In this dish, mushrooms, sage, and walnuts turn ordinary spaghetti into the perfect fall meal. The mix is filling, flavorful, and a welcome diversion from traditional sauce.

| 3/4 lb dried spaghetti | Kosher salt and freshly ground black pepper | |
| 3 Tbs extra-virgin olive oil | 2/3 cup loosely packed fresh sage leaves | |
| 1/2 cup unsalted butter | 1/3 cup toasted walnuts, coarsely chopped | |
| 3 large portabella mushrooms caps, gills scraped out and discarded, caps thinly sliced and cut into 2-inch pieces | 1/2 cup freshly grated Parmigiano-Reggiano |
Bring a large pot of salted water to a boil. Add the spaghetti and cook until it's tender but still firm to the tooth, about 9 minutes. Reserve 1 cup of the pasta cooking water and then drain the pasta and set aside.
Meanwhile, heat the olive oil and 2 Tbs. of the butter in a 12-inch skillet over medium-high heat until the butter is melted. Add the mushrooms, season with salt and pepper, and cook, stirring occasionally, until they're brown and tender, 4 to 5 minutes. Transfer the mushrooms to a bowl and set aside.
In the same sauté pan, melt the remaining 6 Tbs. butter over medium heat. Add the sage leaves, and cook, stirring occasionally, until they darken and crisp and the flecks of milk solids in the butter are golden brown, 3 to 5 minutes. Return the mushrooms to the pan and pile in the walnuts, the cooked pasta, and the 1/2 cup of the pasta water. Toss the pasta continuously with tongs to coat well, adding more water as needed so the pasta is moist, 1 to 2 minutes. (If your skillet isn't big enough, you can toss everything together in the pasta pot.) Season with salt and pepper, mound into bowls, and sprinkle generously with the Parmigiano. Serve immediately.
