Soft, fluffy sourdough sandwich bread. Oh this is what dreams are made of! I’ve made so many loaves of this bread lately. I’ve turned it into avocado toast, BLTs, and just simply gifted it to friends because that’s how I roll. I have all the step by step photos, tips and tricks for you to master this soft sourdough sandwich loaf at home.

I’ve been pretty obsessed with baking with mySourdough Starter these past few months stuck at home. It’s like part science. Part magic. And 100% holy moly deliciousness. In fact I created this free e-mail series, Sourdough Simplified to help you get started making sourdough and take away some of the confusion.

I’ve been baking up thisSourdough Bread Recipe (From Starter!) about once a week. I’ve ventured out to make someSourdough Brioche Bread to make crazy good french toast. SomeWhole Wheat Sourdough Sandwich Bread to make amazing sandwiches each day. And let’s not forget about the weekends. Those are reserved for what might be the BESTSourdough Cinnamon Rolls I have ever eaten.

So this time, a soft sourdough sandwich white bread. Because this is what all sandwiches deserve.

Ok but let’s back it up a bit. Maybe you’re new to sourdough.

What Is Sourdough?

Sourdough is basically an ancient way of making bread. Sourdough doesn’t rely on commercial yeast (aka those little packets you have bought at the store), but on wild yeast. Wild yeast is everywhere around us and even on us!

By simply combining flour and water, you create a live fermented culture from the wild yeast found on the grains of the wheat that the flour is made from. The more it is “fed”, meaning fresh flour and water, allows the wild yeast to multiply.

Because sourdough relies on wild yeast, the process can take much longer than commercial yeast bread recipes. But the complex flavor and texture is far superior of any other bread you will ever eat.

Is Sourdough Bread Better For You?

Yes. 1000% yes. Sure at first glance, the nutrition label might look the same to conventional bread. But the long fermentation process is what has sourdough sailing past the conventional bread loaves by a mile for its health benefits. Plus it’s made with just a few simple ingredients compared to store-bought bread that has added chemicals and preservatives.

Whole grains, in general, that bread is made with can contain lots of great minerals. But the body can have a hard time absorbing those minerals due to phytic acid that is present in grains. But the lactic acid created from the fermentation process helps to break down the phytic acid allow your body to be able to absorb more of those minerals than you would be able to with bread made from commercial yeast.

Also, sourdough bread can be much more easily digested and enjoyed, especially those with a gluten sensitivity. The long fermentation process helps to already start the process of breaking down the gluten in the bread making it much easier to digest.

So more vitamins, minerals, and it’s easier to digest. Basically, sourdough is awesome.

Make Your Sourdough Starter…

If you haven’t gotten around yet to making your sourdough starter then let’s get going! What are you waiting for? It will take about 5 days to make your starter before you can attempt this bread. But it will be worth it. Here is the full guide onHow To Make Sourdough Starter From Scratch.

Once you have your starter raring to go then you will need tofeed and mantain your starter.

Want to jump in to sourdough but don’t want to make your own starter? Totally fine! Just buy a sourdough starter and it will be ready to use in a couple days.

Ingredients Needed

The best part about this sourdough sandwich bread is that it requires very few ingredients. I think that’s what I love about making sourdough anything! Just simple, real ingredients. Six ingredients. That’s it!

• Sourdough starter
• Water
• Sugar
• Flour
• Salt
• Oil

Ingredient Notes

• Water – I have made this with my tap water no issues, but if you’re concerned about the quality of your tap water then use filtered or bottled water to be safe.
• Flour – I used a combination of bread flour and all purpose which gives it great structure and a soft loaf at the same time. You can use 100% AP flour but the bread may be harder to shape.
• Salt – Different types of salt can vary by weight. I used kosher salt for the best pure salt taste.
• Oil – I use a neutral tasting oil such as canola or vegetable oil but I think any oil would work here like grapeseed or olive. I haven’t tested it without coconut oil, however.

