This Italian-style butternut squash pasta pairs tender pasta with roasted squash, butter, sage, and Parmesan in a sauce made silky with pasta water. Pasta with zucca appears in different regional and family versions in Italy; butternut squash is a convenient choice for this home-style take, not the only traditional squash used.
Ingredients
- 2 lb peeled, seeded butternut squash, cut into ¾-inch cubes (900 g)
- 1 tbsp extra-virgin olive oil (15 ml)
- ¾ tsp fine salt for the squash (4 g), plus more to taste
- ¼ tsp freshly ground black pepper (about 0.5 g)
- 12 oz dried short pasta, such as rigatoni, mezze rigatoni, or casarecce (340 g)
- 4 qt water for cooking the pasta (3.8 L)
- 1 tbsp fine salt for the pasta water (15 g; adjust if using a very fine or coarse salt)
- 3 tbsp unsalted butter (42 g)
- 8 fresh sage leaves, finely sliced (about 2 g)
- 2 garlic cloves, finely chopped (about 6 g)
- ½ cup low-sodium vegetable broth (120 ml)
- ⅛ tsp freshly grated nutmeg (about 0.25 g)
- ¾ cup finely grated Parmigiano-Reggiano, plus extra for serving (60 g)
- ½ cup pasta cooking water, reserved as needed (120 ml)
- ⅛ tsp red pepper flakes, optional (about 0.25 g)
Instructions
- Heat the oven and prepare the squash. Set a rack in the center of the oven and heat it to 425°F (220°C). If the squash is not already peeled, remove the peel with a sturdy vegetable peeler, halve it lengthwise, scoop out the seeds, and cut the flesh into evenly sized ¾-inch cubes. Toss the cubes on a rimmed baking sheet with the olive oil, ¾ teaspoon salt, and black pepper. Spread them out in one layer, leaving a little space between pieces so they roast rather than steam.
- Roast until tender and browned. Roast the squash for 25 to 30 minutes, turning the pieces once after about 15 minutes. It is ready when a knife slips into a cube easily and the edges have a few golden-brown spots. The exact time depends on the squash and how evenly it is cut. Remove the pan from the oven and set it nearby; keep the squash on the pan so the browned juices are not lost.
- Cook the pasta while the squash roasts. Bring the 4 quarts of water to a boil in a large pot, add the tablespoon of salt, and stir in the pasta. Cook it for the package’s suggested time until al dente, tasting a piece near the end rather than relying only on the clock. Before draining, scoop out at least ½ cup of the starchy cooking water. Drain the pasta, but do not rinse it; the starch on the surface helps the sauce cling.
- Make the sage and squash sauce. While the pasta cooks, melt the butter in a wide skillet over medium heat. Add the sliced sage and cook for about 1 minute, stirring, until fragrant but not dark. Add the chopped garlic and optional red pepper flakes and cook for 30 seconds. Pour in the vegetable broth, then add about two-thirds of the roasted squash and the nutmeg. Mash the squash in the skillet with a fork or potato masher until it forms a rough, thick sauce. A few small squash pieces are welcome; it does not need to be completely smooth.
- Bring the pasta and sauce together. Add the drained pasta to the skillet and toss over low heat for 1 to 2 minutes. Stir in ¼ cup (60 ml) of the reserved pasta water, adding another splash if the sauce looks stiff or gathers in clumps. The finished sauce should coat the pasta and look glossy, not watery. Fold in the remaining roasted squash and the grated Parmigiano-Reggiano. Taste before adding more salt, since both the pasta water and cheese contribute salt.
- Finish and serve promptly. Turn off the heat and toss once more. If the pasta has sat for a minute and thickened, loosen it with a tablespoon or two of reserved pasta water. Divide it among warm bowls and finish with extra Parmesan, a little black pepper, and a few thin sage leaves if you have them. Serve while the sauce is creamy and the roasted squash is still warm.
Tips
- Cut the squash evenly. Similar-sized cubes roast at roughly the same rate. Very small pieces can dry out before larger ones soften, while oversized chunks take longer and make the sauce harder to mash. If some pieces are done early, take them off the tray and let the rest roast a few minutes more.
- Keep pasta water before draining. It is easy to forget, so set a heatproof cup by the sink before you drain the pot. Add the water gradually: a little loosens the squash, butter, and cheese into a sauce, while too much can make the dish thin.
- Use a practical cheese substitute if needed. Grana Padano is a good Italian alternative to Parmigiano-Reggiano and gives a similarly savory, nutty finish. A firm vegetarian hard cheese can also work, though the flavor will differ; check its label if avoiding animal rennet.
- Do not brown the garlic or sage heavily. The butter should gently sizzle, not smoke. Burnt garlic can turn bitter and overpower the squash. If the skillet gets too hot, take it off the burner briefly before adding the broth.
