Potato gratin (or scalloped potatoes) make a classic side dish of roasted chicken or meat. But most recipes are made with cream, so they're a no-go menu addition for those who keep kosher. Enter coconut milk, which lends creaminess without dairy.

Choose thick canned coconut milk for this recipe, rather than the thinner refrigerated coconut beverages that are designated as cow's milk replacements. You'll get richer coconut flavor with full-fat coconut milk. When you open the can, give it a stir to incorporate the coconut cream with the coconut water, which tends to separate. 

This coconut curry potato gratin would be delicious with brisket or a simple roast chicken. Vegans can turn the hearty potatoes into a delicious weeknight meal by skipping the meat and adding a generous helping of roasted vegetables

What You'll Need

  • 2 pounds/1 k potatoes (Yukon Gold or others)
  • 2 tablespoons oil (neutral such as canola or sunflower)
  • 1/4 cup margarine
  • 2 large onions (peeled, trimmed, and thinly sliced)
  • 4 garlic cloves (peeled, smashed, and finely chopped)
  • 1 teaspoon curry powder
  • 1 1/2 cups coconut milk
  • Sea or kosher salt (to taste)
  • Freshly ground pepper (to taste)

How to Make It

  1. Heat the oven to 400 F/200 C.  Fill a large bowl about halfway with cold water. Grease a 2 1/2- to 3-quart casserole or similarly sized baking pan (a 7x11x2-inch or 9x9x2-inch baking pan would work).
  2. Peel the potatoes. Slice into rounds about 1/8-inch thick. (If desired, you can use a food processor fitted with a slicing blade.) Place the potatoes into the bowl of cold water, and set aside.
  3. In a large skillet set over medium-high heat, warm the oil and margarine. Add the onions and saute until they are soft and translucent​ about 5 minutes. Remove the onions from the pan with a slotted spoon or tongs, transfer to a dish, and set aside.
  1. Add the garlic and curry powder to the hot oil left in the pan, and saute for about 30 seconds, or just until fragrant. 
  2. Stir in the coconut milk, and bring to a simmer. Season to taste with the salt and pepper and remove from the heat.
  3. Drain the potatoes and pat dry. Place half of the onions in the prepared baking dish. Cover with half of the potatoes. Layer with the rest of the onions and top with the rest of the potatoes. Pour the coconut milk mixture evenly over the top of the potatoes.
  4. Cover the pan with foil and bake for 1hour. Remove the foil and bake for 15 to 30 minutes more, or until you can pierce the potato layers easily with a knife and the top of the gratin is nicely browned.
