There is nothing quite like a loaf of delicious sourdough bread. And this wholesome recipe is nourishing and filling.

This is a take on my sourdough sandwich bread, but with the added benefit of whole grains.

The recipe uses a combination of all-purpose flour and multigrain cereal. I find that the combination of the two adds an extra flavor and texture to the bread that you just can’t get from using one alone.

The bread is also surprisingly mild and has a hint of sweetness, yet still has the same soft texture of a traditional sandwich loaf. The end result is a comforting, satisfying, and unique loaf that you and your family will love.

Made with simple ingredients, this hearty multigrain sourdough bread recipe makes a lovely sandwich, side, or toast for morning eggs.

Health Benefits Of Sourdough

Fermenting grains increases the nutritional content of the grain. The fermentation process activates enzymes, which can make the nutrients in the grains more absorbable to us. It can also reduce the amount of antinutrients in the grains, such as lectins, which can otherwise block the absorption of vital nutrients.

This makes it possible for our bodies to derive even more nutrition from each bite of grain-based foods. Plus, it lowers the gluten content and increases digestibility.

In addition to the health benefits, fermenting grains also adds a unique flavor and texture to your food, making it more interesting and enjoyable.

FAQ:

Is multigrain sourdough bread healthy?

Yes. Packed full of fiber, iron, vitamins, minerals, protein, and more, sourdough bread is a healthy choice. The fermentation process also reduces the glycemic index so blood sugar won’t spike as much as regular bread.

Is sourdough healthier than whole grain bread?

Yes. Since it contains more nutrients, is easier to digest, and has a lower glycemic index, sourdough bread is considered healthier than whole wheat or white bread.

Can I bake this in a dutch oven?

Yes. After the dough has doubled in size, shape and place in towel lined bowl or basket. Cover with plastic and place in the fridge for 12-15 hours. The next day, preheat the oven with the dutch oven at 500 degrees for 1 hour. Add dough to parchment paper and score. Place in the hot dutch oven, cover with a lid and bake for 20 minutes, remove lid and bake for another 20 minutes or until crust is golden and crusty.

How To Make Sourdough Multigrain Bread:

four process pictures of creating multigrain sourdough bread in a stand mixer. First picture of a package of multigrain cereal. Top right: soaking multigrain cereal in water. Bottom left: adding remaining ingredients to the cereal in a stand mixer bowl. Bottom right: Kneaded multigrain bread dough

Place cereal mix in a large bowl or bowl of stand mixer. Pour boiling water on top.

Let the mixture cool for about an hour until it reaches room temperature. Make sure it isnโ€™t too hot, so it doesnโ€™t kill the yeast in your starter!

Add the rest of the ingredients to the mixer and knead with the dough hook on medium speed until the dough comes together, pulls away from the sides of the bowl, and passes the window pane test. This can take a very long time, sometimes up to 20 minutes. Knead it until it is a smooth and glossy dough. Base the time on how the dough feels.

You could also use the stretch and fold method if you don not have a stand mixer.

Follow the first two steps above. Then proceed with stretch and folds.

First 3 stretch and folds – every 15 minutes.

Last 3 stretch and folds – every 30 minutes.

Cover with a damp towel, lid, or plastic wrap and proceed to the next step.

Bulk ferment until doubled. The bulk fermentation time may take anywhere from 4-8 hours depending on the temperature in your house.

The warmer the environment the faster the fermentation process. Make sure not to over ferment. If you need to pause the fermentation, or slow it down, because itโ€™s bedtime or you have another obligation, place it in the fridge for up to 24 hours.

Shape the bread:

Butter or line with a piece of parchment paper a 9ร—5 inch loaf pan.

Shape by rolling the dough flat into a rectangle and rolling it up.

Add to parchment lined or buttered loaf pans.

Second Rise

Cover with a towel or plastic wrap for 2-4 hours at room temperature, or until doubled.

When the dough is about ready to bake, preheat the oven to 375 degrees.

Optional: Crack an egg into a small bowl and whisk together. Using a pastry brush, brush the top of the dough with the egg wash and sprinkle with a small amount of oats if desired.

Bake for 45 minutes, or until golden brown on top.

Allow to cool completely before slicing.

