The meat prices at my favorite supermarket are outrageous; another unfortunate side effect of the virus. 😞 Given the high price tags we’ve been consuming less meat in my household. Truth be told we often skip it anyhow, so it hasn’t been all that hard.

But who needs it anyway when you have delicious options like this spinach artichoke casserole?!? For real, it’s so good you’ll forget all about the meat.

This casserole is packed full of nutritious seasonal veggies like spinach and artichokes. And rather than straight-up rice, I went with cauliflower rice. If you haven’t tried cauliflower rice, YOU SHOULD!!!

Aside from the obvious nutritional value, it’s also low carb, low calorie, and gluten-free. Yay!!

Ok, now that I’ve hyped you up with all this talk of healthy produce, let me bring you back down a notch on the good-for-you scale.

In true spinach and artichoke fashion, as in spinach and artichoke dip, this casserole has cheese. It just has to. It’s truly a combo made in food heaven.

Plus what’s a casserole without it? Not good, that’s what. The addition of cream cheese makes this dish super….uh, what’s the word??? CREAMY!!!

Topping it all off is some parmesan cheese which is melted and browned to golden perfection under the broiler. Crispy top and creamy oh so dreamy 😍 under the surface. Just how I like it.

If all that isn’t enticing enough, let me add that this dish can be prepared and plated in less than 30 minutes in one cast-iron skillet. You heard me right, just one!! This dish is a quick and easy, healthy(ish) gluten-free vegetarian one-pan meal.


Ingredients (+ notes & substitutions)


Ingredients for Cauliflower Rice Spinach Artichoke Casserole (see recipe card).
  • Butter: Could sub for olive oil.
  • Fresh spinach: You could sub for four ounces of frozen spinach. Make sure to fully thaw it and squeeze out any excess liquid.
  • Canned artichoke hearts: For this recipe the artichokes should not be marinated.
  • White onion: Yellow would also work.
  • Garlic
  • Cauliflower rice: One medium head of cauliflower should yield enough. To rice the cauliflower simply run it through a food processor fit with a shredding disc. You could use pre-riced cauliflower,found in the freezer section, but it will need to be fully thawed prior to use.
  • Vegetable broth: Chicken broth would be suitable as well but not advised if you wish to keep this dish vegetarian.
  • Lemon juice: To bring balance and brighten the dish.
  • Kosher salt
  • Ground black pepper
  • Cayenne pepper: Because everything’s better with a little heat, right??? Should you disagree, leave it out! No biggie.
  • Ground sage
  • Ground nutmeg: Feel free to omit.
  • Cream cheese: Although not entirely necessary, it melts and incorporated easier if it is softened first.
  • Shredded Parmesan: Do yourself a favor and skip the bottled stuff. Keep in mind that real Parmesan cheese is not vegetarian-friendly. If you would like this casserole to be vegetarian, I suggest swapping the Parmesan for mozzarella.

I made this once before but it came out soupy. This time I decreased the broth to 1/2 cup and it is just like the restaurant spinach artichoke dip.

So sorry that happened to you the first time around. Did you use frozen cauliflower rice by chance?
