Tips for Making Multigrain Sourdough Bread
- Use a kitchen scale for accuracy when measuring ingredients to ensure consistency.
- Refrigerate the dough overnight for the best flavor development and easier handling the next morning.
- Pay attention to the rise time: Be patient and let the dough double in size before baking for a good rise.
- Shape the dough on a lightly floured surface: This prevents sticking and helps create a smooth, even loaf.
- Cover the dough with a damp towel during proofing to avoid drying out the top.
- Use a bench scraper when shaping the dough for easier handling.
- Bake in a hot Dutch oven or cast iron pan for the best crust. But we use an open bake using loaf pans with great success.

How To Make Multigrain Sourdough Sandwich Bread (freshly milled)
Step 1: Mix the Wet Ingredients
In a large mixing bowl, combine the sourdough starter, sunflower oil, water(warm), milk(warm milk), maple syrup, and egg(room temp). Slowly mix until well incorporated.
Step 2: Add Dry Ingredients
Using a Danish whisk, gradually add the dry ingredients to the wet mixture, creating a shaggy bread dough. Start with liquids and end with the flour.

Step 3: Rest the Dough
Cover the mixing bowl and let the dough rest for 30 minutes.
Step 4: Perform Stretch and Folds
After the initial rest, perform 4 sets of stretch and folds every 30-45 minutes. Make sure to cover the bowl in between each set. The dough will be stiff due to the whole wheat flour.
Step 5: Bulk Fermentation
Once you complete the stretch and folds, cover the dough and let it bulk ferment on the counter for 4-6 hours.
Step 6: Optional Overnight Rest
After the bulk fermentation, you can either proceed to the next step or refrigerate the dough overnight.
Step 7: Prepare for Shaping
If you refrigerated the dough, allow it to come to room temperature. Then, take the dough out of the lightly oiled bowl and divide it into two equal halves.
Step 8: Shape the Dough
Shape each half into rectangle logs and place them into your greased loaf pans.
Step 9: Second Rise
Cover each loaf pan with plastic wrap and let the dough rise until it reaches 1-2 inches above the pan’s edge.
Step 10: Preheat the Oven
Preheat your oven to 350°F.
Step 11: Bake the Bread
Bake the loaves for 25-45 minutes, or until the bread is lightly golden brown.
Step 12: Cool and Slice
Once baked, let the bread cool on a cooling rack for 1 hour. After cooling, slice into sandwich-sized pieces and enjoy!
