Ingredients for america's test kitchen italian bread

Precision ingredients for bread that rivals Italian bakeries—no shortcuts, just science-backed quality.

The flour is non-negotiable here. King Arthur or Caputo bread flour gives that perfect chewy crumb, but Bertolini from Italian markets takes the prize for authenticity. If you're using all-purpose, add 1 tbsp extra flour—it won't have the same protein structure. The yeast? Fresh is best, but store-bought works if it's been stored properly (test it first in warm water). For the olive oil, California avocado oil is a great neutral alternative if you prefer a milder flavor. Room temperature water is key—cold water slows fermentation, hot water kills yeast.

No bread flour? All-purpose plus 1 tbsp vital wheat gluten gets you close. Short on yeast? Active dry yeast works at the same amount, but instant activates faster. The sugar can be swapped for honey (reduce by 10%) if you prefer, but it won't caramelize the crust as beautifully. For shaping, flour-dusted hands work too, but ice water creates that signature tension. Pro tip: If your kitchen's humid, chill the dough 10 minutes before shaping—it'll be easier to handle.

Dough keeps 24 hours in the fridge, wrapped tightly. For longer storage, freeze shaped loaves for 3 months—thaw at room temp before baking. The cornmeal layer? Don't skip it—it prevents sticking and adds that crisp base. Fresh-baked bread? Cool completely on a wire rack (never on a towel)—it prevents sogginess. Slice with a serrated knife for clean cuts, and store leftovers wrapped in a beeswax wrap for extra freshness.

Step-by-step instructions for science-backed Italian bread

Here's how to achieve that perfect crusty exterior and tender crumb—every time.

In a large bowl, whisk together the 3.5 cups bread flour, 0.25 tsp instant yeast, 0.5 tsp granulated sugar, and 1.5 tsp salt. This high-protein flour gives structure, while the sugar kickstarts yeast activity. Create a well in the center and pour in the 0.5 cup olive oil and 1.5 cups water at room temperature. The olive oil adds flavor and helps develop gluten.

Using a wooden spoon or dough whisk, gradually incorporate the liquids into the dry ingredients, mixing until a shaggy mass forms. Let it rest for 5 minutes—this allows the flour to fully hydrate and gluten to begin forming. After resting, knead the dough by hand on a lightly floured surface for 8-10 minutes until smooth and elastic. You'll know it's ready when it springs back slowly when poked. If it feels sticky, add flour 1 tablespoon at a time—but don't overdo it, or the bread will be dense.

Shape the dough into a loose ball and place it back in the bowl, covering it tightly with plastic wrap or a damp towel. Let it ferment at room temperature (70-75°F) for 1.5 to 2 hours, or until it has nearly doubled in size. This bulk fermentation develops flavor and creates a light, airy crumb. You'll see bubbles forming on the surface and hear a slight hollow sound when you tap the dough.

Real talk: Don't rush this step. The longer the fermentation, the more complex the flavor—think nutty, slightly tangy notes. If your kitchen is cooler, give it an extra 30 minutes. The dough should feel soft and slightly jiggly when gently pressed. Once it passes the "poke test," it's ready for shaping.

Turn the dough onto a lightly floured surface and divide it into 4 equal pieces (about 8 ounces each). Shape each piece into a smooth, taut ball by pulling the dough toward you in a rolling motion. This creates surface tension, which helps the bread hold its shape during baking. Place the shaped dough on a parchment-lined baking sheet, cover with a damp towel, and let it proof for 30 to 45 minutes at room temperature.

During proofing, the dough should rise 50% to 75% of its height. It should feel springy to the touch and leave a slight indent when pressed gently with a finger. Here's the thing—if the dough springs back too quickly, it needs more time. If it feels limp or doesn't hold its shape, it's overproofed. The goal is a balance where the dough is fully active but still responsive.

