This crispy potato and leek kugel is a wonderful vegetarian dish that offers a sophisticated twist on a traditional favourite. By combining smooth mashed potatoes with grated textures and sautéed leeks, the recipe achieves a beautiful internal consistency that contrasts perfectly with the golden, shingled potato topping. Fresh thyme and aromatic garlic provide a fragrant, savoury depth that elevates these humble ingredients into something truly special for any dinner table.
Ideal as a comforting side dish for Sunday lunch or as a substantial vegetarian main, this kugel is designed for sharing. Heating the oil in the baking tin before adding the mixture ensures a wonderfully crisp bottom crust, while a quick finish under the grill creates an irresistible crunch on top. It is best served warm, cut into generous squares, making it a reliable crowd-pleaser for family gatherings or festive celebrations.

Ingredients for Crispy Potato-Leek Kugel
9 medium russet potatoes (about 2.0kg), peeled
110ml vegetable oil, divided
3 medium leeks, white and pale-green parts only, thinly sliced crosswise
2 1/2 teaspoons kosher salt, divided, plus more
3/4 teaspoons freshly ground black pepper, divided
2 garlic cloves, finely chopped
1 small onion
4 large eggs, lightly beaten
1 tablespoon plus 1 teaspoon fresh thyme leaves, divided
An 8x8" baking pan
How to make Crispy Potato-Leek Kugel
Back to contentsPreheat oven to 375°. Cut 4 potatoes into 1" chunks and place in a medium pot. Cover with cold water by 1". Season water generously with salt, bring to a boil over medium-high heat, and cook until potatoes are tender, 10-12 minutes. Drain well, transfer to a large bowl, and mash with a potato masher; set aside.
Meanwhile, heat 2 tablespoons oil in a large skillet over medium until shimmering. Add leeks, 1/4 teaspoons salt, and 1/4 teaspoons pepper and cook, stirring frequently, until softened and golden, 5-8 minutes. Add garlic and cook until fragrant, 1-2 minutes more. Remove pan from heat and let cool slightly.
Grease bottom and sides of an 8x8" baking pan with 2 tablespoons oil. Place pan in oven for 10 minutes.
Meanwhile, grate 3 potatoes and onion using the large holes of a box grater or a food processor fit with a shredding blade. Wrap potatoes and onion in a clean dishtowel or several layers of paper towels and squeeze out as much liquid as you can; add to the bowl with the mashed potatoes. Stir in sautéed leeks and garlic, eggs, 2 tablespoons oil, 1 tablespoon thyme, 2 teaspoons salt, and 1/4 teaspoons pepper; mix until well combined.
Thinly slice remaining 2 potatoes and toss with remaining 1 tablespoon oil, 1 teaspoon thyme, 1/4 teaspoons salt, and 1/4 teaspoons pepper in a medium bowl; set aside.
Carefully remove preheated pan from oven and transfer potato-onion mixture to the pan (it should sizzle when it hits the hot oil). Smooth top with a spatula. Layer potato slices over the top in a shingled fashion. Bake until golden brown and cooked through, 60-75 minutes. Heat grill; grill kugel until crispy crust forms, 1-2 minutes, watching carefully so it does not burn. Let cool briefly, then cut into squares to serve.
