Step 1

In a 12-inch skillet over medium, melt the butter. Add the leeks and ½ teaspoon salt, then cover and cook, stirring occasionally, until softened and tender, about 10 minutes. Add the wine and cook, uncovered and stirring occasionally, until most of the liquid has evaporated, 3 to 4 minutes.

Step 2

Stir in the barley, followed by the broth and 1 teaspoon pepper. Bring to a simmer over medium-high, then cover, reduce to medium and simmer, stirring occasionally, until the mixture is thick and creamy and the grains are tender, 40 to 45 minutes. If the consistency is thick and dryish before the barley is done, stir in ¼ cup water and cook, adding more water as needed, until the grains are tender.

Step 3

Stir in the asparagus and cook, uncovered and stirring occasionally, until the asparagus is tender-crisp, about 5 minutes. Off heat, stir in the crème fraîche, lemon zest and juice, and the dill. Taste and season with salt and pepper. Serve with additional crème fraîche on the side.
