Factors Affecting Calories in Costco Pizza

There are a few factors that impact the total calories in a Costco pizza:

1. Pizza Toppings

More toppings means more calories, especially fatty meats like pepperoni and sausage which add a lot of fat and sodium. Veggie toppings like mushrooms and peppers add fewer calories than meats. The plain cheese pizza has the fewest calories.

2. Pizza Portion Size

Costco pizzas are very large at 18 inches. The bigger the pizza, the more total calories it will contain compared to a smaller personal pizza. Cutting fewer, larger slices means more calories per slice.

3. Pizza Dough

The dough forms the crust and contributes a good amount of carbohydrates and calories. Thicker, chewier crusts will be higher in calories than thin, crispy crusts. Hand-tossed dough tends to be the most dense and highest in calories.

4. Type of Cheese

Cheese adds a lot of fat and calories to pizza. Regular mozzarella cheese provides more calories than reduced-fat cheese. And extra cheese means extra calories.

Tips for Consuming Costco Pizza

Costco pizza can easily fit into a healthy diet when consumed in moderation. Here are some tips:

  • Stick to 1-2 slices max per serving
  • Choose veggie toppings over fatty meats
  • Request light cheese or extra sauce instead of extra cheese
  • Opt for thin crust instead of thick crust
  • Eat pizza with a salad for added nutrients
  • Split pizza with friends or family to control portions
  • Take leftovers home instead of overeating more slices

Being mindful of portions and toppings is key to enjoying Costco pizza without overdoing the calories, fat, carbs, and sodium.

Healthier Pizza Options at Costco

If you’re looking for a lower calorie pizza option at Costco, consider:

1. Cheese Pizza with Veggie Toppings

Build your own veggie pizza starting with a plain cheese pizza and add all your favorite veggies like mushrooms, onions, tomatoes, spinach, etc. Skip the fatty meats to cut down on calories.

2. Single Serve Pizza

Order a single serve pizza instead of a whole extra large pizza to control portions easier. A personal pizza has fewer total calories.

3. Cauliflower Crust Pizza

Try Costco’s cauliflower crust pizza for a lower carb, lower calorie option. The vegetable-based crust cuts down on calories compared to regular flour dough.

4. Protein Pizza

Choose Costco’s high protein pizza made with a double dose of cheese and meat. It’s higher in protein and keeps you full longer.

The Bottom Line

An entire Costco pizza ranges from 2,000 – 3,000 calories depending on the toppings. The popular cheese and pepperoni pizzas both clock in around 2,800 calories for the whole thing. Supreme pizza is the highest at 3,000 calories. Veggie pizza is slightly lower around 2,500 calories.

To moderate your calorie intake, stick to 1-2 slices, choose veggie toppings, or split the pizza with others. Overall, Costco pizza can be part of a balanced diet when consumed in moderation and mindfully.
