Creamy Farro with Crispy Shiitakes

Adapted from Whole Living
~from Savoring Time in the Kitchen

3 tablespoons extra-virgin olive oil
1 shallot, minced
1 cup farro (I was able to find the Roland brand at my local store)
1/4 cup dry white wine
3 cups low-sodium chicken stock (I like Kitchen Basics brand)
Coarse salt
12 ounces wild mushrooms, such as shiitake or oyster, trimmed and cut into 1/2-inch slices (I used all Shiitake mushrooms)
Red-pepper flakes
1 bunch spinach (10 ounces), stemmed
1/4 cup grated Parmesan, plus more for serving

Heat a medium saucepan over medium heat.  When hot, add 1 tablespoon oil. Add shallot and cook, stirring occasionally, until tender, about 5 minutes. Add farro, stirring until toasted, about 1 minute. Add the wine and cook until reduced by half. Add chicken stock, bring to a boil, then reduce heat and simmer, stirring occasionally, until farro is tender and creamy, 35 to 40 minutes. Season with salt and cover to keep warm.

Meanwhile, heat the oven to 450 degrees. On a rimmed baking sheet, toss mushrooms with remaining 2 tablespoons oil and season with salt and red-pepper flakes. Roast, stirring once, until crisp and golden, 20 to 25 minutes.

Warm farro over medium heat and add spinach, stirring until wilted, about 1 minute. Stir in mushrooms and Parmesan. Pass additional Parmesan at the table.
