Oat Flour
10.0best for breadMild flavor, similar density
Bread depends on Sorghum Flour for the dough and crumb. Sorghum flour is gluten-free with moderate protein (~8%) and absorbs water steadily; a swap must match that hydration capacity and provide enough structure—through added binders or its own protein—to trap the fermentation gases that leaven the loaf.
Mild flavor, similar density
Oat flour holds 10% less water than sorghum, so drop hydration from 78% to 70% or the dough slackens under shape. Oat's beta-glucan adds a gentle chew the sorghum crumb lacks, so reduce psyllium from 2 teaspoons to 1 1/2 per cup; proof the same 60-75 minutes but score only 1/8 inch deep because oat crust sets thinner.
Not GF but reliable swap
All-purpose flour brings 10-11% gluten that sorghum has zero of, so you can finally knead for a window pane test and skip psyllium entirely. Drop hydration back to 65%, do a full bulk plus second proof, and autolyse 30 minutes — all the steps sorghum forbids. Oven spring climbs roughly 30% and the crumb opens visibly compared to sorghum.
Neutral GF flour swap
Rice flour absorbs about 8% less water than sorghum and has even finer starch, so the crumb trends sandier unless you boost psyllium to 3 teaspoons per cup. Hydrate to 72%, skip autolyse as with sorghum, and shape quickly — rice dough slumps within 20 minutes. Bake 10°F hotter at 460°F to set the crust before the loaf spreads.
Sorghum flour in bread absorbs roughly 15% more water than wheat flour per cup, so hydration must climb from 65% to about 78% or the crumb turns sandy. Because sorghum has zero gluten, you cannot knead for the window pane test — instead, build structure by whisking 2 teaspoons of psyllium husk per cup into the dough and letting it rest 30 minutes before shaping.
Proof once at 80°F for 60-75 minutes; a second proof destroys the fragile starch network and kills oven spring. Score the loaf 1/4 inch deep and bake at 450°F with steam for the first 12 minutes to lock in the crust.
Unlike sorghum flour in pancakes where a thin batter tolerates rapid flip, here the dough must hold shape on a peel without sagging, so a loaf pan is safer than a free-form boule for the first few bakes. Skip autolyse — sorghum lacks the gluten chains that benefit from the rest, and extended hydration turns the dough gummy.
Don't attempt a window pane test on sorghum dough; no gluten means no elastic sheet, and over-kneading only bruises the starch and kills oven spring.
Avoid a second proof at room temperature — sorghum dough's fragile structure collapses on the second rise, producing a dense loaf with no crumb openness.
Skip autolyse entirely; without gluten to benefit, the 30-minute rest only over-hydrates the dough and yields a gummy crust under the bake.
Measure psyllium husk by weight not volume — 2 teaspoons by volume varies by 40% in mass, and under-dosing wrecks hydration so the loaf tears when you score.
Don't skip steam in the first 12 minutes of bake; sorghum needs humid heat for the yeast to lift the dough before the crust sets hard.
