forming
⚠️ Common mistake: Adding all nuts now → oils can coat gluten and reduce strength, add later[6]

⏱ 10 minutes

4

Build strength with stretch-and-folds

Perform 3–4 sets of coil or stretch-and-folds every 30–40 minutes during bulk. Use a dough scraper to help lift and fold. This method develops structure in high-hydration wheat dough without kneading[4][1].

✓ Visual check: Dough becomes smoother, holds shape better, bubbles visible

⏱ 2–3 hours (total bulk)

5

Incorporate hazelnuts

After the dough has gained strength (mid-late bulk), sprinkle chopped hazelnuts on top and incorporate with gentle folds or lamination so they are evenly distributed without tearing the gluten network.[3][6]

✓ Visual check: Nuts dispersed but dough still cohesive
💡 If nuts feel oily, reduce quantity next time to 10% for a tighter crumb

⏱ 5 minutes

6

Pre-shape and bench rest

Turn dough onto lightly floured surface. Pre-shape gently into a loose boule or bâtard, rest 15–20 minutes to relax the dough.

✓ Visual check: Dough relaxes and spreads slightly

⏱ 15–20 minutes

7

Final shape and proof

Shape to create surface tension and place seam-side up in a floured banneton or lined bowl. Proof at room temperature until nearly doubled, or refrigerate 12–18 hours for cold proof which improves flavor and makes handling easier.[2][4]

✓ Visual check: Loaf holds shape, poke test springs back slowly

⏱ 1–3 hours (room) or 12–18 hours (fridge)

8

Bake

Preheat oven to 250°C / 480°F with the Dutch oven inside for 30–45 minutes. Turn loaf onto parchment paper, score with a bread lame and transfer into the preheated pot. Bake covered 15–20 minutes, then uncover and reduce to 200°C / 400°F for another 25–35 minutes until crust is deep golden and internal temperature is 96–98°C / 205–208°F measured with an instant-read thermometer.[4][7]

✓ Visual check: Strong oven spring, well caramelized crust, hollow sound when tapped

⏱ 45–55 minutes

9

Cool

Remove loaf and cool on a wire rack for at least 2 hours before slicing. Cooling allows residual starches to set; slicing too early yields gummy crumb.[2][7]

✓ Visual check: Loaf cool to room temperature

⏱ 2+ hours

Tips & Variations

Variations

More aromatic (honey + buttered nuts)

Brush chopped nuts with 1 tsp honey before folding in

→ Adds a touch of sweetness and deeper caramelization

Seed & nut mix

Replace half of the hazelnuts with 50g mixed seeds

→ Adds texture and extends crunch

Lower hydration

Reduce water to 340–350g (68–70% hydration)

→ Easier handling, tighter crumb

Pro Tips

  • 💡 Weigh nuts after toasting — toasting reduces weight slightly but not volume[1].
  • 💡 If dough feels slack after adding nuts, perform short coil folds and rest rather than adding flour; oil from nuts, not hydration, often causes slackness[6].
  • 💡 Use a dough scraper to help lift dough during folds and to incorporate inclusions gently.

Common Issues

If things go wrong, these focused solutions address common problems when baking nut breads:

Storage

Paper bag / bread bag

3–4 days

Keep cut side down; crust stays crisp

Cloth-wrapped

4–6 days

Wrap in linen or cotton to balance moisture

Freezing

3 months

Slice and flash-freeze on tray, then bag; toast slices from frozen

⚠️ Avoid fridge storage — it accelerates staling due to starch retrogradation[8]
