Butternut Squash Pasta Sauce Recipe FAQs
How do I select the best butternut squash for this recipe?
Absolutely! When choosing butternut squash, look for ones that feel heavy for their size and have a smooth, tan skin without any dark spots or blemishes. The skin should be firm and matte, indicating freshness. If you’re using frozen, ensure there are no excessive ice crystals or frost in the bag, as this can affect texture.
How should I store leftover butternut squash pasta sauce?
Very! Allow the sauce to cool before transferring it to an airtight container. In the fridge, it can stay fresh for up to 3 days. For best reheating results, warm over low heat, adding a splash of reserved pasta water to restore its creamy texture.

When you’re ready to enjoy it, reheat gently on the stovetop, adding a bit of olive oil or pasta water for a smooth consistency.
What if my sauce is too thick after blending?
No problem! If your butternut squash pasta sauce turns out thicker than you’d like, simply stir in additional reserved pasta water or a splash of vegetable broth gradually. Blend again until you reach your desired consistency, ensuring each addition melds well into the sauce.
