Ingredients for Tomato Basil Sourdough Bread

This best tomato basil sourdough bread recipe uses simple ingredients that work together to create something extraordinary. You’ll need an active sourdough starter, but everything else is probably already in your kitchen.

What You’ll Need

• Active Sourdough Starter: the foundation of this entire loaf. It needs to be fed, bubbly, and doubled in size before you use it. If yours is straight from the fridge, feed it and wait until it’s active and airy.
• Bread Flour: gives you that chewy, structured crumb because it has more protein than all-purpose flour. You can use all-purpose if that’s what you have, just reduce the water slightly since it absorbs less liquid.
• Warm Water: activates the starter and brings the dough together. Room temperature or slightly warm works best, not hot or it’ll kill the yeast.
• Salt: controls fermentation, strengthens gluten, and brings out all the flavors. Don’t skip it or your bread will taste flat.
• Tomato Paste: adds concentrated tomato flavor and that gorgeous orange-red color throughout the loaf. This is what makes this tomato sourdough bread recipe so visually stunning.
• Sun-Dried Tomatoes: create little pockets of sweet, intense tomato taste. Chop them small so they distribute evenly. You can also use tomato purée or roasted fresh cherry tomatoes if that’s easier.
• Fresh Basil: brings herbaceous brightness and classic Italian flavor. Dried basil works in a pinch, but use only a tablespoon since it’s more concentrated. Fresh oregano or parsley also work.
• Roasted Garlic: adds sweet, mellow garlic flavor without being overpowering. To roast it, cut the top off a garlic head, drizzle with olive oil, wrap in foil, and roast at 400°F for 40 minutes. In a hurry? Use 1/2 teaspoon garlic powder mixed with a little olive oil.
• Olive Oil: adds richness and keeps the crumb soft. It also helps incorporate the roasted garlic paste into the dough smoothly.

Instructions for Making Tomato Basil Sourdough Bread

Step-by-Step Directions

Step 1: Roast the Garlic Cut the top off a garlic head to expose the cloves. Drizzle with olive oil, wrap in foil, and roast at 400°F for 40 minutes until soft and golden. Let it cool, then squeeze out the cloves and mash them into a paste.

Step 2: Mix the Dough and Stretch and Fold In a large bowl, mix your active sourdough starter with warm water until dissolved. Add the bread flour and mix until no dry flour remains. Let it rest for 30 minutes (this is called autolyse and it helps develop gluten). Add the salt, tomato paste, and roasted garlic, mixing until combined. Over the next 3 hours, perform 4 sets of stretch and folds every 45 minutes. During the last two sets, gently fold in the chopped sun-dried tomatoes and fresh basil. This technique builds dough strength without heavy kneading and is key to making sourdough tomato basil bread with great texture.

Step 3: Bulk Fermentation Cover the bowl and let the dough rise at room temperature for 8-12 hours, or until it’s doubled in size and looks puffy with visible air bubbles. The timing depends on your kitchen temperature. Warmer rooms ferment faster.

Step 4: Shape and Cold Ferment Turn the dough out onto a lightly floured surface. Gently shape it into a round or oval loaf, being careful not to deflate all those beautiful air pockets. Place it seam-side up in a floured banneton or bowl lined with a towel. Cover and refrigerate for 12-24 hours. This slow, cold fermentation develops more flavor and makes the dough easier to score. Don’t skip this step, it’s what gives you that amazing oven spring.

Step 5: Bake Preheat your oven to 450°F with a Dutch oven inside for 30 minutes. Turn the dough out onto parchment paper, score the top with a bread lame or sharp knife, and carefully place it in the hot Dutch oven. Bake covered for 30 minutes, then uncovered for 20-25 minutes until deep golden brown.

Step 6: Cool Let the bread cool on a wire rack for at least 1 hour before slicing. I know it’s hard to wait, but cutting too early makes the inside gummy.

Hint: For the best oven spring, make sure your dough is cold from the fridge when it goes into the hot Dutch oven. The temperature shock creates that beautiful rise and crispy crust.

My Tomato Basil Sourdough Bread Journey

I started making sourdough about five years ago when Grandma handed me a jar of her 30-year-old starter and said, “Jazzy, this is older than you and twice as reliable.” I was terrified I’d kill it. For the first month, I made the blandest, densest loaves you’ve ever seen. But Grandma just kept eating them with butter and telling me they were “getting there.”

