Potato-Tomato Gratin

Thinly sliced potatoes layered with tomatoes and a bit of (vegan) cheese offer an Italian twist to scalloped potatoes.

Yield: 4-6 servings

Time: 90 minutes


  • 9×13 baking dish
  • mandoline or very sharp knife
  • large bowl
  • small bowl


  • ΒΌ c olive oil, divided
  • 1 T fresh rosemary, minced
  • 1 t salt
  • pepper
  • 3 large potatoes (about 2 pounds), scrubbed
  • 6 oz melty mozzarella or other vegan mozz
  • 6 medium plum or roma tomatoes, seeded and chopped.


Oil the the baking dish and set aside.

Combine the rest of the oil with rosemary, salt, and pepper in the small bowl and set aside.

Slice the potatoes as thinly as possible (1/8 inch at most) and transfer to large bowl. Carefully toss with the rosemary oil to coat evenly.

Preheat oven to 400.

Arrange a third of the potatoes in the baking dish, overlapping slightly. Cover with half the mozz and then half the tomatoes. Add another third of the potatoes, then the rest of the mozz and tomatoes. Top with the rest of the potatoes.

Bake about one hour, until golden brown on top. Let cool for a few minutes before slicing and serving.
