Best 8 Roasted Cauliflower Leek Gratin Recipes

ROASTED CAULIFLOWER & LEEK GRATIN RECIPE - (4.5/5)

Steps:

• ROASTED VEGETABLES: Cut cauliflower into florets that are 1 1/2 inches wide. In a large bowl, toss the florets with 3 tablespoons olive oil. Season with salt and pepper, and spread out on a large rimmed baking sheet. Roast until tender with just a bit of bite and browned. 35-40 minutes stirring occasionally. Stir in the garlic after 20minutes. Cut leeks into 1-inch pieces and toss with remaining oil and salt. Spread out on another rimmed baking sheet and roast until crispy in some parts and soft throughout. About 15 minutes. You can do this ahead of time (hours in advance). GRATIN SAUCE: Melt butter over medium low heat. Whisk in flour and cook. Stir constantly for 3-5 minutes, make sure that it doesn't brown. Whisk in the milk until smooth. Bring to a simmer. Maintain the heat so that it is bubbling gently, stir often until the sauce thickens and the flour cooks. Add 1/3 of parmesan and stir until just melted. Remove from heat and season well with salt and pepper. Stir in mustard. When the vegetables are done, reduce the vegetable temperature to 350°F. Toss the vegetables with the ham and add to a pan. Pour sauce evenly over vegetables. Combine the breadcrumbs with the remaining cheese and sprinkle over the top. Roasting the leeks and cauliflower (which you can do well ahead) brings out deeper flavor and a crisp-around-the edges texture. Serve as a dish with roasted meat or as a main course with salad and bread. If you don't feel like making the white sauce, gently warm 1 1/2 cups in a saucepan until it bubbles around the edges then stir in the cheese and season with salt and pepper. Pour it over the vegetables.
