Butternut Squash Quinoa Casserole Will Become a Go-To Favorite!

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.

How to Make Vegetarian Butternut Squash and Quinoa Casserole

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

Can You Make This Dish Ahead of Time?

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.

Can You Freeze It?

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.

How do you store butternut squash?

Butternut squash can safely be stored at room temperature in a dark space for up to a month.

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.

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 1/4 cup melted butter, 1/4 cup brown sugar, 1/2 cup toasted pecans, 1/2 cup oats and 1/4 cup flour. Sprinkle on top of the casserole before baking.
• Saute 6 ounces chopped mushrooms and add to the mixture prior to baking.

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 1/4 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.
