Ingredients

• 12 ounces egg tagliatelle or fettuccine (preferably fresh)
• 2 tablespoons (1/4 stick) unsalted butter
• 2 ounces thinly sliced prosciutto, torn into 1" pieces
• Zest and juice of 1 orange
• 1/2 cup heavy whipping cream
• Freshly ground black pepper
• 1/4 cup finely grated Parmesan

Instructions

1. Bring a large pot of water to a boil. Season with salt; add pasta and cook, stirring occasionally, until 1 minute before al dente, about 2 minutes for fresh pasta, longer for dried. Drain, reserving 1/4 cup pasta water.
2. Meanwhile, melt butter in a large heavy nonstick skillet over medium-high heat. Add prosciutto; sauté until browned, about 3 minutes.
3. Add reserved pasta water, orange juice, half of zest, and cream; bring to a boil. Add pasta; cook, stirring, until sauce coats pasta and pasta is al dente, about 1 minute. Season with salt and pepper. Stir in cheese and divide among warm bowls.
