Save The first time I made this sauce, I accidentally doubled the garlic and honestly? It was the best mistake I've ever made in the kitchen. The whole house smelled like roasting squash and caramelized onions, and my roommate wandered in from her room asking what bakery I'd secretly opened.
Last November, when my sister was recovering from surgery and needed meals that felt like a hug, I brought over a giant batch of this. She texted me three days later asking if the recipe was some kind of family secret she'd somehow missed her whole life.
Ingredients
- 1 medium butternut squash: The sweetness develops beautifully when roasted, creating the base for that velvety texture that makes this sauce unforgettable
- 2 cloves garlic, unpeeled: Roasting them in their skins mellows the sharpness into something almost sweet and deeply aromatic
- 1 small yellow onion: These become the savory backbone that balances the squashs natural sweetness
- 1 tablespoon fresh sage: Earthy and fragrant, sage and squash were practically made for each other
- 12 oz dried fettuccine or tagliatelle: The wide ribbons catch every bit of that creamy sauce in all the right places
- 1/2 cup heavy cream: This creates that luxurious, restaurant-style consistency without any fancy techniques
- 1/3 cup grated Parmesan cheese: Adds that salty umami punch that makes the whole dish come alive
- 3/4 cup vegetable broth: Helps adjust the sauce consistency without thinning out the flavor
- Pinch of nutmeg: Optional but absolutely worth it, just a tiny pinch makes the squash taste somehow more squash-like
Instructions
- Roast the squash and garlic:
- Preheat your oven to 400°F, spread the cubed squash and unpeeled garlic on a parchment-lined baking sheet, drizzle with 1 tablespoon olive oil, season with salt and pepper, then roast for 25 to 30 minutes until the squash is tender and those gorgeous caramelized edges appear.
- Cook the pasta:
- While the squash roasts, bring a large pot of salted water to a boil and cook the pasta according to package instructions, but don't forget to reserve 1/2 cup of the starchy pasta water before draining—that liquid gold saves sauces.
- Sauté the aromatics:
- In a large skillet over medium heat, warm the remaining tablespoon of olive oil and cook the diced onion and chopped sage for about 4 minutes until the onion is soft and your kitchen starts smelling incredible.
- Blend the sauce:
- Squeeze those roasted garlic cloves right out of their skins into a blender, add the squash, sautéed onion and sage, vegetable broth, and heavy cream, then blend until everything transforms into the smoothest, most gorgeous orange sauce you've ever seen.
- Finish and serve:
- Pour the sauce back into the skillet over low heat, stir in the Parmesan and that optional pinch of nutmeg, season generously, then add the pasta and toss until every strand is coated, adding pasta water if needed to reach the perfect consistency.
Save Now this is the pasta I make when I want something that feels special but doesn't require three hours of active cooking time. Last month, my partner actually asked if we could have it twice in one week, which is basically the highest compliment a home cook can receive.
Making It Your Own
I've found that adding a handful of baby spinach right at the end makes it feel a little more substantial, and sometimes I'll toast some walnuts to sprinkle on top for that perfect crunch contrast. The sauce is also incredibly forgiving—it reheats beautifully for lunch the next day, which might actually be even better than fresh.
The Vegan Version
When I made this for my plant-based friend, I swapped in full-fat coconut milk and nutritional yeast, and honestly? It was so good I started preferring it that way myself sometimes. The coconut adds this subtle richness that plays surprisingly well with the squash.
What To Serve Alongside
This pasta is rich enough to stand on its own, but a simple arugula salad with lemon vinaigrette cuts through the creaminess perfectly. I've also learned that a crisp white wine like Pinot Grigio isn't just optional pairing—it's basically required.
- Keep some extra Parmesan at the table because everyone will want more
- The sauce freezes well if you want to meal prep for busy weeks
- Don't skip the fresh parsley garnish, it makes the whole dish look professionally finished
Save There's something about this dish that turns a regular Tuesday dinner into a tiny celebration, and sometimes that's exactly what we need.
