Sunflower and Sesame Sourdough Bread

Every once in a while, a bread comes along that surprises you with its wholesomeness. Add in a little more whole grains, a few handfuls of nutritious seeds, a little sweetness from natural honey, and with sufficient natural fermentation, the result is a loaf that tastes as good as it is healthy. Nutty sunflower seeds—something I’ve surprisingly often overlooked in my baking—and my often-used and never under-appreciated sesame seeds are a winning combination I need to turn to more often. And this sunflower and sesame sourdough bread is so easy to put together! The loaf has the flavor of these rich seeds, in concert with the dash of mellow and warming honey, makes for a delightful loaf.

I just love eating my way through a slice of this bread. Toasting takes the whole package up a notch, making it—especially the crust—crunchy like a boot through fresh, crisp snow left overnight to harden. There’s something a seed soaker brings to a loaf that seems to conjure this crunchiness; whether it’s the water in the soaker or the seeds themselves, it has the potential to turn me into a seed fanatic. I mean, it is easy to add them into a dough, and their nutrition is always welcome—perhaps I should do it more often.

The flavor of sunflower seeds will always remind me of summers spent digging through bags of salt-covered shells, cracking each one to get the prized kernel. They’re an addictive lot, these seeds, a snack for mindless consumption. I always found myself quickly polishing off an entire bag before realizing I’ve even started. That is, until the inevitable salt overload kicks in, compelling you to chug a few bottles of water and swear next time you’ll take it easy. But of course, you don’t. And the wonderful cycle repeats.

I’ve since curbed my appetite for salted sunflower seeds, but my appreciation for their flavor never left. This bread is chock full of the tasty little morsels, and roasting them beforehand amplifies their nutty flavor. The 30% whole grain in the formula brings an earthiness that works well with the added seeds, and I could see going even higher to bring even more flavor.

Let’s first look at how to prepare the sunflower and sesame seeds.

Choosing and preparing sunflower and sesame seeds

I used roasted and unsalted sunflower seeds from the market, but raw, unsalted sunflower seeds with a quick toast—10 minutes should do it—in the oven at 350°F (175°C) would work well. Roasting/toasting the seeds amplifies their nutty (isn’t it interesting we say sunflower seeds have a nutty flavor when they’re seeds?) flavor.

I’m a huge sesame seed fan, and I always have a jar of white and black sesame seeds in my pantry ready to be used on the outside of any loaf. I prefer using white sesame seeds on the outside; when they are toasted in the oven while the bread is baking, they take on a deliciously subtle nutty flavor. By contrast, black sesame already has a vibrant flavor thanks to its dark hull. Because of this, I prefer to use them mixed into a dough (and the look is quite striking!).

This recipe uses a seed soaker to prepare the black sesame seeds, which have their hull intact. Soaking seeds like this for a time period helps to soften them and make them more palatable. The water for the soaker is taken from the overall hydration of the formula. This way, no unaccounted for water is added to the recipe.

Sunflower and sesame sourdough bread schedule

Baking schedule

This sunflower and sesame sourdough bread is made over the course of two days. Cold proofing this dough brings additional flavor, but as always, a same-day bake can be done as well. Instead of placing the shaped dough into the refrigerator to proof overnight, leave it out, covered, to proof for 1-3 hours (depending on kitchen temperatures) until ready to bake.

Sunflower and sesame sourdough bread method

1. Prepare the levain – 9:00 a.m.

This is a relatively fast levain, ripening in five hours. Mix the following ingredients in a container and leave covered to ripen at a warm temperature, about 76-78°F (24-25°C) for 5 hours.

WeightIngredientBaker’s Percentage
27gMedium-protein bread flour or all-purpose flour50.00%
27gWhole wheat flour50.00%
27gRipe sourdough starter50.00%

2. Prepare the seed soaker – 9:10 a.m.

To soften the seeds and make them more palatable when eating the final loaf of bread, soak them in boiled water while the levain is ripening, about 5 hours.

Right after making the levain, prepare the seed soaker. Add the 35g black sesame seeds to a heat-proof bowl and pour 35g boiled water over the seeds. Stir to combine and ensure all the seeds have been wet. Cover the bowl and let rest until called for in bulk fermentation.

3. Autolyse – 1:00 p.m.

This recipe uses the autolyse technique to increase the extensibility of the dough and make mixing by hand easier. In a small way, the increased extensibility also helps with incorporating the seeds.

Add the following to a mixing bowl and mix until incorporated. Let the mixture rest, covered, for 1-hour.

