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



Roasted Cauliflower & Leek Gratin Recipe - (4.5/5) image

Provided by pikassob

Number Of Ingredients 15

ROASTED VEGETABLES:
2 small heads of cauliflower, about 3 pounds untrimmed
4 tablespoons olive oil
Kosher salt and pepper to taste
3 cloves garlic, minced
1 large leek
GRATIN:
1 1/2 tablespoons butter
1 1/2 tablespoons flour
2 cups low fat milk
1/2 cup generoud parmesan, gruyere or manchengo
Kosher salt and pepper, to taste
1 teaspoon whole grain Dijon mustard
1 to 2 ounce ham, cut into baton shapes
1/4 cup breadcrumbs

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.

Time 50m

Yield 4 to 6 servings

Number Of Ingredients 10

1 (3-pound) head cauliflower, cut into large florets
Kosher salt
4 tablespoons (1/2 stick) unsalted butter, divided
3 tablespoons all-purpose flour
2 cups hot milk
1/2 teaspoon freshly ground black pepper
1/4 teaspoon grated nutmeg
3/4 cup freshly grated Gruyere, divided
1/2 cup freshly grated Parmesan
1/4 cup fresh bread crumbs

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.

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.

CAULIFLOWER GRATIN WITH LEEKS AND WHITE CHEDDAR



Cauliflower Gratin With Leeks and White Cheddar image

A sort of cheater's gratin, this cauliflower cooked with leeks and cream doesn't require blanching or a béchamel, making it a low maintenance, deeply comforting side dish. To skirt the blanching, the cauliflower and cream is covered in foil to give the vegetables a chance to get tender without drying out. The foil then comes off so the top can brown and the cream can reduce, creating a thick, velvety sauce. If your heart desires a crunchier texture, add a scattering of bread crumbs tossed in olive oil and seasoned with salt and pepper when the aluminum foil comes off.

Categories     vegetables, side dish

Time 1h

Yield 4 to 6 servings

Number Of Ingredients 6

1 small-ish head cauliflower (about 2 pounds), green leaves removed
Olive oil, for drizzling
1 small leek, white and light green part only, very thinly sliced
Kosher salt and black pepper
¾ cup heavy cream
6 ounces sharp white Cheddar, grated (about 1 1/2 cups)

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.

CASHEW CAULIFLOWER AND LEEK GRATIN



Cashew Cauliflower and Leek Gratin image

My family loves this cauliflower gratin. It's different than scalloped potatoes and healthier with the added vegetables, and the cashew milk and cashew nuts add richness. Eliminate the white wine, if desired. -Nancy Heishman, Las Vegas, Nevada

ROASTED CAULIFLOWER GRATIN WITH TOMATOES AND GOAT CHEESE



Roasted Cauliflower Gratin With Tomatoes and Goat Cheese image

Roasting is one of my favorite ways to prepare cauliflower, and I have always loved preparations that pair the vegetable with coriander seeds. I use coriander seeds and cinnamon to season the tomato sauce that I toss with the roasted cauliflower and sautéed red onions, then add a couple of eggs beaten with goat cheese.

Provided by Martha Rose Shulman

Categories     dinner, lunch, main course, side dish

Time 1h20m

Yield Serves 4 to 6

Number Of Ingredients 12

1 medium-size head of cauliflower
Salt and freshly ground pepper to taste
3 tablespoons extra virgin olive oil
1 small or 1/2 large red onion, cut in half or quarters (if using a whole onion) lengthwise, then sliced thin across the grain
2 garlic cloves, minced
1 teaspoon fresh thyme leaves
1 (14 8/10-ounce) can chopped tomatoes in juice
1/8 teaspoon cinnamon
1/2 teaspoon coriander seeds, lightly toasted and coarsely ground
2 eggs
2 1/2 ounces soft goat cheese (about 1/2 cup plus 2 tablespoons)
2 to 3 teaspoon chopped chives

Steps:

  • Preheat oven to 450 degrees. Line a baking sheet with parchment or foil. Cut away the bottom of the cauliflower stem and trim off leaves. Cut cauliflower into 1/3 inch thick slices, letting the florets on the edges fall off. Toss all of it, including the bits that have fallen away, with 2 tablespoons of the olive oil, salt, and pepper. Place on baking sheet in an even layer.
  • Roast for 15 to 20 minutes, stirring and flipping over the big slices after 8 minutes, until the slices are tender when pierced with a paring knife and the small florets are nicely browned. Remove from oven and cut large slices into smaller pieces. You should have about 2 cups. Transfer to a large bowl. Turn oven down to 375 degrees.
  • Oil a 1-1/2 to 2-quart baking dish or gratin. Heat remaining oil over medium heat in a medium-size skillet or a wide saucepan and add onion. Cook, stirring, until tender, about 5 minutes. Add a generous pinch of salt and the garlic and thyme and continue to cook, stirring, until garlic is fragrant, 30 seconds to a minute. Add tomatoes, cinnamon, ground coriander seeds, and salt and pepper to taste and bring to a simmer. Cook, stirring often, over medium-low heat, for 10 to 15 minutes, until the tomatoes have cooked down and the sauce is fragrant. Taste and adjust seasoning. Add to bowl with the cauliflower and stir everything together. Scrape into prepared baking dish.
  • Set aside 2 tablespoons of the goat cheese. Beat eggs, then add the remaining cheese and beat together until smooth. Pour over cauliflower mixture, making sure to scrape out every last bit with a rubber spatula. Dot top with small pieces of the remaining goat cheese and sprinkle on chives.
  • Bake 30 minutes, until top is beginning to brown in spots. Remove from oven and allow to sit for 5 to 10 minutes before serving.

Tips:

  • Choose the right cauliflower. Look for a head of cauliflower that is firm and heavy, with no blemishes or bruises. The florets should be tightly packed and white or ivory in color.
  • Trim the cauliflower properly. Remove the leaves and tough outer layer of the cauliflower. Cut the cauliflower into florets, leaving about 1 inch of stem attached to each floret.
  • Roast the cauliflower before adding it to the gratin. This will help to bring out the cauliflower's flavor and give it a slightly caramelized texture.
  • Use a good quality cheese. The type of cheese you use will greatly affect the flavor of the gratin. Use a cheese that melts well, such as Gruyère, Emmental, or Parmesan.
  • Don't overcook the gratin. The gratin should be cooked until the cheese is melted and bubbly and the cauliflower is tender but still slightly firm.

Conclusion:

Roasted cauliflower leek gratin is a delicious and elegant dish that is perfect for a special occasion or a weeknight meal. It is easy to make and can be tailored to your own taste preferences. With its creamy cheese sauce, roasted cauliflower, and crispy leek topping, this gratin is sure to be a hit with everyone who tries it.
