How to Make It – Ingredient List & Instructions

Ingredients (serves ~4‑6)

• 1 medium butternut squash, peeled, seeded, and cubed
• 1 yellow onion, chopped
• 2‑3 cloves garlic, minced
• Olive oil
• Vegetable or chicken broth (or pasta water)
• Fresh herbs like sage or thyme (optional but lifts flavour)
• Salt and pepper to taste
• Optional: parmesan cheese, nutritional yeast or vegan cheese for richness
• Pasta of your choice

Instructions

1. Preheat oven to about 200‑220 °C (400‑425 °F).
2. Toss the cubed squash with olive oil, salt, and pepper. Spread on a baking sheet and roast until tender and caramelized (about 25‑30 minutes). Optionally, roast the onion too for more flavour.
3. While squash roasts, cook pasta al dente. Reserve some pasta water before draining.
4. Once squash is tender, blend squash, roasted onion/garlic (if used), broth (or pasta water), herbs, and any optional richness like parmesan or nutritional yeast. Blend until smooth. Adjust consistency with more liquid if needed.
5. Toss sauce with cooked pasta. If needed, use reserved pasta water to loosen and help sauce coat the pasta well. Season to taste.
6. Serve with fresh herbs, a sprinkle of cheese or vegan alternative, and freshly ground pepper. Optional: roast or sauté some veggies (broccoli, kale) as a side or mix‑in.

Tips & Variations

Make it vegan / dairy‑free

Skip the parmesan or replace with nutritional yeast or a plant‑based cheese. Use pasta water or broth instead of cream. Roasting gives such flavour you likely won’t miss the dairy.

Add texture or flavour boosts

Try adding sage or thyme, lemon zest, black pepper, roasted garlic. Throw in roasted vegetables or wilted greens for more colour and nutrition. Finish with a bit of crunchy topping or shaved cheese.

Frequently Asked Questions

How do I avoid watery sauce?

Roast squash until it’s nicely caramelized; that dries it out and concentrates flavour. Don’t add too much liquid at first—reserve pasta water and add gradually until you get your preferred texture.

Can I use frozen butternut squash?

Yes. Thaw, drain any excess moisture, then roast or sauté. The flavour may be slightly different but still delicious.

How long does the sauce last, and can I freeze it?

Refrigerate in an airtight container for about 4‑5 days. Freeze portions for up to 3 months. To use, thaw and reheat gently, adding a little liquid if needed.

What types of pasta work best?

Shapes that hold sauce well are great—rigatoni, penne, rotini, or even filled pasta like ravioli. Long pasta like linguine works too. Whole grain or gluten‑free options also work.

Conclusion

Creamy Butternut Squash Pasta Sauce is your new weeknight hero: rich, flavorful, and way easier than a full cream sauce. Whether you want comfort, flavour, or something you can make ahead, this sauce delivers. Toss with pasta, herbs, maybe a sprinkle of cheese, and enjoy something cozy tonight.
