Zucchini pasta sauce. Easy doesn’t begin to describe this slow cooked zucchini pasta sauce, inspired by the one made famous by Meghan Markle. Regardless of whether you are Team Meghan, Team Kate, or Team Couldn’t-Care-Less-Either-Way, this recipe is absolutely going to make you Team Zucchini.

The popular green summer squash that overwhelms most gardeners is truly the star in our zucchini pasta sauce. The original recipe uses very few ingredients and we’re sure that it is delicious, because the zucchini really is the base of this dish. We think we’ve taken something great, and made it even better however! We start with sautéing shallots and garlic, adding the heat of some chili flakes, using vegetable stock powder to keep the whole thing plant-based, and then refreshing the meal with grated lemon zest just before serving. That bright punch of fresh citrus flavour is absolutely perfect!

Despite this recipe being as simple as can be, you do need to plan. You will need to cook this sauce for a long time; four hours is not an exaggeration, although you may be able to get away with three hours. This long cooking, over low heat, will treat your zucchini so well. They will soften, they will release their water, they will dissolve and turn into a glorious mush. Certainly not the most elegant meal to look at, the buttery, smooth and luxurious taste and texture of your zucchini pasta sauce will have you think it’s the most beautiful thing in the world.

Helpful hints

What kind of zucchini is used in zucchini pasta sauce?

We use green zucchini in this recipe, as does the original. although you could theoretically use yellow zucchini instead, or even a combination of the two. Regardless of the colour, because you will not be peeling your zucchini, be sure to wash it well, buy organic if you can (or better yet, grow it yourself!), and avoid any squash that is obviously bruised, or brown. Also, don’t use too large zucchini – those tend to have seeds.

How much water to add to the zucchini sauce?

We start with 2 cups of water when cooking our zucchini sauce for pasta, and typically have to add a little bit more to avoid burning our sauce. If you find that you have too much liquid left in the pot after 4 hours, cook your sauce a little longer with the lid off of the pot. Watch it carefully though – you don’t want your zucchini to stick to the bottom of the pot and burn.
