Ingredients for america's test kitchen prosciutto bread

Restaurant-quality prosciutto bread relies on these 12 essential ingredients for that signature foil-sealed crust and salty-sweet pull.

The flour and yeast form the foundation of this no-knead masterpiece. King Arthur or Caputo Tipo 00 flour yield the best results—higher protein for structure, gluten development without overworking. Yeast must be active dry (not instant) for proper activation with sugar and water. Penzeys or local specialty grocers carry the freshest yeast; check expiration dates as stale yeast fails to activate. The olive oil should be extra-virgin—look for Italian or Spanish varieties with fruity aromas, not the bland supermarket kind. Prosciutto quality is non-negotiable: D'Onofrio or Parmigiano Reggiano Prosciutto from Italian delis deliver that authentic Mediterranean richness. If substituting, high-quality pancetta works but lacks the same delicate saltiness.

No active dry yeast? Instant yeast at half the amount works in a pinch, but timing differs slightly. Short on olive oil? Avocado oil maintains neutral flavor while providing high smoke point. The prosciutto must be thinly sliced (1/16-inch max)—ask your deli counter to slice it professionally. For a dairy-free version, replace the heavy cream in the egg wash with full-fat coconut cream. The cornmeal should be stone-ground for better texture, though regular works fine. Diamond Crystal kosher salt measures differently than Morton's—adjust to 2 tsp Morton's if using. For a richer flavor, add 1 tsp dried rosemary to the dough during mixing. The foil should be heavy-duty aluminum—avoid non-stick or parchment substitutes.

Store the prosciutto in the coldest part of your fridge wrapped in parchment to prevent drying. Yeast lasts 3 months in the freezer if sealed airtight. The dough can be refrigerated up to 24 hours before baking, developing deeper flavor with longer fermentation. Baked loaves keep 3 days at room temperature wrapped in a clean kitchen towel, or 1 week refrigerated in an airtight container. For reheating, wrap slices in foil and warm at 350°F for 5 minutes—this restores that satisfying pull without drying. Freeze unsliced loaves for up to 3 months by wrapping tightly in foil and plastic wrap.

Step-by-step instructions for america's test kitchen prosciutto bread

This method delivers a perfectly risen loaf with a foil-sealed crust that's both crisp and tender.

In a small bowl, combine the 1.5 cups cold water, 0.5 tsp granulated sugar, and 0.25 oz active dry yeast. Let it sit for 5-10 minutes until frothy. This activation ensures your dough rises properly—if it doesn't bubble, your yeast may be inactive, and you'll need to start over.

In a large bowl, whisk together the 4 cups all-purpose flour and 1.5 tsp diamond crystal kosher salt. Create a well in the center and pour in the yeast mixture along with the 0.25 cup extra-virgin olive oil. Using a wooden spoon, gradually incorporate the flour until a shaggy dough forms. This step is critical for even gluten development, which gives the bread its structure.

Turn the dough onto a lightly floured surface and knead for 8-10 minutes by hand, or use a stand mixer with a dough hook on medium speed for 5-6 minutes. The dough should be smooth, elastic, and slightly tacky—if it feels dry, add 1 tsp water at a time until it reaches the right consistency. Proper kneading develops gluten, which traps gas for that perfect rise.

Shape the dough into a ball, place it back in the bowl, cover with a damp towel, and let it rise at room temperature for 1-1.5 hours, or until doubled in size. The dough should spring back slowly when poked—this is your cue that fermentation is working. If the kitchen is cold, extend the rise time to 2 hours to avoid overproofing.

Punch down the risen dough to release air, then divide it into 4 equal portions. Roll each portion into a 12-inch log and arrange them side by side in a 9x5-inch loaf pan lined with parchment paper. The logs should touch but not overlap—this creates a unified loaf with a clean rise.

Unfold the 4 oz thinly sliced prosciutto and arrange it in a single layer over the dough logs, pressing gently to adhere. The prosciutto will infuse the bread with its signature salty-sweet flavor while creating a stunning visual contrast when baked. Cover the pan loosely with a damp towel and let the dough rise again for 30-45 minutes until it expands slightly above the pan.

Preheat your oven to 375°F. Brush the dough with a mixture of 1 whole large egg and 2 tbsp heavy cream, then sprinkle evenly with 1 tsp coarse sea salt. Cut a 12-inch square of the heavy-duty aluminum foil, fold it in half, and place it over the loaf pan, pressing down firmly to create a tight seal. This foil trap steams the bread, resulting in a crisp exterior and tender interior.

Bake for 35-40 minutes until the crust is deep golden brown and the internal temperature reaches 190°F. The foil should be visibly puffed—this indicates proper steam buildup. If the crust browns too quickly, tent the foil with an additional sheet to prevent burning. Remove from the oven and let the bread cool in the pan for 10 minutes before transferring to a wire rack.

Carefully remove the foil and sprinkle the top of the bread with 2 tbsp cornmeal while still warm. This step adds texture and prevents the crust from becoming gummy. Let the bread cool completely before slicing—rushing this step can result in a dense, uneven crumb. The prosciutto will crisp slightly as it cools, enhancing its savory depth.

Slice the bread into 4 equal portions and serve warm. Each bite should deliver a balance of crispy crust, tender crumb, and the unmistakable flavor of cured prosciutto. For best results, store leftovers in an airtight container at room temperature for up to 2 days, or freeze for up to 3 months.

Italian-Inspired Focaccia

Transform your prosciutto bread into a rustic Italian focaccia by shaping the dough into a rectangle on a baking sheet.

After the first rise, dimple the dough with your fingers, then top with 4 oz prosciutto, 2 tbsp olive oil, 1 tsp flaky sea salt, and 1 tsp dried rosemary. Bake at 375°F for 25-30 minutes until golden.

This variation keeps the foil-seal technique but adds a fragrant Mediterranean profile that pairs beautifully with soups or roasted vegetables.

Sweet Honey & Prosciutto

For a sweet-savory fusion, brush the baked loaf with 2 tbsp warm honey after removing the foil. Top with an additional 1 oz prosciutto and let it crisp. The honey caramelizes slightly, creating a sticky contrast to the salty prosciutto.
