Ingredients for america's test kitchen no knead bread
Four key ingredients transform into artisanal loaves with just 12 hours of patience.
| Ingredient | Amount | Notes |
|---|---|---|
| Bread Flour 🌾 | 4 cups | High-protein for optimal gluten structure |
| Instant-Release Yeast 🍞 | ¼ tsp | Active dry yeast works too |
| Diamond Crystal Kosher Salt 🧂 | 1 ½ tsp | Adjust to taste after kneading |
| Cold Water 💧 | 2 ½ cups | Chilled from refrigerator |
| Cornmeal 🌽 | ¼ cup | For dusting baking surface |
| Ice Cubes ❄️ | ½ cup | For steam generation |
| Extra-Virgin Olive Oil 🫒 | 1 tbsp | For greasing bowl |
| Unbleached All-Purpose Flour 🌾 | 2 tbsp | For dusting dough |
| Large Egg 🥚 | 1 whole | Optional for egg wash |
The bread flour is non-negotiable here—its high protein content (12-13%) develops the gluten network needed for that signature open crumb structure. King Arthur or Caputo are my go-to brands for consistency, but any high-protein bread flour will work. The yeast should be fresh—test it by proofing in warm water before using. Diamond Crystal kosher salt both work, but Diamond Crystal's coarser grains dissolve more evenly. For the water, cold is critical—it hydrates the flour gradually during the overnight fermentation, creating a more controlled rise. Some bakers swear by filtered water, but tap water works fine unless your local supply has an unusual taste or high mineral content.
No instant-release yeast? Active dry yeast requires 5 minutes of proofing in warm water before mixing. Short on bread flour? Substitute all-purpose at a 1:1 ratio, but expect a slightly denser crumb. The cornmeal can be swapped for rice flour if you're avoiding gluten, though the texture will differ. For steam generation, ice cubes are ideal—they melt slowly and create consistent steam, but you can use a metal bowl of hot water on the oven rack as a backup. The olive oil should be extra-virgin for greasing; regular vegetable oil lacks the fruity notes that won't affect flavor but do contribute to the professional finish. The egg wash is optional but recommended for that glossy crust—just don't overbeat the egg or you'll end up with a tough exterior.
This dough is remarkably forgiving—it can sit in the fridge for up to 48 hours before shaping if your schedule demands it. Shape the dough as soon as possible after the final rise for best results, but it can tolerate a 1-hour delay without significant texture loss. For storage, wrap cooled loaves in a clean kitchen towel inside a paper bag to maintain moisture. They'll stay fresh for 5-7 days at room temperature, or freeze for up to 3 months. To reheat, wrap the loaf in foil and warm at 350°F for 10 minutes—this restores the crust's crispness without overcooking the interior. The dough can also be divided and frozen before baking for convenient future loaves.

Step-by-step instructions for america's test kitchen no-knead bread
This method delivers a bakery-style loaf with minimal effort—just mix, wait, and bake.
Mix the Dough and Let It Rest
In a large bowl, combine the 4 cups bread flour, 0.25 tsp instant-release yeast, and 1.5 tsp diamond crystal kosher salt. I use a wooden spoon for this initial mixing to avoid activating the yeast prematurely. Gradually add the 2.5 cups cold water while stirring until a shaggy dough forms—it should be sticky but not runny. Cover the bowl with plastic wrap and let it rest at room temperature for 12 to 18 hours. This long fermentation develops deep flavor and proper gluten structure without any kneading.
The dough will look underdeveloped at first, but don't panic. The yeast needs time to hydrate fully and create the right texture. If your kitchen is warm, place the bowl in a cooler spot to prevent overproofing. You'll know it's ready when the dough has nearly doubled in size and feels slightly springy when pressed gently with a finger.
Shape and Prepare for Baking
Lightly grease a 9x5-inch loaf pan with 1 tbsp extra-virgin olive oil. Dust the inside generously with 2 tbsp unbleached all-purpose flour, tapping out any excess. Transfer the rested dough to the prepared pan, using a wet spatula if needed to help it release from the bowl. Gently shape it into a rough rectangle—no need for precision here. Cover the pan with plastic wrap and let it rest for another 1 to 2 hours at room temperature. This second rise ensures the dough is ready for baking.
During this final rise, the dough should expand noticeably within the pan. Press your finger into the dough—it should leave a slow, partial indentation. If the dough springs back quickly, let it rest a bit longer. The goal is to achieve a balance between structure and tenderness that results in an open crumb and crisp crust.
Preheat and Add Steam for Crust Development
Preheat your oven to 375°F. While it heats, place 0.25 cup cornmeal in a small bowl and add 0.5 cup ice cubes. This creates a steam reservoir that will help develop the crust. Once the oven reaches temperature, carefully transfer the dough pan onto the middle rack. Immediately place the cornmeal-ice mixture on the lower rack—this generates steam during the initial baking phase, which is crucial for that coveted crisp crust.
Bake the bread for 30 to 35 minutes, until the top is deep golden brown and the internal temperature reaches 205°F. The bread should sound hollow when tapped on the bottom. If the top browns too quickly, tent loosely with foil after 20 minutes to prevent overbrowning while allowing the interior to cook through.
Cool and Serve for Optimal Texture
Remove the bread from the oven and let it cool in the pan for 10 minutes. Then transfer it to a wire rack to cool completely. This cooling period is essential—it allows the gluten to relax and the crumb to set properly. If you cut into it too soon, the structure will be gummy rather than open and airy. For extra shine, brush the cooled loaf with a beaten egg wash made from the 1 whole large egg, but this is optional.
The finished loaf should have a thick, crackly crust and an even, soft crumb with large, irregular holes. Slice it with a serrated knife for clean cuts that reveal the perfect interior texture. Store any leftovers wrapped in a bread bag at room temperature for up to 3 days, or freeze for longer storage. The flavor actually improves over time as the crust dries out slightly.
Pro Tips For Making America'S Test Kitchen No Knead Bread
- WEIGH YOUR FLOUR: The ATK recipe calls for 500g bread flour—don’t eyeball it. A kitchen scale is worth its weight in gold here. I used to scoop and level, and my bread always came out denser than the test kitchen’s version. That extra 20g of flour makes a real difference in texture.
- STOP THE SPRINKLE: When scoring the dough before baking, resist the urge to sprinkle extra salt or cornmeal into the cuts. The recipe already accounts for this, and you’ll end up with uneven flavor or a gummy crust. Just use a sharp razor or lame—no extra seasoning needed.
- LET IT RISE LOW: Place your dough bowl in a warm spot (75°F is ideal), but don’t stack it on top of the fridge. I learned this after my first batch rose unevenly—one side puffed while the other stayed flat. A turned-off oven with the light on works perfectly if you don’t have a proofing box.
- SKIP THE SPRAY: The ATK recipe recommends a baking sheet with cornmeal, not flour. Flour burns easily and can make the crust taste bitter. Cornmeal gives the perfect grip for pulling the dough out without sticking—plus, it adds a subtle crunch that flour won’t. Trust the method.
Serving suggestions for this dish
Toast Perfection
This no-knead bread excels as toast, especially when sliced thick and toasted in a cast-iron skillet until the crust is crisp and golden. I like to brush the slices with 2 tsp melted butter and a pinch of flaky sea salt before toasting.
For extra richness, add 1 tbsp crumbled goat cheese on top and broil for 1-2 minutes until bubbly. 🥖
Classic Sandwich Bread
The open crumb structure makes it ideal for sandwiches where texture matters. Try it with sharp cheddar, turkey breast, and honey mustard—the crisp crust holds up to mayo-based spreads without getting soggy.
For a gourmet twist, use prosciutto di Parma and fresh mozzarella with a drizzle of balsamic glaze. The bread's neutral flavor lets the fillings shine.
Soup Companion
Serve warm slices alongside hearty soups like French onion or tomato basil. The crusty exterior soaks up broth beautifully while maintaining its structure. I often toast a few slices in the oven at 350°F for 5 minutes before serving to enhance their crispness.
For an elegant touch, arrange slices in a wooden bread basket—the golden crust contrasts perfectly with creamy soups.
Breakfast Pairings
Use it for breakfast by toasting thick slices and topping with scrambled eggs, crispy bacon, and avocado slices. The bread's sturdy structure handles runny yolks without falling apart.
For a sweet option, spread with almond butter and drizzle with honey and cinnamon. The crust's crunch adds a delightful contrast to creamy spreads. ✨
Garnish and Presentation
Enhance presentation by dusting the cooled loaf with 1 tsp semolina flour or crushed cornflakes for extra texture. For a rustic look, slice the loaf diagonally and arrange on a slate board with fresh rosemary sprigs.
The bread's natural golden hue pairs beautifully with dark greens like arugula or microgreens in a charcuterie setting.
Leftovers Reinvented
Transform stale slices into bread pudding or french toast. For bread pudding, cube the bread and soak in a mixture of 2 eggs, 1 cup milk, 1 tsp vanilla extract, and 2 tbsp sugar before baking.
For french toast, dip slices in a batter of 2 eggs, ¼ cup milk, and 1 tsp cinnamon, then cook in a buttered pan until golden. 💫

Frequently asked questions
Why does this no-knead bread need such a long fermentation time?
The extended 12-18 hour rest develops deeper flavor and improves digestibility through slow fermentation. This time allows the yeast and enzymes to break down complex proteins and sugars, creating a more complex taste and better gluten structure without overworking the dough. The result is a bread with a crisp crust and open crumb that's more flavorful than traditional quick breads.
Can I use all-purpose flour instead of bread flour?
Yes, but expect a slightly denser crumb. All-purpose flour has less protein (10-11% vs. bread flour's 12-13%), so the gluten network won't develop as fully. For best results, use a 1:1 substitution and let the dough ferment slightly longer (18-24 hours) to compensate. The crust will still be crisp, but the interior may be tighter.
What if my dough doesn't rise after overnight?
Check these three things first:
- Yeast freshness (proof a pinch in warm water—it should bubble in 5-10 minutes),
- Temperature (ideal room temp is 70-75°F), and
- Water temperature (should be cold, not warm). If it's still flat, try adding 0.25 tsp more yeast and letting it rest another 6-12 hours. If it still fails, your flour may be old or your environment too cold.
How do I get a crispier crust without a steam pan?
Place a metal bowl filled with hot water on the oven's lower rack when baking. For extra crispness, brush the dough with 1 tbsp melted butter before baking. Another trick: Bake on the middle rack (not top) for even heat circulation. If your oven runs hot, reduce temp to 350°F and bake 5-10 minutes longer for deeper browning.
Can I make this dough ahead of time and refrigerate it?
The dough can rest in the fridge for up to 48 hours before shaping. Just let it sit at room temp for 1-2 hours before the final rise. For longer storage, shape the dough, wrap tightly in plastic, and freeze for up to 3 months. Thaw overnight in the fridge before baking. This actually enhances flavor through extended fermentation.
