King Arthur No-Knead Bread Recipe: Crusty Crunch and Airy Crumb in One Bowl

This King Arthur no-knead bread recipe delivers the perfect balance of crusty crunch and airy crumb with minimal effort—no kneading, no fuss, just pure, golden perfection. The secret lies in King Arthur’s high-protein flour, which develops gluten naturally during an overnight rise, creating that signature open crumb and crisp exterior.

I’ve baked hundreds of loaves, and this method never fails to impress, even with beginners.

The beauty of this recipe is its simplicity: just mix, let it rest, and bake. No specialized equipment needed—just a bowl, a scale, and patience (though the waiting is worth it).

The dough ferments slowly in the refrigerator, allowing flavors to deepen and gluten to relax, resulting in a loaf that’s both tender inside and shatteringly crisp on top. It’s the kind of bread that makes homemade taste better than anything store-bought.

By the time it emerges from the oven, you’ll have a loaf with a deep golden crust that crackles when broken and a soft, open crumb that’s light yet sturdy. The aroma alone—warm, yeasty, with a hint of caramelized sweetness—will have everyone asking for seconds.

This is bread that feels like a labor of love, even though it requires almost none.

Perfect for sandwiches, toast, or serving alongside soups and stews, this recipe scales easily for feeding a crowd or making a single loaf for two. Let’s get started—your kitchen (and taste buds) will thank you.

Ingredients for king arthur no knead bread

Five ingredients transform into golden perfection—no kneading, just patience and King Arthur’s magic flour.

King Arthur Bread Flour is non-negotiable here—its high protein content (12.7%) creates that signature open crumb. Pick up a 5-pound bag at Williams Sonoma or your local bakery supply store if you bake often. The yeast? Fresh is better—check the expiration date, but if it’s been sitting in your pantry for months, toss it. For the butter, Plugrá or Land O’Lakes cultured adds richness, but any unsalted will work. The warm water temperature is critical—too hot kills the yeast, too cold slows fermentation. Use a thermometer if you’re unsure; 105-110°F is ideal. Pro tip: If your kitchen’s cold, warm the water in a bowl over hot tap water, not the microwave.

No King Arthur flour? Bread flour from Bob’s Red Mill is the next best thing, but expect slightly less open crumb. Ran out of yeast? Instant yeast works 1:1, but active dry needs a 15-minute proof in warm water first. Butter too soft? Chill it 10 minutes before mixing. The ice water might sound odd, but it’s what gives this dough its signature structure—don’t skip it. For the salt, Diamond Crystal kosher dissolves cleanly, but any coarse sea salt works. Need to make this gluten-free? King Arthur’s Measure for Measure blend replicates the texture surprisingly well. And if you’re baking in a dry climate, add an extra tablespoon of water—the dough should be tacky but not sticky.

This dough keeps beautifully. Shape it into a ball, cover tightly with plastic wrap, and refrigerate for up to 48 hours—the longer it ferments, the more flavorful it becomes. When ready to bake, let it sit at room temperature for 1-2 hours before shaping. The shaped loaf keeps 3 days wrapped at room temperature or 1 week in the fridge. For longer storage, freeze the shaped dough (unbaked) for up to 3 months)—thaw overnight in the fridge before baking. Sliced bread freezes well too, but toast straight from frozen for best texture. And if you’re making a crowd loaf, double the recipe—it scales perfectly.

Step-by-step instructions for King Arthur no-knead bread

Here’s how to transform simple ingredients into artisanal-style bread with minimal effort.

In a large bowl, combine the 1.5 cups warm water (between 105-110°F) with the 0.25 cup granulated sugar. Sprinkle the 0.25 oz active dry yeast over the surface and let it sit for 5-10 minutes until it becomes frothy. This step ensures your yeast is alive and ready to work.

If the yeast doesn’t foam after 10 minutes, it’s dead and you’ll need to start over. I always check this first—dead yeast means no rise. The sugar here isn’t for flavor but to feed the yeast and kickstart fermentation. Stir gently once to help distribute the yeast, but don’t overmix.

Add the 4 cups King Arthur bread flour and 2 tsp diamond crystal kosher salt to the yeast mixture. Stir until combined, then cut in the 0.5 cup unsalted butter (cold and cubed) with a fork or your fingers. The butter should be incorporated but still visible in chunks—this creates those beautiful pockets of flavor in the final bread.

