Author Notes

I used to follow a typical potato gratin recipe for many years. Then one day, I was out of potatoes. Plus, I was following a more stricter all natural diet and lower carbohydrate diet and I had zucchini on hand. Since this inception of the recipe, I have tried many variations of the recipe. This particular recipe is a fantastic variation. Tomatoes or another vegetable could be substituted for the mushrooms if not preferred. —amrecipes

This was good but had a soupy quality to it. Lots of liquid. Maybe I did something wrong. I was expecting more solid. Still good but needed a slotted spoon to serve.
I’d try it again but maybe without the milk?
