Butternut Squash Lasagne with Goat Cheese

My friend Joan from Minneapolis and I agree on many things…two of them are that butternut squash and goat cheese belong together! This delightful variation on the lasagne theme came from her (and her favorite food site, Fine Cooking), just in time for the autumn harvest. And since we have about 20 packs of frozen chevre for our winter dining, I just defrosted one this weekend for the perfect entree!

Ingredients

1 large butternut squash (about 3 lb.), halved lengthwise and seeded
4 medium cloves garlic, unpeeled
2 sprigs fresh thyme plus 2 tsp. chopped leaves
2 tsp. extra-virgin olive oil + 1 tablespoon for mushroom sauteing
Kosher salt
Freshly ground black pepper
6 Tablespoons unsalted butter
2 sprigs fresh sage plus 1 tsp. chopped leaves
1-1/8 oz. (1/4 cup) all-purpose flour
3 cups whole milk
1-1/4 cups crumbled fresh goat cheese (8 oz.)
1 cup finely grated Pecorino Romano (2 oz.)
1/4 tsp. freshly grated nutmeg
2 cups of chunky marinara sauce
12 ounces of sliced, sauteed mushrooms
1/4 cup coarse dry breadcrumbs or panko
1 recipe Fresh Pasta for Lasagne

Roast the squash and garlic
Position a rack in the center of the oven and heat the oven to 425°F.

Put the squash cut side up on a large, heavy-duty rimmed baking sheet. Put 1 garlic clove and 1 sprig of thyme in each cavity. Drizzle each half with 1 tsp. of the oil and then season each with 1/4 tsp. salt and a few grinds of pepper. Roast until the squash is browned in spots and very tender when pierced with a skewer, 45 to 50 minutes. Remove from the oven and let cool completely.

Discard the thyme sprigs. Peel the garlic and put in a large bowl. Scoop the squash flesh from the skins and add it to the garlic. Mash with a fork until smooth. Season to taste with salt and pepper.

Reduce the oven temperature to 350°F.

Make a goat cheese and sage sauce
Melt 4 Tbs. of the butter in a 3-quart saucepan over medium heat. Add the sage sprigs and cook until the butter is fragrant, 2 to 3 minutes. Discard the sage. Add the flour and whisk until smooth and golden, about 2 minutes. Gradually whisk in the milk and cook, whisking occasionally, until thickened enough to coat the back of a spoon, about 15 minutes. Stir in the goat cheese, 1/2 cup of the pecorino, the nutmeg, 1 tsp. salt, and a few grinds of pepper. Season to taste with more salt and pepper. Set aside 1-1/2 cups of the sauce and mix the rest with the mashed squash.
Preparing Mushrooms
Clean 12 ounces of button or portobello mushrooms, slice them and saute them in 2 tablespoons of butter and 1 tablespoon of olive oil. Set them aside.
Season the breadcrumbs
Melt the remaining 1 Tbs. butter in a small skillet over medium heat. In a small bowl, mix the breadcrumbs, chopped sage, chopped thyme, a pinch of salt, and few grinds of pepper. Add the melted butter and mix well.
Assemble and bake the lasagne
Spread 1/2 cup of the reserved cheese sauce over the bottom of a 9x13x3-inch baking dish. Cover the sauce with a slightly overlapping layer of cooked noodles, cutting them as needed to fill any gaps. Spread 1 cup of the squash mixture evenly over the noodles. Add ladles of the tomato sauce, then a sprinkling of mushrooms and then add another layer of noodles and repeat the layers as instructed above, to make a total of 4 squash layers and 5 pasta layers. Spread the remaining 1 cup cheese sauce evenly over the top. Sprinkle with the breadcrumb mixture and the remaining 1/2 cup pecorino.

Cover the baking dish with foil and bake for 40 minutes. Remove the foil and bake until the top is browned and bubbly, 15 to 20 minutes. Cool for at least 10 minutes before serving.

Make Ahead Tips

You can make the roasted squash mixture up to 1 day ahead of assembling the lasagne.

You can assemble the lasagne up to 2 days ahead of baking it. Tightly wrap the baking dish in plastic and refrigerate it. Let the lasagne come to room temperature before baking it.

Thanks, Joan!