Bakerโ€™s Schedule

8:00 pm: Feed sourdough starter with flour and water. Depending on how active your sourdough starter is, it could take between 4-12 hours for it to be active enough to bake a loaf of bread.

8:00 am: If the sourdough starter is nice and bubbly, then proceed to creating the dough. Add multigrain cereal to the stand mixer bowl and add hot water.

9:00 am: If the multigrain cereal is cool enough, add the rest of the ingredients and create the dough. Let the dough rise for 4-8 hours.

1:00-5:00 pm: Shape the dough and place into the prepared loaf pan. Let the dough rest for 2-4 hours or until it has doubled in size. If the timing is off and the dough hasn’t risen enough before bed, just stick it in the fridge covered with plastic.

3:00 pm-9:00 pm: Preheat oven. Brush the egg wash and sprinkle oats on the top of the bread dough, if desired. Bake

    I am currently making this bread. My sourdough starter is quite young so admittedly I added a very small amount of yeast. This recipe is almost the same as the non-sourdough bread I make on a regular basis. Hoping this is just as good – but better!

    Couldnโ€™t believe how simple this was using the stand mixer. Absolutely delicious sandwich loaf bread. As suggested in the comments, I scored it down the middle .Donโ€™t rush the baking. Had to leave mine a few more minutes as I tested the internal temp and it wasnโ€™t ready at the 45 min mark. Glad I waited. It was perfection. Made one yesterday and making a second one right now so we can take it on our road trip tomorrow! Thanks for a keeper!

    This was actually my first time making sourdough bread. It turned out great tasting but while baking the side blew out and it looks like the loaf had a goiter. I did it in a bread pan with egg wash and oats. Should I have scored it? When I make again that’s probably what I’ll do. It really is a delicious mulitgrain bread! And so soft!!!
    Thanks for making me confident enough to even try!

    1. Lisa Bass says:

      Yes, scoring helps some of the air to escape.

    I can never use just one recipe. ๐Ÿซฃ but followed mostly yours and it turned out great! Thank you!

  5. Barbara says:

    I made this tonight & doubled the recipe. Dough is VERY sticky!!! I have to knead by hand as I donโ€™t have a mixer which makes it even more messy. Used a scraper to get the dough off my counter & back into the bowl for bulk ferment.

    Weโ€™ll see what happens overnight with the rise, but Iโ€™m hopeful. I have it in the fridge until I go to bed for now hoping one it rises overnight & two it doesnโ€™t over ferment.

    As mentioned in a different post I may need to adjust my water amounts going forward.

    1. Lisa Bass says:

      Sometimes it needs a bit of resting to develop a structure and hold its form.

      1. Barbara says:

        Still very sticky with overnight ferment to the point is oozed over the sides of the bowl. However I put some four down on counter to make it a bit easier to handle & place in bread pans. 2nd rise went great, so I baked as is. They turned out great & moist โค๏ธ
        Made another batch last night & adjusted water for double batch to 2 1/4 cups & added a touch more starter. Much easier to handle & about to put in oven. Hope this batch turns out just as soft & delicious!!

    I love all your other loaf breads and I am about to make this. So unlike your other breads, this doesnโ€™t bulk ferment for 10-12 hours? Can I bulk ferment for 10-12 hours with this recipe like the whole wheat and traditional sourdough recipes?

    1. Lisa Bass says:

      Yes, that is fine. Or you can put it in the fridge to long ferment.

    Iโ€™ve tried several recipes for sourdough; and this, by far, is my favorite. Easy, flavorful, super soft, and consistent product. Iโ€™ve made several times and will continue to do so. Pay attention to the farmhouseonboone conversion table for accurate gram weights.

    This bread is excellent! The wonderfully easy recipe produces a very large loaf, that rises beautifully (if you are patient), and has a perfect texture for multigrain bread. It took about 6 hours for the first rise (after keeping it in the fridge overnight), and then about 2 hours for the second rise (in a warmed up bathroom)Just polished off a giant , warm crusty end (with the butter dripping); canโ€™t wait to see how it tastes in a fancy grilled cheese.
    My daughter has also made the sourdough sandwich loaf, and it was also amazing!
    Thank you so much for sharing your knowledge and recipes ๐Ÿ˜ƒ canโ€™t wait to try a few more!
