WALNUT-SAGE POTATOES AU GRATIN

Steps:

• Peel potatoes, if desired, and thinly slice - I used the thin slicing blade on the food processor - (should have 6 cups).
• Place slices in a colander.
• Rinse with cool water; set aside to drain.
• For sauce, in a medium saucepan on med to med-high heat (I have found walnut oil doesn't have a high heat tolerance)cook onion and garlic in walnut oil until tender but not brown.
• Stir in flour, salt, and pepper.
• Add milk all at once.
• Cook and stir over medium heat until thickened and bubbly. Remove from heat; stir in snipped sage.
• Grease a 2-quart round casserole (with glass cover).
• Layer half of the potatoes in casserole. Cover with half the sauce.
• Sprinkle with half the cheese.
• Repeat layering with the potatoes and sauce. (Cover and chill remaining cheese until needed.).
• Bake casserole, covered, in conventional oven at 350 degrees F for 40 minutes. Uncover; bake 25 minutes more or until potatoes are just tender.
• Sprinkle remaining cheese and nuts over top. Bake, uncovered, 5 minutes.
• Let stand 10 minutes.
• Top with sage leaves.
