It looks like everyone answered your question, but here's how I make my steel cut oats. (which I either get out of the bins at the natural food store or also in the health food section at Kroger). Put 1 cup in a saucepan & turn on medium heat to toast. Stir a bit as the oats heat up (they start to have a wonderful toasted smell!) for a few minutes. Then add 3 cups of water (do NOT stir). Let them boil, then reduce heat so they're just lightly bubbling/ simmering. You can cover them a bit or just let them cook for about 20 min. Then stir & serve by 1/2 cup portions (1 cup will make 4 portions). Refrigerate the rest & just warm it up as you like! This is my dd's favorite breakfast! (and mine too!) I add a Tbsp. of ground flax, Tbsp. chopped walnuts, and a splash of light soymilk sometimes too. Or add some fruit, dried fruit, or anything else that sounds good. ;-)
You can cook steel cut oats in the microwave also, but I don't think they turn out nearly as well as on the stove. And old fashioned oats are yummy too!! I use old fashioned oatmeal to cook with a lot too- I add it to my banana bread, muffins, pancakes, etc. My kids don't mind. ;-)
