Potato & leek gratin recipe
This Low-Carb “Potato” Leek Soup is a Paleo, low-carb, and dairy-free comfort food. No one will know this soup is made with cauliflower and not potatoes. This recipe was originally released on February 11, 2016. In fact, it was one of our very first recipes.
Pour the cream over the leeks and potatoes and top with the Gruyère. Cover with aluminum foil and transfer to the oven. Bake for 40 minutes, uncover and bake until the cheese is bubbling and golden, 15 to 20 minutes longer. Let cool slightly before serving.
Use a sharp knife to slice the leek in half, lengthwise, to expose the center. Flip each half over, cut-side down and slice them crosswise into thin 1/2-inch slices. Place the sliced leeks in a colander or salad spinner, rinse and drain well. Melt the butter in a 10-inch skillet over medium heat.
