- Yield: 8 Servings
Ingredients
3 tablespoons extra virgin olive oil, divided
1 cup pearl barley, picked through for debris, rinsed and drained
Zest and juice of 1 lemon
1 bay leaf
2 1/2 cups low sodium vegetable broth
4 cloves garlic, pressed or finely grated
1/8 teaspoon black pepper
8 ounces button mushrooms, wiped clean and halved
12 ounces green beans, washed, dried, trimmed and halved
1/4 cup walnuts, chopped
Pinch of kosher salt
2 tablespoons chopped basil about 6 large leaves
Instructions
1 Preheat the oven to 425ºF. Heat one tablespoon of oil in a medium saucepan over medium high heat. Add the barley and cook until toasted and fragrant, about 8 minutes, stirring occasionally. Add the lemon zest, bay leaf and vegetable stock and bring to a simmer. Cover and simmer on medium low until tender, about 30 minutes, stirring every 10 minutes, remove from the heat.
2 Line a rimmed baking sheet with parchment or a silicone baking mat. In a small bowl combine the remaining 2 tablespoons olive oil, garlic and pepper. If mushrooms vary in size, cut larger mushrooms into quarters. The more similar the size, the more evenly they will roast. Place mushrooms and green beans on the prepared baking sheet. Drizzle with the garlic oil, toss to coat and spread out in a single layer. Roast for 15 minutes, undisturbed. Add the walnuts and toss. Continue roasting for 5 minutes or until vegetables are tender and caramelized and walnuts are toasted.
3 Remove bay leaf from barley and toss with a fork. Transfer barley to a serving bowl or platter. Top with roasted vegetables and garnish with a squeeze of lemon juice, salt and chopped basil.
