Orecchiette with Buttermilk, Peas, and Pistachios

• portions: 4 servings

Ingrédients

¼ cup pistachios

12 oz. orecchiette

Kosher salt

12 oz. peas (such as shelled fresh or frozen English and/or halved sugar snap)

3 Tbsp. unsalted butter

2 Tbsp. extra-virgin olive oil, plus more for drizzling

2 medium leeks, white and pale green parts only, cut in half lengthwise, thinly sliced

3 garlic cloves, thinly sliced

½ tsp. crushed red pepper flakes

1 small bunch mint, divided

¾ cup buttermilk

3 oz. Parmesan, finely grated, plus more for serving

Freshly ground black pepper

2 Tbsp. fresh lemon juice

Instructions

Preheat oven to 350°. Toast pistachios on a rimmed baking sheet, tossing once, until golden brown, 5–8 minutes. Let cool, then coarsely crush with a measuring cup or glass.

Cook pasta in a large pot of boiling salted water 6 minutes, then add peas and cook until pasta is al dente, about 2 minutes more.

Meanwhile, heat butter and 2 Tbsp. oil in a medium heavy pot over medium. Cook leeks, garlic, red pepper flakes, and 3 mint sprigs, stirring occasionally, until leeks are soft but not browned, 6–8 minutes; season with salt. Add buttermilk; bring to a simmer. Pluck out mint; discard.

Using a slotted spoon, transfer pasta and peas to leek mixture. Add 3 oz. Parmesan; cook, stirring vigorously and adding a little pasta water if needed, until sauce is creamy and coats pasta, about 1 minute. Season with salt and pepper. Remove from heat; add lemon juice. Pull leaves from remaining mint sprigs, tear into pasta, and toss. Divide pasta among bowls. Top with pistachios and Parmesan; drizzle with oil.
