If pasta in a creamy, dreamy pumpkin sauce sounds good to you, you will love this vegan Pumpkin Mac and Cheese made from real Hokkaido pumpkin, not pumpkin purée.
Put the pumpkin cubes on a baking tray lined with parchment paper. Drizzle them with olive oil. Mix well until coated evenly. Spread them out. Add roughly chopped yellow onion. Bake at 400°F/200°C for about 30-35 minutes until slightly brown and soft.
Meanwhile, boil the pasta. (Save the pasta water for the pumpkin sauce)
Blend cashews and water in a blender to make cashew cream.
Into the cashew cream, add the roasted pumpkin, onion, and salt. Blend. Add more and more pasta water until it is thin enough to pour. I added 2/3 cup of pasta water.
Pour the pumpkin sauce over the drained pasta and mix well! And it's ready to serve. I've added chopped fresh parsley on top.
