Why you’ll love this recipe
This recipe is a variation of my popular Milk & Honey Whole Wheat Bread recipe. This is a perfectly soft and slightly sweet sandwich bread.
Although this sourdough wheat bread recipe takes a good 12+ hours from start to finish, the vast majority of the time is hands off.
To make this recipe even more convenient, you can let the dough rise over night. A long rise in the refrigerator does only good things for the bread.

Ingredients

Ingredient Notes
- Sourdough Starter – This recipe was developed using 100% hydration starter. You will need to adjust the liquid or flour in the recipe if you’re starter isn’t at 100% hydration.
- Bread Flour has a high protein content. Higher protein means better gluten development.
- Whole Wheat Flour does not have quite as much of the gluten forming properties of bread flour. Using a combination of whole wheat and bread flour makes a loaf that has great whole grain flavor, yet rises tall in the oven. You can adjust the proportion of wheat vs. bread flour to make a loaf to your liking.
- Milk – Scalding denatures (breaks down) proteins in the milk which can interfere with gluten development.
- Honey – Adds wonderful flavor, enhances browning and makes the crumb soft and slightly sweet.
- Salt – For flavor.
- Sesame Seeds – For crunch and flavor on the crust.
How to make Whole Wheat Sourdough Sandwich Bread
See the recipe card for detailed measurements and instructions.

- Combine the starter, water and 1 cup of the bread flour to form a thick batter. Cover the bowl and set the mixture aside for 30-60 minutes.
- Add the rest of the ingredients.
- The dough will start out quite rough and sticky.
- Continue kneading until the dough begins to gather on the hook and pulls away from the sides of the bowl. Place the dough in an oiled bowl, turning once to coat the dough. Cover and set aside in a warm spot.

- After 30 minute, lift one side of the dough and fold it into the middle of the dough. Repeat with the other three sides of the dough then flip the dough over.
- Fold the dough every hour. After 3 hours the dough should be lively, elastic and airy.
- Cover the bowl tightly and refrigerate overnight. (If you prefer you can skip the refrigeration step and continue shaping the loaf right after the initial fermentation.)
- The next morning continue with shaping.

- Without kneading, use your hands to pat the dough into a rectangle.
- Roll the dough to a log.
- Set it into a lightly greased loaf pan

- Cover the pan and set it aside for 1 1/2 – 2 hours.
- The loaf will rise to fill up the loaf pan.

- Cut a slash down the center of the loaf. Brush with egg wash and sprinkle with sesame seeds (optional).
- Bake until the interior is 200F.

A timeline for making this recipe
- If your starter needs feeding, do that the night before or early in the morning of the day you want to make the dough.
- Mix the dough in the afternoon, allow it to ferment for 3-6 hours then refrigerate the dough before going to bed.
- Take the dough out of the refrigerator first thing in the morning, shape the loaf and set it into the pan.
- Leave the loaf to rise for 1 1/2- 2 hours, or as long as is needed to almost double in size.
- To make and bake the dough in the same day, feed your starter the evening before so it’s active by morning. Start the dough early in the morning and it should be ready to bake by late afternoon or early evening.
Storage
Sourdough Whole Wheat Bread stays fresh at room temperature for 2-3 days. The bread (sliced or whole) can be frozen for up to a month.

