Recipe FAQs

What’s the best way to soften butternut squash?

From my experience, the best way to get a creamy squash that melts in your mouth with each bite is to bake it in the oven. Whether it be roasting it or baking it into a casserole like this one, the oven helps bring out the best caramelized flavor and creamy texture in the butternut squash.

Do you need to peel butternut squash?

Technically you don’t have to, but I personally prefer to peel the thin skin to make it more creamy and easy to chew. 

How do you keep squash casserole from getting watery?

This recipe uses dry rice and the perfect amount of vegetable broth so everything gets absorbed by the end, leaving you with the perfect casserole texture. 

Is this recipe good for meal prep?

Yes! This recipe is great for making ahead of time, plus you can divide it into portions and freeze it for up to 2 months.

    1. Hi, Julie. Since spinach cooks relatively quickly, it’s best to add it in during the reheating process rather than including it in the casserole before refrigerating. This will help prevent the spinach from becoming overcooked and mushy. Simply reheat the casserole until it’s warm, then stir in the spinach until it’s wilted and evenly distributed throughout the dish. This way, you’ll maintain the texture and flavor of the spinach while reheating the casserole.

    Absolutely loved the rosemary garlic cashew cream! This is such a simple and delicious recipe. I will definitely make this again; Thanks for sharing.

    This dish is one of my favorites—I thought the beans would add a weird texture but this is absolutely delicious. Don’t be shy with the cashew cream!!

  3. What capacity casserole dish would you need for this? I just have a round cast iron one – do you think it would take longer to cook in cast iron versus ceramic?

    1. Hi Esther, A 9×13-inch casserole dish, like the one we used in the recipe, typically has a capacity of around 3 quarts to 4 quarts, depending on its depth. This size is a common and versatile choice for many casserole recipes, and it’s often referred to as a “standard” or “large” size.

      A round cast iron casserole dish should work well for this recipe. While cast iron may take a bit longer to heat up, it retains heat well and distributes it evenly. The cooking time might vary compared to ceramic, so it’s advisable to check the casserole a bit earlier than the recommended time to ensure even cooking. Keep an eye on the dish towards the end and use a toothpick or fork to check the doneness of the brown rice and tenderness of the butternut squash. Overall, cast iron should work well for this recipe, providing good heat retention and potentially creating a nice crust on the bottom.

    SO GOOD! My husband and I are not vegan but we are trying to get more plants and plant-based meals in our diet. This is one of our favorite fall and winter meals. It is just so freaking good!!!! I cannot describe how yummy this is. It is so warm and nourishing. I have found that we prefer to add 1.5-2x the amount of kale.

    I made it today and it was very nice, I used one can of cannellini and one of butter beans and it turned out good anyway! (My 3 y old is a picky eater but she ate the entire portion!)
    I absolutely love all your dumb and bake, I’m a staying at home mom and these meals are such a help! Please make more 😂 something Indian perhaps? I would love something like a curry or daal😍

    1. Glad you and the little one liked the recipe! We have curry recipes on the blog too! Just enter “curry” in the search bar.

    My husband is very picky but he converted to vegetarian because of health reasons and he LOVES this dish. I didn’t have butternut squash the second time I made it so I used sweet potato and fresh spinach and it was fantastic too! Thanks for a great dish!!

  7. 5 stars
    This dish was so easy to throw together and tasted great! I was nervous some rice would be crunchy but it was perfect. The rosemary garlic cream sauce is a great addition and, in my opinion, is a MUST. Definitely adding this to the meal rotation for winter!

      1. You can use frozen butternut squash in this recipe by thawing it first and then cubing it into bite-sized pieces. Once thawed, you can follow the recipe as written, adding the thawed squash to the casserole dish along with the other ingredients. Keep in mind that frozen squash may release more liquid during cooking, so you may need to adjust the cooking time or reduce the amount of vegetable broth added to prevent the casserole from becoming too soupy.
