Butternut Squash Rice Casserole is a warm and cozy Fall meal that’s very easy to make and it’s packed full of flavor and texture. It’s a great dish to serve to a crowd, and you can choose to serve it as a main course or a side dish.

There’s nothing better than a warm and rich casserole for dinner ESPECIALLY when said casserole is prepared with arborio rice plus butternut squash and a sprinkle of cheese. eeek! 😋 

I’m always in danger of turning into my Mother, especially around the kitchen. There’s not one recipe of hers that I do not love, and, with a few modifications, this recipe is no exception.

Wednesdays and Fridays were always meatless at our house, and if Mom couldn’t top her rice casseroles with chicken thighs, veggies were the next choice. But, it was never squash. In fact, growing up, squash was something we enjoyed roasted and sprinkled with lots of sugar — and in the Fall.

Well, now that it’s 2019 and not 1999, I am in charge of this kitchen and lemme tell you; a squash’s bestie should always include rice. Hands down. Don’t fight me, I’m convinced.

Similar to risotto, but not quite a risotto since you don’t have to stir endlessly, this hearty casserole provides a nice alternative to plain rice side dishes and is way healthier than those pre-packaged rice mixes.

To make it, you’ll need arborio rice, chicken broth, butternut squash, garlic and some herbs.

  1. First, get your beautiful Dutch Oven out and fry up some onions, cubed butternut squash, and garlic in it. 
  2. Stir in some rice and thyme; cook for few minutes.
  3. Add vegetable broth and bring to a boil.
  4. Cover and bake in the oven at 400˚F for 20 minutes.
  5. Remove from oven, add cheese, give it a stir, and serve!

This is a rice dish cooked mostly in the oven, but the texture is close to a risotto. It’s not mushy, but it is a soft, fluffy, and textured casserole allowing us to taste each of the flavors separately.

The butternut squash adds a sweet flavor to the dish and is bountiful this time of year. In the Fall, grocery stores often carry pre-cut butternut squash cubes, which saves significant prep time. However, I prefer to buy a whole squash and make my husband chop it up for me. 😀

You can serve this casserole as a side dish to chicken, pork, or turkey, but can also be served as a hearty vegetarian main dish.

    Yum! I’m making this tomorrow for my lunches this week! Love it and I could add some great sides to it, too, if I choose!

    I served this alongside a pork roast and it was delicious! It is certainly hearty enough to be a yummy me on it’s own too!

    Now, if only my microwave hadn’t died a bright & sparking death a couple of weeks ago! Any idea how long I’d have to bake/roast it first (Or saute it on the stovetop)?

      Yes, you can definitely roast it. Place butternut squash on a baking dish, cut-side UP; brush squash with olive oil and season with salt and pepper; then, roast at 375˚F for 40 to 45 minutes, or until fork tender. OR you can also get pre-cut squash: season with salt and pepper; toss with a tablespoon of olive oil and roast on a baking sheet for 30 minutes at 400 degrees F.

    What a fun rice casserole. I have two 4lb. butternut squashes that I need to figure out what to do with…