Serving Suggestions
Serve this pasta as a first course in the Italian style or as a main meal with a simple green salad dressed with olive oil and vinegar. A plate of bitter greens, such as radicchio or arugula, balances the squash’s sweetness without competing with the sage and cheese. Warm crusty bread is useful for any sauce left in the bowl, though the pasta should be saucy enough to eat without it.
For a fuller meal, add a side of sautéed greens or roasted broccoli. Keep additional toppings restrained: more grated Parmesan, freshly cracked pepper, or a few toasted walnuts all suit the dish. If serving several people, warm the bowls first and bring the pasta to the table as soon as it is tossed, since the sauce thickens as it cools.
Variations
Use another winter squash. Peeled pumpkin, delicata, or kabocha can replace butternut squash in the same amount by weight. Their sweetness and moisture vary, so check tenderness as they roast and add pasta water gradually. Delicata can be roasted with its tender skin on if well washed and cut into small pieces, though that gives the sauce a more textured finish.
Choose a different pasta shape. Rigatoni and casarecce catch the thicker sauce well, but fusilli, shells, or another sturdy short pasta also work. Long pasta such as tagliatelle is a reasonable choice if that is what you have; mash the squash more finely and toss thoroughly so the sauce coats the strands.
Make it dairy-free. Replace the butter with 2 tablespoons (30 ml) olive oil and omit the Parmesan, then finish with toasted breadcrumbs and a little extra black pepper. The result will be less creamy and less salty, so taste and adjust the seasoning. A dairy-free hard-cheese alternative can be added according to its package instructions.
Add a contrasting topping. Toast ¼ cup (30 g) chopped walnuts in a dry skillet until fragrant and scatter them over the finished pasta. For a little heat, use the listed red pepper flakes. These are optional additions rather than requirements; the basic version keeps the squash, sage, and Parmesan at the center.
Storage and Reheating
For food safety, refrigerate leftovers within 2 hours of cooking. Store them in a covered container in the refrigerator for 3 to 4 days. The pasta will absorb sauce as it sits, so leftovers will be firmer than freshly made pasta. If you expect leftovers, save a little extra pasta water separately only if you can chill it promptly; otherwise, use water or broth when reheating.
Reheat a portion in a covered skillet over low to medium-low heat with 1 to 2 tablespoons (15 to 30 ml) of water or broth, stirring gently until hot throughout. USDA guidance is to reheat leftovers to 165°F (74°C); check the center with a food thermometer. You can also microwave a portion in a covered microwave-safe dish, stirring midway and checking the temperature in more than one spot. Avoid prolonged high heat, which can make the pasta soft and the cheese oily.
Freezing is possible, but the pasta may become softer and the sauce less smooth after thawing. For better texture, freeze the squash sauce on its own for up to 2 to 3 months for best quality, thaw it overnight in the refrigerator, then cook fresh pasta and combine them in a skillet. Do not leave cooked pasta at room temperature for extended storage.
Frequently Asked Questions
Is butternut squash pasta a traditional Italian dish?
Italian cooking includes many pasta dishes with zucca, the Italian word for squash or pumpkin, and recipes differ by region, season, and household. This recipe uses widely available butternut squash in a simple combination of pasta, sage, butter, and aged cheese. It follows that Italian flavor tradition without claiming butternut is the one required squash or that every region makes the dish the same way.
Can I use frozen butternut squash?
Yes. Thaw it in the refrigerator and pat it dry before roasting; frozen squash often releases more moisture and may brown less deeply than fresh. Roast it in a single layer and allow extra time if needed, checking for tenderness rather than using the clock alone. If the pieces are already very soft after thawing, simmer them directly in the skillet with the broth and mash them into the sauce instead of roasting.
Can I make the squash sauce ahead?
Yes. Roast and mash the squash with the broth, butter, sage, garlic, and nutmeg, then refrigerate the sauce in a covered container for up to 3 to 4 days. When ready to eat, warm it gently in a skillet while the pasta cooks, adding a splash of water or broth to loosen it. Stir in the Parmesan and roasted squash pieces at the end for the freshest texture.
What pasta shape works best?
Short, ridged or twisted shapes such as rigatoni, mezze rigatoni, fusilli, and casarecce hold the thick sauce and small squash pieces well. Shells also catch the sauce inside. Use what you have, but avoid overcooking: pasta that is already very soft can break when tossed with mashed squash.
Can I use canned pumpkin instead of fresh squash?
Plain canned pumpkin can make a quick sauce, but it will not have the browned, distinct pieces or roasted flavor of fresh squash. Use about 1½ cups (about 370 g) plain pumpkin purée in place of the mashed squash, warm it with the butter, sage, garlic, broth, and nutmeg, and add broth gradually. Skip the roasting step and keep any remaining squash as an optional topping only if you have it.
Why is my sauce too thick or too thin?
A thick sauce usually needs more reserved pasta water, added a tablespoon at a time while tossing. If it is thin, simmer it briefly over low heat before adding the cheese, or mash a few more squash pieces into it. Keep the heat gentle after adding Parmesan; vigorous boiling can make the sauce greasy rather than smooth.
