Butternut Squash Quinoa Casserole is one you don't want to miss! This recipe works just as well as a weeknight standby as it does on your holiday table. Have fun with it and adapt it to suit your needs - adding in cooked chicken or tempeh is an excellent way to up the protein factor, or you can add sauteed spinach for more vegetables.
This time of year, I want to eat meals that leave me feeling my best. The challenge is that the weather has me craving comfort food.
Today’s casserole is my favorite kind of vegetarian main dish. Flavor packed, hearty, and cheesy.
It takes butternut squash casserole to a whole new level!
To me, it is the perfect example of comfort food that you don’t have to feel guilty about enjoying.
Did you know that just one cup of butternut squash has 160 percent of your recommended amount of vitamin A?
Vitamin A is important to keep your immune system, skin and eyes in good shape. It also happens to be really good for your gut. It is needed to help the body assimilate nutrients.

Ingredients
- Butternut Squash - I like to buy a whole butternut squash and peel and dice it, but you can buy pre-chopped butternut squash in the produce section if you are short on time. Frozen chopped squash also works in a pinch!
- Olive Oil - Any oil you choose, such as avocado oil, will work.
- Shallots - If you don't have shallots, ½ cup of chopped red onion would be a good substitute.
- Sage - I encourage you to stick with fresh sage here - dried just doesn't compare. If dried is your only option, I would recommend ½ teaspoon.
- Garlic - I know that six cloves of garlic seem like a lot, but it really adds to the dish's flavor. If you don't care for garlic, feel free to reduce the amount used.
- Quinoa - You will need one cup of uncooked quinoa for this recipe. I like white quinoa as I find the texture of red quinoa a bit too firm for casseroles. You decide what works for you.
- Broth - I prefer to make my broth homemade using vegetable scrapes because I feel that the flavor is superior to any commercially available broths. Do whatever works for you!
- Salt and Pepper - My preference is for finely ground pink Himalayan sea salt and fresh ground black pepper
- Cayenne Pepper - This adds a subtle kick of heat, which I don't find to be at all overpowering. If heat is not your thing, feel free to leave it off.
- Eggs - I use large eggs. If you are vegan or allergic to eggs, just leave them off.
- Milk - Any kind of unsweetened milk will work in this recipe.
- Cheese - If you are not vegan, Gruyere cheese is exceptional here. If you don't have it, use whatever cheese you have on hand. For a vegan option, either use gluten-free breadcrumbs or vegan cheese.
How to Make Vegetarian Quinoa Butternut Squash Casserole
This is a visual walk through for those who like to see the steps. For the full recipe, see the recipe card below.
Step 1: Gather Your Ingredients
You will need diced butternut squash, olive oil, minced shallots, chopped sage, garlic, quinoa, broth, salt, pepper, cayenne pepper, eggs, milk, and cheese.
Step 2: Roast the Squash
Preheat the oven to 350 degrees. Prepare a baking sheet by spraying with oil. You can line it with parchment if you choose. Add the squash and season with salt and pepper. Roast for 15 minutes.
Step 3: Cook shallots, sage and garlic.
When the squash has been in for about 8 minutes, heat oil in a saucepan over medium heat. Add shallots and sage and cook for 8 minutes. Add in garlic and cook for another 30 seconds.
Step 4: Add Quinoa and Butternut Squash
Add the quinoa and butternut squash to the pan with the shallots and cook for another minute.
Step 5: Add Broth and Seasonings.
Add in the broth, salt, pepper and cayenne pepper. Bring the mixture to a simmer, and then reduce the heat to low. Cover and cook for about 25 minutes, until the liquid is absorbed.
Step 6: Transfer to a Baking Dish and add Eggs and Milk.
Transfer the butternut squash mixture to a baking dish. Whisk together the eggs and milk and pour the liquid over the quinoa and butternut squash mixture.
Step 7: Top with Cheese and Bake
Top with grated cheese and bake. If desired, broil for 2 minutes to brown the top.