Preheat your oven to 450°F with a baking stone or inverted baking sheet on the middle rack. Once preheated, sprinkle the 0.25 cup cornmeal evenly over the baking sheet—this prevents sticking and adds a subtle crunch. Place the shaped dough balls on the cornmeal, spacing them 2 inches apart. For extra steam (key for that crispy crust), pour 0.5 cup ice water into a small baking dish and place it on the lower oven rack 5 minutes before baking.

Bake the bread for 20 to 25 minutes until the crust is deep golden brown and sounds hollow when tapped on the bottom. The internal temperature should reach 190°F to 195°F. Don't open the oven during baking—this causes the bread to collapse. If the tops brown too quickly, tent loosely with aluminum foil. The bread is done when it pulls away from the sides of the pan and has a crisp, shatterable crust.

Remove the bread from the oven and transfer it to a wire rack to cool for at least 30 minutes. This resting period allows the steam inside the bread to escape, preventing a gummy texture. The crust will firm up as it cools, and the crumb will become light and airy. Slice with a sharp serrated knife for clean cuts—never a bread knife, or you'll crush the structure.

Serve the bread warm for the best experience. The crust should be crisp enough to stand up to a knife, while the interior remains soft and chewy. Store leftovers in an airtight container at room temperature for 2 days or freeze for up to 3 months. For extra flavor, brush the warm bread with olive oil and sprinkle with flaky sea salt before serving.

Creative variations of this america's test kitchen italian bread

Rosemary Garlic Twist

Add 1 tbsp finely chopped fresh rosemary and 2 minced garlic cloves to the dough during the initial mix. The rosemary infuses the bread with a fragrant, piney aroma, while the garlic adds depth that pairs perfectly with Italian dishes.

I like to add these to the olive oil first, letting them steep for 5 minutes before mixing into the flour. For extra intensity, use 1 tsp rosemary extract but reduce water by 1 tbsp to maintain dough consistency. 🌿

Olive Oil Encrust

After shaping but before proofing, brush the dough balls with an extra 1 tbsp olive oil mixed with ½ tsp flaky sea salt. This creates a golden, flavorful crust that's irresistible. For a more dramatic effect, sprinkle coarse kosher salt or crushed red pepper flakes on top before baking.

I often do this with California avocado oil for a neutral base that lets the salt shine. The crust becomes shatteringly crisp while maintaining a soft interior. 🧂

Whole Wheat Substitution

Replace 1 cup of the bread flour with whole wheat flour for a nuttier, heartier loaf. The texture will be denser but still delicious. To compensate for the extra moisture in whole wheat, reduce water by 1 tbsp.

I recommend King Arthur whole wheat flour—it has a lighter texture than some brands. For best results, increase bulk fermentation time by 30 minutes to allow the whole wheat to fully hydrate and develop flavor. 🌾

Cheesy Italian Focaccia

Divide the dough into 2 pieces instead of 4, then shape each into a 12x8-inch rectangle on a parchment-lined baking sheet. Press your fingers into the dough to create dimples, then top with ½ cup shredded mozzarella and 2 tbsp chopped sun-dried tomatoes.

Drizzle with 2 tbsp olive oil and bake as directed. The result is a chewy, focaccia-style bread perfect for dipping in balsamic or olive oil. 🧀

Herb & Seed Topping

After the first 10 minutes of baking, sprinkle the loaves with a mix of 1 tbsp sesame seeds, 1 tbsp poppy seeds, and 1 tsp dried oregano. This adds texture and visual appeal while complementing the bread's flavor.

For a savory-sweet twist, add 1 tbsp honey to the seed mixture before sprinkling. The seeds toast beautifully in the oven, creating a delightful crunch. 🌰

Freezer-Friendly Shaped Loaves

Shape the dough into loaves as directed, then place them on a parchment-lined tray. Freeze uncovered for 2 hours until solid, then wrap individually in plastic wrap and store in a freezer bag for up to 3 months.

When ready to bake, remove from the freezer and let thaw at room temperature for 1 hour before proceeding with the baking instructions. The cold dough bakes more evenly, ensuring a perfect crust every time. ❄️
