Side Dishes
This 7-day sourdough bread recipe transforms simple flour and water into a loaf with an open crumb, crisp crust, and tangy depth—no commercial yeast required.
The secret lies in patience: letting wild yeast and lactic acid bacteria develop over seven days creates a flavor and texture you won’t find in store-bought bread. I’ve perfected this method after years of baking, troubleshooting, and finally nailing the balance between hydration and structure.
The process begins with your starter—a living ecosystem of microbes that needs consistent feeding for seven days to reach peak activity. Each day builds on the last, with bulk fermentation times that develop gluten strands for that signature chewy yet airy crumb.
The payoff comes when you shape the dough, proof it just right, and bake it with steam to create that coveted crisp crust and open crumb structure.
By the final day, you’ll have a loaf with a rustic chew, golden crust, and a tangy aroma that fills your kitchen. This bread pairs perfectly with soups, stews, or simply buttered and sliced for breakfast.
The method is precise but rewarding—ideal for bakers who appreciate the craft of slow fermentation.
Whether you’re a beginner eager to master sourdough or a seasoned baker refining your technique, this seven-day journey delivers a loaf that’s worth every moment of waiting. Let’s get started on day one.
Ingredients for 7 day bread
Flour, water, salt, and patience—these are your building blocks for sourdough magic.
| Ingredient | Amount | Notes |
|---|---|---|
| Unbleached All-Purpose Flour 🌾 | 16 cups | King Arthur or Bob's Red Mill preferred |
| Active Sourdough Starter 🍞 | ½ cup | 100% hydration, bubbly and active |
| Filtered Water 💧 | 10 cups | Room temperature, 70-75°F |
| Kosher Salt 🧂 | 1 ½ tbsp | Diamond Crystal preferred |
| Whole Wheat Flour 🌾 | 2 cups | For structure and flavor |
| Honey 🍯 | 2 tbsp | For starter feeding (optional) |
| Rice Flour 🌾 | ¼ cup | For dusting work surface |
| Cornmeal 🌽 | ¼ cup | For baking sheet |
| Unsalted Butter 🧈 | ½ cup | For serving (optional) |
The flour is where it all starts. King Arthur or Bob's Red Mill unbleached all-purpose gives you the best balance of protein and gluten development for this seven-day process. Whole wheat adds depth but can make the dough stickier, so add it gradually if you're new to sourdough. Your starter should be bubbly, active, and doubling in size within 4-6 hours—that means it's ready to bake with. For the water, room temperature is key (70-75°F). Too cold and fermentation slows; too warm and it gets out of control. If you're in doubt, use a thermometer. The salt? Diamond Crystal kosher dissolves better than table salt and enhances flavor without overpowering.
No honey for feeding your starter? White sugar works just as well—just use the same amount. Running out of whole wheat? Substitute rye flour at half the quantity for extra tang. The rice flour and cornmeal might seem minor, but they're essential—rice flour prevents sticking when shaping, and cornmeal gives that perfect crust color. For the butter, any unsalted kind works, but European-style butter has more fat content for richer flavor. Pro tip: if your starter isn't active enough, try feeding it twice daily for 24 hours before starting the recipe. Patience is everything here.
Store your starter in the fridge between feedings—it'll last weeks this way. The dough for baking keeps best in the fridge overnight, covered, for up to 24 hours before shaping. Once baked, this bread stays fresh 3-4 days at room temperature, wrapped in a cotton towel. For longer storage, slice and freeze portions—up to 3 months. The crust gets crispier as it cools, so resist the urge to cut into it right away. Trust me, the wait is worth it.

Step-by-step instructions for 7-Day sourdough bread
Let's bake a loaf with depth of flavor and perfect texture through careful fermentation.
Feed and Prepare the Sourdough Starter
First, feed the 0.5 cup active sourdough starter by mixing it with 2 tablespoons honey and 2 cups filtered water (room temperature). Stir well and let it sit at room temperature for 4-6 hours until it's bubbly and has doubled in size. This feeding ensures your starter is strong and active for the long fermentation ahead.
Check for readiness by performing the float test—drop a small spoonful into a glass of water. If it floats, it's ready. If not, feed it again and wait another 2 hours. A properly fed starter is the foundation of our flavorful loaf, so don't rush this step.
Mix the Dough and Begin Bulk Fermentation
In a large bowl, combine the 16 cups unbleached all-purpose flour, 2 cups whole wheat flour, and 1.5 tablespoons kosher salt. Make a well in the center and add the fed starter along with 8 cups filtered water. Mix with a wooden spoon until a shaggy dough forms, then knead by hand for 10 minutes until smooth and elastic.
Transfer the dough to a lightly oiled bowl, cover with a damp towel, and let it rise at room temperature for 6-8 hours until it's puffy and has doubled in size. I like to do this overnight in the fridge for slower fermentation and better flavor development. Punch it down once during this time to redistribute the yeast.
Shape and Cold Proof the Dough
Turn the dough out onto a surface dusted with 0.25 cup rice flour and gently shape it into a round boule. Fold the edges under and tuck them tightly to create surface tension. Place the shaped dough seam-side up in a banneton or bowl lined with a floured towel.
Cover and refrigerate for 12-16 hours (overnight works perfectly). This cold proofing enhances flavor and makes scoring easier later. The dough should rise slowly and develop a tight, smooth surface. If it rises too much, it will collapse when baked—this is normal and expected.
