Bake for 20 minutes or until the vegetables are golden brown and tender. Keep an eye on them to avoid any bitterness; they should be fragrant and caramelized.

Butternut Squash Pasta Sauce Recipe FAQs
How do I select the best butternut squash?
Absolutely! If you opt for fresh butternut squash, look for ones that are heavy for their size with a smooth, tan skin. Avoid any that have dark spots all over or soft spots. The size isn’t crucial, but a uniformly shaped squash will make slicing easier.

When you’re ready to enjoy it again, simply thaw it overnight in the fridge and then reheat gently on the stove.
What should I do if my sauce turns out too thick?
