How is the sauce so creamy and dairy free?

We looovveee making dairy free sauces that feel just as indulgent and rich, but without the dairy. The creamy sauce in this spinach artichoke chicken casserole is made with mayo as the base. We used nutritional yeast to add some cheesy, umami flavor. The sauce is actually a recipe we made for a spinach artichoke dip a while back!

It’s versatile and great for entertaining or taking to get togethers. It always gets eaten up real quick, and nobody has any idea it’s dairy free and healthier. Here are our preferred mayo options.

What is nutritional yeast and is it necessary?

There’s no need to be scared of yeast in the name. Nutritional yeast is an inactive yeast, meaning that it doesn’t cause an issue for people with yeast overgrowth or candida issues. We love it because it adds a cheesy, umami flavor to whatever you’re making, which is great for dairy-free recipes like this spinach artichoke chicken casserole!
