Sometimes you want an easy dinner without a lot of fuss — and frozen pizza fits the bill. If you’re looking for a lighter option, cauliflower-based frozen pizzas are an appealing alternative to traditional flour crusts.
Costco’s cauliflower pizzas have become popular for shoppers seeking a gluten-free or lower-carb option. These pizzas use a crust made from cauliflower combined with rice flour and mozzarella cheese, delivering a crisp texture and satisfying flavor. Because the crust contains less refined flour, it can be a good choice for people reducing carbs, though it’s not automatically healthier in every respect.
We sampled both cauliflower pizza varieties sold at Costco to answer the most common questions: Do they taste good? Can you detect the cauliflower? Are they a healthy choice? Below you’ll find our findings on ingredients, nutrition, baking instructions, price, and an overall review to help you decide if one belongs in your freezer.

Does Costco Sell Cauliflower Pizza?
Yes. Costco typically carries two frozen cauliflower pizza options: the Kirkland Signature Supreme Cauliflower Crust Pizza and Milton’s Craft Baker Cauliflower Crust Roasted Vegetable Pizza. You’ll find both in the store’s freezer section.
The Kirkland Signature Supreme includes meat toppings such as pepperoni and sausage, while Milton’s focuses on roasted vegetables. Both are marketed as gluten-free alternatives to traditional pizzas.
Prices vary by region and time of year, but in our check the Kirkland pack was less expensive per pizza, while Milton’s sometimes appears at a slightly higher price point. Sales and local pricing can affect the final cost, so look for the current product tag when shopping.
Costco Cauliflower Pizza Baking Instructions & Cooking Time
Both cauliflower pizzas are baked directly from frozen and yield the best texture when placed directly on the oven rack. Do not defrost before cooking.
Milton’s Cauliflower Pizza:
- Preheat oven to 425°F (220°C).
- Remove plastic wrap and cardboard; place pizza directly on the oven rack.
- Bake 12–15 minutes or until the internal temperature reaches 165°F (74°C).
- Let rest 2–3 minutes before slicing and serving.
Kirkland Signature Cauliflower Supreme Crust Pizza:
- Preheat oven to 425°F (220°C).
- Remove plastic wrap and cardboard; place pizza directly on the oven rack.
- Bake 17–19 minutes or until hot throughout (follow package guidance for safe temperature).
- Let rest 2–3 minutes before serving.
Is Costco Cauliflower Pizza Healthy?
Cauliflower crusts typically offer more fiber and fewer refined carbohydrates than conventional wheat crusts, but “healthier” depends on what you compare. These Costco cauliflower pizzas can still be higher in fat and cholesterol due to cheese and toppings. Both versions are labeled gluten-free, which is helpful for people with gluten sensitivities, but they are not inherently low-calorie or low-fat.
Costco Cauliflower Pizza Nutrition
Calories and Serving Size
A single serving (one-quarter of the pizza) differs between brands. The Kirkland Signature Supreme registers higher in calories per quarter slice compared with Milton’s roasted vegetable version, largely due to the meat and extra cheese on the Kirkland pie.
Most adults will eat two to three slices in a sitting. For reference, a full Kirkland cauliflower pizza contains substantially more calories than the Milton’s version because of the additional toppings.
Costco Cauliflower Pizza Ingredients
Milton’s Roasted Vegetable Cauliflower Pizza ingredients include a cauliflower crust made with cauliflower, low-moisture mozzarella, rice flour, tapioca starch, egg whites, and seasonings. The toppings list tomato sauce, roasted zucchini, roasted bell peppers, roasted onion, Pecorino Romano and Parmesan blends, roasted garlic, basil, and oregano. Ingredients are subject to change, so check the package if you have allergies or strict dietary needs.
Is Costco Cauliflower Pizza Keto Friendly?
Not necessarily. Removing white flour reduces carbs, but these pizzas still contain a moderate amount of carbohydrates. Milton’s cauliflower pizza, for example, lists about 19 grams of net carbs per quarter pizza, while Kirkland’s Supreme lists around 24 grams of net carbs per quarter. The Kirkland version has a bit more protein thanks to the meat toppings, but neither pizza is strictly keto-friendly for most people following a strict ketogenic diet.
Does Costco Cauliflower Pizza Have Carbs
Yes. Both brands contain carbohydrates. Typical nutrition labels show total carbs and fiber amounts that result in net carb counts in the high teens to mid-20s per quarter pizza. These figures are somewhat higher than some competing cauliflower crust brands, so compare labels if low-carb is your priority.
| Milton’s | Kirkland Signature Supreme | |
| Total Carbs | 27g | 31g |
| Dietary Fiber | 2g | 1g |
| Total Sugars | 5g | 4g |
| Added Sugars | 1g | 2g |
Costco Cauliflower Pizza Price
Prices change by store and season, but typically the Kirkland Signature two-pack has been priced lower per pizza than Milton’s two-pack. Sale events occasionally drop Milton’s price to a very attractive level. Compared to many grocery-store cauliflower pizzas, Costco offerings are competitively priced and often represent solid value for the freezer.
These Costco options usually cost less per pizza than some national brands, which can make them a convenient, budget-friendly way to stock your freezer without sacrificing texture or flavor.
Costco Cauliflower Pizza Review
Our pick: Milton’s Roasted Vegetable Cauliflower Pizza — flavorful, balanced, and worth the slightly higher cost.
Both cauliflower pizzas surprised us in a good way. They crisp up well and don’t taste overly “vegetable-y”; the cauliflower provides structure and crunch without a strong cauliflower flavor. Kirkland’s Supreme is heartier thanks to pepperoni and sausage, but it can be greasier and tends to brown more at the edges than the center.
Milton’s roasted vegetable option offered a lighter, more balanced bite. The vegetable toppings were plentiful and tasty, though some textures — like frozen mushrooms — can become a bit soft after baking. Overall, Milton’s delivered the better eating experience in our test and was a hit even with kids.
For families and shoppers looking for a quick, freezer-stable pizza that is lower in refined carbs and gluten-free, Costco’s cauliflower pizzas are worth trying. They offer crisp crusts, solid flavor, and good value compared with retail single-pizza options.