Preheat and Bake the Bread
Preheat your oven to 450°F with a Dutch oven inside for 45 minutes. This creates the perfect steam environment for a crispy crust. While the oven heats, turn the dough out onto a piece of parchment paper dusted with 0.25 cup cornmeal. Score the top with a sharp razor in a crosshatch pattern.
Carefully transfer the dough (with parchment) into the hot Dutch oven. Bake covered for 30 minutes, then remove the lid and bake uncovered for another 15-20 minutes until the crust is deep golden brown and the internal temperature reaches 205-210°F. The bread should sound hollow when tapped on the bottom.
Cool and Serve with Butter
Remove the bread from the Dutch oven and let it cool on a wire rack for at least 1 hour before slicing. This resting period allows the crumb to set and prevents a gummy texture. The bread will continue to develop flavor as it cools.
Serve warm slices with 0.5 cup unsalted butter melted on top for that classic sourdough experience. The long fermentation gives this bread an open crumb, tangy flavor, and satisfying chew that improves with each day it sits on your counter.
Pro Tips For Making 7 Day Bread
- Weigh Your Whole Wheat: I learned this the hard way—measuring whole wheat flour by volume gives you a dry, dense loaf. Use a kitchen scale for the whole wheat portion (usually 10-20% of the total flour) to guarantee consistent hydration and a lighter crumb.
- Autolyse Before Mixing: Give your dough a 20-30 minute head start by mixing just the flour and water (no starter or salt) first. This relaxes the gluten and makes the final mix smoother—no more overworking the dough when you add the starter.
- Skip the Overproofing: Your dough’s ready when it’s just past the "float test" (drop a spoonful in water—if it floats, it’s good). Leaving it too long turns your bread into a dense brick. I used to wait "just a little longer," but the texture suffers.
- Use Filtered Water Only: Chlorine and minerals in tap water can kill your starter and weaken the gluten structure. Stick to filtered water for both the starter feed and dough mixing—your sourdough’s rise and flavor will thank you.
Make-ahead tips for this 7 day bread
Starter Prep Ahead
Start your sourdough starter 3-4 days before baking to ensure it's strong and active. Keep it on your counter and feed it daily with equal parts flour and water (e.g., 2 tbsp flour + 2 tbsp water) until it doubles in 4-6 hours.
Store it in a glass jar with a loose lid to allow airflow—this prevents mold while encouraging microbial growth. 💫
Dough Prep Timeline
Mix your dough 24 hours before baking and refrigerate it overnight for slower fermentation. This cold rise develops deeper flavor and easier handling. Divide the dough into portions if making multiple loaves, storing them in separate airtight containers lined with damp towels. Label each with the date to track freshness.
Freezing Dough Balls
Shape dough into boules or batards and freeze them on a floured tray for 1 hour before transferring to a ziplock bag for up to 3 months.
Thaw overnight in the fridge, then proceed with cold proofing. This shortcut saves time while preserving texture. Just add 1 extra hour to your proofing time after thawing.
Baked Bread Storage
Cool baked loaves completely before storing. Wrap in a cotton towel (not plastic) to maintain moisture and place in a paper bag at room temperature for 3-4 days.
For longer storage, slice and freeze portions in airtight containers for up to 3 months. Reheat slices in a 350°F oven for 5-7 minutes to restore crispness.
Starter Revival
If your starter sits unused for more than 1 week, revive it by feeding it daily for 3-4 days before using in recipes. Mix 50g starter + 50g flour + 50g water, cover, and wait for bubbles.
This ensures it's ready for your 7-day bread without starting from scratch. 🌱
Batch Prep Tips
Double the recipe and freeze half the dough for future baking days. Use silicon loaf pans for easy removal and uniform shape. Prep all ingredients (flour, water, salt) in measured containers the night before to streamline morning baking. This makes the 7-day process feel more manageable when you're busy.

Frequently asked questions
Why does this bread need 7 days to make?
The seven-day process allows wild yeast and beneficial bacteria in your starter to develop fully, creating complex flavors and a superior texture. Each day of fermentation breaks down gluten and starches, resulting in a lighter crumb and deeper tang. This slow method mimics traditional artisan bread-making where patience equals better flavor.
Can I substitute whole wheat flour with something else?
Yes! For a lighter texture, replace the 2 cups whole wheat flour with 2 cups rye flour or 1 cup each of whole wheat and spelt flour. If you want a lighter loaf, use 100% unbleached all-purpose flour instead. Just note that whole wheat adds fiber and flavor—removing it will make the bread less dense but slightly less tangy.
What if my starter isn't bubbly after feeding?
If your starter isn't active, try these fixes: feed it twice daily for 24 hours before baking, use warmer water (80-85°F) for feeding, or check for mold (discard if present). A weak starter often means it needs more time to develop. For emergencies, use 1 tsp commercial yeast mixed into the dough, but the flavor won't be as authentic.
How do I know when the bread is fully baked?
Your bread is done when the internal temperature reaches 205-210°F (use an instant-read thermometer) and the crust sounds hollow when tapped. The edges should pull away from the Dutch oven slightly, and the crust should be deep golden brown. If unsure, bake 5 more minutes—underbaking is worse than overbaking for sourdough!
Can I make this bread without a Dutch oven?
If you don't have a Dutch oven, bake the bread on a preheated baking sheet at 425°F for 5-10 minutes before transferring to the oven. For steam, place a metal tray with boiling water on the lower rack. The crust won't be as crispy, but the crumb will still be excellent. A cast-iron skillet also works well for similar results.