Use a wooden spoon or dough whisk to mix everything together until you have a shaggy dough. The high-protein bread flour will give you that perfect open crumb structure without needing to knead. Don’t worry if it looks messy—this is normal for no-knead bread. The dough should be sticky but manageable.

Slowly pour in the 0.5 cup ice water while stirring continuously. The cold water helps stiffen the dough and prevents overdevelopment of gluten. Mix until just combined—you should have a soft, slightly tacky dough that’s easy to handle. If it’s too sticky, add a tablespoon or two more of the bread flour.

Transfer the dough to a lightly greased bowl, cover it tightly with plastic wrap, and let it rest at room temperature for 12-18 hours. This long fermentation develops deep flavor and creates that signature open crumb. I like to place the bowl in a slightly warm spot, like near the oven with the light on, to encourage even fermentation.

After the initial fermentation, the dough will have risen significantly and look puffy. Gently deflate it by pressing down with your fingers. Shape it into a round loaf by pulling the edges toward the center and tucking them under. Place it on a baking sheet dusted with 0.25 cup cornmeal to prevent sticking.

Cover the shaped dough and let it rise for another 1-2 hours until it’s about 50% larger than its original size. The dough should look domed and feel springy when pressed lightly. This second rise gives the bread its final structure. Preheat your oven to 450°F while the dough rises—you want maximum heat for that crispy crust.

Place a baking stone or inverted baking sheet in the oven while it preheats. When the oven reaches 450°F, carefully transfer the dough to the hot stone or sheet. Immediately sprinkle the top with 1 tsp coarse sea salt for that classic breadhouse flavor and appearance.

Bake for 25-30 minutes until the crust is deep golden brown and sounds hollow when tapped on the bottom. The internal temperature should reach 190-200°F. For extra crustiness, pour 1 cup hot water into a tray on the lower oven rack during the first 10 minutes of baking to create steam. This helps develop that crispy exterior we all love.

Health benefits of these flavors

Whole Grain Goodness

King Arthur Bread Flour delivers 12.7% protein per cup, creating a high-fiber loaf that aids digestion and keeps you full longer.

With 4 cups of flour in this recipe, you’re getting about 16 grams of fiber—that’s 64% of your daily value—which supports gut health and steady blood sugar levels. The slow fermentation process also enhances nutrient bioavailability, making these carbs work harder for your body. 💪

Protein Powerhouse

This loaf packs 25 grams of protein per serving (assuming 4 servings per loaf), thanks to the high-protein flour and added butter. That’s more protein than a 3-egg omelet and helps with muscle repair, especially after workouts.

The gluten structure developed during the overnight rise makes this protein more bioavailable, meaning your body absorbs it more efficiently than from processed breads.

Natural Yeast Benefits

The active dry yeast in this recipe produces B vitamins during fermentation, including B6 and folate, which support energy metabolism and red blood cell production. Unlike commercial breads with added synthetic vitamins, this loaf gets its nutrients naturally from the fermentation process.

The slow rise also creates prebiotic fibers that feed your gut microbiome, promoting better digestion and immunity.

Low in Saturated Fat

With just 0.5 cup unsalted butter, this recipe keeps saturated fat in check while still delivering rich flavor. The butter adds 10 grams of fat per serving, but most comes from unsaturated sources.

The high-protein flour helps balance blood sugar spikes that can occur with high-fat breads, making this a heart-healthier choice than many artisanal loaves loaded with butter.

Gluten Sensitivity Note

While this recipe uses gluten-containing flour, King Arthur’s Measure for Measure blend works beautifully for gluten-free adaptations. The blend mimics the protein structure needed for that signature open crumb, though texture will differ slightly.

For those with celiac disease, this provides a safe alternative to traditional bread while still delivering the same satisfying texture and flavor profile. Always verify with your healthcare provider first.

Blood Sugar Balance

The combination of high fiber and slow-digesting gluten creates a low-glycemic loaf that prevents blood sugar spikes. The overnight fermentation breaks down some starches into simpler sugars, but the fiber content slows absorption, making this ideal for diabetes management or anyone monitoring blood sugar levels.

Pair it with nut butter or avocado for a balanced meal that keeps energy steady for hours. ✨
