Recipe for Savory Potato Walnut Cake. The name says it all - this is a savory, potato cake with walnuts - the perfect appetizer to serve hot or at room temperature.


  • 4-5 medium-sized red-skinned boiling potatoes or Yukon Gold potatoes (about 1 1/4 pounds)
  • 1 tablespoon olive oil
  • 1 medium yellow onion, sliced
  • 1 red bell peppers, halved, seeded and sliced
  • 2 cloves garlic, chopped
  • 3/4  cup  walnuts
  • 1 1/2 tablespoons chopped fresh thyme OR 1 1/2teaspoons dried thyme
  • salt and pepper to taste
  • 2 large egg whites, lightly beaten
  • 1 cup nonfat plain yogurt


  1. Place the potatoes in a steamer basket in a large pan over boiling water. Cover the pan and steam until the potatoes are just tender when pierced, 20-30 minutes, depending on size. Let the potatoes cool, then chop them coarsely. Transfer to a large bowl and set aside.
  2. Preheat the oven to 400ºF. Coat a 9-inch round cake pan with nonstick cooking spray, then line the bottom with a round of parchment paper, cut to fit. Coat the parchment lightly with nonstick cooking spray as well.
  3. Place a large nonstick skillet over medium-high heat. Add the olive oil, onion, pepper and garlic and cook, stirring occasionally, until the vegetables are tender and wilted, about 10 minutes. Add the walnuts along with 1 tablespoon fresh thyme or 1 teaspoon dried, and cook about 1 minute longer.
  4. Add to the bowl with the potatoes and stir to combine. Season with salt and pepper to taste. Add the egg whites and stir briskly with a fork until evenly mixed. Press and pat the mixture evenly in the prepared pan. Bake until the potato cake is dry on top and firm to the touch, 30-35 minutes. Remove from the oven and cool 10 minutes. Slide a table knife around the edge of the pan, then shake the pan to loosen the cake. Invert onto a serving plate, then lift off the pan and peel away the parchment paper.
  5. Meanwhile, stir the yogurt together with the remaining thyme. Cut the potato cake into 8 wedges and serve warm or at room temperature. Top each wedge with some of the yogurt sauce.
