The smooth butternut squash pasta combines sweet roasted squash with fragrant herbs in a silky sauce. This cozy meal turns basic ingredients into something truly special, showing that good-for-you food can taste amazing too. When butternut squash gets blended up, it makes this incredible creamy coating that hugs every bit of pasta, while fresh sage and thyme bring warmth and depth to each mouthful.
I made this pasta for my family gathering last Sunday, and my super fussy nephew couldn't stop eating it. My trick was to roast the squash until it got those brown edges, which brought out all its sweetness and made the sauce extra smooth.
Key Ingredients Breakdown
- Butternut Squash: Go for one that's heavy with smooth skin. The orange inside should be bright - that means it'll be sweeter
- Shallots: Pick ones that aren't soft and still have their papery covering. They're milder than regular onions
- Fresh Garlic: Look for tight, uncracked bulbs. The flavor beats the stuff that comes in jars
- Raw Cashews: These make everything creamy. Buy whole ones without salt for best results
- Nutritional Yeast: Gives that cheesy taste without cheese. Keep it somewhere dark and cool
- Balsamic Vinegar: The older the better - it brings a sweet richness
- Fresh Herbs: Get bright, unwilted sage and thyme for the strongest flavor hit
Crafting Your Meal
- Squash Prep:
- Put butternut halves on a parchment-lined tray. Pour plenty of olive oil over them. Lay them cut-side down for extra browning. Bake until they're totally soft when poked.
- Flavor Builders:
- Wrap garlic and shallots in aluminum foil like a little package. Add a splash of olive oil so nothing sticks. Roast alongside your squash to build deep flavors.
- Blending Time:
- Dump roasted veggies into your blender. Add cashews that have been soaked and your seasonings. Start blending slowly, then speed up. Pour in liquid bit by bit until it looks right.
- Noodle Know-How:
- Boil pasta in extra salty water until it's still got a bit of bite. Save some cooking water before draining. That starchy water is the secret to amazing sauce.
- Putting It Together:
- Put pasta back in the pot. Pour your blended sauce over. Stir while adding splashes of the saved pasta water. Keep going until every noodle is perfectly coated.
Everyone in my house goes crazy for the roasted garlic in this dish. It gets so mellow and sweet, making the whole sauce taste amazing. My kid begged for this pasta three times in one week last month, saying the roasted garlic made it taste just like we'd ordered takeout from a fancy place.
Tasty Companions
Make this a full meal with some crusty bread and a simple arugula salad on the side. When you want to impress, add some balsamic-glazed Brussels sprouts too. A cold glass of white wine tastes great with the creamy sauce. Try sprinkling some toasted pine nuts on top for a nice crunch and nutty flavor.

Flavorful Variations
Mix things up by tossing in some roasted mushrooms for an earthy taste. Swap regular pasta for zucchini noodles if you want something lighter. Throw in some slow-cooked onions for extra sweetness. Need protein? Add some grilled chicken pieces or crispy chickpeas. Want to get fancy? Use butternut squash stuffed pasta instead of plain noodles.
Storage Smarts
Keep any leftovers in a sealed glass container in the fridge for up to four days. When you warm it up, add a little veggie broth to keep it creamy. Heat it slowly on medium-low, stirring now and then. You can freeze just the sauce in freezer containers for up to two months. Let it thaw in the fridge overnight before you use it.
Squash Benefits
Butternut squash packs tons of vitamins while staying low in calories. All that fiber makes this pasta really filling. It gets even sweeter when you cook it at high heat. Fall squash usually tastes best, but you can find good ones all year round.
Year-Round Ideas
In summer, make it lighter with fresh basil and tiny tomatoes. Winter versions taste great with parsnips added in. Spring calls for fresh peas and mint. You can switch up the herbs based on what's growing, but keep cooking it the same way.
Finishing Touches
Sprinkle your pasta with crispy sage leaves cooked in olive oil. Add some toasted breadcrumbs for a nice crunch. Drizzle good olive oil and scatter fresh herbs right before serving. For special dinners, try adding some shaved Parmesan or a few drops of truffle oil.

This butternut squash pasta hits the spot when you want something cozy that still feels good to eat. Every time I cook this, I'm amazed how simple whole foods can turn into something so tasty. The mix of sweet squash, fragrant herbs, and creamy cashews gives you a meal that satisfies comfort food cravings but doesn't leave you feeling heavy. It's become my go-to dish, especially when the weather turns cold and we all need something warm and comforting to eat.
