Ingredients for 100 barley bread

Five simple ingredients transform into artisanal-style barley bread with nutty depth and chewy texture.

Barley flour is the star here—Bob’s Red Mill or King Arthur are my go-tos, but any 100% whole grain will work. Freshly ground flour gives the best texture, but store-bought bags are fine if labeled ‘whole grain.’ The yeast needs to be active, so toss it in warm water with honey for 5 minutes—it should foam up like a beer. If it doesn’t, your yeast is dead and needs replacing. King Arthur sells it in bulk, which is perfect for frequent bakers. For the honey, any variety works, but raw, local honey adds subtle floral notes that pair beautifully with the barley’s nuttiness.

No barley flour? Substitute with a mix of whole wheat and rye flour at a 50/50 ratio—it won’t be identical, but you’ll still get a hearty loaf. Running short on honey? Maple syrup or agave work in a pinch, though the flavor will shift slightly. Olive oil can be swapped for vegetable or canola oil, but you’ll lose some of that fruity depth. The ice water is key for adjusting the dough’s stickiness—add it gradually if your kitchen’s humid. For a sweeter loaf, add seeds like sesame or flax to the dough before baking.

This dough needs time to rise—at least 2 hours at room temperature, or overnight in the fridge for deeper flavor. Shape it gently to avoid overworking the gluten, which can make the crumb tough. Bake until golden and internal temp hits 205°F. Cool completely before slicing, or the bread will turn gummy. Wrapped in a clean towel, it stays fresh for 5 days at room temp. For longer storage, freeze slices—3 months is no problem. The crust gets even more flavorful as it cools, so patience pays off.

Step-by-step instructions for 100-Grain barley bread

Here’s how to transform barley flour into a rustic loaf with perfect rise and nutty depth.

In a large mixing bowl, combine the 2 cups warm water (between 105-110°F) with the 2 tablespoons honey and 1 tablespoon active dry yeast. Let this mixture sit for 5-10 minutes until it becomes frothy—this confirms the yeast is alive and ready to work. You’ll see bubbles forming and a light, airy texture developing.

If no bubbles appear after 10 minutes, your yeast may be inactive. Discard the mixture and start fresh with a new packet of yeast—this is crucial for proper fermentation. The honey not only feeds the yeast but also adds subtle sweetness that balances the earthy barley flavor.

To the yeast mixture, gradually add the 4 cups barley flour while stirring with a wooden spoon. The barley flour is heavy and dense, so you’ll need to work it in thoroughly. Once incorporated, add the 2 teaspoons olive oil and 1.5 teaspoons sea salt. Mix until a shaggy dough forms—it should pull away from the sides of the bowl but still feel sticky.

Here’s the thing—barley dough is trickier than wheat-based dough because it absorbs moisture differently. If it feels too dry, add 1 tablespoon of ice water at a time until you reach a soft, slightly tacky consistency. You’re aiming for dough that holds together when pressed but still feels slightly sticky to the touch.

Turn the dough onto a lightly floured surface and knead vigorously for 8-10 minutes. Barley dough doesn’t develop gluten like wheat dough, so focus on distributing the ingredients evenly rather than creating smooth elasticity. You’ll know it’s ready when the dough feels uniform and springs back slowly when poked.

I like to use a bench scraper to help fold and turn the dough during kneading—this prevents overworking it while ensuring even development. If the dough sticks excessively, wet your hands slightly to prevent tearing. The goal is a cohesive mass that holds its shape when shaped into a ball.

Lightly oil a large bowl, place the dough inside, and cover it with a damp kitchen towel or plastic wrap. Let it rise in a warm place (like a turned-off oven with a bowl of hot water) for 1-2 hours, or until it has doubled in size. Barley dough rises more slowly than wheat dough, so be patient—rushing this step leads to dense, flat bread.

You’ll notice the dough puffs up noticeably and may develop small bubbles on the surface. Gently press your finger into the dough—if it springs back very slowly (not immediately), it’s ready. If your kitchen is cold, extend the rising time to 2.5 hours to ensure proper fermentation, which develops those complex nutty flavors.

Punch down the risen dough to release air, then shape it into a 9×5-inch loaf by flattening it slightly and folding the edges toward the center. Place the shaped loaf on a baking sheet dusted with ¼ cup cornmeal—this prevents sticking and adds a subtle crunch to the crust. Cover loosely with plastic wrap and let it rise for another 30-45 minutes until it puffs slightly again.

For a rustic look, you can also shape the dough into a free-form boule or batard. Brush the top with a little water if you want extra browning during baking. The second rise is quick—just enough to let the dough expand slightly before baking. If you’re short on time, you can skip this rise and bake immediately, though the texture will be denser.

Preheat your oven to 375°F for at least 20 minutes—this ensures even heat distribution. Bake the loaf for 35-40 minutes, rotating the pan halfway through for even browning. The bread is done when the crust is deep golden brown and the internal temperature reaches 190-200°F on an instant-read thermometer.

Here’s how to test doneness: Tap the bottom of the loaf—it should sound hollow when fully baked. If it’s still dense inside, return it to the oven for another 5-10 minutes. The aroma should be rich and nutty, with a hint of caramelized sweetness from the honey. Let the bread cool on a wire rack for at least 30 minutes before slicing—this prevents a gummy interior.

Essential equipment for this dish

Mixing Essentials

Start with a large mixing bowl (I use my 12-quart stainless steel Cambro) to handle the sticky barley dough. A wooden spoon works best for mixing—it’s gentle on the dough and helps distribute the dense barley flour evenly.

For measuring, a digital kitchen scale (like the OXO Good Grips) ensures precision, especially since barley flour is heavier than all-purpose flour. 🌾

Kneading Tools

Barley dough is less elastic than wheat dough, so you don’t need a stand mixer—your hands and a bench scraper (like the Jamie Geller) are perfect. If you prefer a mixer, use the dough hook attachment on low speed for 3-4 minutes to avoid overworking.

A lightly floured surface (I use King Arthur unbleached flour for dusting) prevents sticking while kneading.

Rising Containers

For the first rise, a large, lightly oiled bowl (I keep a 10-inch ceramic bowl dedicated to dough) works best. Cover it with a damp kitchen towel or plastic wrap to retain moisture—barley dough dries out faster than wheat dough.

A proofing basket (like the banneton) is ideal for shaping free-form loaves, but a parchment-lined loaf pan (I use USA Pan) is great for beginners.

Baking Gear

Preheat your oven with a baking stone (I swear by the West Bend) or inverted baking sheet for 20 minutes to mimic a professional oven’s heat. A spray bottle with water creates steam for a crispy crust—just mist the dough 1 minute before baking.

An instant-read thermometer (like the Thermoworks Smoke) ensures you don’t overbake; aim for 190-200°F internal temp.

Cooling and Storage

Let your loaf cool on a wire rack (I love the OXO Good Grips) to prevent sogginess. For storage, a bread box (like the West Elm) keeps it fresh for 5 days, or wrap slices in parchment paper for freezing.

A sharp serrated knife (I use the Mercer Culinary) gives clean slices without crushing the crumb.
