Hasselback Potato Casserole

A twist on the Hasselback potato made in a casserole for a crowd.



  1. Pre-heat the oven to 400ยบ.
  2. Grease a standard loaf pan with olive oil and set aside.
  3. In one bowl, toss the sliced potatoes with enough olive oil to lightly coat. Do the same in a separate bowl with the onions. Season the potatoes generously with salt, pepper and rosemary.
  4. Arrange the potatoes in the prepared dish, adding enough so they stand upright. Insert onion slices between some of the potato slices. Sprinkle with a little more salt.
  5. Cover dish with foil and bake for 1 hour. Uncover and bake another 15 minutes or more until potatoes are tender.
  6. Serve hot or at room temperature.


Season liberally as potatoes will be bland without salt.
