This gluten-free sourdough loaf uses coconut flour blended with starches and psyllium to mimic crumb structure while remaining dairy- and grain-free. Low in volume but very moist; the long fermentation improves flavor and digestibility by lowering pH and breaking down some polysaccharides [1][2].

Ingredients

Weigh all ingredients on a kitchen scale. Gluten-free flours and starches varyโ€”accuracy matters for hydration and texture [1].

Ingredient Amount % Note
Coconut flour 140g 28% Absorbent โ€” measure by weight
Tapioca starch (or arrowroot) 200g 40% Provides chew and extensibility
Brown rice flour 80g 16% Adds body and mild flavor
Water 420g 84% Warm (25-30ยฐC) to hydrate coconut flour
Active gluten-free sourdough starter 120g 24% Feed with brown rice/tapioca mix prior to use; active and bubbly [1]
Psyllium husk powder 20g 4% Key binder for structure
Salt 9g 1.8% Adjust to taste
Olive oil or melted coconut oil 20g 4% Keeps crumb tender
Honey or maple syrup (optional) 15g 3% Feeds starter and promotes browning

Schedule

Weekend Version

Easy paced schedule so flavors develop

Friday 8pm Feed gluten-free starter (use same flours/starches)
Saturday 8am Mix dough (20 min)
Saturday 8:30am-12:30pm Bulk rest at room temp (fold once at 30โ€“45 min)
Saturday 12:30pm Shape into loaf (10 min)
Saturday 1-4pm Final proof at room temp or 12โ€“14h in fridge
Saturday 4pm Bake (50-65 min)

Weekday Version

Mix at night, bake next evening

Evening 10pm Feed starter
Evening 11pm Mix dough and shape, then fridge proof
Next day 5pm Preheat oven with [Dutch oven](https://amzn.to/4sVhKhN)
Next day 6pm Bake (50-65 min)

๐Ÿ’ก Tips

  • If dough looks overproofed (very slack, collapsed) โ†’ shorten proof time or cooler temp next time [1]
  • Fridge slows fermentation โ€” shaped loaves keep 24โ€“48h refrigerated without major flavor loss [2]

Step by Step

1

Prepare starter and mise en place

Ensure your gluten-free starter is active and bubbly. Have all flours weighed and psyllium measured. Use a glass jar for starter to confirm rise. Warm water slightly to help coconut flour hydrate [1].

โœ“ Visual check: Starter doubled or clearly bubbly 4โ€“8 hours after feeding
โš ๏ธ Common mistake: Using an inactive starter โ†’ weak rise and poor flavor

โฑ 5-15 minutes

2

Mix dry and wet separately, then combine

Whisk coconut flour, tapioca starch, brown rice flour, psyllium, and salt in a large mixing bowl. Mix water, starter, oil, and honey in another container. Pour liquids into dry and stir with a dough scraper or spatula until homogeneous. Let rest 10โ€“20 minutes to allow psyllium and coconut flour to absorb water fully [2][1].

โœ“ Visual check: Thick batter-like dough that holds shape but is slightly elastic
โš ๏ธ Common mistake: Adding extra flour before hydration โ†’ leads to dry crumb

โฑ 15 minutes

3

Bulk rest and folds

Cover the bowl with a lid, plastic, or a damp towel. At 30โ€“45 minutes, perform one gentle fold: pull a portion from the edge and fold into center to even out hydration. Repeat once after another 30โ€“45 minutes if dough benefits. Gluten-free dough doesn't develop gluten but folding improves homogeneity [2].

โœ“ Visual check: More cohesive surface, fewer dry pockets

โฑ 1โ€“4 hours depending on temp

4

Shape

Dust work surface or parchment with tapioca starch. Turn dough out with a dough scraper โ€” it will be batter-like but foldable. Shape into a tight oblong or place directly into a floured loaf pan. For free-form, place into a floured banneton or lined bowl. Cover and chill if using overnight proof.

โœ“ Visual check: Loaf holds shape on parchment or in pan

โฑ 10 minutes

5

Final proof

Proof at room temperature until visibly puffed (not doubled). Alternatively proof in the fridge for 12โ€“18 hours โ€” cold proof improves flavor and handling [1][2].

โœ“ Visual check: Surface slightly domed and jiggles gently when moved

โฑ 1โ€“4 hours at room temp or 12โ€“18 hours in fridge

6

Bake

Preheat oven to 450ยฐF/230ยฐC with the Dutch oven inside for 30 min. Transfer loaf on parchment paper, score with a bread lame or knife, and place into Dutch oven. Bake 20โ€“25 min with lid, then remove lid and bake 20โ€“30 min more until crust deepens. Internal temp target: 205ยฐF/96ยฐC. Using an instant-read thermometer gives reliable doneness [1].

โœ“ Visual check: Crust golden to deep brown; loaf sounds hollow when tapped

โฑ 40โ€“55 minutes

7

Cool

Remove from oven with oven mitts and cool on a rack for at least 2 hours. Cooling stabilizes crumb; cutting earlier yields gummy texture. For gluten-free breads, full cooling is even more important because starches finish setting as they cool [2][1].

โœ“ Visual check: Loaf no longer warm and sliceable without gumming

โฑ 2+ hours

Tips & Variations

Variations

Seeded coconut loaf

Fold in 60g mixed seeds (sunflower, pumpkin)

โ†’ Adds crunch and flavor

Herbed

Add 1 tbsp dried rosemary and 1 tsp garlic powder

โ†’ Savory loaf for sandwiches

Lower-fat

Omit oil and increase water by 15g

โ†’ Slightly denser, less tender crumb

Pro Tips

  • ๐Ÿ’ก Always weigh ingredients with a digital kitchen scale โ€” small errors change hydration dramatically [1]
  • ๐Ÿ’ก If converting a wheat starter, refresh it on gluten-free flours for 3โ€“5 feedings to avoid off-flavors [2]

Common Issues

Not going as planned? Common issues:

Storage

Airtight bread bag or box

4-6 days

Store at room temp; cut side down retains moisture

Kitchen towel

2-3 days

Use linen to avoid excess drying

Freezing

3 months

Slice and freeze; reheat slices directly from frozen

โš ๏ธ Avoid refrigeration โ€” it accelerates staling through starch retrogradation [2][1]
