I grew up near mushroom country – miles and miles of stinky soil from which emerged these funny looking plants. Botanically, we knew that they were fungi, but culinarily, they were considered vegetables. Therefore they were suspect to my child-self.

However, as I grew older and learned about different kinds of mushrooms, I began to appreciate them and their diversity.

Mushroom Barley Casserole Tips

Although a meatier mushroom works well in this mushroom barley casserole, if you haven’t tried a variety of mushrooms, this is also a good recipe to experiment a bit more. 

So, if you are lucky enough to live near a mushroom farm or good farmers market, you can talk with the experts directly to figure out what you might enjoy most.

Also, I added the zucchini to bring in some sweetness. Springtime and end of winter zucchini are so small I needed to use three. But, by the time you get to summer, you will probably only need one for this mushroom barley casserole.

  • Preheat the oven to 350°.
  • Heat a skillet over medium-high heat. Add barley and toast for 2 minutes, then remove.

  • If your skillet can be placed in the oven, add the stock and marjoram. If not, transfer the barley and vegetables into an oven-safe dish and add the stock and marjoram and give a good stir. The barley will sink to the bottom of the pan, which is fine.
  • Bake for about 1 hour, until the barley is tender. Let cool for about 5-10 minutes, then serve.
