parsnip and sweet potato au gratin!

So a couple weeks ago, I found a recipe online for a Gratin dish--> here. So I went to the farmer's market, and bought a whole load of parsnips, I got home all excited to make the Parsnip Gratin, looked online for the recipe, when I realized it was RUTABAGA gratin! I got all grumpy and was like "what the heck am I gonna do with all these parsnips???" The hubby told me to calm down, and I reluctantly decided to make the dish anyways.

I had lots of second thoughts as I was preparing the sauce and the parsnips, I believe I even canceled dinner once or twice. When it started baking, it started filling up the house with a rich cheesey smell... Then we ate it, it had great texture, and the cashew cream sauce was fantastic as a "gratin." We did agree that parsnips are a pretty strong flavor, and this gratin would be improved upon by adding other veggies. So I decided to improve upon the gratin last night. Here's what I did and, by the way, it came out great!

ingredients:

1 3/4 c. boiling water
1 c. raw cashews
1/2 c. tahini
2 T chickpea (light) miso
1 big parsnip
1 big sweet potato
1/2 small red onion
salt
pepper
thyme
nutmeg

-cover cashews with boiling water, let sit for 20-30 minutes.
-using immersion blender, blend cashews (with water), tahini and the miso. this should be super creamy and smooth
-prepare veggies! i used the food processor to make thin discs of the parsnip and sweet potato. i also chopped up the onion into lil pieces
-coat baking dish with oil.
-then layer your gratin. i started with one layer of parsnips, then a lil salt, pepper, thyme. then a layer of sweet potato and a lil onion, then more salt, pepper, thyme. then added about 1/3 the cashew cream sauce. then more veggies, spices, etc... until you've used up all the veggies, and topped with the last of the sauce
-cover the dish, and bake at 400 for 50 min. use a knife to check for tenderness. if the dish is almost done, top with garlic breadcrumbs and bake for 10 more min until golden.
