Ingredients

•Fine sea salt

• 1/2 pound asparagus, trimmed

• 1 large shallot, finely chopped

• 2 tablespoons unsalted butter

• 2/3 cup heavy cream

• 14 ounces fresh tagliatelle, or dried tagliatelle

• 1/2 cup freshly grated Grana Padano or Parmigiano-Reggiano cheese

• 1/4 cup finely chopped flat-leaf parsley

Preparation

  1. Bring a large pot of salted water to a boil. Meanwhile, cut 1½ inches of asparagus tips from stalks. Steam tips for 3 minutes, then cut in half lengthwise. Cut stalks crosswise into ¼-inch rounds.

  2. In a medium saucepan, combine asparagus rounds, shallot and butter; cook over medium heat until butter is melted, then add 1/2 cup water, bring to a boil and cook for 3 minutes.

  3. Add cream, bring to a simmer and cook for 5 minutes. Season with ¼ teaspoon salt. Transfer pan contents to a blender and purée until smooth.

  4. Add pasta to the boiling water and cook until al dente (about 3 minutes for fresh pasta). Reserving ¼ cup pasta cooking liquid, drain pasta and transfer to a large bowl.

  5. Pour purée into a skillet; bring to a boil. Add asparagus tips, cheese and parsley; return to a boil, then add to bowl with pasta and toss to combine. Adjust seasoning and moisten with a little pasta cooking liquid, if desired. Serve immediately.
