Cauliflower pizza offers a few nutritional advantages for people who are health-conscious or have dietary restrictions.

After trying this Costco Kirkland Signature Deluxe Cauliflower Pizza, I can honestly say the answer is yes! Whether you’re gluten-free, following a low-carb lifestyle or just looking to incorporate more vegetables into your diet, you’re going to want to read this review!

Pizza is probably our all-time favorite food and I’m always up for trying a new frozen pizza from Costco. On my last Costco trip, I saw this new Kirkland Signature Deluxe Cauliflower Pizza and immediately wanted to try it. Usually, the Kirkland brand delivers some pretty tasty food, so they probably make a half-decent cauliflower crust.

The seasoned sausage is really delicious and I like that there’s zucchini.

Other frozen pizzas from Costco I’ve tried are the Motor City Pizza Co. Double Pepperoni Pizza, Pizza Roncadin Chicken & Grilled Peppers Pizza, Kirkland Signature Pepperoni Pizza, Sabatasso’s Gluten Free Four Cheese Pizza, Kirkland Signature Cheese Pizza, Sabatasso’s Pizza Singles and the Molinaro’s Napolitano Pizza Kit.

This can be found in the freezer aisle at Costco, near all the other frozen pizzas. The item number is 1630821.

I’ll get right to the point: this is a good frozen pizza. If I didn’t know better, I might have just thought it had a thin crust. Otherwise, it compares favorably to Costco’s other frozen pizzas. It’s tasty and loaded with toppings.

The crust really doesn’t stand out, and I think that’s a good thing. Taking a piece of the crust by itself from the edge and really focusing on the flavor, I notice a hint of cauliflower, but I have to really look for it. The crust is crisp around the edges and softer (though still slightly crisp) in the middle. Overall, it’s very enjoyable.

As I mentioned, the pizza is loaded with plenty of cheese, meat and veggies and they’re all tasty. Both the meat and the sauce are a little bit spicy, but probably not enough to turn anyone off.


The box comes with two individually wrapped 550-gram frozen pizzas and costs $16.99 Canadian which is kind of expensive because the pizzas are pretty thin and not that big. You’re definitely paying extra for the cauliflower crust.

There are two pizzas in the box.


I baked it in the oven directly on the rack for the full 18 minutes at 400 degrees Fahrenheit. I was glad I put a baking tray underneath on the lower rack as the pizza did drip. The pizza needs to be kept frozen and the best-before date is five months from the date it was purchased.

I think this is a good option for anyone who’s allergic to gluten or following a gluten-free diet. I don’t think any wheat eaters would be disappointed by having this pizza over a regular-crust pizza either.

One-third of one deluxe pizza contains 420 calories, 20 grams of fat, 40 grams of carbohydrates, three grams of fibre, five grams of sugar, 20 grams of protein and 1070 milligrams of sodium. That’s quite a lot of sodium!

Although a third of a pizza may seem like a lot it’s actually not that much due to the thin crust. Although it’s a cauliflower crust pizza it’s not low-carb but it’s nice that it does have a decent amount of protein in it.

There’s a very long ingredient list for the pizza but all the ingredients listed are ones I’d expect to see. I think they make the cauliflower crust taste good by adding a bunch of mozzarella to it. There’s egg and milk in the pizza and it may contain mustard and soy.

Must buy!

This pizza was a pleasant surprise. Frozen pizza is never the same as restaurant pizza, but this is a very good frozen pizza.

  1. Actually very delicious and my “go to” pizza delight. Sodium is a bit higher than I like BUT I have a beer with my meal and it’s just fine.

  2. My husband and I were SHOCKED at how delicious this pizza is! I have tried several cauliflower pizzas, and usually at least somewhat disappointed. The crust on this Kirkland pizza is so firm and crispy….just couldn’t believe I was eating a cauliflower crust. Even better than the cauliflower crust I’ve had at restaurants! I will buy this again and again. I only wish they made it in cheese and/or pepperoni. I have grandkids that I could easily slide this into their meals and they would never think they were eating healthy, but they won’t do the supreme. Thanks!

    • In my Costco there is a vegetarian pizza right next to it. It’s not Kirkland Signature brand, but I’ve tried it and am convinced it is the same pizza without the meat toppings. Regular price is $2/USD more than the Kirkland, but it is discounted somewhat regularly.

  3. I was simply looking for the cooking instructions after misplacing the box. Wonderful review! And the pictures of the box gave me all the info I could have wanted and more.

    “The crust really doesn’t stand out, and I think that’s a good thing.” My exact thought and nearly my exact quote after sampling it and bringing it home. (Have some gluten intolerants in the house)

  4. We just had it for the first time in Florida and it was absolutely delicious. I couldn’t believe how good it was and we love wonderful pizza since were from New England I’m shocked that it was so delicious price here was $11.99
    When we usually spend $40-$45 on a pie, this is a great savings we will definitely Stock up ! Thanks Kelly Dodd for turning us on to this great pizza

  5. The is the best frozen pizza I’ve had! I have a gluten allergy and was very excited to find this Kirkland product – way better than gluten free delivery pizza which is more expensive and sometimes inedible!

  6. This pizza sweet… and very salty. Anyone who passed the ‘taste’ test for this pizza, must be addicted to sugar. It was very strange eating this… my taste buds were confused, was I eating desert or a pizza?! This could have been great, but alas it was created by a sweet-addicted individual whose taste buds were numbed out by all that high fructose corn syrup. People, get off that sugar rush!

    • Omg, Totally agree! It’s not bad but I kept thinking.. why is this pizza sweet?
      If people stopped eating sugar for two weeks, their taste buds would reset and then would be able to taste how much added sugar there is to Everything!

  7. First had this in Florida. Loved it!

    It is expensive but it is a good, tasty pizza.

    Glad they now sell it in Canada!

  8. I saw some great reviews of the Kirkland Signature Deluxe Cauliflower Crust pizza. Bought a package of 2 and cooked one for lunch today. It was unbelievably salty!!!! I love cauliflower crust pizza so assumed that I would also love this one. The remainder of the pie went in the trash right away. The other pizza is in my freezer for now. Maybe if I try it another time it won’t seem so bad???

  9. I find the Stellareats brand as a superior pizza crust option.

  10. The carbs sugar for one third of a pizza along with the list of ingredients starches natural flavors and other additives..string pass in this..unless you are gluten intolerant have a slice of real pizza and enjoy it or download any one of hundreds of cauliflower pizza from the internet.. Be well.

  11. Perhaps if you are gluten intolerant . But otherwise, why? Why frozen? Convenience? Occasionally, I guess.

    Whatever happened to preparing ones own food and having some control over the ingredients list. Using fresher food, not frozen. Learning how to make a great pizza is a good skill to have on it’s own. Make it with your kids and teach this skill to them.

  12. Just too expensive. Of course it would be nice if Costco put it in one of their sales but they don’t seem to do that with Kirkland Signature stuff very much.
