    This Sweet Potato Quinoa Casserole is the perfect one dish meal!   It works equally well for an easy weeknight meal as it does as a healthy dish for entertaining.  Gluten Free and Vegetarian, this quinoa casserole can easily be made vegan.

    I can remember when I was in grade school my Mom telling me that sometimes it is the simple things that are the best.

    As a child, I thought that this was one of those lines that parents said to their kids because they thought it was the right thing to say.

    As an adult, I’ve come to realize how much truth this statement holds.

    Our lives are all so busy, especially during this time of year. Despite the elaborate meals and fancy parties associated with the holidays, my favorite moments are almost always simple meals at home with family.

    There is nothing like these times to remind us all what matters in life.

    For me, casseroles represent the very best in stress-free cooking. I love that I can make them early in the day and all I have to do it pull it out of the fridge and cook it.

    This leaves me to spend quality time with the family, and also keeps evening clean-up to a minimum.

    I love playing with family favorites and today I’ve done just that. This Sweet Potato Quinoa Casserole is a riff on my favorite Butternut Squash Casserole. This dish originated from something I started making in my early 20’s. The original recipe was made with white rice and lots of heavy cream.

    I’ve grown to love this version even more.

    Since one of my boys won’t touch squash but loves sweet potatoes (which makes no sense to me), I decided to change up the flavor profile a bit and create something the whole family would enjoy.

    I will have to say that this is my new favorite quinoa casserole recipe.

    It is pure comfort food that you can feel good about serving!

    Frequently Asked Questions for Making a Quinoa Casserole:

    Can Quinoa Casserole Be Frozen?

    Yes! Quinoa freezes beautifully! To freeze, allow the casserole to cool completely. Wrap tightly in plastic wrap and then cover in foil. Generally speaking, quinoa casseroles may be frozen for up to three months. It is best to thaw in the refrigerator prior to reheating.

      I'm a type 1 diabetic, can I substitute home made green tea with lemon that has no added sugar for the lipton tea in the recipe.

        Hi Susan! There is no tea in the recipe so you should be good to go with this one.

      I have made this 4 or 5 times, and it is an amazing dish. I use white, orange and purple sweet potatoes mixed together and have added some spinach right before baking when the mixture is sitting for 5 minutes in the pan. I also tried Manchego cheese for something different, and it was delicious. It is a versatile recipe that lets you add some other healthy foods and is great for leftovers at lunch.

      This is one of my favorite recipes. I hadn’t made it in a while and had all the ingredients today! I tried something different-I added the sweet potatoes to the quinoa after the quinoa finished cooking. I found that the sweet potatoes stayed nice and bright orange and firm. It’s such a versatile recipe and soooo healthy. I will keep enjoying it.

      Mixed in spinach and mushrooms while the mixture was simmering, omitted the milk and cheese to make it dairy free (just added a tablespoon or so of water to the eggs and poured on top before baking) and added sliced avocado to the top when done. 100% recommend. One of the best dinners I've had in a while.