Whole Wheat Sourdough Sandwich Bread
Ingredients
- 8 ounces active sourdough starter (1 cup (100% hydration))
- 4 ounces warm water (½ cup)
- 10 ounces bread flour (2 cups, see note)
- 8 ounces whole milk (1 cup)
- 1 ½ ounces honey (2 tablespoons)
- 1 ½ teaspoons table salt
- 7 ½ ounces whole wheat flour (1 ½ cups)
- 1 egg for egg wash
- Sesame seeds for garnish (optional)
Instructions
- In the bowl of a stand mixer or in a large mixing bowl, combine 8 ounces active sourdough starter, 4 ounces warm water and 1 cup (5 oz) of the bread flour to form a thick batter. Cover the bowl and allow the mixture to rise for 30-60 minutes. Warm 8 ounces whole milk until scalding hot then set it aside to cool until it is slightly warmer than body temperature.
- Add the scalded milk, 1 ½ ounces honey and 1 ½ teaspoons table salt to the sponge. Stir to combine. Add 7 ½ ounces whole wheat flourand stir until the batter looks like thick pancake batter. If using a stand mixer, switch to the dough hook.
- With the mixer running, slowly add the remaining bread flour. Continue mixing until the dough begins to gather on the hook and pulls away from the sides of the bowl. Knead for 5 minutes. If mixing by hand, add as much of the flour as you can in the bowl then finish kneading in the rest of the flour by hand.
- Dump the dough onto a lightly floured surface. The dough should be soft and slightly sticky. Knead to form a smooth ball. If the dough is very sticky sprinkle a little more flour as you knead. Place the dough in an oiled bowl, turning once to coat the dough. Cover and set aside in a warm spot.
- After 30 minutes uncover the bowl, lift one side of the dough and fold it into the middle of the dough. Repeat with the other three sides of the dough then flip the dough over. You're basically turning the dough inside-out to redistribute the yeast and strengthen the gluten. Cover the bowl and after 60 minutes repeat the procedure again.
- Cover the bowl and after 60 minutes fold the dough one more time. By now the dough should be lively, elastic and airy. If the dough is still sluggish give it another hour or two at room temperature. If you want to finish making the bread in the morning cover tightly and refrigerate overnight. The next morning continue with shaping. Otherwise continue shaping the loaf on the same day.
- Turn the dough out onto a floured surface. Without kneading out the air, gently push the dough to a 9"x 12” rectangle. Tightly roll the dough from top to bottom to form a log shape. As you roll pinch the ends of the dough to form a tight roll.
- Grease a 9"x 5" loaf pan with a very light film of vegetable oil or with baking spray. Set the dough into the pan and cover with oiled plastic wrap. Set in a warm place to rise until the dough almost doubles in size, about 1 ½ hours. It will take longer to rise if the dough is cold from a night in the refrigerator. In the meantime, preheat the oven to 350 °F.
- Use a sharp knife or razor to cut a 1/2" deep slash down the center of the loaf. Brush the dough with egg wash and sprinkle with seeds.
- Bake about 35-40 minutes until golden brown and and a toothpick inserted in the center comes out clean. The interior temp should be about 200 °F.
- Cool in the pan about 5 minutes before turning out onto a cooling rack. Cool to room temperature before slicing.

Some things I’ve learned:
If you add no more than 10% whole wheat, the rise, crumb and density will be the same. Adding a bit of fat (5-6 grams) to a bread recipe makes it softer.
Cold proofing makes the yeasts that cause rise to sleep, while the bacteria that adds depth of flavor, stays active. That’s why a cold proof of 8-16 hours after shaping creates very little rise but makes a loaf more flavorful. Take it out of the fridge, slash it deeply and at a 45-degree angle, throw it into a screaming hot 500°F oven and covered baking vessel, for 10 minutes then lower to 450°F for 30-35 minutes, and watch it pop after the yeasts awaken from their cold nap. No peeking. It will work.
For the oven:
On a colder day, take a few hours and, using a quality digital thermometer with a cabled or “leave in” probe centered on the center rack, verify the temperature of the oven for the commonly used baking temperatures: 350, 375, 400, 425, 450 and 500. Make a notation of the actual setting to obtain the proper temperatures. Most ovens can be off by as much as 50°F. Some newer models have a calibration adjustment.
When calibrating, I place a heavy piece or two of cast iron bakeware on the bottom-most rack space or directly on the heat shield to act as a thermal load in order to steady the temperature. It slows the calibration process but improves the accuracy. Heating elements cycle on and off. There’s a rapid heating followed by a gradual cooling; then it repeats. The thermal load significantly flattens that out.
Made this today replacing 1/2 cup whole wheat flour with wheat bran. Found out my oven temp is off, will have to increase temps at least 10 degrees in the future. Looks & smells great
Could I replace some of the wheat flour with wheat bran? How much would be good?
You could. Maybe start with 1/2 cup? You could also check out my recipe for Multigrain Bread.
@Eileen Gray,
Thanks, I’ll try 1/2 cup & let you know how it goes. I also saved your multigrain sourdough recipe
This is our go-to, everyday bread that I’ve been making for years. I’ve made it with entirely whole wheat flour which of course produces a heavier but still delicious loaf. I’ve used buttermilk instead of regular, just to use up the buttermilk, and the result was fantastic. There is no going back to store bought bread for us.
A wonderful bread; been making it for 2-3 years, and I can’t believe I didn’t give a shout out until now-so sorry! I double the recipe, and get 3 loaves; and sprinkle it with rolled oats instead of the sesame seeds.
