This 12-hour bread recipe transforms your kitchen into an artisanal bakery with minimal effort—no kneading, no stress, just a slow-fermented loaf that rivals store-bought. The secret lies in high hydration and overnight fermentation, which develop deep flavor and an irresistibly crisp crust. I perfected this method after years of experimenting with sourdough and French baguettes, and it consistently delivers restaurant-quality results at home.
The process begins with mixing a simple dough of bread flour, water, yeast, and salt, then letting it rest at room temperature for 12 hours. This slow fermentation builds complexity and improves digestibility, while shaping the dough into a classic boules or batards creates that signature crust. A hot oven and steam ensure a golden, crackling exterior with a soft, airy interior—no special equipment required beyond a Dutch oven or baking stone.
What you’ll end up with is a loaf so good it disappears faster than you can slice it—crisp on the outside, tender and open-crumb inside, with a nutty aroma that fills your home. Perfect for breakfast toast, sandwiches, or simply enjoying with butter and jam, this bread proves that great baking doesn’t require hours of your time. The key is patience, and the reward is a loaf that tastes like it came from a Parisian boulangerie.
Whether you’re a beginner or an experienced baker, this recipe delivers foolproof results. The 12-hour fermentation does most of the work while you sleep, so you can enjoy the process without sacrificing quality. Ready to bake bread that impresses? Let’s get started with the ingredients and step-by-step instructions that make this possible.
Ingredients for 12 hour bread
Four simple ingredients transform your kitchen into a Parisian bakery overnight—no kneading, just patience.
| Ingredient | Amount | Notes |
|---|---|---|
| Bread Flour 🌾 | 3 ½ cups | High-protein for structure |
| Warm Water 💧 | 2 ¼ cups | 105°F for optimal yeast activation |
| Active Dry Yeast 🍞 | ½ tsp | Or 1 packet instant yeast |
| Kosher Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Extra-Virgin Olive Oil 🫒 | 2 tbsp | For dough handling |
| Cornmeal 🌽 | ¼ cup | For dusting work surface |
| Ice Water ❄️ | ½ cup | For shaping dough |
| Coarse Sea Salt 🧂 | 1 tsp | For final crust scoring |
The bread flour is non-negotiable here—King Arthur or Caputo make all the difference for that open crumb structure. Bulk bins at Whole Foods often have excellent options if you want to splurge. Yeast quality matters too: Saf-Instant or Red Star are my go-tos, but check the expiration date—old yeast won’t wake up properly. The water temperature is critical: too hot kills the yeast, too cold and it won’t activate. 105°F is perfect—use a thermometer if you’re unsure. For the olive oil, California Gold or Bertolli add subtle fruity notes that elevate the finished loaf.
No bread flour? All-purpose plus 2 tbsp vital wheat gluten gets you close, though texture won’t be identical. Running short on yeast? Baking powder at half the amount can help, but flavor will suffer. The cornmeal is just for dusting—semolina works too if you’ve got it. For shaping, ice water on your hands prevents sticking better than flour. And that coarse sea salt? Maldon flakes are ideal, but any flaky salt will do. Pro tip: if your dough feels sticky but won’t handle, let it rest another 15 minutes—it’ll come together.
This dough keeps beautifully—2 days in the fridge if you want to slow ferment longer. For scoring, a lamé or sharp razor works best. Bake immediately after shaping for that perfect crust. Leftovers? Toast within 3 days for best texture. The crust freezes well too—wrap tightly in foil and reheat in a 350°F oven for 10 minutes.

Step-by-step instructions for overnight crusty loaf
Here’s how to make a rustic, no-knead loaf with minimal effort and maximum flavor.
Mix the Dough and Let It Rest Overnight
In a large bowl, combine the 3.5 cups bread flour with the 1.5 tsp kosher salt. Make a well in the center and add the 0.5 tsp active dry yeast and 2 tbsp extra-virgin olive oil. Slowly pour in the 2.25 cups warm water (around 105°F) while stirring with a wooden spoon until a shaggy dough forms.
Cover the bowl loosely with plastic wrap or a damp kitchen towel. Let it rest at room temperature for 12 hours, or until the dough has nearly doubled in size and looks bubbly around the edges. This slow fermentation develops deep flavor and a light, airy crumb. If your kitchen is cold, place the bowl in a slightly warm spot to encourage fermentation.
Shape and Score the Dough
After the overnight rest, the dough should be noticeably puffy but still soft. Turn it out onto a surface lightly dusted with the 0.25 cup cornmeal to prevent sticking. Gently fold the dough over itself 2-3 times to deflate it slightly, then shape it into a loose round or oval by pulling the edges toward the center.
Place the dough seam-side up on a parchment-lined baking sheet or directly onto a baking stone. Let it rest for 15-20 minutes at room temperature while you preheat your oven to 450°F. This final rest helps the dough relax and develop tension for a better oven spring. While waiting, sprinkle the 1 tsp coarse sea salt evenly over the surface for a crisp, flavorful crust.
Bake for a Crispy, Golden Crust
Once the oven reaches 450°F, place the dough inside and immediately pour 0.5 cup ice water into a small oven-safe dish on the lower rack. This creates steam, which helps the bread rise dramatically and develop a crisp crust. Bake for 25-30 minutes until the bread is deep golden brown and sounds hollow when tapped on the bottom.
For extra browning, you can also spray the oven walls with water after the first 10 minutes of baking. The bread is done when it reaches an internal temperature of 205-210°F and has a rich, caramelized crust. Remove from the oven and let it cool on a wire rack for at least 30 minutes before slicing—this ensures clean cuts and prevents a gummy crumb.
