Sweet Potato Quinoa Casserole

Thanksgiving is coming up and I have the perfect side dish for you!  This sweet potato quinoa casserole is packed full of cauliflower, minced garlic, roasted sweet potatoes, spinach, and 3 kinds of cheese, guaranteeing it to win the hearts of anyone who tries it.


The star ingredient in this recipe is Honeyville organic quinoa (pronounced keen-wa). Quinoa is one nutritious and versatile little seed.  It’s so easy to add to recipes.  From muffins and salads, to breakfast porridge, and every type of main dish in-between quinoa adds a healthy and filling flare.  Benefits of quinoa include:

  • It’s a complete protein meaning it has all 9 essential amino acids.
  • Quinoa contains almost twice as much fiber as most other grains.
  • It’s rich in important minerals like iron and magnesium.
  • It contains a lot of antioxidants such as manganese and flavonoids.
  • Quinoa is gluten-free.

Did I mention that quinoa cooks in only 15 minutes?  Not only that, but it lasts a full week in the fridge.  It’s the perfect ingredient to add to your weeknight dinner menu or toss in your lunch.


If you’re looking for canned cream of something soup, look no further than a casserole. Simply because that is the nature of casseroles. The beauty of this one is that all the saturated fats and food colorings are left out by substituting the canned soup for nonfat greek yogurt, while preserving the perfect mild, creamy texture casseroles are loved for.

Creamy creamy, yum yum. Nothing from a can. Everyone is happy!


Casseroles are definitely a great way to feed your gluten free family and friends without missing out on any flavor, and this Sweet Potato Quinoa Casserole is sure to pass all expectations! Bottom line: if you’re looking for a healthy comfort food casserole made from scratch (no cream of anything soup), this baked goodness recipe is just for you!
