This multigrain sourdough bread is going to be your new favorite! Crunchy crust, soft and chewy inside, and nutty flavor from whole grains, it is perfect for toast, grilled cheese, and so much more!
Using multigrain hot cereal is an easy way to get a variety of grains without having to buy multiple bags of ingredients.

I have always been a big fan of hearty whole grain bread, even as a kid. And my favorite white bread is sourdough. So of course I had to combine the two into one loaf.
I am now obsessed with this bread, and so is my family. My daughter, who usually turns up her nose at anything that isn’t white bread, declared this multigrain loaf the best bread I’ve ever made!
We go through it so fast that I can’t even keep up, and there are days we completely run out before I have enough start to make a new batch. It’s that good!
You can completely adapt it by adding your favorite types of grains and seeds. It’s one of the tastiest ways you can add more whole grains to your family’s diet!
Is multigrain sourdough bread healthy?
Yes, it’s a very healthy bread! Not only do you get the benefit of the prebiotics and probiotics from the fermentation of the sourdough, you have the added fiber and nutrients from the grains and seeds.
In addition, it’s lower in fat and sugar than most bread recipes, and is lower on the glycemic index.
How to make sourdough multigrain bread:
- PREP – Bring the water to a boil in a small saucepan. Add the cereal and quinoa; let cool for at least 10 minutes while you start combining the other ingredients.

- COMBINE – In a large bowl, preferably with a lid, stir together the warm water, active starter, honey, wheat flour, and 2 cups of the bread flour.

- AUTOLYZE – Let the wet dough sit at room temperature for about 30 minutes. The flour will absorb some of the water, and the gluten will start to develop.
- STRETCH & FOLD – Stir in the salt, pepitas, and enough flour to make a soft but slightly sticky dough. Knead slightly in the bowl to make a round ball. Fold one corner of the dough over to the other side. Rotate the bowl a quarter turn and fold over each of the corners. Repeat this process 2-3 more times, using wet hands to prevent the dough from sticking.

- BULK FERMENTATION – Cover the bowl with a lid or plastic wrap. Chill overnight, or for 12-15 hours.
- SECOND RISE – The next day, let the bowl of dough sit at room temp for about an hour. Use wet hands to form it into a loaf; place it seam side down on a piece of parchment paper. Let the loaf rise for 2-4 hours in a warm place.
- BAKE – Place a 4 quart Dutch oven in your oven and preheat your oven to 450°. Use a bread lame to cut slits across the top of the bread dough. Spritz with water and sprinkle the oats and sesame seeds over the top.
Transfer the loaf to the hot pan. Place 3-4 ice cubes between the parchment and the pan. Add the lid and bake for 45 minutes. Remove the lid and bake for another 10-15 minutes. 
- COOL – Carefully remove the loaf from the pan by holding the parchment corners. For cleanest slices, cool completely.
We can never wait for the bread to cool before digging in! I love it warm with butter or peanut butter. YUM!

It also makes fantastic grilled cheese sandwiches. I think I could eat one every day!

VARIATIONS:
- If you don’t have bread flour, all purpose flour will work, your bread just won’t be quite as soft and fluffy.
- You can replace some or all of the wheat flour with rye flour.
- I love using pumpkin seeds, but you can use sunflowerseeds, sesame seeds, poppy seeds, flax seeds, chia or hemp seeds. You can even use a combination.

Multigrain Sourdough Bread Recipe
Ingredients
- ⅔ cup boiling water
- ⅓ cup multigrain hot cereal
- 2 Tbsp dry quinoa
- 1 ½ cups warm water
- 1 cup active sourdough starter
- 2 Tbsp honey (or pure maple syrup)
- 1 cup whole wheat flour
- 3 ½ cups bread flour (more or less)
- 2 tsp salt
- 3 Tbsp pepitas (or shelled sunflower seeds)
Topping:
- 1 tsp oats
- ¼ tsp sesame seeds (or poppy seeds)
Instructions
- Combine boiling water, cereal mix, and quinoa; let sit for 10 minutes.
- In a large bowl, combine the warm water, active sourdough start, honey, wheat flour, and 2 cups of the bread flour. Stir until smooth.
- Cover and let sit for 30 minutes at room temperature. Stir in the salt and pepitas, then add 1 1/2- 2 cups more bread flour, enough to make a sticky dough.
- Cover and let the dough rest for 30 minutes, then use wet hands to fold one side of the dough over to the other side. Continue stretching and folding each of the other three sides across the dough. REPEAT THIS PROCESS TWO – THREE MORE TIMES, until the dough is very stretchy.
- Cover the bowl and place the dough in the fridge overnight, or for 12-15 hours.
- Let the dough sit at room temperature for about an hour, then use wet hands to form it into a ball. Place it on a piece of parchment paper.
- Let the loaf sit at room temperature for 2-4 hours, or until it has doubled. (This will take longer if your kitchen is cool.)
- Preheat your oven and a 4 quart dutch oven to 450°. Cut slits in the top of the dough with a bread lame or sharp knife. Spritz with water and sprinkle the oats and sesame seeds over the top.
- Carefully lift the parchment and dough and place in the hot Dutch oven. Place 3-4 ice cubes between the parchment and the pan.
- Add the lid. Bake for 45 minutes at 450 degrees with the lid on. Remove the lid and bake for another 10-15 minutes, or until the crust is golden brown and the internal temperature is around 195°.
- Carefully use the parchment to remove the bread from the pan and place it on a wire rack. Let cool for at least 20 minutes – if you can wait that long! It does slice best after it has cooled completely.
Notes
- I’ve made this bread with both 5 grain and 7 grain hot cereal from Bob’s Red Mill. Any hearty multigrain hot cereal should work.
- If you like an extra crunchy crust, you can remove the lid sooner and bake it longer uncovered.
