Kirkland Signature Frozen pepperoni pizza at Costco

Costco sells their 4 pack of frozen pepperoni pizza for $13.49, and these can be found in the frozen food section of the warehouse near the other pizzas such as the gluten free pizza or the mini personal pizzas

These pizzas cost $3.37 each which is on par for what you would pay for a frozen pizza from a typical grocery store. Maybe a little less, maybe a little more depending on the quality of the frozen pizza.

Each Kirkland Signature frozen Pepperoni Pizza is made with a light flaky crust and then topped with their lightly sweetened tomato sauce made from ripe tomatoes and their secret blend of herbs and spices. 

Then it’s topped with creamy mozzarella and white cheddar cheese as well as a double layer of spicy all-pork pepperoni.

One interesting thing about these pepperoni pizzas is that there is very little marketing on the box for these. The box simply says Pepperoni Pizza Thin Crust – 100% Real Cheese and a picture of a pepperoni pizza that takes up 75% of the box. 

I guess if you have a winning product, then it will sell itself and you can keep the buzzwords to a minimum.

Costco Frozen Pizza Taste Test

Solid First Impression

This is one of the few reviews that I have done from Costco where the item actually looks like the picture on the box. Generally, what you see on the box is the very very best the product or item can be.

In this case, it’s not hard to take these Costco frozen pizzas and make them the very best they can be. I simply followed the cooking instructions and took the pepperoni pizza out when the cheese was melted and slightly golden brown. The results were very good.

A Lot of Pepperoni

The second factor that made the pizza look just like the picture on the box is the amount of pepperoni. Again, the packaging can be misleading, but in this case, you really do get that much pepperoni. 

The pepperoni on this pizza is abundant, and the pizza is literally covered with pepperoni. Many of them are even overlapping! Costco has delivered with these frozen pepperoni pizzas.

If I were to have one complaint, it would be the amount of oil that was present when I finished baking this frozen pizza. 

The pepperoni’s glistened with oil. Normally, I don’t mind a little bit of excess oil, but with these Costco pizzas, I had to take a paper towel and pat them down. 

Standard Frozen Pizza Taste

For taste, the cheese and pepperoni are about what you would expect. I thought the pepperoni was delicious. I didn’t find it spicy at all, but it was a higher quality pepperoni than most other frozen pizza companies. 

I wouldn’t be surprised if this pepperoni was actually used in pizza shops. It was good and the star of the pizza.

The cheese was more typical of that of a frozen pizza. When melted, the cheese was extremely easy to pull off and separate from the pizza – I’m not a fan of that. 

When you take a bite of this pizza, the cheese won’t stretch and pull, but instead will separate from the sauce and you could potentially pull all the cheese off your slice of pizza with one bite.

The Thin Crust Was Decent

The crust was above average, but it was still a dead giveaway that this was a frozen pizza. I didn’t find it to be a positive or a negative. It tasted less cardboard-y than other frozen pizzas, but it’s not a pizza that you share with true pizza lovers. 

The crust was thin as advertised but also bland. It was simply there to deliver the cheese and pepperoni to my mouth.

The pizza as a whole is good, not great. For $3 and change, I don’t think you can find a significantly better pizza, but you can definitely find a significantly worse pizza.


Note: For an extra flavor boost, try these with 505 Southwestern Hatch Green Chiles from Costco. It is a delicious combo that will elevate this pizza significantly.

Costco Pepperoni Pizza Heating Instructions

How to Cook Costco Frozen Pizza

The box lists only one heating method for these frozen pepperoni pizzas and that is to bake them in the oven. Oven baking the Costco pizza is going to be the best option, but you can also air fry them if you have a oven style air fryer. I will provide both cooking instructions below.

Costco Frozen Pizza Heating Instructions scaled

Costco Frozen Pepperoni Pizza Instructions - Conventional Oven

  • Preheat Conventional Oven to 425°F
  • Line baking pan with foil and spray with cooking oil. 
  • Place pizza on pan and place pan directly on center rack in the center position.
  • Bake for 12 to 15 minutes, or until crust is brown and cheese is melted and golden brown. 

Of course, all ovens will vary slightly. After 12-15 minutes, rely on appearance to determine if the pizza is done. You should be looking for the crust to be brown and the cheese to be melted

Costco Pepperoni Pizza Convection Oven Instructions

These are not official cooking instructions for this Costco frozen pizza, but they should work just fine and cook the pizza a little quicker. The pizza may also develop a more toasted and delicious crust. 

  • Preheat Convection Oven to 425°F
  • Line baking pan with foil and spray with cooking oil. 
  • Place frozen pepperoni pizza on pan and place pan directly on center rack in the center position.
  • Bake for 11 to 14 minutes, or until crust is brown and cheese is melted and golden brown. 

Again, ovens will vary, so determine doneness of the pizza by appearance. 

Costco Frozen Pizza Air Fryer Instructions

The Air Fryer will be my favorite way to heat these Costco frozen pizzas. It will be extremely fast, and the food will be hot and crispy. 

  • Preheat Air Fryer to 400°F
  • Place frozen pepperoni pizza in the air fryer 
  • Heat for 8-11 minutes or until cheese and crust are both golden brown. 
This shouldn’t have to be said, but no need to shake the pizza or flip the pizza when its in the air fryer.

I personally will eat a minimum of 3 servings (3 quarters of a pizza) of this Costco frozen pizza, and I would say that the recommended one quarter of a pizza is on the smaller end.

It is a frozen pizza, so the nutritional information isn’t too surprising. This isn’t meant to be a healthy food to eat, instead it’s a quick and delicious snack or meal. The sodium is astronomically high so eat in moderation and stay hydrated with your favorite sparkling water.

Extremely High Sodium!

Like most frozen foods, the sodium is going to be high. For one serving, there is 990 mg of sodium which is 43% of the Daily Value. This is an extremely high amount for only one-quarter of a pizza.

I ate the entire Costco frozen pizza and I consumed almost 4000 mg of sodium and nearly 175% of my recommended daily value. Whoopsies.

Final Thoughts

Overall, this frozen pizza from Costco is above average. It’s a very fair price of $3.37 per pizza, but I wouldn’t pay much more than that. Personally, I purchase this 4 pack of Costco pizza, maybe 3-4 times a year. 

It’s a great product to have on hand in case of a dinner emergency. It’s not a replacement for a delivery pizza, but for a quick and easy weeknight meal, it gets the job done.

  1. We buy this all the time, we find 400 degrees for 15 min is just fine. One tip is as soon as the pie comes out of the oven sprinkle with garlic powder and Italian seasoning, take it to the next level. Making me hungry, may just go take one from the freezer and heat it up for lunch.
