Ingredients

For the Pasta and Sauce

• 1 whole butternut squash (about 2lb/1kg)
• 1 red onion (quartered)
• 1 large head garlic (halved horizontally)
• 120 ml heavy cream (double cream)
• 40 g Parmesan (finely grated, plus extra to serve)
• 350 g pasta of your choice (like bowtie, rigatoni, fusilli, or penne)
• olive oil
• salt to taste
• freshly ground black pepper to taste

For the Brown Butter and Sage

• 30 g butter
• 8 fresh sage leaves

The roasted butternut squash forms the base of the sauce, while roasted garlic and red onion add savory depth. Parmesan gives the sauce a salty, nutty finish. Pasta water is also important because it can loosen the blended sauce and help achieve the desired consistency.

How to Make Creamy Butternut Squash Bowtie Pasta

1. Prep and roast the vegetables

Preheat your oven to 190°C (170°C fan).

Halve the butternut squash lengthwise, scoop out its seeds, and score the flesh in a crisscross pattern.

Place the squash flesh-side up in a baking tray. Drizzle the halved garlic head with olive oil, wrap it in foil, and place it on the tray with the squash.

Roast the squash and garlic for 25–30 minutes.

Then add the quartered red onion to the tray, tossing it lightly in the oil from the squash. Continue roasting for another 20–25 minutes, until the squash is tender and caramelized.

2. Blend the sauce

Scoop the roasted squash flesh into a blender along with the roasted onion.

Squeeze the soft roasted garlic cloves into the blender. Add the heavy cream and blend until the mixture is smooth and creamy.

If the sauce is too thick, add a small splash of pasta water and blend again to achieve a velvety texture.

Season with salt and freshly ground black pepper.

3. Cook the pasta

Bring a large pot of salted water to a rolling boil.

Cook your pasta of choice until it reaches al dente perfection.

Reserve some pasta water before draining so you can adjust the sauce consistency later.

4. Brown the butter and fry the sage

In a large frying pan over medium heat, melt the butter until it begins to foam.

Add the sage leaves and fry until the butter turns golden brown and the sage is crispy and aromatic.

Transfer the crispy sage leaves to a plate lined with kitchen paper to drain.

5. Combine the pasta and sauce

Reserve half the brown butter in a small bowl.

Add the drained pasta to the pan with the remaining brown butter, tossing to coat evenly.

Pour in the butternut squash sauce, add most of the grated Parmesan, and toss everything together.

Use a splash of pasta water to loosen the sauce as needed.

6. Serve

Divide the creamy butternut squash bowtie pasta between bowls.

Top with the crispy sage leaves, additional grated Parmesan, and a drizzle of the reserved brown butter.

Serve warm and enjoy.

Important Cooking Tips

• Roast until the squash is tender and caramelized. This is an important part of developing the flavor of the sauce.
• Watch the roasting stages: The squash and garlic roast for 25–30 minutes before the onion is added for another 20–25 minutes.
• Save pasta water: Keep some before draining so you can adjust the sauce if it becomes too thick.
• Blend the sauce thoroughly: The goal is a smooth, creamy consistency before combining it with the pasta.
• Watch the brown butter: The butter should become golden while the sage turns crispy and aromatic.
• Reserve the brown butter: Half is saved for drizzling over the finished pasta.
