This creamy zucchini pasta is one of my favorite quick meals when zucchini is in season and the pantry needs a clean-out. It is rich without feeling heavy and turns humble ingredients into a beautiful plate of comfort. The sauce is unbelievably smooth thanks to starchy pasta water and a good blend, and the nutty topping gives it an extra kick.
I keep this recipe on repeat during late summer when zucchini overflow from the garden and I want a cozy dinner with minimal effort.

Storage Tips
Store leftovers in a sealed container in the fridge for up to three days. When reheating stir in a splash of water or plant milk to restore the silky sauce texture. Avoid microwaving too long as the pasta can overcook.
Ingredient Substitutions
No zucchini on hand Use yellow squash or pattypan in equal measure. You can even mix two types of squash for a more colorful presentation. For the cream base a thick oat milk works if vegan cream is not available.

Serving Suggestions
Add wilted spinach or kale to the finished pasta for extra greens. Roasted cherry tomatoes can bring a bit of acidity to balance the richness. Serve with toasted sourdough or a crisp green salad.
Cultural Context
