Ingredient Checklist


Instructions Checklist
  • Heat oil in a pot over medium-high. When it shimmers, add mushrooms and onion; season with salt and pepper. Cook, stirring occasionally, until tender and golden brown in places, 10 to 12 minutes. Add grains and cook, stirring a few times, until toasted and nutty, 2 to 3 minutes.

  • Add broth; bring to a boil, then reduce heat to medium-low and simmer until grains are just cooked, 12 to 15 minutes. Remove from heat. Stir in Pecorino and lemon juice; season with salt and pepper. Serve with watercress, a drizzle of oil, more cheese, and lemon wedges.

Cook's Notes

Look for packages of "super-grains" at the store in the rice and grains section; they will contain a blend of quinoa, millet, and buckwheat. Alternatively, any variety of quinoa will work fine for this recipe. A variety pack of wild mushrooms, such as shiitake, cremini, and oyster, will give this soup a deeper flavor, but a single variety will work, too.
