Creamy Vegan Pumpkin Pasta with Roasted Vegetables
A fully plant-based take on creamy pumpkin pasta that delivers rich, velvety sauce without dairy. Roasted Hokkaido pumpkin, bell peppers, and tomato form the base, caramelized in the oven until deeply flavorful, then blended into a naturally sweet and savory sauce. Smoked paprika adds subtle depth while fresh garlic infuses warmth throughout. The result is silky and satisfying, perfect for anyone seeking comfort food that aligns with vegan values. Serve this to impress vegetarian guests or anyone craving seasonal, vegetable-forward pasta. What sets this version apart is the no-cream approach relying on pumpkin's natural starch and plant-based creme fraiche, keeping the dish light yet luxurious. Finishing touches of fresh herbs or vegan feta add brightness and textural contrast. Ideal for autumn dinners when pumpkins peak, though adaptable year-round.

Tips
Roast vegetables in an unheated oven starting at 200C so they caramelize evenly without burning. Stir halfway through to distribute heat and prevent any charring, ensuring creamy texture when blended.
For extra richness, use vegan feta crumbles mixed into roasted vegetables before blending, or save some to top the finished dish. This adds tanginess and prevents the sauce from feeling one-note.
Crush garlic cloves gently rather than mincing so they soften and perfume the oil without breaking apart, making removal optional or leaving mellow, sweet flavor throughout the sauce.
Good to Know
Refrigerate sauce in airtight container for up to 3 days. Reheat gently with splash of plant milk if thickened. Freeze blended sauce (without pasta) for up to 2 months.
Roast vegetables up to 1 day ahead. Store cooled in fridge. Blend sauce day-of or same day for best texture. Cook pasta fresh when serving.
Serve warm immediately after tossing with pasta. Top with fresh herbs, vegan feta, or chives. Pairs well with crusty bread and simple green salad.
Common Mistakes
Skip stirring roasted vegetables halfway through to avoid burning and uneven texture.
Over-blend sauce to avoid gluey consistency; pulse until just smooth.
Add creme fraiche before roasting if substituting vegan feta to avoid seizing or separating.

FAQ
Can I use regular pumpkin puree instead of fresh pumpkin?
Yes, but reduce liquid slightly since puree is already concentrated. Use about 250g canned pumpkin puree mixed directly with roasted peppers and tomato. Roasting fresh pumpkin develops deeper, caramelized flavor that canned lacks, so roasting is preferred for best results.
What if I don't have vegan creme fraiche?
Cashew cream, coconut milk, oat cream, or blended silken tofu all work. Use same 2 tbsp ratio. Cashew cream tastes richest; coconut adds tropical notes. Avoid thick coconut cream unless diluted. Roasted vegetable starch also thickens sauce naturally without added cream.
Can I freeze leftovers?
Freeze blended sauce separately from cooked pasta for up to 2 months. Reheat sauce gently on stovetop with splash of plant milk or water, stirring often. Thaw overnight in fridge first. Pasta becomes mushy if frozen together, so assemble fresh after reheating sauce.
