Gluten Free Sourdough Sandwich Bread
A labor of love: San Francisco inspired, gluten free sourdough sandwich bread. Wow – this is one recipe that is so easy to make, but took so long to figure it out. Why? Because we are picky! Also, the perfect sourdough starter takes time to nurture and develop. The best sourdough bread starts with a balanced and properly hydrated sourdough starter. The story continues with an awesome gluten free bread recipe. We paired our starter with Flour Farm’s Family Favorite Gluten Free Bread recipe. If you are a sourdough fan, you will love this bread!
San Francisco Inspired Sourdough Starter – What You Need to Know
We modeled our starter after Bread SRSLY’s brown rice sourdough starter. (That company’s sourdough bread is rockin’ San Francisco!) It’s best to use unfed sourdough starter in this recipe. We “stress” our starter by not feeding it for about 18 hours before using in order to for the bread to have that distinctly “sourdough” flavor. Active starter should appear bubbly, cracked and domed on the surface, and smell pleasantly sour.
Additionally, the sourdough starter in this recipe calls for the starter to be 100% hydrated. This means that equal parts flour and water are fed to the starter by weight, not volume. For example, starter is fed four ounces of flour and four ounces of water to keep it active. If your starter is not balanced in this manner, your results will vary. Also, superfine brown rice flour was used as the grain base for the starter in this recipe.
Sourdough Sandwich Bread Machine Instructions
We have a Cuisinart Bread Maker; however, this recipe should work in any bread machine with a Gluten Free option. Soak the gums as usual and whisk the wet ingredients together in a separate bowl (except the sourdough starter.) Blend the dry ingredients as usual, except leave out the yeast. Place the gums, egg mix and sourdough starter in the pan for the machine. Then add the dry blend on top and smooth it out. Finally, sprinkle the yeast over the dry mix. Set the program to gluten free for the appropriate sized loaf. Scrape down the sides, and fold in any unmixed flour after the initial mix, but other than that – no problem! Forget about your loaf until the timer beeps.
Tips for Success
Here are a few suggestions for a happy experience:
- Sourdough starter needs to be room temperature, active, 100% hydrated, and unfed for at least 12-18 hours
- Soak gums for at least 10 minutes before adding to the mix
- Weigh ingredients for best results
- Ingredients should be room temperature (eggs, water, yeast)
- USA Pan Bakeware coated in silicone are our favorite bread pans – we also coat them in oil or Goop for perfect non-stick performance
- Don’t skip the yeast, the sourdough bread will be fairly dense if you do

Before You Dive In – Prep:
- Sourdough should be room temperature, active, unfed, and 100% hydrated
- Warm water to room temperature
- Soak gums
- Bring eggs to room temperature and separate
- Move oven rack to middle rack
- Preheat oven to 375 degrees Fahrenheit (190 degrees Celsius)
- Spray the loaf pan with non-stick spray – try our non-stick Goop
- Optional: Make your own hydration spray with one part oil to five parts water. We like to spray the top of the loaf with this mix before putting into the oven.
Step 1: Add gums to a liquid measuring cup or medium bowl. Whisk in the water. Continue to rapidly whisk for about 30 seconds. The mixture will be a bit lumpy and that’s OK. Set aside.
Step 2: Add egg whites, oil and vinegar to the stand mixer bowl. Secure the bowl on the stand mixer and attach the paddle. Turn the mixer onto medium-low and allow egg whites to mix until frothy – remember, you are not making meringue. We let the machine do its thing while blending the dry mix.
Step 3: In a separate bowl, whisk together the dry ingredients except for the salt. Add the salt and whisk again.
Step 4: With the mixer on low, add the gum mixture and sourdough starter to the egg white mixture. Increase speed to medium and mix for 30 seconds.
Step 5: Turn the mixer to low and spoon in the flour blend. Mix until flour is completely incorporated. Turn the mixer off and scrape down the sides of the bowl if necessary.
Step 6: Turn the mixer to medium and mix for 5 minutes. The dough will resemble a thick batter.
Step 7: Spoon the batter into a prepared loaf pan. Shape the loaf with a spatula dipped in water to prevent the spatula from sticking to the batter. You may have to dip the spatula several times in water to get your desired shape. Score the loaf by cutting three equidistant diagonal slashes across the top. Spray the top with water or a water and oil mixture (see note above) to prevent drying/cracking.
Step 8: Cover the pan with a towel and allow it to sit undisturbed until the dough has risen to the edge of the pan. This could take 30-45 minutes depending on the temperature of your kitchen. Do not let the dough rise higher than the pan, or it will fall in the oven.
Step 9: Bake in the center of a preheated 375 F/190 C oven for 50-60 minutes (the 9 x 5 will take 60 minutes). Check the crust after 40-45 minutes. If the crust appears too brown, tent the loaf with foil.
Step 10: Your loaf is done when the internal temperature is between 205-210 F/96-99 C. Remove from the oven and slide out of the loaf pan on its side half way onto a cooling rack for 10 minutes. Remove loaf from the pan and allow the loaf to cool right side up for several hours before cutting.
To store: After completely cool, wrap in plastic wrap or store in a bread container. Your loaf will stay counter fresh if wrapped or stored properly for up to 3 days. We do not recommend refrigeration. If not using within a few days, its best to slice and freeze.
To freeze: Freeze the whole loaf or cut and freeze individual slices. If you usually only eat a few slices at a time, we recommend placing unbleached parchment between slices or wrapping individual slices in plastic wrap. Thaw on the counter or in the toaster – yum! Freeze for up to one month.
