This Spinach Mushroom Cheesy Rice Casserole is perfect as a side or could easily be the main course. Β Of course it’s filled with spinach, mushrooms, cheese and Β rice for a family friendly meal. Vegetarian and Gluten Free.
So with Thanksgiving less than a week away I thought I’d share one more of my favorites dishes.
This Spinach Mushroom Cheesy Rice casserole could easily be a great side to add to your Thanksgiving table.
The best part is that you can make several days in advance. Hence allowing you more time to spend with family and friends.
And after all it really is meant to be a relaxing day π
As much as I do enjoy eating all the yummy food, I really just appreciate a break from the normal routine.
While I’m very much Thankful for being able to purse one of my passions<—creating new recipes and sharing them…It’s still nice to take a little break from it all and Enjoy the moment.
So over the next few days I plan on preparing my dishes ahead and on Thanksgiving day just allowing myself the change of routine…You know sleeping in a little late, eating a little extra, just doing nothing at all..
Ahhh,Β I really think I am ready. How about you guys? What are your family traditions?
Whether it be hanging out watching football games, getting an early start on Christmas shopping or just enjoying the extra long weekend. Or maybe even a little bit of all of that.
I know most of us can find plenty of things to be THANKFUL for but mostly Β just enjoy taking care of you. The number one thing I strongly believe..you have to take care of yourself in order to give back to others.

I love spinach and mushrooms together, and anything with “cheesy” in the title sounds great to me!

You’re welcome Luci! It really does make great leftovers π
Doing all of the prep ahead of time is such a good idea! I always plan on doing that, but somehow still have to run around like a chicken with its head cut off on Thanksgiving day. π This casserole sounds like the perfect addition to a Thanksgiving feast!
Thanks Elizabeth! Hope you have a great Thanksgiving π
OMG I can totally relate – when you’re a food blogger, you seriously need to make things ahead of time to enjoy the actual day of the event! So glad you are preparing to take a little time off! This casserole looks like the perfect vegetarian side for the Thanksgiving table π
Thanks Taylor! I definitely am ready for a little break π
Three of my favorite things in there.. Rice, Mushrooms and Chees!! Can’t go wrong.
Thanks
You’re welcome! Mine too π
Spinach and cheese — I’m in heaven. This is a great sounding recipe. Great way to get the little ones to eat their greens.
Thanks Marisa and yes it is…
Never made a mushroom and rice casserole before but love the sound of it! Will try to make this dairy free with some dairy free cheese!
Thanks! I’m sure you could easily make it with that π
I love “one dish” type dinners that have veggies baked right in. Spinach and mushrooms? Yes please!
Thanks Julie! They’re my favorite too.
Such a great dish! Love the spinach and mushroom combination!
Thanks Mira !
Cheeeeseeee!!!! Anything cheesy is my kind a food π Looks de-li-cious! Happy Thanksgiving Stephanie π
Thanks Natalie! Me too…I’m all about the cheese. Hope you’ve had a good one also and enjoy the rest of your weekend π
Hii.. Loved the recipe… But can u give another option for mushrooms and eggs… I don’t eat these..
Hi Sonia, you could actually just leave out the mushrooms if you like and maybe try adding some extra spinach and cheese. You could probably try replacing the eggs with flax eggs. Let me know if this helps and how it works for you π