587gMedium-protein bread flour or all-purpose flour
236gWhole wheat flour
542gWater 1 (this is the remaining water 1 after taking some for levain and soaker)

4. Mix – 2:00 p.m.

Gather the following ingredients for mixing. The remaining water (water 2) should only be added through mixing and kneading if your dough feels like it can handle the addition. Use a splash to work in the levain and salt, adding the rest if the dough feels cohesive.

44gWater 2
16gFine sea salt
137gRipe levain (from step 1)

I strengthened this dough by hand using the slap and fold kneading technique, which quickly develops the dough. Alternatively, you could use a bread dough mixer, or even a KitchenAid would work with this dough.

Add the honey and levain to the top of your dough already in the mixing bowl, and use a splash of the reserved water to moisten. Mix the levain thoroughly and slap and fold (or do folds in the bowl) for 5 minutes until the dough begins to smooth out and become elastic.

Let the dough rest in the mixing bowl for 10 minutes.

Sprinkle the salt over the dough, then dissolve with a splash of the reserved mixing water. Mix thoroughly. If the dough still feels very slack, continue to strengthen the dough in the bowl by stretching and folding (or do slap/fold on the counter) for a few minutes until it begins to tighten and come together.

Dough at the end of mixing

As you can see above, at the end of mixing, expect this dough to be rather firm, smooth, and elastic. Hold back the sesame and sunflower seeds until just before the first set of stretch and folds during bulk fermentation.

Transfer the dough to a container for bulk fermentation and cover.

4. Bulk fermentation – 2:15 p.m. to 5:45 p.m.

At warm room temperature, around 74-76°F (23-24°C), bulk should take about 3 1/2 hours. If your kitchen is cooler, place your bulk container in a small home dough proofer, or extend the bulk fermentation time to give the dough more time to ferment. This dough needs about three sets of stretch and folds during the 3-hour bulk.

Combine the 132g sunflower seeds and the black sesame seed soaker (approximately 70g) in a large bowl.

Before you give your dough its first set of stretch and folds, spread about 1/4 of the mix-ins over the top of the dough. Then, grab one side of the dough and stretch it up and over the dough to the other side. Spread on another 1/4 of the mix-ins to the new top. Rotate the bowl 180° and perform another stretch and fold. Spread on another 1/4 of the mix-ins, then rotate the bowl 90° and do another stretch and fold. Finally, spread on the last of the mix-ins, turn the bowl 180° and do one last stretch and fold. It would be best to have the dough neatly folded up in the bowl with all the mix-ins tucked into the dough.

The remaining two sets of stretch and folds should be more gentle. After the third set, let the dough rest, covered, for the remainder of bulk fermentation.

5. Divide and preshape – 5:45 p.m.

First, check on the dough in the bulk fermentation container. This dough can be sluggish if the dough temperature came in below the FDT listed in the recipe, or it cooled during bulk fermentation. If the dough looks flat, shaggy, and doesn’t jiggle some when you shake the bowl, give it another 15 minutes and check again.

Fill a bowl with some water and place it on your work surface. Scrape out your dough from the bulk container onto your dry counter. Divide the mass in half using a bench knife. Using a wet hand and the knife in the other, gently preshape each half into a loose round.

Let the dough rest (also called a bench rest), uncovered, for 35 minutes until its relaxed outward. Because this dough was strong and firm for me, a slightly longer rest period of 35 minutes was helpful (see why in my guide to preshaping bread dough).

6. Shape – 6:20 p.m.

I like to shape this sunflower and sesame sourdough bread as a batard shape, but a round boule would also work well. Shape each by first flouring the top of the rested rounds and your work surface, flip the dough over to the floured space, and then shape them into your desired shape.

This sunflower and sesame sourdough bread is wonderful topped with white sesame seeds. Spread out a thin layer of seeds on a clean kitchen towel or on a sheet pan. After shaping the dough into a batard or boule, roll it, smooth side down, on the seeds so they stick.

After each dough piece is shaped and optionally topped with seeds, place it seam side up in a proofing basket lined with canvas or a clean kitchen towel.

7. Proof – 6:30 p.m. to 9:00 a.m. (overnight)

Cover the baskets with a large, reusable plastic bag and seal it shut. Place the baskets into your refrigerator to proof overnight.

8. Bake – 9:00 a.m. (next day)

Preheat your oven with a baking stone or Baking Steel inside to 450°F (230°C).

I baked these loaves in my Challenger bread pan, but you could also follow my guide to steaming an oven for baking bread.