Start With An Active Starter

You want to make sure to start with an ACTIVE STARTER.An active starter is a starter that has doubled in size and you use it when it’s at it’s peak of rising. This is usually about 4 hours after feeding it (if you have been storing the starter in your fridge then it may take a couple feedings to get the starter to an active bubbly stage where it doubles in size within 4 hours).

The time it takes for it to double in size can vary depending on water temperature and room temperature. Warmer = rises faster. Colder = rises slower.

How can you tell when your starter is ready?

I have two ways:

1. The Rubberband trick

Place a rubberband around your starter jar where the height of the starter starts when you feed it. And then when you see it’s doubled in size, it’s ready! Like so…

Update: You can also use a sharpie to mark the outside of your jar! Will wash right off!

2. The Float Test

Still not sure? Take a spoonful (just be careful to not deflate the bubbles) and place in a bowl of water. Does it float? If it does, then you’re ready! If it doesn’t let the starter continue to bubble away before using it.

Making The Sourdough Sandwich Bread Dough

1. Ok now that your starter is ready time to make that dough! You want to first stir together your active starter, water, sugar and oil.
2. Then go ahead and stir in your flour and salt. It will be quite shaggy at first. I stir with a fork then I just get in there with my hands. Nothing. More. Satisfying.
3. Cover with a damp towel for about an hour then work into a smooth ball. I do this by bringing the edges up to the center and the flip it over. And let the dough rise, at room temperature for 8 to 10 hours. I prefer doing this overnight!

Shaping The Dough

Now you can let the dough rise all day and bake it up at night, or start the dough in the P.M. like I do and then it’s ready to be shaped and baked the next morning. No way is wrong. Do what works for you.

1. About 8-10 hours have passed and it’s doubled in size it’s time to shape the dough.
2. Shaping the dough is pretty simple. I just scrape the dough onto a lightly floured counter. Then just dimple the dough with your fingertips to release any air bubbles.
3. Roll the dough into a log and tuck the ends. Let it hang out for about 5-10 minutes to let the gluten relax. And then tighten the shape with your hands. Just cup the dough and pull it toward you.
4. And then it’s time to place it in an oiled loaf pan to go through a second rise!

Final Rise

You want to place the dough into an oiled loaf pan. Be sure to cover your dough. And now it needs to rise for another 1 1/2 – 2 hours until the dough rises about an inch above the rim of the loaf of the pan.

This time can vary depending on how warm your kitchen is. The colder the kitchen the longer it will take! Ideally, the bread would rise in a warm kitchen, about 75oF. You can always put your bread somewhere warm, or try putting it up high too – like above your fridge is always a good spot.

Time To Bake!

Once the dough has risen, it’s time to bake! I bake my loaf in a 375^oF oven for about 40-45 minutes.

Gorgeous loaf of sandwich bread is almost yours…

Recipe Tips

• Make sure your starter is active before you start.Drop a small piece in a bowl of water to see if it floats. It it does, then it’s ready! If not, then it may need 1-2 more feedings.
• Measure Your Flour Using A Kitchen Scale . You can use measuring cups but for best accuracy it’s better use a kitchen scale and weigh out your flour. This ensures you don’t overmeasure, which can result in dense rolls. You can read my post onHow To Measure Flour here.
• Use A Large Mixing Bowl! This dough will expand quite a bit. So the bigger the better.
• Use a damp towel. You don’t want the dough to dry out on top creating a film that will prevent the dough from rising.

Why Didn’t My Sourdough Sandwich Bread Rise?

1. Starter Wasn’t Ready: This could be because your sourdough starter wasn’t quite bubbly and active enough. Be sure to do the “float test” before you begin.
2. Cold Kitchen: Another culprit could be a cold kitchen! If your kitchen is cold the bread will take longer to rise. Ideally, your kitchen should be around 70°F.
3. Overproofed: Another reason I found as I continue on this sourdough journey, is you overproofed your dough. If you overproof then there will be nothing left for it to do, and you will get no rise. So when you place the risen dough in the pan, make sure to not let the dough rise for more than 2 hours. The only exception is if your kitchen is super cold and it’s still not puffy.
