How to Make Lemon Zucchini Pasta Sauce?

This recipe comes together fairly quickly, with little active cooking involved. Simple soak the cashews, roughly chop the zucchini and onion, roast the veggies, blend, and serve.

Note: The sauce will be thick. Use the pasta water to thin it out if serving immediately, or freeze and add 1 cup of water when ready to use.

Perfect for Meal Prepping!

Freeze the blended sauce in an airtight container. When you're ready to use it, just place in a pot with one cup of water and set it to medium heat, stirring occasionally. This is enough sauce for one pound of pasta.
