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.

Notes

Tips for Making Quinoa and Sweet Potato Casserole

To make a vegan quinoa casserole, omit the eggs and use unsweetened almond milk and vegan cheese.

Variations for Sweet Potato Quinoa Casserole

For a more hearty meal, stir in 16 ounces of cooked shredded chicken prior to baking.
For additional vegetarian protein, add in 1 ½ cups (one can) of cooked, drained and rinsed black beans before baking.
Add 10 ounces of sautéed baby Bella mushrooms and 1 ½ cups cooked, drained and rinsed cannelloni beans prior to serving.
For a sweet twist, omit the cheese topping. Instead, meant ¼ cup butter in a small saucepan. Whisk in ¼ cup brown sugar until well combined.
