This healthy plant-based recipe may make me feel like I am winning at meatless Mondays, but honestly, it’s pretty simple. There’s really nothing too fancy going on here—just a clean, hearty, and super tasty squash and kale casserole.

If you really want to feel on trend though, definitely try preparing this casserole with kabocha.

If you’re not in the know on kabocha and it sounds like I’m speaking another language, it’s because I am. Kind of.

Kabocha is a tasty Japanese winter squash. It has a fluffy texture and a sweet, earthy flavor that can be compared to pumpkin mixed with sweet potato. Um, yum!

Meanwhile, like most of those orange superfoods, you’ll find plenty of vitamin C, iron, and beta-carotene in this Japanese squash.

If you love squash, you’ll definitely want to give kabocha a try. And if you find you’re often on the fence about squash (like me) you may just find your squash of choice in the Japanese pumpkin.

Of course, if you’re not a fan or you just can’t find it at your local supermarket, butternut squash will work just as well in this recipe.