One summer when tomatoes were everywhere in her garden, she suggested we try adding them to the dough. I thought she was crazy. But we chopped up some sun-dried tomatoes, mixed in fresh basil from her windowsill, and somehow created this gorgeous, flavorful loaf that made the whole house smell incredible. She looked at me and said, “See? The bread tells you what it needs. You just have to listen.” Now every time I make this tomato basil sourdough loaf, I think about that summer and how she taught me that the best recipes come from experimenting and not being afraid to try something new.

Substitutions for Tomato Basil Sourdough Bread

If you need to adjust this sun-dried tomato sourdough bread recipe to work with what you have, here are some substitutions that actually work.

Sun-Dried Tomatoes: Use tomato purée or an extra 2 tablespoons of tomato paste if you can’t find sun-dried tomatoes. Fresh cherry tomatoes work too, just roast them first to remove excess moisture.

Fresh Basil: Dried basil works in a pinch, but use only 1 tablespoon since dried herbs are more concentrated. Fresh oregano or Italian parsley also make great substitutes.

Bread Flour: All-purpose flour can replace bread flour, though your loaf won’t have quite as much chew. Reduce the water by about 25g since all-purpose absorbs less liquid.

Roasted Garlic: Use 1/2 teaspoon of garlic powder mixed with a little olive oil if you’re short on time. It won’t be as sweet, but it’ll still add that garlic flavor.

Variations on Tomato Basil Sourdough Bread

Mediterranean Style: Add kalamata olives, feta cheese, and oregano along with the tomatoes and basil. This creates a savory bread that’s perfect for Mediterranean dishes or alongside a Greek salad.

Cheesy Version: Fold in cubed mozzarella during the last stretch and fold to make sourdough bread with tomatoes and mozzarella. The cheese melts into little pockets of gooey deliciousness that make the best tomato basil grilled cheese sandwiches.

Focaccia Style: Instead of shaping into a loaf, press the dough into an oiled pan after bulk fermentation, dimple it with your fingers, top with cherry tomatoes and basil, and bake at 425°F for 25-30 minutes to create a tomato basil sourdough focaccia.

Equipment for Tomato Basil Sourdough Bread

Dutch Oven: This is essential for creating that crispy, crackly crust. The covered pot traps steam during the first part of baking, which is what gives you that bakery-quality exterior. A 5-quart Dutch oven works perfectly.

Banneton or Proofing Basket: This helps the dough hold its shape during the final rise. If you don’t have one, line a bowl with a well-floured kitchen towel. It works just as well.

Bread Lame or Sharp Knife: For scoring the top of your loaf before baking. Clean scores help control where the bread expands and create that beautiful artisan look.

Kitchen Scale: Sourdough baking is all about precision. Measuring by weight instead of volume makes a huge difference in consistency. Trust me on this one.

Instant-Read Thermometer: The bread is done when the internal temperature reaches 205-210°F. This takes the guesswork out of baking.

Storage Tips for Tomato Basil Sourdough Bread

Room Temperature: Store the bread cut-side down on a cutting board or in a paper bag for 2-3 days. Don’t use plastic, it makes the crust soft and chewy instead of crispy.

Freezer: This bread freezes beautifully. Let it cool completely, slice it, and freeze in a freezer bag for up to 3 months. Toast slices straight from frozen for quick tomato sourdough toast.

Reviving Stale Bread: Sprinkle a stale loaf with water and warm it in a 350°F oven for 10 minutes. The crust crisps back up and the inside softens like it’s fresh baked.

Pro Tip: Day-old tomato basil sourdough bread makes the best grilled cheese sandwiches. The slight staleness helps it hold up to the butter and cheese without getting soggy. Try it with my Sweet Potato Country Dumplings for a cozy fall meal.

Grandma’s Secret for Tomato Basil Sourdough Bread

Grandma always told me, “Jazzy, the secret to great sourdough is cold fermentation.” After you shape your loaf, stick it in the fridge for at least 12 hours, preferably overnight. The cold slows down the yeast but lets the bacteria keep working, which deepens the sour flavor and makes the dough way easier to score. Plus, a cold loaf going into a screaming hot Dutch oven gives you that explosive oven spring and those gorgeous ears on the crust. She also swore by using the bottom oven rack for the first 20 minutes, then moving it up for browning. That bottom heat makes all the difference.
