Recently made a batch of Barley and Mushroom Casserole. I make it generally about once a year and use it as a side dish. Each batch makes about 4-6 servings depending on how generous you're ladle is at the time.
6 tablespoons butter 1/2 tablespoon dried basil
2 cloves garlic, peeled and minced 3 cups chicken stock
2 yellow onions, peeled and minced 1/4 cup chopped parsley
1 pound mushrooms, thinly sliced 1 cup pearl barley
Preheat the oven to 375 F. While that heats, melt the butter in a 2-quart stove-top covered casserole. Add the garlic and onion and sauté over moderately low heat until the onion is translucent, about 5 minutes.
Add the mushrooms and sauté over moderate heat until the mushrooms are golden, about 5 minutes.
Add the barley and basil to the mushroom mixture, and toss lightly, the pour in the chicken stock and season to taste with salt and pepper. Slowly bring the casserole to a boil, them remove it from the heat. Cover and bake in the oven until the barley is tender, about 45 to 50 minutes. I recommend putting a pan on the lower rack beneath it just in case it boils up.
Before serving, add the chopped parsley and toss gently. Serve piping hot. Also quite tasty when reheated.
For myself, and my garlic addiction, I use more like 6-8 cloves. Because of what's available around here, I use white button mushrooms (they're grown relatively locally and so are fairly inexpensive for me to use).
Goes great with pork chops or chicken. Definitely a dish that "sticks to the ribs" as they say.
