Ingredients

  • 1 1/2 cups grapeseed or other neutral oil, more as needed
  • 1 large yellow onion, halved, peeled, and thinly sliced lengthwise
  • Kosher salt and freshly ground black pepper
  • 1 1/2 pounds russet potatoes (about 2 large)
  • 1 1/2 pounds butternut squash (about 1/2 medium)
  • 4 large eggs
  • 1 cup matzo meal
  • 1/3 cup finely chopped fresh parsley
  • 1/4 cup finely chopped fresh sage
  • 1 tablespoon chopped fresh marjoram

Method

  • Position racks in the top and bottom thirds of the oven and heat to 350F.
  • Heat 2 tablespoons of the oil in a medium skillet over medium-high heat.
  • When hot, add the onion and sprinkle with 1/2 teaspoon salt and a few grinds of black pepper.
  • Cook, stirring frequently, until the onions are golden all over and very soft, about 10 minutes.
  • Remove from the heat and set aside to cool.
  • Peel and grate the potatoes and butternut squash.
  • Put in a large bowl, along with the onions, eggs, matzo meal, parsley, sage, marjoram, 1 tablespoon salt, and 1 teaspoon pepper.
  • Toss gently to combine thoroughly.
  • Heat 3 tablespoons of the oil in a large skillet over medium-high heat.
  • When the pan is hot, use a 1/3-cup dry measure to scoop a mound of the mixture into the pan.
  • With a fork, spread and flatten the mixture to a 4-inch disk.
  • Repeat 3 more times.
  • When the first side is golden brown (about 2 minutes), carefully flip the latkes over and brown the other sides, about 2 minutes more.
  • Transfer the latkes to a rimmed baking sheet and continue to scoop and brown the remaining latke mixture in batches, adding another few tablespoons of oil before each new batch.
  • Arrange the latkes in a single layer on the baking sheet; youll probably need at least 2 sheets to accomplish this.
  • When all the latkes have been shaped and browned, transfer the baking sheets to the oven and bake until the latkes are cooked through, about 15 minutes.
  • Serve hot.
