Ingredients & Substitutions

Ingredient List

Here’s everything you’ll need:

• ½ head of cauliflower (about 350g), cut into florets
• 3¼ cups peeled, cubed pumpkin (approx. 750g)
• 1 yellow onion, diced
• 5 garlic cloves, minced
• 2 tablespoon olive oil
• 1 cup raw cashews (soaked)
• 2 tablespoon vegan margarine
• 2 tablespoon all-purpose flour
• ¼ cup nutritional yeast
• 1 tablespoon apple cider vinegar
• 1¼ cups unsweetened soy milk
• ½ cup vegetable broth
• ½ tablespoon light miso paste
• 5¼ cups elbow macaroni (dry)

Spice mix: cumin, cayenne, smoked paprika, powdered vegetable stock, garlic powder, ground coriander

Optional topping: panko breadcrumbs, nutritional yeast, salt, olive oil

Notes on Quality

For the best flavor, use fresh cauliflower and pumpkin, especially if it’s in season. If you're short on time, frozen veggies work too—just roast them a little longer to remove excess moisture. Raw cashews make the creamiest sauce, so try to soak them overnight or boil them for a quick fix.

Possible Substitutions

• Nut-free: Use sunflower seeds or silken tofu instead of cashews
• Gluten-free: Swap regular pasta and flour for certified gluten-free versions
• Soy-free: Use oat or almond milk in place of soy milk
• Pumpkin substitute: Butternut squash or sweet potato works great too

Step-by-Step Instructions

1. Soak or boil the cashews – Overnight for best results, or boil for 15 minutes if you're short on time.
2. Chop the veggies – Cube the pumpkin, cut cauliflower into florets, dice onion, and mince garlic.
3. Season & roast – Toss the pumpkin and cauliflower in olive oil and the spice mix. Roast at 390°F (200°C) for 25–35 minutes, until fork-tender.
4. Make the crispy topping (optional) – Mix panko, nutritional yeast, olive oil, and salt. Toast in the oven until golden and crispy.
5. Cook the aromatics – Sauté the onion and garlic in vegan margarine, then stir in cashews, flour, and nutritional yeast.
6. Build the sauce – Dissolve miso paste in veggie broth, then stir into the pot with apple cider vinegar and soy milk. Simmer until thickened.
7. Blend until creamy – Combine sauce, roasted pumpkin, and cauliflower in a blender. Blend until smooth.
8. Cook pasta & combine – Boil your pasta until al dente. Drain and mix with the sauce.
9. Serve it up – Top with crispy panko crumbs and enjoy warm!

Expert Tips & Tricks

Best Practices

• Roast your veggies until they're golden-brown for deeper flavor
• Always taste the sauce before blending to adjust seasoning

Common Mistakes to Avoid
