Easy Multigrain Sourdough Bread Recipe

Filled to the brim with grainy goodness, this easy multigrain sourdough bread recipe is everything you want in grainy bread. It's totally customisable so you can add the seeds and whole grains you love to eat, you can even add whole wheat flour if you prefer it.

This multigrain sourdough has the perfect blend of seeds and smells absolutely amazing! It's definitely a seeded multigrain sourdough bread, however you can definitely customise the different grains and seeds you include.

There really is something so wholesome about multigrain bread. Perhaps something we didn't love as kids, becomes somewhat of an adult treat. The smell of this hearty loaf baking is just out of this world!

I worked over a number of weeks to perfect the ratio of grains to bread flour to ensure that this sourdough bread maintained a soft, fluffy crumb, a crispy, chewy crust and a big pop of oven spring - even jammed with all that grainy goodness!

And if you love all things whole grain and seedy, why not try making these seedy sourdough crackers or this whole wheat rye sourdough loaf or sourdough oatmeal loaf. They're all tried and tested in The Pantry Mama Kitchen!

What Makes Sourdough Bread "Multigrain"?

Multigrain bread can be defined as bread made with 2 or more types of grain (source). This means that you really only need 2 types of grains (for example you could use wheat flour and rolled oats), however most breads using the "multigrain" title will contain more than 2 grains and also include some seeds as well.

Multigrain bread, sourdough or otherwise, is different to whole wheat bread, in that whole wheat bread is using only one type of grain.

There are definitely health benefits to eating multigrain bread and in particular, sourdough multigrain bread - including increased digestibility, lower GI levels and less blood sugar spikes.

The sourdough multigrain bread in this recipe could be classified as more of a seeded multigrain sourdough bread due to the inclusion of seeds.

How To Make Multigrain Sourdough Bread

This sourdough recipes is fairly easy, even if you're a beginner sourdough baker. The recipe follows the same sequence as a plain sourdough loaf, just with the inclusion of soaked seeds. I have documented the entire process here, as well as in the recipe card at the bottom of the page.

You'll need an active sourdough starter that has been fed and is at it's peak to make this multigrain bread recipe successfully. I have used a kitchen scale to weigh out all ingredients accurately.

Before You Start:

Before you start this bake, you'll need to soak your seeds and oats in about 100g of water.

Only soak pumpkin, sunflower, flax and oats (not poppy seeds, sesame seeds or hemp). Just leave them for around an hour.

They will soak up all of the water in this time.

Autolyse:

Weigh out your sourdough starter and water into a large bowl.

Mix the water and starter together briefly. Then add your flour and salt and mix altogether with a silicone dough scraper.

The dough will be fairly shaggy and only just brought together (see photo).Cover your bowl with cling film or a damp tea towel and let it sit for around 1 hour.

Adding Your Seeds:

After the dough has been through autolyse you will need to add your seeds. If there is still water sitting in the bowl of seeds, drain it off. The seeds will be quite wet but this will help them incorporate into the dough.

Put all the seeds and oats into the middle of the bowl and work your way around, folding the dough over the seeds and oats and incorporating them into the dough.

Don't worry if your seeds haven't worked through the dough fully, they will be evenly distributed when you complete the stretch and folds.

Once the dough has formed into a ball, pop the cling film back on and let it rest for 30 minutes.

Stretch & Folds:

Over the next few hours you need to create some structure for your dough by "stretching and folding". Aim to do around 4-6 sets of stretches and folds. For each set, stretch the dough up and over itself 4 times. Leave around 15 minutes in between each set. You do not have to be exact with time, but you need to do at least 4 sets over 2 hours.

Bulk Ferment:

Once you've finished your stretch and folds, place the plastic wrap or damp tea towel back over your dough and let it ferment at room temperature until it has doubled (you can read more about understanding when bulk fermentation has finished here).

Shaping Your Dough:

Once your dough has finished its first ferment, it's time to form it back into a ball and give it some shape and surface tension. You'll need to flour your counter top with rice flour for this (we use rice flour because it has no gluten). Try to be quite sparing with the rice flour, you only need a very light dusting.

Use a silicone dough scraper to gently ease the dough out of the bowl. You want it to land upside down on your counter so that the smooth top of the dough is on the countertop and the sticky underside is facing up. This will make it easier to shape.

You want to pull the edges of the dough into the centre and then flip it over so that the sticky side is now underneath. Using the stickiness, gently pull the dough into a tight ball.

Adding Topping:

You will need a banneton to put your dough into. If you do not have a banneton, then a bowl or basket lined with a floured tea towel is perfectly fine. Make sure your bowl isn't too big though, you want your dough to retain some shape. You can find plenty of banneton alternatives here.

Whatever you're using needs to be liberally floured with your rice flour. Then, add the seeds you'd like on the top of your sourdough to the bottom of the banneton.

Place your dough, seam side up into the bannton.

This will allow the seeds to stick to the top of the dough, so when you flip it out to bake, they won't all fall off.

Cold Ferment:

Now your dough is in it's "shaping container" cover it loosely with a plastic bag or damp tea towel and place into the fridge. I use a large plastic bag to cover it - I just reuse it each time. It's not totally essential to cover it - you can place it in the fridge uncovered if you'd prefer.

