Walnuts are rich in omega-3s, which help reduce inflammation and increase good cholesterol. According to many nutritionists and doctors, walnuts help with depression and reduce risk of Parkinson’s and Alzheimer’s diseases. Walnuts are also loaded with fiber, manganese, vitamin E, protein, and minerals. Whenever a recipe calls for nuts, choose walnuts or at least part walnuts for your health. (Unless of course you are allergic to them!)
This walnut and breadcrumb crust adds a crunchy rich flavor to a comforting creamy potato and celeriac gratin. It can be baked ahead of time and reheated before serving.
Chef Maria Loi, author of “The Greek Diet” and chef of Loi Estiatorio, New York, makes an amazing walnut-olive spread that tastes great on everything from crudité and bread, to slathering it on a piece of fish just before grilling or broiling.
A chopped salad of excellent quality Parmesan-Reggiano, walnuts, and watercress with Belgian endive works as the perfect first course or as a unique hors d’oeuvres. Bon appétit!
Walnut Crusted Celeriac And Potato GratinAdapted from Chef Anne Kearney, New Orleans, LA
(Serves 4)1/2 cup half and half
2 large Idaho potatoes, peeled, thinly sliced
Sea salt and freshly ground black pepper to taste
1/2 cup freshly grated Parmesan cheese
1 large celeriac (celery-root) (1 to 1 1/2 pounds) peeled, thinly sliced
3/4 cup chopped toasted walnuts
1/4 cup dry breadcrumbs
Generous tablespoon extra virgin olive oilTo prepare:Line a 2-quart baking dish with parchment paper. Drizzle a thin layer of half and half over the paper.
Meanwhile, with a benriner or mandoline, thinly slice the potatoes, working quickly to prevent discoloration.
Line the bottom of the dish with a thin layer of potatoes, sprinkle salt, pepper, and cheese on top and a few drops of half and half. Repeat until you have four thin layers of seasoned potatoes.
Next, thinly slice the celeriac on the mandoline and make four similar layers each seasoned with salt, pepper, half and half, and cheese. Repeat the layering process until you have no more potatoes or celeriac.
In a small bowl, combine the walnuts and breadcrumbs together with oil and press the mixture evenly over the gratin.
Cover the dish with aluminum foil and bake for one hour or until the potatoes are tender to the point of a fork.
Remove the foil and brown the top until golden, about 15 to 20 minutes.
Let rest for 10 minutes before cutting and serving the gratin.
