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.

CAULIFLOWER GRATIN WITH LEEKS AND WHITE CHEDDAR

Steps:

• Heat oven to 425 degrees. Slice cauliflower head lengthwise into 1/2-inch thick slices, including the core and leaves. (Some smaller bits will fall away: That's fine. You'll use them as well.)
• Drizzle some olive oil onto the bottom of a 2-quart baking dish. (An oval, square or rectangular dish will all work.) Layer about a third of the cauliflower along the bottom, and about a third of the leeks. Season with salt and pepper, and repeat until all of the cauliflower and leeks are used. (Don't worry about perfectly layering them.) Season with salt and pepper and drizzle cream over. Scatter cheese on top, and season again with salt and pepper. Lightly cover with foil and place in the oven.
• Bake until cauliflower is nearly tender, 10 to 15 minutes. Remove foil and continue to bake until cream has thickened and reduced nearly completely and the top is golden brown and crisp, 35 to 40 minutes. Remove from oven and let cool slightly before eating.

CAULIFLOWER GRATIN

Steps:

• Preheat the oven to 375 degrees F.
• Cook the cauliflower florets in a large pot of boiling salted water for 5 to 6 minutes, until tender but still firm. Drain.
• Meanwhile, melt 2 tablespoons of the butter in a medium saucepan over low heat. Add the flour, stirring constantly with a wooden spoon for 2 minutes. Pour the hot milk into the butter-flour mixture and stir until it comes to a boil. Boil, whisking constantly, for 1 minute, or until thickened. Off the heat, add 1 teaspoon of salt, the pepper, nutmeg, 1/2 cup of the Gruyere, and the Parmesan.
• Pour 1/3 of the sauce on the bottom of an 8 by 11 by 2-inch baking dish. Place the drained cauliflower on top and then spread the rest of the sauce evenly on top. Combine the bread crumbs with the remaining 1/4 cup of Gruyere and sprinkle on top. Melt the remaining 2 tablespoons of butter and drizzle over the gratin. Sprinkle with salt and pepper. Bake for 25 to 30 minutes, until the top is browned. Serve hot or at room temperature.

CHEESY CELERIAC, LEEK & ROSEMARY GRATIN

Steps:

• Heat the butter in a saucepan. Add the leeks, rosemary and bay leaf, then cover and cook very gently over a medium-low heat for 15-20 mins until the leeks are soft. Pour over the milk and almost all of the cream, then season and bring to the boil. Remove from the heat and leave to cool a little, then scoop out the bay leaf.
• Pour a little of the leek mixture into an ovenproof gratin dish. Arrange a layer of celeriac in the dish, then season. Spoon over some more of the leek mixture and scatter with a little cheese. Repeat the process, alternating between layers of the leek mixture, cheese and celeriac slices, then finish with a drizzle of cream and the last of the cheese. Can be prepared up to a day ahead and kept in the fridge.
• Heat oven to 180C/160C fan/gas 4. Bake the gratin for 1 hr-1 hr 15 mins until the top is golden and the celeriac is tender when poked with a knife. If the gratin is browning a little too much, cover the dish in foil. Can be chilled, then reheated in a microwave or oven on a low heat with a drizzle more cream.
