Oh my gosh, this combination is pretty heady. If you want to keep it vegetarian, leave out the bacon and use vegetable broth, but I like to incorporate the meaty components.
Serves 8 to 10
One 2lb butternut squash, peeled, seeded and sliced 1 inch thick
2 tbsp olive oil, plus more for the pan
1/3 cup pine nuts
1 large onion, finely chopped
4 slices bacon, cooked and crumbled
1/2 tsp dried sage, crumbled or 1 tsp fresh sage, chopped
salt and freshly ground black pepper
6 cups vegetable or chicken broth (or half and half with 3 cups of water and 3 cups of stock)
2 cups coarse polenta
unsalted butter
5 oz smoked Gouda cheese, shredded or sharp cheddar cheese, shredded
1/3 cup grated Parmigiano-Reggiano
Preheat the oven to 375F
Arrange the squash on a large oiled baking sheet and roast for 30 minutes, until tender. Transfer the squash to a bowl and mash coarsely. (You should have about 1 1/2 cups)
While the squash is roasting, spread the pine nuts on a pie plate and toast in the oven for 4 minutes, until golden. Coarsely chop the nuts.
Meanwhile, in a large skillet, heat 2 tbsp olive oil. Add the onion and sage and season with salt and pepper. Cover and cook over moderate heat, stirring, until golden, about 25 minutes.Add a few tbsp of water if the onions start getting dry.
In a saucepan bring the 6 cups stock/water to a boil. Whisk in the polenta and 1 tsp salt. Cook over very low heat, stirring frequently, until tender, about 35 minutes.The polenta will get very thick and that is fine. Stir in 1 tbsp butter along with the mashed squash, pine nuts, bacon, onion, Gouda or cheddar cheese and half the Parmesan cheese.Pour the hot polenta into a large springform pan or a 2 quart braising dish sprayed with non stick spray.
Flatten the top of the polenta slightly without spreading it to the edges; refrigerate until firm for up to an hour.
Cut 1 tbsp of the remaining butter over the polenta and sprinkle with the remaining 2 tbsp parmesan cheese.
Bake in a 375F oven for 1 hour, until the top and sides are lightly browned and crisp.
Let stand for 20 minutes before cutting it into wedges
Serve with sauteed mushrooms, braised greens or tomato sauce.
