Walnut-Sage Potatoes Au Gratin

Recipe by Annacia
READY IN: 31mins




  • 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.
