I love this quinoa casserole because it is quick. If you are trying to eat less meat this spinach artichoke casserole recipe is for you. It is hearty, filling, and full of flavours. I used an entire box of pre-washed baby spinach. I truly love the convenience of washed organic greens. Spinach shrinks a lot, so don’t be scared by the amount this recipe calls for.

I’ve been trying to experiment with more meat-free recipes recently, to add more to my list for when vegetarian guests visit. Recently I made an Instant Pot vegetarian chili, pasta with zucchini and tomatoes, cauliflower rice risotto, and a roasted red pepper lasagna! I think I’m starting to get the hang of this!

And please don’t judge my pot. It is my favourite Lagostina pot which outside goes bonanza in a dishwasher. And who can give up a dishwasher?!

Enjoy this delicious spinach artichoke quinoa casserole as much as we did! If you enjoy spinach and artichokes together, try hot spinach artichoke dip! If you want more hearty quinoa meals you might also like my healthy chicken pot pie casserole and ground turkey quinoa casserole.

  1. I have read these instructions 3or 4 times. Ingredients says 2 cups of water directions say nothing about 2cups of water. What am I missing

  2. 2 stars
    Delicious ingredients but came out sooooo bland. Any ideas what would make this more palatable. Sadly, I would only rate it 2 out of 5.

    1. I am not sure. More cheese and garlic? Maybe that will help. This one has good reviews so people like it and we liked it when I posted it back then. Everyone has different taste buds though.

    1. Yes, Freeze: Assemble, tightly wrap with plastic and then foil, and freeze for up to 3 months. Thaw in the fridge overnight and bake as per instructions + 15 minutes.

  3. 4 stars
    I liked this recipe as a base. I added in a full bag (12oz?) of riced cauliflower, some cremini mushrooms & chopped green bell pepper, which I sautéed in with the onion. Based on other reviews, it sounded like this needed more spice so I added in dried thyme & basil as well as black pepper and crushed red pepper. Next time I’ll cook the quinoa in a mix of water/veggie broth for more flavor.