Try to leave it in the fridge for a minimum 5 hours up to a maximum of around 36 hours. The longer you leave it the better your bread will be! A longer cold ferment creates beautiful blisters on your crust and a deeper sourdough flavour. It will also ensure your dough forms a skin which makes it easier to score. For this multigrain bread, I highly recommend leaving your dough in the fridge for 36 hours - it creates the most amazing flavor!

Preparing to Bake:

Once you're ready to bake your sourdough, you'll need to preheat your oven to 230C/450F.

Place your Dutch Oven into the oven when you turn it on so it gets hot. Try to preheat for around 1 hour to ensure your oven is super hot - but you know your oven so just adjust this time if you need to. Leave your dough in the fridge until the very last minute - placing a cold dough into a hot oven will give you a great "spring".

Scoring Your Sourdough:

Now it's time to score! When your oven is at temperature, take your sourdough out of the fridge. Gently flip your dough out onto a piece of parchment paper so that the seeded top is facing up.

Make sure that you make the baking paper big enough to use the edges as a handle to lower to dough into your Dutch Oven.

Gently score your bread with a lame, clean razor blade or knife. At minimum a large cross is sufficient, but you can get as artistic as you like (although it can be hard with a seeded loaf). You can read more about how to score sourdough bread here.

Baking Your Sourdough:

Carefully take your dutch oven out of the oven. Place the sourdough into the hot Dutch Oven using the baking paper as a handle. Put the lid on and place into the hot oven. If you want to you can spritz your dough with extra water before you put the lid on.

If you're worried about the bottom of the bread burning or being too chewy, place a baking sheet on shelf underneath your Dutch Oven - it works!

BAKE TIME:

30 Minutes with the lid on at 230C/450F plus

10-15 Minutes with the lid off at 210C/410F

Finishing Your Bake:

When you remove your dough from the oven, carefully remove it from the dutch oven as soon as possible and place on a wire rack to cool.

What Grains and Seeds to Use?

I tried many different seed and grain combinations before I settled on the ones I've listed in my recipe. I like the combination of grains and seeds so I used:

• 25g Whole Rolled Oats
• 25g Pumpkin Seeds
• 25g Sunflower Seeds
• 25g Rolled Flax Seeds
• 10g Hemp Seeds
• 10g Sesame Seeds
• 10g Poppy Seeds

You can use any combination of grains and seeds you'd like. Aim for around 100 to 150g of whole grains and seeds. It's a great way to use up those random packs of seeds lurking in your pantry! There's really no hard and fast rules for the grains you can inlclude. Some other whole grains and seeds you could include are quinoa, cracked wheat and steel cut oats.

You can also use seeds on the outside of the loaf. To do this, place the seeds into the base of the banneton before placing the shaped sourdough on top. The seeds will stick to the dough as it proofs.

Baker's Timeline for Multigrain Sourdough Bread

This is a sample baker's timeline that you could use for this multigrain sourdough loaf. You can adjust it to suit your own schedule or you can learn how to create your own baker's timeline for sourdough here.

DAY 1

1.00pm - Feed sourdough starter

5.00 pm - Premix and Autolyse (this is also a great time to soak your seeds)

6.30pm - Form into a smooth ball. Rest for 30 minutes.

7.00pm - Perform 4-6 sets of stretch & folds over next 2 hours.

9.00pm - Cover and leave on bench overnight for bulk ferment if temp right.

DAY 2

6.00am - Shape & lift into banneton/bowl & into the fridge.

2.00pm - Place into a hot oven and bake until golden brown.

7.00pm - finally cut into delicious sourdough and slather with cultured butter!

Soak Your Seeds

I like to soak the oats, pumpkin, flax and sunflower seeds for about 30 minutes before I put them into my bread. The seeds will absorb all the water in the dish.

The flax will become quite gelatinous but they will be perfect once cooked.

Soaking the seeds ensures that they don't burn but I feel that it also helps them to incorporate into the dough much more easily too.

I find that if you don't soak the seeds, they will absorb some of the moisture from your dough once they are incorporated and this can make your dough harder to work with as it will be a lower hydration.

If the seeds do soak up some of the water in your dough, it will result in a tougher crust and a smaller crumb. Of course, the bread will still be delicious, but if crust and crumb are important to you, then I highly recommend soaking the seeds.

Just remember to drain them before adding to the dough as you don't want to have a sloppy dough with too much hydration.

Using Whole Wheat Flour

You can use whole wheat flour in this loaf if you prefer. I recommend not using more than 50% whole wheat flour, along with the different types of grains and seeds.

Halving the amount of bread flour and replacing with whole wheat flour may not give you the oven spring you like. If you are having trouble with the oven spring when using whole wheat flour, you might consider adding some vital wheat gluten for a boost to your bread dough.

Serving Ideas for Multigrain Sourdough Bread

This multigrain sourdough bread can easily be used where you would use a normal white loaf. It is soft and fluffy and makes the most delicious cold cut sandwiches.

I love to eat it toasted in the mornings with lashings of peanut butter and jam. It's fantastic topped with poached eggs and hollandaise sauce!

I love making my toddler multigrain sourdough toast for breakfast because I feel good giving him all those extra seeds in his morning meal. He's quite happy to eat this - unlike my older kids who prefer this invisible multigrain sourdough bread.

This yummy, wholesome sourdough is slathered with homemade cultured butter (seriously you have to try it).
