Is it just me, or is anything smothered in cheese pretty much perfect? You know I am all for healthy, clean meals that are delicious, but sometimes your love for cheese wins a bit, am I right? Not to worry, you can have your pizza and eat it too without any guilt because this pizza casserole is filled with delicious creamy cauliflower, pizza sauce, meaty mushrooms and topped with melty bubbly cheese.

Dinner, anyone?

This casserole came together pretty easy, and for anyone wondering about the cauliflower taste, cauliflower is one of my favourite meat substitutes. Being vegetarian doesn’t mean you don’t want something hearty to eat, and vegetables like cauliflower are perfect for that. It gets soft and creamy but maintains a texture that makes this casserole not only delicious, but very filling. Even better, the addition of mushrooms takes it over the top leaving you with a casserole that could easily replace Friday night pizza once in a while.

While I thought this tasted delicious fresh, reheated it seemed that the flavours melded together even better and tastes so great – kind of like leftover pizza that’s heated back up. While it seemed pretty easier to cream the cauliflower, I really wanted the vegetable to shine through, and it really does in this dish. I honestly think this is a great dish to get someone who is on the edge about cauliflower over on the right side! Okay, so I’m totally a cauliflower cheerleading, but you will definitely love this dish! And let’s not forget, melty, bubbly, golden brown cheese.

Need I say more?

    This looks great Jessica!

  2. Yum! I will have to give this one a try! Cauliflower is one of my favorite veggies!

  3. I too love cheese flavours! Your casserole looks satisfying and packed with flavours. Totally right up my alley.

  4. This is totally weird…the comment above (I too love cheese flavours! Your casserole looks satisfying and packed with flavours. Totally right up my alley.) was from me. But the profile is from Manali@CookWithManali…no idea what happened…

      Hey Angie,

      I have no idea what’s going on – I just got an email from another reader letting me know so we’re going to try and fix it now. So sorry about that, and I’ll fix the comment also.

    This is a delicious dish that I have been making and playing with for several years now! I like the veggies in mine, but the guys in the house like meats added to theirs. I usually have homemade marinara sauce in the freezer and we have a design your own pizza night. The grandkids love to participate in the fun of making their own!! I cut up/prepare all the ingredients they get to pick from ahead of time and away we go!! Great memories are created!!

    • Jessica says:

      Thanks sound great Michelle! I love dishes that create memories. Thanks for commenting!

  6. Jackie says:

    I’m with all the above. It looks wonderful and I can hardly wait to make it tomorrow. It’s a great way to get my husband to eat more vegetables. Thank you….

  7. Kelsey says:

    This looks mouth wateringly good! I’ll definitally be making it on one of my dinner nights very soon. I think I’d also like to mix up extra large batches of the “filling” for even quicker meals, if it would freeze well.

    • Jessica says:

      Hi Kelsey,

      Thank you! I hope you enjoy it when you try! I haven’t tried freezing it but if you put it in a freezer safe container it should freeze well!

  8. Renae says:

    Yummy!! I can’t wait to give this recipe a try, it looks so good!!

  9. Ann M says:

    I made this tonight and it was fantastic!

    I tried to pin this 6x but no success. The error message is partially covered by your photo (no matter which pic I use)?! Sure wish I could pin it, this looks good and I hope to try it. Thanks.

    • Jessica says:

      Hey Wendy,

      So sorry about that. What error message are you referring to? I don’t see any on my end.

      • Wendy says:

        Hi and thanks for quick response! Error said unable to save?!
        I ended up adding the Firefox Pin It button so maybe now it will work. Funny, cuz I was always able to ‘pin’ without it before. I can’t wait to try your recipe! yum!
