Easy Sourdough Sandwich Bread with King Arthur Flour
We love the tangy taste and fluffy interior that classic sourdough bread is best known for having. Not only is sourdough delicious, but it is also one of the easiest baked goods to make from scratch: no yeast, dairy, or eggs are needed!
Sourdough bread is vegan-friendly, there are no eggs or milk, and it’s quite healthy compared to other types of bread. The starter needed to make it contains live and active cultures that help the bread naturally rise. That means that you don’t need any yeast or other artificial rising agents.

Homemade loaves of sourdough bread typically have a crunchy, slightly chewy exterior. However, my no-knead bread recipe uses King Arthur Flour and an easy overnight rise to create a wonderfully light crust and soft bread. The result is a flavorful and tender sourdough that’s perfect for slicing and enjoying as your new favorite sandwich bread.

Ingredients YOu Need to Make This Recipe
Tender sourdough with a perfectly soft crust is easy to make with just a handful of simple ingredients. There’s no yeast, eggs, or milk required!
Here is everything needed for sandwich-worthy soft bread:
- Sourdough starter – active and bubbly
- Water – warmed to 95 to 100 degrees Fahrenheit
- Bread flour – I prefer King Arthur Flour for this soft crust sourdough bread recipe
- Sugar – either granulated cane sugar or your choice of sugar alternative, like coconut sugar
- Extra virgin olive oil and salt

How to Make the Best No-Knead Sourdough Sandwich Bread Dough
This soft crust sourdough bread recipe requires just a few basic steps. Spoiler alert: the overnight rise makes a soft bread that’s far better than anything you’ll find at the grocery store.
Start it on a relaxing Saturday or Sunday evening, and then bake the next day. In no time, the sourdough bread will be ready to slice and stack with your favorite sandwich ingredients.
Follow these steps to make the best no-knead sourdough sandwich bread dough:
- Feed your sourdough starter 12-24 hours before starting this bread recipe.
- In a medium bowl, combine the sourdough starter with warm water, and then add King Arthur bread flour, sugar, oil, and salt. I like using a dough whisk for mixing.
- Mix well to form a shaggy, sticky dough. Tip: Flour or wet your hands and use them to finish mixing the dough. Then cover the bowl with a damp towel and allow the dough to rise 30-45 minutes.
- Next, carefully coax the dough from the bowl and transfer it to a clean and lightly floured surface. Stretch and fold the dough a few times before returning to the bowl. Recover with another damp towel, and now allow the sourdough to rise at room temperature overnight, approximately 8-10 hours.
- In the morning, lightly flour your countertop. Remove the dough from the bowl and gently stretch it to form a rectangle. Use your fingers to dimple the dough to release the air from the dough (as shown in the photo below).

Then roll up the sourdough dough into a log shape. Cover with a damp towel and let the dough rest for about 10 minutes.

How to Bake Soft Sourdough Sandwich Bread
Lightly spray a 9” x 5” loaf pan with nonstick spray. Then tighten the loaf by gently rolling and pulling the dough, and transfer to the prepared loaf pan with the seam side down. Cover with a towel and let the loaf rise for another hour or two, until it has doubled in size.

When you’re ready to bake your sourdough loaf, start by preheating the oven to 375 degrees Fahrenheit. Then bake the bread for 40 minutes, until the crust is a lovely golden brown color. Remove from the oven and allow the bread to rest for 10 minutes before carefully tipping it out of the pan onto a cooling rack.
The sourdough sandwich soft bread should be completely cooled for at least one hour before it is either stored whole or sliced and enjoyed.

How to Store Soft Crust Sourdough Sandwich Bread
Homemade sourdough bread stays fresh for up to 5 days if stored in a plastic bag at room temperature.
For the softest crust, I recommend that you do not put it in the fridge, but you can seal it in an airtight plastic bag and keep it in the freezer for up to 3 months. Allow the bread to defrost at room temperature before slicing and using.

Frequently Asked Questions
Sure, though you will experience a slightly smaller loaf. If you have vital wheat gluten, use 4 cups of all-purpose flour and 4 tablespoons of vital wheat gluten in place of the bread flour.
The sourdough needs a warm area for the bulk (overnight) rise. Find a warm place (75º – 85º F) like an oven with the light on, a warm window, or above the refrigerator or dryer to set the bread for 2 hours
I usually go by baking time, if the top of the loaf is golden, and it if sounds hollow if I tap on it. If you are unsure, if the sourdough bread is fully baked, the internal temperature should be around 195º – 200ºF.
the Full sourdough Soft bread recipe

