Mushroom Barley Soup with Mini Meatballs

My little sister loves mushrooms and I realized in a recent conversation that I never post recipes with mushrooms on the blog. The reason for this is that I am not as crazy for these earthy fungi as my sister is but this hearty soup looks like a culinary delight. The meatballs are an easy mixture of sirloin, egg, cheese and breadcrumbs and the soup as whole comes together with ease so you can whip this up during the week no problem.

Mushroom Barley Soup with Mini Meatballs

1. 4 cups beef stock or low-sodium broth
2. 1 cup water
3. 1/2 cup pearled barley
4. 1 large thyme sprig
5. Salt and freshly ground pepper
6. 2 tablespoons extra-virgin olive oil
7. 1 pound mixed wild and cultivated mushrooms, stemmed and thinly sliced (or 3/4-pound presliced mushrooms)
8. 1 large shallot, finely chopped
9. 1/2 pound ground sirloin
10. 1 large egg
11. 2 tablespoons dry bread crumbs
12. 2 tablespoons freshly grated Parmigiano-Reggiano
13. 2 tablespoons chopped flat-leaf parsley
14. Sour cream, for serving (optional)

Directions

1. In a large saucepan, combine the stock, water, barley and thyme. Season with salt and pepper and bring to a boil. Cover and cook over low heat until the barley is nearly tender, about 18 minutes.
2. Meanwhile, in a large nonstick skillet, heat the oil. Add the mushrooms and shallot, season with salt and pepper and cook over high heat until tender and browned, about 8 minutes.
3. In a medium bowl, combine the sirloin, egg, bread crumbs, cheese, 1/2 teaspoon of salt and 1/4 teaspoon of pepper. Knead the mixture until blended, then roll it into sixteen 1-inch balls.
4. Add the meatballs and mushrooms to the soup and simmer over moderate heat until the meatballs are cooked through and the barley is tender, about 8 minutes. Discard the thyme. Stir the parsley into the soup and serve in bowls with sour cream.
