Inspired by Osteria Francescana's innovative "Caesar Salad in Emilia," this recipe brings the essence of Modena to your home kitchen with familiar ingredients and refined flavors.
Preheat oven to 350°F (175°C). Lay prosciutto slices on a baking sheet and bake for 8-12 minutes, or until crisp. Let cool, then crumble.
In a medium bowl, toss sourdough crumbs with 2 tbsp olive oil, minced garlic, and red pepper flakes (if using). Spread on a baking sheet and bake alongside prosciutto for 5-7 minutes, until golden and crunchy. Combine cooled prosciutto crumbles and sourdough crumbs.
In a medium bowl, whisk together egg yolks, Dijon mustard, lemon juice, Worcestershire sauce, mashed anchovy fillets, and minced garlic until well combined.
Slowly drizzle in the 1/2 cup extra virgin olive oil while continuously whisking, until the dressing emulsifies and thickens.
Stir in the 1/4 cup grated Parmigiano Reggiano. If the dressing is too thick, whisk in 1-2 tbsp of water until desired consistency is reached. Season with salt and freshly ground black pepper to taste.
Tear or chop the Romaine lettuce into bite-sized pieces. In a large bowl, add the lettuce and drizzle with about half of the dressing. Toss gently to coat. Add more dressing as desired, ensuring not to overdress.
Divide the dressed lettuce among serving plates. Sprinkle generously with the crispy prosciutto and sourdough crumbs. Top with shaved Parmigiano Reggiano. Drizzle each salad with aged balsamic vinegar. Garnish with fresh chives or parsley, if using. Serve immediately.
