Potato Cake with Cheese and Bacon

A potato pancake, with cheese and bacon, with a slice missing, on crumpled parchment
This potato pancake with cheese and bacon, called a truffade in French, is simple to make. Potato slices are fried in lard or olive oil, and Cantal or Gruyere cheese and bacon bits are stirred in. To make a hearty meal of it the Auvergne way, serve it with meaty pork sausages.

  • 5 ounces lean bacon
  • 2 tablespoons lard or mild olive oil
  • 2 pounds baking potatoes peeled if desired and thinly sliced
  • Salt and freshly ground black pepper to taste
  • 8 ounces Cantal or Gruyère cheese diced or cut into thin, narrow strips


  • Trim any rind from the bacon. Cut the bacon into slices 3/8 inch thick. Stack the slices and cut them crosswise into short strips. In a 10-inch (25 cm) deep-sided skillet over medium heat, fry the lardons (this is just a fancy French word for bacon chunks) until they release their fatty goodness in the form of bacon drippings, 2 to 3 minutes. Do not let the bacon brown. Remove the bacon with a slotted spoon and place on a paper towel-lined plate.
  • Add the lard to the skillet, return to medium heat, and wait until it melts. Toss in the potatoes and sprinkle them with salt and pepper. (Be judicious with the salt as the bacon may make the potato pancake salty enough.) Reduce the heat to low, cover, and cook for 5 minutes. Stir in the lardons and continue to cook, uncovered, over low heat, tossing or stirring often, until the potatoes are tender and some of the potatoes are lightly browned, 20 to 25 minutes. Don't worry if some of the potatoes get crushed, as this will help hold the potato pancake together.
  • Stir in the cheese and season again with salt and pepper. Using the back of a spatula, press down on the potatoes to make them even in the skillet. Turn the heat to medium-high and let the potato pancake cook, without stirring, until the bottom is browned, 3 to 5 minutes, pressing on the cake occasionally with the back of the spatula to hold it together. When the potato cake, or truffade, is done, it should be brown around the edges and starting to pull from the sides of the pan.
  • Take the skillet off the heat, run a knife around the edge of the cake to loosen it, and then turn it out onto a warmed plate or platter or serve it straight from the skillet. Cut into wedges and serve hot.
