Clean Eating Butternut Rice Casserole Recipe

This clean eating butternut rice casserole is a delicious side dish, or even a plant-based main meal!

I’ve had a butternut squash sitting on my counter for a while now and I knew that if I didn’t use it soon, it would be going in the trash. Well I’m not one to waste food, so I decided we were going to have it for dinner. But truth be told, I’ve made butternut squash a million different ways this season and I was bored with every single one of them.

I wanted something hearty, filling and somewhat on the creamy side. But since I don’t eat dairy, I figured I’d substitute with cashew cream. So I decided on this clean eating butternut brown rice casserole. It was perfect for dinner and I was able to eat off of it for a few days!

Cashew cream is a wonderful dairy-free substitution for anything you would usually want to make creamy. In fact, one of the main takeaways from my plant-based culinary program was that I should ALWAYS have a bowl of cashews soaking in the fridge because frankly, it’s never a wrong time to add cashew cream to something you are making. Seriously. It goes with just about everything!


The trick with cashew cream is to always have a bowl of cashews soaking in the fridge. That being said, you can’t leave them in there forever. So if you soak them overnight but don’t want to use them right away, simply strain off the water, transfer the cashews to a freezer-safe container and keep them in the freezer until you are ready to use them. So simple!!

  • Add plenty of water for soaking. Cashews will nearly double in size when done soaking and they should still be covered in water at that point.
  • Use ONLY raw cashews. They absolutely must be raw.
  • Freeze for up to 6 months after draining.
  • Note that to get a truly creamy texture, you’ll need a high powered blender like a Vitamix. If you don’t have one, your cashew cream will be a little less creamy. Still good, but you’ll be able to detect some of the cashew bits in the cream. Not necessarily a bad thing, just a difference worth noting.

  • If you make your cashew cream ahead of time and dice all your ingredient first, this dish comes together super fast and easy!
  • If you bake it and the liquid is gone but something isn’t cooked, feel free to add about another 1/2 to 1 cup of liquid and continue baking until done. There should be no liquid left in the dish when it’s finished.