Serve Warm for Maximum Enjoyment
Slice the loaf with a sharp serrated knife and serve warm with butter, jam, or your favorite toppings. The interior should be soft and airy, with a crisp, crackly crust that gives way to a tender crumb. If you’re not serving it immediately, store the bread in a paper bag at room temperature for up to 3 days to keep it fresh.
This method delivers a rustic, artisanal-quality loaf with minimal effort—perfect for busy bakers who still want a homemade touch. The overnight fermentation does the heavy lifting, so you only need to shape and bake. Enjoy the process and the delicious results!
Pro Tips For Making 12 Hour Bread
- Measure Water by Weight: Bread flour absorbs water like a sponge, and eyeballing it leads to dough that’s either too stiff or too sticky. Use a kitchen scale for the water—100% hydration means 500g flour needs 500g water, no guesswork. I learned this after scrapping three batches where the dough either wouldn’t hold shape or spread everywhere.
- Bloom Yeast in Oil: Skip the warm water for blooming—mix the yeast with a teaspoon of olive oil first, then add the water. The oil coats the yeast, making it activate faster and more evenly, especially in long ferments. My dough now rises consistently, even when the kitchen’s chilly.
- Salt the Water Fully: Don’t hold back—dissolve the full amount of kosher salt in the water upfront. Salt dissolved early prevents uneven flavor and strengthens gluten development over the 12-hour rest. I used to sprinkle it later, and the bread always tasted blander.
- Stretch and Fold Twice: After the initial 2-hour bulk ferment, do two sets of stretch-and-folds—once at 4 hours and again at 8 hours. This builds tension without overworking the dough, giving you that open, airy crumb. I skipped this once and ended up with dense, gummy bread. Not worth it.
Creative variations of these flavors
Herb-Infused Twist
Transform your loaf into a fragrant herb bread by adding 2 tbsp finely chopped fresh rosemary or 1 tbsp dried thyme directly to the dough during mixing. For a Mediterranean touch, mix in 1 tsp dried oregano and 1 tsp garlic powder—these herbs develop beautifully during the 12-hour fermentation. I love using Penzeys Spices for their vibrant, flavorful blends. 🌿
Sweet Swirl Loaf
Create a sweet variation by folding in ½ cup honey or ⅓ cup maple syrup with the yeast and water. For a cinnamon-raisin twist, mix 1 tbsp ground cinnamon and ½ cup raisins into the dough before shaping. The slow fermentation enhances the sweetness, making it perfect for breakfast toast or French toast. 🍯
Seeded Whole Grain
Boost nutrition and texture by replacing 1 cup of bread flour with whole wheat flour or spelt flour. Add 2 tbsp toasted sesame seeds, 1 tbsp flaxseeds, or 1 tbsp sunflower seeds for crunch. These seeds add a nutty depth and make the loaf heartier. Store-bought seeds like Bob’s Red Mill work perfectly. 🌾
Savory Cheese Loaf
Add ½ cup shredded Gruyère or Parmesan cheese to the dough for a rich, cheesy flavor. The cheese melts slightly during baking, creating pockets of gooey goodness. For extra flavor, sprinkle ½ tsp smoked paprika or black pepper into the dough. This version pairs beautifully with soups or charcuterie boards. 🧀
Dutch Oven Sourdough Hybrid
For a sourdough-inspired loaf, replace ½ cup of water with ½ cup active sourdough starter (unfed). The tangy flavor develops during the 12-hour rest, giving you a rustic, artisanal taste without the complexity of a full sourdough process. Bake in a Dutch oven for an even crispier crust. 🥖
Gluten-Free Adaptation
For a gluten-free version, use a 1:1 gluten-free bread flour blend (like King Arthur or Bob’s Red Mill) and add 1 tbsp xanthan gum to improve texture. Reduce the water by ¼ cup since gluten-free flours absorb less. The fermentation time remains the same, but expect a denser crumb. This works best with 10-12 hours of rest. 🌱

Frequently asked questions
Why does this bread need a 12-hour fermentation?
The 12-hour fermentation is the secret to developing deep flavor and improving digestibility. This slow rise allows the yeast and natural enzymes to break down gluten and starches, creating a lighter, more open crumb and a complex, nutty taste. It also mimics traditional artisanal methods where dough rests overnight for better texture.
Can I use all-purpose flour instead of bread flour?
You can substitute all-purpose flour, but your bread may lack the professional open crumb structure. For best results, add 2 tablespoons vital wheat gluten per cup of all-purpose flour to improve elasticity. The texture won’t be identical, but it’ll still be delicious. For a true artisanal loaf, bread flour is worth the small extra cost.
What if my dough doesn’t rise overnight?
Cold temperatures or old yeast are the most common culprits. First, check your yeast packet’s expiration date—it should be fresh. If your kitchen is chilly (65°F or below), place the dough in a slightly warm spot (like near the oven with the light on) to encourage fermentation. If it still doesn’t rise, try adding 1 extra teaspoon of yeast and let it rest another 4-6 hours.
Do I really need to use a Dutch oven or baking stone?
While a Dutch oven or baking stone creates the best crust, you can still get great results with a regular baking sheet. For extra crispiness, place the dough on a sheet pan, pour ½ cup boiling water into a small oven-safe dish, and bake as directed. The steam from the water helps create that signature crust. Just expect slightly less dramatic browning.
How do I store leftover bread to keep it fresh?
Wrap the cooled loaf in a paper bag (not plastic) and store at room temperature for up to 3 days. For longer storage, freeze slices wrapped in foil—they’ll stay fresh for 2-3 months. To revive stale bread, sprinkle with water and toast in a 375°F oven for 5-10 minutes until crispy again.
