3/4 pound pappardelle or fettuccine
1 tablespoon olive oil
1/2 pound peeled and deveined medium shrimp (raw)
kosher salt and black pepper
2 small shallots, sliced
1/2 to 1 teaspoon crushed red pepper
1 large bunch asparagus (about 1 pound), trimmed and cut into 1 1/2-inch pieces
3 tablespoons unsalted butter, cut into pieces
1 teaspoon finely grated lemon zest, plus 2 tablespoons lemon juice

Cook the pasta according to the package directions. Reserve ¾ cup of the cooking water and drain the pasta.

Meanwhile, heat the oil in a large skillet over medium-high heat. Season the shrimp with ¼ teaspoon each salt and black pepper. Cook until browned on one side, 2 to 3 minutes.

Add the shallots and red pepper. Cook, tossing frequently, until the shallots are crisp-tender, 30 seconds to 1 minute.

Add the asparagus and cook, stirring occasionally, until crisp-tender, 3 to 4 minutes.

Add the pasta, butter, lemon zest, lemon juice, and ½ cup of the reserved cooking water to the shrimp and asparagus and toss to coat. (Add more cooking water as needed to loosen the sauce.)

Serve warm.
