Butternut Squash & Farro Casserole

We’re giving casseroles an update with sophisticated and healthy ingredients perfect for any modern home cook!

This month, we’re featuring the incredible fall veggie, butternut squash. Of course, I didn’t always think it was incredible, which I talk about here. It seemed too high-maintenance to deal with, but then I discovered a simple way of prepping it that made it a mainstay in my fall grocery list. (You can watch the secret to prepping butternut squash with the video below.)

Now I experiment with many ways to cook this veggie. Last week, I paired it with another fall favorite, brussels sprouts, for the ultimate fall side dish. Today, we’ll be adding it to a hearty, healthy casserole.

I know what you’re thinking: Casserole? Isn’t that something women made in the 60’s?

Yes, it’s true, but this casserole (or bake) has been updated with sophisticated and healthy ingredients for the modern cook. It features one of my favorite grains, farro (sadly not gluten-free, but millet would be a great gluten-free substitute).

The chewiness of the farro combined with the creaminess of the butternut squash are a great balance of textures (plus, it’s fiberlicious). I’m a dairy fiend so I also use creme fraiche and lots of cheese in this dish to add richness and make it an extra satisfying winter-night meal.

If eating as a side, consider pairing with a bowl of bean soup, and you’ll have all your nutrition categories check off.
