Is Zucchini Keto? Carbs, the Water Trick & Best Swaps

Yes — zucchini is keto. A cup has about 2g net carbs, which makes it the closest thing keto has to pasta. The only catch is the water, and managing it is the difference between zucchini that works and a soggy mess on your plate.

Zucchini is my go-to for replacing the starchy stuff: noodles, lasagna layers, even bread. Below: the carb numbers, the water trick nobody tells you, and how I actually use it.

How many carbs are in zucchini?

At about 2g net carbs a cup, zucchini is one of the few vegetables you can eat in real volume on keto without watching the number. A whole medium one is still only around 4g net, so it’s the rare low-carb veg you don’t have to ration.

The water problem (and the fix)

Here’s what trips people up: zucchini is more than 90% water, and that water has to go somewhere. Skip this step and your zoodles sit in a puddle and your lasagna turns to soup. The fix is simple but not optional: slice or spiralize it, salt it, and let it sit 10 to 15 minutes, then squeeze the liquid out in a clean towel before it goes anywhere near a hot pan. I’ve made watery, sad versions of every zucchini dish there is, and every single time it came down to skipping the salt-and-squeeze.

How I use zucchini on keto

Three swaps earn it a permanent spot in my fridge: spiralized into zoodles for any pasta dish, sliced thin into planks for lasagna in place of noodles, and grated into keto zucchini bread (where, conveniently, you want some of that moisture). It also fries well into keto “fries” and chips once you’ve pulled the water out.

How much zucchini can you eat on keto?

As much as you reasonably want. At 2g net carbs a cup it’s hard to overdo, and it’s mostly water and fiber, so it fills you up for almost nothing. It’s one of the few foods on keto where I never think about the carb math.

I’ve gathered every way I cook with it, water trick and all, in one place:
