Vegan roasted pumpkin alfredo topped with toasted walnuts and crispy sage leaves. The recipe is minimal fuss but has maximum flavour!

Unlike North America, pumpkin isn't a huge thing in Australia. However, it's by far my favourite vegetable as it's naturally sweet, satiating and can be used to make the creamiest soups, pastas and desserts.
I swear by butternut pumpkin (which other countries call 'butternut squash'). In my opinion, it's the most sweet, creamy and robust out of all pumpkin varieties. I've tried roasting all the other types and they just don't do justice! Plus, whenever I eat butternut pumpkin, I think of creamy butter haha.

This cozy vegan pumpkin alfredo recipe is:
- Nut free
- Easy
- Packed with flavour
- Very customisable
All you need to do is roast all the pumpkin, garlic and onion in the oven. Pop it in a high powered blender with the rest of the ingredients then combine the luscious sauce with your pasta!
The vegan pumpkin alfredo sauce will complement all types of pasta. I used rigatoni but have enjoyed it with spaghetti, ravioli and pasta shells :).

Some extras...
If you're feeling extra fancy or have dinner guests over, I'd recommend toasting some walnuts and sage on a frying pan. The walnuts and sage will become crispy and aromatic and add extra depth to your pasta.
If you want to make this recipe in advance, I'd recommend keeping the sauce separate from the pasta to prevent the pasta from getting soggy (especially if you use gluten free pasta). Simply add both the sauce and pasta to a saucepan to reheat.

Just made your ramen recipe. Yum. Now I am on the hunt for all your golden Yums. I have a question on this recipe. Can I use frozen butter squash? That’s what I have at the moment.
So glad you enjoyed the ramen recipe! And yes, you can definitely use frozen butter squash 🙂
I’m allergic to cashews and pecans. What can I substitute?
Maybe try blanched almonds or macadamia nuts? If not, a smaller portion in silken tofu or coconut cream will work.
Will this work if I swap pumpkin for butternut squash?
Yes, I used butternut squash! (In Australia, butternut squash is a type of pumpkin)
