Pasta with creamy roasted squash, sage, and Parmigiano celebrates autumn's sweetest vegetable. This vegetarian mediterranean dish is fresh, family-friendly, and supports healthy eating goals.
Preheat the oven to 425°F. Cube butternut squash and toss with 2 tbsp olive oil and a pinch of salt; spread in a single layer on a baking sheet.
Roast squash for 25–30 minutes, flipping halfway, until golden brown and very tender.
Meanwhile, heat remaining 1 tbsp olive oil in a large skillet over medium heat. Add sliced onion and a pinch of salt; sauté 5–8 minutes, stirring occasionally, until soft and lightly golden.
Bring a large pot of salted water to a boil. Add pasta and cook according to package directions until al dente. Reserve 1 cup pasta water before draining.
Transfer roasted squash to the skillet with onions. Add half of the sage leaves (chopped) and mash squash gently, adding reserved pasta water as needed to create a creamy sauce over low heat.
Add cooked pasta to the skillet, tossing to coat well in the creamy squash sauce. Adjust consistency with more pasta water if needed.
Off the heat, fold in Parmigiano Reggiano. Taste and season with salt and black pepper. Top with remaining sage leaves (fried briefly in olive oil, optional) before serving.
