This savory and sweet lasagna is as decadent, delicious and wintery as it sounds. It’s an excellent use of butternut squash (or any favorite winter squash) and it makes an elegant, memorable meal for any dinner party or holiday celebration.Feel free to add more Swiss chard to the sautéed filling for “greener” layers and add a bulb of fennel, thinly sliced, to elevate further with added sweetness and subtle anise flavor (highly recommended!). The fenugreek is optional, but it’s the secret ingredient that adds complexity and balances the sweetness of the squash with just a touch of bitterness. Try a simple salad of arugula, radicchio and chickpeas with balsamic vinaigrette to serve on the side.
Heaping 2½ cups coarsely shredded Italian fontina cheese (6½ ounces)
Heaping ¼ cup finely grated Parmesan cheese
Freshly ground black pepper
Instructions
Make the butternut squash filling
Heat the oven to 400°F with a rack in the middle position and line a sheet pan with parchment paper. Trim the ends of the butternut squash. Cut the squash in half crosswise through the middle to separate the bulbous bottom of the squash from the slender and solid neck. Next, cut the bulbous bottom in half lengthwise. Stand the neck of the squash upright on its widest cut surface and cut it in half lengthwise. Brush the squash lightly with the oil and roast flesh side down for 50 to 60 minutes, until the squash flesh is completely tender. Once cool enough to handle, scoop out the seeds and discard them. Now, use a spoon to separate the flesh from the skin. Place 3½ to 3¾ cups of the flesh in a food processor. Add the fenugreek (if using), nutmeg, salt, vinegar and maple syrup and blend on high until completely smooth. Set aside. (Note: At this point the squash purée will have a sharp vinegar-forward flavor that will mellow and add welcome acidity to the lasagna.)
Make the chard filling
Heat the oil in a large skillet over medium heat. Add the onion, fennel (if using), and chard stems and cook, stirring occasionally, until the onion is beginning to turn translucent and soften, 4 to 6 minutes. Add the garlic, ¼ teaspoon of salt and the pepper and cook, stirring occasionally, until the onion is lightly browning in places, about 3 minutes. Add the chard leaves, cooking down a little at a timeto fit the skillet, along with the remaining ¼ teaspoon of salt and a few twists of pepper. Once all of the chard is in the pan, cook, stirring frequently, until wilted and all of the liquid has evaporated, about 4 minutes. Set aside.
Make the cream sauce
In a medium bowl, whisk together the cottage cheese, cream, Parmesan, rosemary, salt, pepper, and nutmeg