Frequently Asked Questions
Yes! One of the best ways to prep for the holidays or the busy work week is to prepare casseroles ahead of time. This quinoa casserole may be made up to two days before baking. Allow to sit at room temperature for at least 30 minutes before putting in the oven. Alternatively, place in a cold oven and allow the pan to warm as your oven preheats.
Yes! This casserole may be frozen before or after baking. To freeze, allow to cool completely and then wrap tightly. Prior to cooking or reheating, it is best to let the casserole thaw in the refrigerator.
Butternut squash can safely be stored at room temperature in a dark space for up to a month.
Variations for Butternut Squash Quinoa Casserole
- For add a nutritional punch, add in 8 ounces of sautéed spinach or kale before baking.
- For a more traditional “holiday feel” Butternut Squash Casserole, omit the cheese. Instead mix ¼ cup melted butter, ¼ cup brown sugar, ½ cup toasted pecans, ½ cup oats and ¼ cup flour. Sprinkle on top of the casserole before baking.
- Saute 6 ounces chopped mushrooms and add to the mixture prior to baking.
Make it Easier
- If you are pressed for time you can buy pre-cut butternut squash in the produce section. You can also find it in the freezer section. While this is a time saving option, you should expect package squash to have an inferior texture and taste to that which you peel and cut yourself. You decide if the trade-off is worth it!
- Buy shredded cheese. Again, I do find there is a bit of a trade off in flavor, but this is a great option for when you are pressed with time.
Tips for Making Butternut Squash Casserole Recipes
- This makes a great side dish or vegetarian main course. To make this vegan, omit the eggs and add in an additional ¼ cup of nut milk. If you would prefer to skip the vegan cheese, breadcrumbs work great here too.
- I recommend using the best quality cheese you can here. A good Gruyere really adds a lot of flavor!
Buying Butternut Squash
The exterior of butternut squash should be very hard and free from any soft spots. It should feel heavy for its size.

Love this! Easy and delicious, the meat eaters I cooked for loved it too. I subbed aquafaba for the egg and used panko breadcrumbs to top. This one is definitely going to be a regular, thank you!

So glad you enjoyed it!

Hi Wendy, I just made this tonight, it is a perfect dinner for a November Saturday night,we dined with a side salad, nice bread and a glass of wine. Hope you are having a very pleasant evening too. Thanks for posting it.

Wendy Polisi
Yes, it is cooked in step 3.
Tonya
The flavor was great, but my quinoa was undercooked. I didn't realized until after reading the comments that it should be fully cooked after step 3. I thought putting it in the oven would finish cooking it, but it was still crunchy.
Lindsey
I have a daughter with fructose malabsorption so I would need to omit the garlic and shallots. Do you think sautéed onions would be a good substitute? Or do you have other suggestions to enhance the flavor profile?
Wendy Polisi
I think onions would be great!

I made this for a side for Thanksgiving and it was such a huge hit that I made an entire casserole just for myself this week! I added some ground chicken in to make it more of a meal for myself, and it is SO delcious. Thank you so much for this recipe <3
Laurie
Can you tell me if this freezes well?
Gwen
Is there any way to reduce the sodium on this? Wondering why it's so high.
Wendy Polisi
I think the software is assuming you are using canned broth, which can be very high in sodium. I always make homemade broth which has much less. You could also buy a low-sodium broth.
Dina
Hi, I’d like to make this For Thanksgiving but I’d like to do it the day before will it still
present well and taste as good if made the day before then heated the next day to serve?
Kelly
I am looking to do the same thing for Thanksgiving! Maybe if you just wait to bake it (step 5) for Thanksgiving day?
Wendy Polisi
Exactly! I would prep it ahead of time and wait to bake it until Thanksgiving day.
Wendy Polisi
Sorry for my late reply Dina. The kids have all been sick and then I got it. I would prep it ahead of time and wait to bake it until Thanksgiving day.
Happy Thanksgiving!
Laurie
Hi Wendy. Thank you for this appealing recipe. I was wondering if I can prepare the casserole the day before thanksgiving and whtetherbit will be just as delicious and present well.
Wendy Polisi
Yes, you can prepare it ahead of time and then bake before serving.
Maria
Loved it. I had some left over squash that I wanted to use before it went bad and this was a simple recipe that included stuff that I had in my kitchen. I bookmarked it and will definitely make it again. Hoping that half of it will freeze well.
Wendy Polisi
I am so glad that you enjoyed it! It should freeze great.