Score each piece of dough and slide it into the oven—bake for 20 minutes with steam. Then, remove the steaming pans from inside the oven (or remove the lid to your baking pan) and bake for an additional 30 minutes, or until the crust is deeply colored and the interior temperature registers around 204°F (95°C).

Once fully baked, cool your loaves on a cooling rack for 1-2 hours. See my post on the best way to store bread to keep it fresh for a week or longer.

This delicious sourdough bread is chock full of healthy roasted sunflower seeds and black sesame, finished off with a touch of honey. The sunflower seeds bring a rich, nutty flavor, and the umami-forward sesame adds depth and complexity. A wonderful bread for lunch, dinner, or any snack!



  • 27g medium-protein bread flour or all-purpose flour
  • 27g whole wheat flour
  • 55g water
  • 27g ripe sourdough starter

Seed Soaker

  • 35g black sesame seeds
  • 35g water, boiled

Main Dough

  • 587g medium-protein bread flour or all-purpose flour
  • 236g whole wheat flour
  • 132g sunflower seeds, unsalted and roasted
  • 35g honey
  • 16g sea salt
  • 542g water 1 (autolyse)
  • 44g water 2 (reserved for mix)
  • 137g levain


  • White sesame seeds to top dough (optional)


  1. Levain (9:00 a.m.)
    In a small container, mix the Levain ingredients and keep it at a warm temperature for 5 hours.
  2. Prepare soaker (9:10 a.m.)
    Right after making the levain, prepare the seed soaker. Add the soaker ingredients to a heat-proof bowl. Cover the bowl and let rest until called for in bulk fermentation.
  3. Autolyse (1:00 p.m)
    In a medium mixing bowl, add the 587g medium-protein bread flour, 236g whole wheat flour, and 542g water 1 and mix until no dry bits remain. Cover the bowl and let rest for 1 hour.
  4. Mix (2:00 p.m.)
    To the mixing bowl holding your dough, add the honey and levain and a splash of water. Mix thoroughly and strengthen the dough for about 5 minutes. Let the dough rest for 10 minutes in the mixing bowl. Add the salt, another splash of water, and mix until incorporated. Strengthen the dough further if necessary until it’s elastic and smooth. Transfer the dough to a bulk fermentation container and cover.
  5. Bulk Fermentation (2:15 p.m. to 5:45 p.m.)
    This dough will need 3 sets of stretch and folds during bulk fermentation. First, mix together the soaked and cooled sesame seeds with the sunflower seeds. Before you give your dough its first set of stretch and folds, spread about 1/4 of the mix-ins over the top of the dough. Add the rest of the mix-ins in the same way through the remaining folds for the first set. Perform two more sets of gentle stretch and folds during this 3 1/2 hour period, then let the dough rest the remainder of bulk fermentation.
  6. Divide and Preshape (5:45 p.m.)
    Lightly flour your work surface and scrape out your dough. Using your bench knife, divide the dough in half. Lightly shape each half into a round shape. Let the dough rest for 35 minutes, uncovered.
  7. Shape (6:20 p.m.)
    Shape the dough into a round (boule) or oval (batard) and roll in the white sesame seeds to top, if desired. Then, place the dough in proofing baskets.
  8. Proof (6:30 p.m. to 9:00 a.m. the next day)
    Cover proofing baskets with reusable plastic and seal shut. Then, place both baskets into the refrigerator and proof overnight.
  9. Bake (The next day, bake at 9:00 a.m.)
    Preheat your oven with a baking surface or combo cooker/Dutch oven inside to 450°F (230°C).

    When the oven is preheated, remove your dough from the fridge, score it, and transfer it to the preheated baking surface or combo cooker. Bake for 20 minutes with steam. After this time, vent the steam in the oven or remove the lid (you can keep it in the oven or remove it) and continue to bake for 30 minutes longer. When done, the internal temperature should be around 204°F (95°C).

    Let the loaves cool for 2 hours on a wire rack before slicing.

What’s Next?

Sometimes it’s the simplest approach to baking that yields the best loaf. I originally started this recipe with a complex blend of flours, seeds, and other additions and, through testing, slowly pared it back until just the essentials remained. While I’m all about exploring different ingredients and techniques (like sift and scald) to see if they yield an improvement, oftentimes, great sourdough bread is simply beginning with a strong starter, using good flour, attention to detail, and a few seeds you might already have in the pantry.

If you liked this sunflower and sesame sourdough bread but want to take it even further with more additions, check out my seeded sourdough, which is chock full of seeds (including flaxseed) and also sure to delight.

Buon appetito!
