Step 1

Combine the parsley, breadcrumbs, and orange zest in a small bowl. Set aside.

Step 2

Add 2 quarts of water, the salt, and linguine to a large saute pan. Cover and bring to a boil over medium-high heat. Reduce the heat to low and cook for 4 minutes or until the pasta is al dente.

Step 3

Meanwhile, cook the sausage in a 12-inch cast-iron skillet over medium-high heat until brown. Add the green onion and cook until fragrant.

Step 4

While the pasta and sausage are cooking, whisk together the eggs, cheese, and pepper.

Step 5

Drain the pasta, reserving 1/4 cup of the starchy water. Add the pasta to the sausage, tossing the pasta to coat in the fat.

Step 6

Remove from the heat, add the egg mixture, and thin as needed with the reserved pasta water.

Step 7

Serve immediately with a generous sprinkle of the parsley mixture.
