Squash Mustard Gruyère Gratin Recipes

WINTER SQUASH GRATIN

Steps:

• Preheat the oven to 425ºF. Cover a baking sheet with foil and brush lightly with olive oil. Cut the squash in half, scoop out the seeds and stringy membranes, brush the cut sides with olive oil and lay cut side down on the foil-covered baking sheet. Bake 40 minutes, or until soft enough to pierce easily with a knife. Remove from the heat and allow to cool, then peel and either mash with a fork, puree in a food processor fitted with the steel blade, or finely dice. You should have about 2 cups of pureed or finely diced squash.
• Turn the oven down to 375ºF and oil a 2-quart gratin or baking dish with olive oil. Heat the remaining oil over medium heat in a medium heavy skillet and add the onion. Cook, stirring, until tender, about 5 minutes. Add the garlic and cook, stirring, until fragrant, 30 seconds to a minute. Stir in the parsley and sage, and squash, and remove from the heat. Season to taste with salt and pepper.
• Beat the eggs in a large bowl and whisk in the milk. Add 1/2 teaspoon salt and freshly ground pepper to taste. Stir in the squash mixture and the Gruyère. Taste and adjust seasonings. Scrape into the prepared baking dish and sprinkle the Parmesan over the top.
• Bake 30 to 40 minutes, until lightly browned on the top and sizzling. Serve hot, warm, or room temperature.

MERRITT'S BUTTERNUT SQUASH GRATIN

Steps:

• Preheat oven to 350 degrees F (175 degrees C). Grease a 9x13 inch baking dish.
• Melt the butter in a large skillet over medium heat. Stir in the onions and garlic; cook until the onions soften and turn golden brown, about 10 minutes. Add the butternut squash and brown sugar. Continue cooking and stirring until the butternut squash begins to brown on the edges, but is still somewhat firm in the center, about 10 minutes more. Scrape the squash into the prepared baking dish, and pour in the chicken broth. Wrap tightly with aluminum foil.
• Bake in the preheated oven until the liquid has been absorbed and the squash is tender, 45 to 50 minutes. Toss together the Gruyere cheese, Cheddar cheese, bread crumbs, thyme, and rosemary in a bowl until evenly combined. Remove the foil from the baking dish, and sprinkle the squash evenly with the cheese mixture. Sprinkle the Parmesan cheese on top. Return to the oven, and bake uncovered for 15 minutes more until the topping is lightly crunchy and brown.

DELICATA SQUASH GRATIN

Steps:

• Preheat the oven to 350 degrees F (175 degrees C). Spray a medium casserole dish with cooking spray.
• Slice delicata squash lengthwise, remove seeds and pulp, and cut into 1/2-inch crescent-shaped slices. Place squash in the prepared pan and lightly season with salt and pepper.
• Melt butter in a 1-quart saucepan over medium heat. Stir in flour and cook, stirring constantly, for 2 minutes, being careful not to allow the paste to brown. Gradually stir in milk and bring to a boil. Stir and cook for about 3 minutes; remove from heat. Mix in Gruyere cheese and stir until melted. Season with cayenne pepper, salt, and pepper.
• Pour cheese sauce over the squash and bake in the preheated oven until the squash is fork-tender, 25 to 30 minutes. Garnish with snipped parsley.

SQUASH GRATIN

Steps:

• Preheat the oven to 400 degrees F. Melt 2 tablespoons butter in a large ovenproof skillet over medium-high heat. Add the onion and thyme and cook, stirring, until the onion softens, about 5 minutes.
• Meanwhile, combine the butternut and kabocha squash in a large microwave-safe bowl with 1 cup water. Cover with plastic wrap and microwave until the squash is just tender, about 5 minutes. Drain and add the squash to the skillet along with the garlic, mace, 1 teaspoon salt and a few grinds of pepper. Cook, stirring, about 3 minutes. Add the broth and cook until it is mostly absorbed, about 5 more minutes. Stir in the heavy cream and cook until slightly thickened, 2 minutes.
• Melt the remaining 1 tablespoon butter in the microwave and toss with the breadcrumbs, parmesan and parsley; season with salt and pepper. Sprinkle over the squash, then top with the gruyere. Transfer the skillet to the oven and bake until golden, about 30 minutes. Let rest 5 minutes before serving.
