Ingredients
3 large egg yolks
1 cup heavy cream
2 ounces Parmigiano-Reggiano, finely grated (1 1/4 cups), plus more for serving
1 teaspoon finely grated lemon zest, plus more for serving (optional), and 1 tablespoon fresh juice
Kosher salt and freshly ground pepper
12 ounces linguine
1 pound asparagus, trimmed and cut on the diagonal into 1-inch pieces (about 2 cups)
Preparation
In a bowl, whisk together egg yolks, cream, cheese, lemon zest, 1/2 teaspoon salt, and 1/8 teaspoon pepper to combine.
In a large pot of boiling salted water, cook pasta 2 minutes less than per package instructions. Add asparagus; cook until bright green and tender, about 2 minutes more. Reserve 1/2 cup pasta water; drain.
Return pasta and asparagus to pot along with egg mixture. Toss until well combined, adding a few tablespoons of pasta water at a time until sauce coats pasta. Add lemon juice; season to taste. Serve immediately, with more cheese, pepper, and lemon zest.
