Steel-cut work best, similar hearty texture

barley substitute
for baking.
Barley flour contributes beta-glucan gums and about 5-8% gluten (hordein), giving baked goods a tender, slightly dense crumb rather than the open windowpane of wheat. In loaves it caps rise near 70% of a bread-flour control because the gluten network is weaker; in quick breads and cookies that matters less. This page ranks swaps by crumb structure first, oven-spring behavior at 375-425 degrees F second, and nutty malt character third.

adjustment for baking
Oat flour brings no gluten and roughly 4% beta-glucan — higher than barley — so baked crumb gets moister but rises 15-20% less. Steel-cut as a whole-grain inclusion adds chew. Use 1:1 by volume; add 1 teaspoon vital wheat gluten per cup to compensate, and drop oven temperature by 15 degrees to avoid over-browning from oat sugars.
02
Farro
10.0best for baking1 cup : 1 cup
Closest chewy texture and nuttiness
10.0
adjustment for baking
Farro flour carries 10-12% gluten from ancient wheat, enough to push oven-spring 25% higher than barley in the same loaf. Cracked farro folded in at 20% of dry weight gives a hearty chew without blocking rise. Swap 1:1; hydrate dough 5% more because farro drinks slower, and bake at 425 degrees F for crust set.
03
Spelt
10.0best for baking1 cup : 1 cup
Closest texture and cook time; mildly nutty with slight sweetness, works in pilafs and risotto-style dishes
10.0
adjustment for baking
Spelt has 11% gluten but it's fragile — over-kneading past 4 minutes tears the network and the loaf collapses. It matches barley's mildly sweet, nutty note, slightly malted. Use 1:1 flour-for-flour, cut kneading time in half versus a wheat recipe, and bake at 400 degrees F to set crumb before the weak gluten gives out.

Quinoa
6.71 cup : 1 cup
Cooks faster, gluten-free alternative
6.7
adjustment for this dish
Quinoa flour is gluten-free and bitter from residual saponin unless rinsed pre-grind; its starch sets at 149 degrees F, lower than wheat, so crumb firms early. Use 1:1 by volume paired with 1 teaspoon psyllium husk per cup to replace structure. Expect a denser loaf and about 30% less rise than a barley control.
05
Brown Rice
10.01 cup : 1 cup
Similar chewy texture and nutty flavor
10.0
adjustment for this dish
Brown rice flour has 0% gluten, gritty mouthfeel unless milled under 150 microns, and browns quickly because of surface bran oils. It matches barley's nutty register. Use 1:1 with 1/4 teaspoon xanthan gum per cup to hold structure, and tent with foil after 20 minutes to keep crust from darkening past medium brown.
06
Triticale
10.01 cup : 1 cup
Hearty texture, easy to find
10.0
adjustment for this dish
Triticale is a rye-wheat hybrid with 8-10% gluten — almost identical to barley in bake behavior, with a rye-leaning tang. Use 1:1 flour-for-flour. Kneading tolerance is low like rye, so mix just until the dough holds; ferment 90 minutes at 75 degrees F and bake at 415 degrees F to keep crumb open.
07
White Rice
6.71 cup : 1 cup
Milder and softer, works in soups and stews
6.7
adjustment for this dish
White rice flour is gluten-free, nearly flavorless, and sets into a tight, slightly gummy crumb unless paired with starch-breakers like sugar above 15% of flour weight. Use 1:1 with 1/4 teaspoon xanthan per cup. Bake 5-10 minutes longer at the same 400 degrees F because center hydration lingers longer than barley dough.
08
Couscous
10.01 cup : 1 cup
Chewier texture, works in salads and pilafs
10.0
adjustment for this dish
Couscous is pre-steamed semolina, not flour — ground fine it acts like a coarse durum meal with 12% gluten. Use 1:1 by volume but pulse in a food processor to sub-100 micron particle size first. Hydrate 10% more than barley flour; bake at 400 degrees F and expect a crunchier crust from the hard wheat endosperm.
