This vibrant orecchiette with buttermilk, peas, and pistachios is a wonderful celebration of seasonal flavours. The unique combination of tangy buttermilk and sweet leeks creates a silky, light sauce that perfectly coats the ear-shaped pasta. With the addition of fresh mint and a hint of chilli warmth, this dish offers a sophisticated balance of textures, from the tender peas to the crunch of toasted pistachios.
As a nutritious vegetarian main course, this recipe is ideal for a quick midweek dinner or a relaxed weekend lunch with friends. The use of buttermilk keeps the dish feeling fresh rather than heavy, while the lemon juice provides a bright finish. Serve it with a simple green salad for a complete, wholesome meal that feels both comforting and elegant.

How to make Orecchiette with Buttermilk, Peas, and Pistachios
Back to contentsPreheat oven to 177°C. 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 tablespoons 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 90g 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.
