Sourdough Sandwich Loaf

Sourdough Sandwich Loaf: Soft, Tangy, and Perfect for Everyday Use

When you think of sourdough, the first image that probably comes to mind is a rustic round boule with a thick, crackly crust. While those loaves are beautiful and delicious, sometimes you need a softer, more versatile bread—something that slices easily, toasts perfectly, and works for sandwiches. That’s where this Sourdough Sandwich loaf comes in. It has all the tang and depth of sourdough, but with a tender crumb and softer crust, making it the ideal everyday bread to keep in your kitchen.

The History and Inspiration Behind This Recipe

Sourdough has been around for thousands of years, long before commercial yeast was invented, and it continues to be one of the most beloved styles of bread worldwide. While artisanal round loaves often steal the spotlight, the softer sandwich-style sourdough loaf was developed as a way to make the unique flavor of sourdough more accessible for daily meals. I started baking this style of loaf when I realized I wanted a bread that could do it all—toast, sandwiches, grilled cheese, even French toast. Now, this recipe has become my go-to for weekly baking, giving me the best of both worlds: the unmistakable tang of sourdough with the functionality of classic sandwich bread.

Why You’ll Love This Sourdough Sandwich Loaf

This loaf strikes the perfect balance between flavor, texture, and versatility. It has a light, airy crumb that’s soft enough for a sandwich but sturdy enough to hold fillings without falling apart. The crust bakes up golden and chewy rather than overly hard, making it easier to slice and enjoy every day. Plus, because it’s made with natural sourdough starter, it develops a more complex flavor and stays fresher longer than breads made with commercial yeast.

Fun Flavor Variations For Your Sourdough Sandwich Loaf

Why settle for plain when you can get creative with different flavor combinations:

• Seeded loaf: Add sunflower seeds, sesame seeds, or flax seeds to the dough for extra texture and nutty flavor.

• Herb-infused: Mix in fresh rosemary, thyme, or chives for a fragrant loaf perfect for savory sandwiches.

• Olive loaf: Fold in chopped olives for a Mediterranean-inspired twist that pairs beautifully with hummus or roasted vegetables.

• Cinnamon swirl: Add a ribbon of cinnamon sugar through the dough before baking for a lightly sweet breakfast version.

Serving Ideas For Your Sourdough Sandwich Loaf

This Sourdough Sandwich Loaf is incredibly versatile and can be used in various ways:

• Classic sandwiches: Use it for vegan BLTs or my TTLA, veggie-packed deli sandwiches, or peanut butter and banana toast.

• Breakfast favorite: Toast and top with avocado, jam, or your favorite nut butter for an energizing start to the day.

• Grilled perfection: Make golden, melty vegan grilled cheese sandwiches with this soft but sturdy bread. This pairs perfectly with my vegan creamy tomato soup!

• French toast: Dip slices into a plant-based custard and fry until golden for an indulgent weekend breakfast.

Tips For The Best Sourdough Sandwich Loaf

For the best results, follow these simple tips to perfect your Sourdough Sandwich Loaf every time:

• Use an active starter: Make sure your sourdough starter is bubbly and at its peak before mixing the dough. Follow my guide to sourdough starters!

• Make sure to use some whole wheat flour: Using a mix of all-purpose flour and whole wheat flour gives this bread a great texture and slightly nutty flavor.

• Bulk fermentation matters: Allow enough time for the dough to rise slowly, developing flavor and structure. This bread really needs at least 1o hours.

• Shape tightly: Roll the dough into a snug log before placing it in the loaf pan to help it rise evenly.

• Don’t overbake: Pull the loaf when it’s golden brown and sounds hollow when tapped on the bottom for the perfect crumb.

• Cool completely: Let the loaf cool before slicing to avoid gummy texture.

Sourdough Sandwich Loaf

Soft and tangy plant-based sourdough sandwich loaf that is perfect for everyday use from sandwiches to toast!

Prep Time45 minutes mins

Cook Time45 minutes mins

Rising Time11 hours hrs

Total Time12 hours hrs 30 minutes mins

Course: Bread

Cuisine: American

Keyword: Artisanal, Bread, Sourdough

Servings: 12

Equipment

• Electric Mixer or Stand Mixer Optional
• Mixing Bowl
• Loaf Pan
• Cooling Rack

Ingredients

• 2¼ cups All-Purpose Flour
• ⅔ cup Whole Wheat Flour
• 1 tbsp Cane Sugar
• 1 tsp Sea Salt
• ¼ cup Plant-Based Butter
• ½ cup Active Sourdough Starter*
• 1⅓ cups Water At room temperature

Instructions

• In a large mixing bowl, whisk together the flours, sugar, and salt. Add in the vegan butter and use your hands to "cut" the fat into the flour. You should end up with a sandy texture.
• Once you have a sandy texture, add in the sourdough starter and water. Stir until a dough forms. Once the dough comes together, cover the mixing bowl with plastic or a damp tea towel and let the dough rest for 30 minutes.
• After 30 minutes, knead the dough, either with your hands or a stand mixer fitted with the dough hook, for about 7 to 8 minutes. The dough should be smooth and supple.
• Place the dough back into the mixing bowl and cover it with plastic or a damp towel. Allow it to bulk rise for 10 to 12 hours at room temperature or until doubled in size. Or place the dough in a warm place, about 80℉ for 3 to 4 hours or until the dough has doubled in size.
• After the bulk rise, dump the dough onto a lightly floured surface. Press it into a rectangle and then form it into a loaf. Place it in a greased loaf pan and cover it with a plastic bag for its second rise, this is for an hour. You want it to rise until it is close to or a little above the edge of the loaf pan.
• Halfway through the rising process, preheat your oven to 500°F. Once the bread has fully risen and you're ready to bake it, reduce the oven temperature to 375°F and bake the bread for 45 to 50 minutes.
• Remove the loaf from the oven and allow it to cool for 10 minutes in the pan before removing it to a wire rack to cool completely.
• Store in a bread bag on the counter for up to a week or slice and freeze for up to 3 months
