One Pot Supreme Pizza Quinoa Casserole is a great way to get your pizza fix, but in a healthier and more wholesome way. You’ll love how easy and how quick this one pot meal is to make!

To start the year off, even though January is nearly over, which is crazy, I’m sharing an easy one pot dinner. One pot supreme pizza quinoa casserole is perfect for that pizza craving, when you want something a little less greasy and a little more wholesome.

My alternative is to make healthier “imposter” versions of the foods I love and to make them as quick and easy as possible to get on the table. The faster they’re on the table and in my mouth, the less time I have to think about picking up the phone and ordering that pizza.

What’s great about this pizza version is you can customize the toppings to what you and your family like. I chose to use Italian turkey sausage, bell pepper, red onion and black olives. Not a fan of olives? Use mushrooms instead. Want to make it vegetarian? Just omit the sausage.

Forget dialing your favorite pizza place this week and try making this healthier and far more filling One Pot Supreme Pizza Casserole instead!

This was so good and so easy! Will become a go to recipe for sure! Was a hit with my family! It truly does taste as though you are eating pizza! 🥰
In the instructions where its says to add basil, oregano, etc it mentions garlic powder but garlic powder is not on the ingredients list. Do I add garlic powder in with the other herbs? If do, how much?
Yes, you can add 1/4 teaspoon of garlic powder with the other spices. Enjoy!
We’re a vegetarian household, so I substituted Field Roast Italian sausage. I doubled the recipe but kept everything else the same. I was worried that there wasn’t enough liquid, but it was! I had to cook it for 30 minutes to absorb all of the liquid. It was fantastic! I plan on making it again. Thanks!
So glad that you were able to adapt the recipe to fit your needs. Thanks so much for sharing your feedback!
I’m eating this right now and it is delicious. Super straight forward. Great instructions. Thanks!
