This vibrant herby barley salad with butter-basted mushrooms is a masterclass in contrasting textures and deep, savoury flavours.

Ingredients for Herby Barley Salad With Butter-Basted Mushrooms

  • 150g hulled, hull-less, or pearl barley

  • Kosher salt

  • 2 shallots, thinly sliced into rings

  • 80ml vegetable oil

  • 2 tablespoons olive oil

  • 230g mushrooms (such as maitake, chanterelle, and/or oyster), torn or cut into large pieces

  • Freshly ground black pepper

  • 2 sprigs thyme

  • 1 clove garlic, crushed

  • 3 tablespoons unsalted butter

  • 1 cup chopped fresh coriander

  • 1 cup chopped fresh parsley

  • 2 tablespoons fresh lemon juice

  • 45g Parmesan, shaved, plus more for serving

Cook barley in a medium pot of boiling salted water until tender, 50–60 minutes for hulled or hull-less, 20–30 minutes for pearl. Drain; spread out on a baking sheet and let cool.

Meanwhile, cook shallots in vegetable oil in a small saucepan over medium-high heat, swirling pan occasionally to keep shallots from burning, until golden brown, 5–7 minutes. Using a slotted spoon, transfer shallots to paper towels to drain; season with salt. Let cool. Set shallot cooking oil aside.

Heat olive oil in a large skillet over medium-high until just beginning to smoke. Arrange mushrooms in skillet in a single layer and cook, undisturbed, until undersides are golden brown, about 3 minutes. Season mushrooms with salt and pepper, toss, and continue to cook, tossing often and reducing heat as needed to avoid scorching, until golden brown all over, about 5 minutes longer.

Reduce heat to medium and add thyme sprigs, garlic, and butter to skillet. Tip skillet toward you so butter pools at edge and use a spoon to baste mushrooms with foaming butter; cook until butter smells nutty. Using a slotted spoon, transfer mushrooms to a small bowl, leaving thyme and garlic behind.

Toss cooled barley, coriander, parsley, lemon juice, 45g Parmesan, and 2 tablespoons reserved shallot oil in a large bowl to combine; season with salt and pepper. Add mushrooms; toss again to combine.

Just before serving, top with fried shallots and more shaved Parmesan.

Barley can be cooked 1 day ahead. Let cool; store airtight and chill. Dish can be made 3 hours ahead; store tightly wrapped at room temperature.
