Spaghetti Carbonara with Leeks and Pancetta

Ingredients

• 8 ounces uncooked spaghetti
• 1/2 cup (2 ounces) finely grated Parmigiano-Reggiano cheese
• 1/4 teaspoon black pepper
• 1/8 teaspoon salt
• 1 large egg
• 1 large egg white
• 1/2 cup chopped pancetta (about 2 ounces)
• 2 cups thinly sliced leek (about 2 large)
• 2 garlic cloves, minced
• 2 tablespoons chopped fresh flat-leaf parsley

Preparation

Cook pasta according to the package directions, omitting salt and fat. Drain, reserving 1/4 cup cooking liquid.

Combine cheese, pepper, salt, egg, and egg white in a small bowl, stirring with a whisk. Gradually add the reserved 1/4 cup cooking liquid to egg mixture, stirring constantly with a whisk.

Cook pancetta in a large nonstick skillet over medium-high heat until crisp. Remove pancetta from pan, reserving drippings in pan; set pancetta aside. Add leek to drippings in pan, and sauté 4 minutes. Add garlic to pan; sauté for 1 minute. Add pasta, cheese mixture, and pancetta to pan; reduce heat, and cook 1 minute, tossing well to coat. Cook 1 minute. Sprinkle with parsley; serve immediately.