Soft Sourdough Sandwich Bread (No-Knead)
Equipment
- Bread pan, 9" x 5" - See notes for a 12' x 4.5" pan
Ingredients
- ⅓ cup (65 grams) sourdough starter, bubbly and active (fed within 12-24 hours)
- 1⅓ cups (300 grams) warm water, filtered (95º to 100º F)
- ¼ cup (56 grams) granulated sugar
- 3½ -4 cups (500 grams) bread flour I recommend weighing your flour, see notes for using measuring cups
- 1½ tablespoons (20 grams) extra-virgin olive oil
- 2 teaspoons (9 grams) sea salt
Instructions
- Add the starter to a large bowl. Mix in warm water and sugar, stirring until dissolved. Add bread flour, oil, and salt. Stir with a dough whisk or wooden spoon until a thick, shaggy dough forms.
- Flour your hands, and finish mixing dough by hand until most of the flour has been absorbed. Don't worry if there is flour on the sides or bottom of the bowl. Cover with a clean, damp kitchen towel and let the dough rest for 30 to 45 minutes.
- Coax the dough from the bowl and stretch and fold the dough by stretching 4 inches then pushing it down the middle and turning 1/4 until you make a circle. Return the dough to the bowl, cover with a damp towel, and let rise at room temperature overnight (at least 8-10 hours) until double in size. Do not refrigerate dough.
- In the morning, lightly flour your counter top. Remove the dough from the bowl, gently stretching it into a rectangle, then your fingers to dimple the rough to release the air from the dough (as shown in photo). Roll up dough into a log shape. Cover and let the dough rest 10 minutes.
- Spray bread pan with cooking spray. Tighten the dough log by gently pulling it towards you along the counter top for 5-8". Place it in your loaf pan, seam side down. Cover and let rise for 1-2 hours, until dough has doubled in size. Press the corner edge of the dough in 1/2" and if the indentation remains, it's ready to bake.
- Preheat your oven to 375º. Bake in the center of the oven for 40 minutes. The top of the loaf should be golden in color. After 10 minutes, tilt the pan to remove the bread to cool on a cooling rack. Wait at least 1 hour before cutting (to prevent the loaf from deflating).

Hi! I’m trying your recipe today. Does the bread really need to sit 8-10 hours if in a warm environment? Say 75-80 degree kitchen. I don’t want to over-ferment, so just want to be sure that’s part of the recipe or are we just watching for bulk ferment and may be less in warm kitchen? TY~
Renae says
Yes, it does. I recommend an overnight rise of at least 8 hours. My house is 78ºF overnight and it takes at least 8 hours.
Cyndi Greene says
I really want to try this recipe!! And can’t wait!! I have a great starter, but it is whole wheat (King Arthur). Can I use that with this recipe??
Bec - TFN Team Member says
Hi Cyndi!
Fortunately, we also have a wheat sourdough sandwich bread recipe here on the site as well! Just make that recipe with your King Arthur wheat flour. Wishing you delicious success! 🙂

Haley says
Does the active starter need to be stirred down before measuring it out or does that matter?
Bec - TFN Team Member says
That’s a great question, Haley! Fortunately, because the starter ingredients are measured in grams, it will weigh the same whether it’s been stirred or not. This is another reason that we recommend measuring ingredients on a kitchen scale instead of measuring by volume.
Alexis says
I love this recipie! It’s foolproof for this beginner, I’ve made it twice and both times perfect.
Grace says
I really like this bread! I have my daughter and her friend using this recipe! We all love it! The only thing I would like to ask is there a way to lessen the ‘sourness’ …..yes I know it’s sourdough….and yours is the best tasting! But after a day or two it it seems to be more sour! I have heard that some baking soda that might help….what do you think? And is there anyway to get the bread lighter and fluffier? I use unbleached all purpose flour. I won’t stop making this recipe! 👩🏻🍳
Renae says
The best way to make it less “sour” is to use your starter to make the bread about 12 hours after feeding, before it starts to ferment more in the jar. I don’t recommend adding baking soda to this recipe. A starter that is fed regularly (every day if kept on the counter or every week in the fridge) will make less sour baked goods. It’s all about the acidity. As for the texture, try using a mixture of bread flour and all purpose flour and see if that helps!
Jackie Reynolds says
This is amazing sandwich bread. My husband is a huge fan. To answer a question about the flavor of the bread after the first or second day. My recommendation is to never ever store the bread in plastic Ziploc‘s. I did that for a long time with my other sourdough bread recipes and it never tasted as good the next day unless we toasted it. The problem is that plastic ruins, the flavor of the bread. I now start my bread in bags that I got on Amazon that are paper with a cellophane window. It makes all the difference.

The best way to keep the bread tasting good
Is to Store it and nonplastic bags. Paper is great. I store mine in bags that I bought on Amazon that are paper with a cellophane window.
