Who knew that steel-cut oatmeal could be treated like risotto? It would have never occurred to me until some friends suggested it. Food.com is so very comprehensive, should have known I would find a few versions of it here. Perfect comfort food on a chilly autumn day, warm, filling, and healthy. Mushrooms are optional. But if you are using them, wipe them clean with a paper towel. If they are washed, they act like a sponge, soaking up the water. I have only tried this with steel-cut oats, like McCann's or Bob's Red Mill.
