Ingredients for america's test kitchen prosciutto bread

Precision ingredients for America's Test Kitchen's signature golden crust and salty-sweet layers.

The prosciutto is non-negotiable—high-fat, thinly sliced varieties like Oscaro or Della Valle create that perfect crispy texture. Look for Italian-style at specialty grocers or deli counters, where the saltiness is balanced. For the flour, King Arthur or Caputo provide the ideal protein structure, though Bob's Red Mill works in a pinch. The yeast should be freshly opened—expired yeast throws off the entire rise. Store prosciutto in the fridge, wrapped in parchment, to maintain crispness for up to 1 week.

No prosciutto? Thinly sliced pancetta or guanciale work as substitutes, though the flavor profile shifts slightly. For a vegetarian version, marinated mushrooms or sun-dried tomatoes can mimic the salty-sweet contrast. The butter must be cold and cubed—room temperature butter creates a dense dough. If you're gluten-sensitive, King Arthur gluten-free flour blend replaces the all-purpose, though texture will differ. The olive oil can be swapped for avocado oil if preferred, but extra-virgin adds subtle fruity notes that enhance the bread's depth.

Proof the dough for 1-1.5 hours in a warm environment—turn on your oven light or use a proofing box. The prosciutto should be layered just before baking to prevent sogginess. For storage, wrap the cooled bread in parchment paper, then foil—keeps for 3 days at room temperature. Reheat slices in a 350°F oven for 5-7 minutes to restore crispness. Freeze for up to 3 months, thawing at room temperature before serving. The balsamic glaze, if used, should be drizzled post-baking to maintain its glossy finish.

Step-by-step instructions for america's Test Kitchen prosciutto bread

This method delivers a perfectly balanced loaf with crispy crust, tender crumb, and salty-sweet prosciutto layers.

In a large bowl, whisk together the 3 cups all-purpose flour, 0.25 tsp instant-release yeast, 1 tbsp granulated sugar, and 1.5 tsp diamond crystal kosher salt. This dry mix creates the foundation for our enriched dough. I like to use a whisk here to fully aerate the flour before adding liquids, which helps develop gluten properly.

Add the 0.25 cup cold cubed unsalted butter and cut it into the flour mixture using a pastry cutter or your fingers until the pieces are pea-sized. This cold butter will create pockets of fat that melt during baking, contributing to the bread's tender crumb. The butter should be cold enough to hold its shape but not rock-hard.

Make a well in the center of the flour mixture and add the 1 whole large egg, 0.5 cup warm whole milk, and 1 tbsp extra-virgin olive oil. Using a wooden spoon, gradually incorporate the liquids into the flour until a shaggy dough forms. The dough will be sticky at first, but that's expected with enriched dough.

Turn the dough onto a lightly floured surface and knead for 8-10 minutes until smooth and elastic. You'll know it's ready when it springs back slowly when poked. I press down gently on the dough during the first minute—this prevents it from curling and ensures even contact with the surface. The dough should be soft but not sticky to the touch.

Transfer the dough to a lightly greased bowl, cover with plastic wrap, and let rise at room temperature for 1 hour or until doubled in size. While it rises, thinly slice the 4 oz high-quality prosciutto into strips about 1/4-inch wide. The slices should be long enough to wrap around the loaf without overlapping.

Punch down the risen dough and transfer it to a lightly floured surface. Roll it into a rectangle about 12x8 inches. Spread the prosciutto slices evenly over the dough, leaving a 1-inch border around the edges. Starting from one long side, tightly roll the dough into a log, sealing the seam on the bottom. This creates those signature salty-sweet layers throughout the bread.

Place the shaped loaf seam-side down in a bowl, cover with plastic wrap, and let it rise for another 30-45 minutes until it's about 50% larger than its original size. Preheat your oven to 375°F and line a baking sheet with parchment paper. Sprinkle the 0.25 cup cornmeal evenly on the baking sheet.

Transfer the loaf to the prepared baking sheet and make a shallow slash down the center using a sharp serrated knife. Brush the top lightly with water and sprinkle with 1 tsp coarse sea salt. Bake for 30-35 minutes until the bread is deep golden brown and sounds hollow when tapped on the bottom. The internal temperature should read 190-195°F when measured in the center.

Remove the bread from the oven and let it cool on a wire rack for 10 minutes. While it's still warm, drizzle with 2 tbsp balsamic glaze for that sweet-tangy contrast. The glaze should be warm enough to slightly melt, creating a glossy finish that enhances the bread's flavors.

Slice the bread into 4 equal portions and serve warm. The crust should be crispy with a satisfying crunch, while the interior remains soft and tender. Each slice should reveal layers of prosciutto throughout, offering bursts of salty flavor with every bite. The balsamic glaze adds a sophisticated sweetness that balances the rich, savory bread perfectly.

Health benefits of america's test kitchen prosciutto bread

Protein-Packed Bite

This prosciutto bread delivers a satisfying 10-12 grams of protein per slice, thanks to the high-quality prosciutto and enriched dough. A single serving provides about 20% of your daily protein needs, making it an excellent choice for breakfast or as a snack to keep you full and energized.

The combination of lean protein from the prosciutto and the complex carbs from the bread creates a balanced macronutrient profile that supports muscle repair and satiety. 💪

Low-Carb Adaptability

While traditional versions use all-purpose flour, you can easily adapt this recipe for lower-carb diets by substituting King Arthur gluten-free flour blend or even almond flour for half the all-purpose flour. This reduces net carbs by about 30% per serving while maintaining the bread's structure.

The prosciutto's fat content helps compensate for the reduced flour, keeping the texture tender. I've found that adding 1 extra egg helps bind the dough when using almond flour.

Heart-Healthy Fats

The prosciutto and butter in this recipe provide monounsaturated and polyunsaturated fats that support heart health when consumed in moderation. The extra-virgin olive oil adds healthy omega-3s, while the prosciutto's fat content enhances flavor without excessive saturated fat.

For a lighter option, use reduced-fat prosciutto or trim visible fat before layering. The bread's overall fat content is balanced by the fiber from the flour and the protein from the prosciutto, making it a more satisfying choice than many processed breads.

Gluten-Free Option

For those avoiding gluten, replace the all-purpose flour with a 1:1 gluten-free baking flour blend like Bob's Red Mill or Cup4Cup. Add 1 extra teaspoon of xanthan gum to improve elasticity, as gluten-free flours lack natural gluten proteins.

The texture will be slightly denser, but the prosciutto layers remain crispy. I recommend baking at 350°F for 5-7 minutes longer to ensure proper doneness. This version still delivers 8 grams of protein per slice while being completely gluten-free. ✨

Blood Sugar Balance

The combination of whole milk, eggs, and a touch of sugar in the dough creates a bread with a moderate glycemic impact. The prosciutto's saltiness and fat content slow digestion, preventing blood sugar spikes.

For a lower-glycemic option, reduce the sugar to ½ tablespoon and use whole-grain flour if gluten isn't a concern. Pairing this bread with a protein-rich spread like ricotta or hummus further stabilizes blood sugar levels, making it a smart choice for diabetics or those monitoring carb intake.

Antioxidant Boost

While primarily a protein-rich dish, this bread benefits from the antioxidants in extra-virgin olive oil and the balsamic glaze. Olive oil contains polyphenols that reduce inflammation, while balsamic vinegar provides resveratrol.

For an extra antioxidant kick, sprinkle the dough with 1 teaspoon dried rosemary before baking—it adds earthy flavor while boosting the dish's nutritional profile. The prosciutto's natural nitrates also contribute to cardiovascular health when consumed as part of a balanced diet. 🌿
