Costco Pizza Calories Complete Guide: All Slice Counts

Description

Costco Pizza Nutrition Facts: Calories Per Slice (2026 Data) — a dietitian-informed calorie and macro breakdown of all three Costco food court pizza varieties, perfect for health-conscious eaters and meal trackers. Covers 3 slices in 10 minutes of reading with zero prep.

Ingredients

Scale

1 slice Costco Cheese Pizza (pre-cooked, 1/8 of an 18″ pizza)
1 slice Costco Pepperoni Pizza (pre-cooked, 1/8 of an 18″ pizza)
1 slice Costco Combo Pizza (pre-cooked, 1/8 of an 18″ pizza, where available)

Instructions

Select your Costco pizza variety—cheese, beef pepperoni, or combo—based on your daily calorie and sodium targets before ordering at the food court.
Review the per-slice macronutrient breakdown below, noting that combo offers the lowest calorie count at 680 kcal per slice.
If reheating a leftover slice, preheat your oven or air fryer to 375°F and allow 5 minutes to reach full temperature.
Place the slice directly on the oven rack or air-fryer basket and reheat for 8 minutes until the cheese bubbles evenly.
Blot the surface with a folded paper towel for 30 seconds before eating to remove up to 40 calories of excess surface oil.

Notes

Fridge: Wrap leftover slices individually in aluminum foil or place them in airtight containers with parchment paper between layers to prevent sticking. Store on a middle refrigerator shelf at or below 40°F. They’ll stay safe and flavorful for up to 3 days. Avoid the door shelf where temperature fluctuates with frequent opening.
Freezer: Wrap each slice tightly in plastic wrap followed by a layer of foil, then place inside a freezer-safe zip bag with excess air pressed out. Label with the date and pizza variety. Properly wrapped slices maintain quality for up to 2 months. Thaw overnight in the fridge before reheating for best results.
Oven Reheat: Preheat your oven to 375°F. Place the slice directly on the oven rack or a baking sheet lined with parchment paper. Heat for 8 minutes until the cheese is bubbly and the crust feels crisp on the bottom. This method best restores the original food court texture and avoids sogginess.
Microwave Reheat: Place the slice on a microwave-safe plate with a small cup of water beside it to add steam and prevent rubbery cheese. Heat on medium power for 90 seconds. The water trick keeps the crust from becoming tough. Eat immediately—microwaved pizza loses quality rapidly as it cools down.
Air Fryer Reheat: Preheat your air fryer to 350°F. Place the slice in the basket without overlapping and heat for 4 minutes. The circulating hot air crisps the crust beautifully while melting the cheese evenly. This is the fastest method that still delivers oven-quality crispness and is ideal for single-slice reheating.
