Rustic Sourdough Recipe

Makes 1 Large Loaf

Prep and Cook Time 1 Hour + Standing and Cooling Time


4⅔ cups (700g) organic white bread flour

1½ cups (240g) organic wholemeal plain flour

1½ tablespoons sea salt flakes

480ml filtered or bottled water, approximately

Organic bread flour, extra

Sourdough Starter Ingredients (Makes 3 Cups)

3 teaspoons (10g) dried yeast

1½ teaspoons caster sugar

2 cups (500ml) lukewarm filtered or bottled water

2⅔ cups (350g) organic bread flour

Rustic Sourdough recipe


1) Sourdough Starter: Place yeast, sugar and the water in a large bowl; stir until yeast dissolves. Cover; stand in a warm place for 10 minutes or until frothy. Add sifted flour; stir to combine. Cover; stand at room temperature for 2 days. After 2 days, the starter should have a pleasant mild sour smell and small bubbles on the surface, a sign that it’s active. Sourdough starter will keep indefinitely in the fridge, adding ¾ cup (165g) organic white flour and ¾ cup water each week after using. If not making bread, dispose of 1½ cups of starter before adding extra flour and water. If using daily, leave at room temperature, adding amounts above each day.

2) On Day 3, place 4 cups (600g) of bread flour, the wholemeal flour, salt, 1½ cups of the Sourdough Starter and the water in a large bowl of an electric mixer fitted with a dough hook. Knead on low speed for 10 minutes, until you have a soft, sticky dough. Slowly add remaining flour until well incorporated (The mixture is quite wet at the beginning of mixing but becomes a soft dough by the end.)

3) Transfer dough to an oiled large bowl; cover with cling film. Stand at room temperature for 4-6 hours or until doubled. Meanwhile, spray a cane proving basket (about 30cm wide, 9cm high) lightly with water; dust with extra flour, rotating and tapping to cover all surfaces. Tap out excess; set aside to dry.

4) Line a large baking tray with baking paper. Turn dough onto a lightly floured surface. Lightly pull each of the 4 sides of the dough from the outside edge to the centre of top to stretch outside skin of the dough. Repeat with 4 diagonals; transfer to proving basket, with seam up. Wrap in cling film, prove in refrigerator for 12 hours or overnight. Remove from refrigerator and bring to room temperature (2-3 hours).

5) When close to room temperature, preheat oven to 240°C, Miele Moisture Plus with 2 bursts of steam. Place baking paper-lined tray on top of proving basket. With the baking paper between the dough and tray, invert dough onto tray; lift off proving basket. Cut 4 slashes into bread in a square shape using a box knife or scalpel.

6) Bake bread on shelf 2 for 30 minutes, or until golden brown and sounding hollow when tapped. Transfer to a wire rack until cool.

Chef’s Notes

Suitable to freeze. Not suitable to microwave.

For Conventional Cooking: Preheat oven to 240°C. Place a small shallow-sided oven tray on the lowest shelf of the oven when preheating. Add 10 ice-cubes to preheated oven tray and bake bread for 30 minutes or until golden brown and sounding hollow when tapped. Transfer to a wire rack until cool.

For a Garlic and Rosemary Variation on the Recipe

Wrap 1 bulb of garlic in foil; roast at 200°C for 30 minutes or until soft. Peel garlic and fold through dough with ¼ cup chopped rosemary leaves after mixing. You will need to begin this recipe 3 days ahead.
