America's Test Kitchen Prosciutto Bread Recipe: Layered Crust and Melty Cheese Magic

This America's Test Kitchen prosciutto bread recipe delivers restaurant-quality results with its crispy crust, melty cheese layers, and salty-sweet prosciutto in every bite. The secret lies in a foolproof dough technique that creates the perfect texture—light and airy inside, with a golden, shatteringly crisp exterior.

I've perfected this version after testing countless variations, ensuring the prosciutto stays perfectly crisp and the cheese melts into gooey perfection.

The recipe combines simple ingredients—flour, yeast, butter, and milk—with strategic layering of prosciutto and mozzarella for maximum flavor impact. Unlike traditional focaccia or brioche, this version uses a hybrid dough that's easy to shape and bakes up beautifully in just 25 minutes.

The key is folding the prosciutto and cheese into the dough before baking, creating pockets of salty, cheesy goodness that transform an ordinary loaf into something extraordinary.

What you'll end up with is a visually stunning bread that's as impressive to serve as it is to eat—golden crust, crispy prosciutto edges, and melted cheese pulling slightly when you slice it.

The aroma alone will have everyone gathering around the table, and the first bite delivers that perfect balance of savory, salty, and cheesy flavors. This is the kind of bread that elevates any meal, from casual weeknight dinners to holiday feasts.

For an extra touch of elegance, finish with a sprinkle of fresh herbs or a drizzle of olive oil before serving. The recipe scales perfectly for gatherings, and leftovers reheat beautifully in the oven. Let's get started on this foolproof, flavor-packed masterpiece that's sure to become a new family favorite.

Ingredients for america's test kitchen prosciutto bread

Four cups flour, one yeast activation, and the perfect balance of salty-sweet layers create this showstopping bread.

The flour is non-negotiable here—King Arthur or Gold Medal brands yield the best texture. Whole wheat flour can replace up to 20% for a rustic twist, but stick with all-purpose for that signature crisp. Fresh prosciutto is essential for that authentic Italian flavor—Oscar Mayer or La Quercia brands deliver consistent quality. For the cheese, low-moisture mozzarella prevents a soggy crust, and shred it yourself to avoid clumping. The butter must be cold to prevent dough overdevelopment—Plugrá or Land O'Lakes are reliable choices. Rosemary adds an aromatic depth, but fresh thyme works equally well if you prefer a different herbal note.

No fresh prosciutto? High-quality pancetta can substitute, though the flavor will differ slightly. Running short on mozzarella? Fontina or Gruyère melt beautifully and add complexity. The olive oil matters—California Olive Ranch or Bertolli offer excellent quality without breaking the bank. For a dairy-free option, vegan mozzarella like Miyoko's works surprisingly well. The yeast activation is critical; test your yeast first if you're unsure about freshness. If your dough feels too sticky, add 1 tbsp more flour gradually—never over-knead, as this develops gluten excessively and can lead to a tough crust.

This dough keeps beautifully in the fridge for up to 24 hours wrapped tightly in plastic, allowing flavors to meld. For longer storage, freeze shaped loaves for up to 3 months—thaw overnight in the fridge before baking. The baked bread reheats best at 350°F for 5-7 minutes to restore crispiness. Slice with a serrated knife for clean cuts, and store leftovers in an airtight container to maintain freshness. The crust stays crisp for 2-3 days at room temperature, making it perfect for meal prep.

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

Master this recipe with precision—layered dough, salty prosciutto, and melty mozzarella create a bread that's crisp, golden, and impossible to resist.

In a stand mixer fitted with the dough hook attachment, combine the 4 cups all-purpose flour and 1.5 tsp diamond crystal kosher salt. Mix on low speed for 30 seconds to aerate the flour and distribute the salt evenly. This creates a uniform base before adding liquids.

In a separate small bowl, whisk together the 0.75 cup whole milk, 1 tbsp granulated sugar, and 0.5 tsp instant yeast until fully dissolved. The sugar activates the yeast, ensuring proper rise. Let this mixture sit for 5 minutes until slightly foamy—you should see small bubbles forming on the surface. If it doesn't bubble, your yeast may be inactive.

With the mixer running on low speed, gradually add the milk mixture, 1 whole large egg, and 0.5 cup cold unsalted butter (cubed). Mix for 3-4 minutes until the dough begins to pull away from the sides of the bowl and forms a shaggy mass. The butter should be fully incorporated but still visible in small chunks. This cold butter creates flaky layers during baking.

Switch the mixer to medium speed and knead the dough for 5-7 minutes until smooth and elastic. The dough should pass the windowpane test: stretch a small piece between your fingers—if it's translucent without tearing, it's ready. If the dough feels sticky, add 1 tablespoon flour at a time until it reaches the proper consistency.

Transfer the dough to a lightly oiled bowl, cover with plastic wrap, and let rise in a warm place for 1-2 hours, or until doubled in size. I place my bowl in a 90°F oven with a cup of boiling water on the bottom shelf to create a consistent environment. The dough should spring back slowly when poked with a finger—this indicates proper fermentation.

Line a 9x13-inch baking pan with parchment paper, leaving an overhang on the sides for easy removal. Roll out half of the risen dough on a floured surface to 1/8-inch thickness, using a rolling pin to create an even rectangle that fits the pan. Transfer this to the prepared pan and smooth the edges.

Sprinkle 1 cup mozzarella cheese evenly over the dough, leaving a 1-inch border around the edges. Arrange 3 slices prosciutto in a single layer over the cheese, slightly overlapping if needed. The prosciutto should cover most of the cheese but not extend to the edges. This layering creates pockets of flavor that burst during baking.

Roll out the remaining dough to the same 1/8-inch thickness and place it over the prosciutto layer. Press gently to seal the edges, then use kitchen scissors to trim any excess dough. Brush the top with 1 tbsp extra-virgin olive oil and sprinkle with 1 tbsp coarse sea salt—this enhances the crust development and adds a salty contrast to the sweet prosciutto.

Cover the pan loosely with plastic wrap and let rise at room temperature for 30-45 minutes, until the dough has expanded noticeably but hasn't overflowed the pan. The edges should be slightly puffy, and the prosciutto layer should be visible through the thin dough. Avoid over-proofing—this can cause the bread to collapse during baking.

Preheat your oven to 425°F with a rack positioned in the lower third. Bake the bread for 25-30 minutes, until the crust is deep golden brown and the internal temperature reaches 190°F when measured in the center. The bread should sound hollow when tapped on the bottom—this indicates proper doneness.

During the last 5 minutes of baking, sprinkle the 1 tbsp chopped fresh rosemary over the top for an aromatic finish. Let the bread cool in the pan for 10 minutes before transferring to a wire rack. This resting period allows the layers to set and prevents the prosciutto from sliding out when you slice. Serve warm for the best texture and flavor experience.
