I use freshly milled wheat which adds a tremendous amount of flavor and nutrition.

It seems like for years I searched online for a completely whole wheat sourdough bread recipe and the few that I found just didn’t yield me the results I was looking for, so, I started recipe testing!

I looked at my easy sourdough sandwich bread recipe and started tweaking to accommodate for the freshly ground flour. A few changes later and a few so-so loaves led to this final recipe that is perfect!

This recipe can also be used for hot dog and hamburger buns, as well as, dinner roll! It’s a base recipe for most of your bread products.

If you do not mill your own wheat you can use store bought whole wheat flour, however, it will be hard red wheat which will give you a bit of a denser loaf. I used mostly hard white wheat with just a bit of hard red wheat in this recipe. King Arthur has a whole wheat flour that is “white” whole wheat, meaning it uses hard white wheat. If you can find this one, your loaf will turn out very similar to mine.

Just a back story on why this recipe was so important for me to figure out. I am in the process of transitioning my baking to all freshly ground wheat. I have found that bread products made with freshly milled wheat are more filling and obviously they are much more nutritious. I feel like I can eat a loaf of bread if it’s made with white flour, but, with whole wheat, I get full on just a slice or 2! Win, Win!

So, let’s jump in to this recipe!

The night before, add 1 cup of water and 1/2 cup of active, fed sourdough starter. Mix together until it resembles a milky liquid.

Next add 3 tablespoons of olive oil and 2 tablespoons of honey. Mix until combined.

Add in 1 1/2 teaspoon of fine sea salt.

Now it’s time to start adding in the flour. If you are using store bought flour, fluff up the flour before scooping it out. Freshly ground wheat is much fluffier because it hasn’t settled, so, the measurements will be more similar if you whisk up the flour before measuring out.

I add in 3 1/2 cups of flour and mix just until combined. I move it to the stand mixer and start kneading it. I ended up adding in 2-3 tablespoons of additional flour. If hand kneading, reserve the 2-3 tablespoons of flour for kneading. Don’t add too much flour, as it will cause a very dense loaf.

Knead for 8-10 minutes until the dough is smooth and stretchy.

Move the dough to a greased bowl large enough to hold the rising dough overnight. Cover with something airtight. I use bowl covers from Amazon. You can use plastic wrap or bees wax wrap.

Leave on counter for the night.

The next morning, remove the dough from the bowl. If you have to, you can add a small amount of flour to help with shaping the dough. I found I didn’t have to. But, if you do, just use enough to work the dough.

Instead of punching down the dough, simply remove the dough and place on your work station. Then pat it out to a rectangle. This will slightly degas the dough but won’t knock all the air out from the overnight fermentation. Being whole wheat, you want to retain as much air as possible to yield a fluffier loaf.

After shaping into a loaf, add to a greased loaf pan. Cover and let rise until it tops over the pan. Mine took 2 1/2 hours.

Preheat the oven to 375 degrees F.

Brush with a beaten egg and you can top with everything seasoning. It really adds so much flavor to the bread but this is optional.

Bake for 40-45 minutes until golden brown.

Place on cooling rack to cool completely before slicing.

This bread tastes so nutty and a bit sweet from the honey. It’s soft, and, although it doesn’t rise quite as high as a loaf made with white flour, it still rises nicely and makes a beautiful loaf!

    I tried this. I made it at 9:30 one night. Next morning bread had not risen at all. So, I watched and waited all day. Next morning, roughly 34 hours later, it had double in size. Decided to proceed. I shaped, put in loaf pan and let rise to top of pan (3 hours) brushed with egg wash and everything bagel, and baked. Not bad for 100% whole wheat. It does taste sour. Next time I think I’ll use all purpose flour, or a mixture of both. The slow rise might have been caused by my starter which was only 25 days old. I had fed it the day before. The day I was making the bread, I let it set on counter until it had risen before I mixed anything.
