4 min read

Weighing in at approximately 4 to 4.5 pounds, the Costco chicken alfredo is a popular and convenient deli meal that can easily feed a crowd. However, the exact number of servings can vary based on the specific tray size, individual appetites, and how it is served.

Quick Summary

The large, ready-to-bake deli tray of Costco's chicken alfredo typically yields 6 to 8 modest servings, though this is influenced by appetites and side dishes.

Key Points

Average Servings: A standard 4 to 4.5-pound deli tray of Costco chicken alfredo yields approximately 6 to 8 modest servings.
Size Varies by Weight: As the product is sold by weight, the specific tray size can vary, directly impacting the number of servings.
Accommodate Hearty Appetites: For bigger eaters, expect closer to 4 to 6 generous portions per tray.
Stretch the Meal with Sides: Serving with a salad, garlic bread, or vegetables effectively stretches the meal and helps satisfy more people.
Cook with Foil: Bake the dish covered with aluminum foil at 400°F for about an hour to prevent the chicken and pasta from drying out.
Mix Before Baking: Since the ingredients are layered, stirring before baking helps distribute the sauce evenly for better flavor.
Store Leftovers Properly: To preserve moisture when reheating leftovers, consider adding a splash of milk or cream.

What to Expect: Average Servings

For the standard deli-prepared tray weighing around 4 to 4.5 pounds, you can typically expect between 6 to 8 modest servings. This estimate assumes a standard portion size, similar to what you might find at a family-style restaurant. This is what makes the Costco chicken alfredo such a great value, as it provides a hearty meal at a very low cost per serving. For example, a single, hungry adult might consume a larger portion, closer to one-sixth of the pan, reducing the overall yield. The most accurate way to gauge your serving size is by considering the needs of your particular family or group.

Factors Influencing Serving Size

Several factors can influence how many meals you get from a single tray of Costco's chicken alfredo:

Appetite of diners: Adults with larger appetites will obviously consume more, while children will eat smaller portions. A tray may feed a larger group of children than adults.
Inclusion of side dishes: If you serve the alfredo alongside other items like a large salad, garlic bread, or steamed vegetables, your guests will eat less pasta, effectively stretching the main course.
Tray size variance: Since the deli product is sold by weight, not a fixed size, the total weight can vary from tray to tray. A slightly smaller tray might feed fewer people, while a larger one could feed more. Always check the label for the exact weight.

A Breakdown of Serving Sizes

Understanding how different variables can impact the total number of meals is key to planning. Here is a comparison to help you estimate based on different scenarios.


Scenario	Estimated Tray Weight	Estimated Servings	Description
Hearty Appetites Only	~4.5 pounds	4-6 generous servings	Ideal for feeding a few very hungry adults, perhaps with minimal or no sides.
Standard Family Meal	~4.5 pounds	6-8 modest servings	The most common scenario for a family of 4 to 6, especially when served with a salad and bread.
Party/Potluck Style	~4.5 pounds	8+ smaller portions	When served as one of many dishes at a gathering, the smaller portions can be spread out among more guests.
Smaller Tray	~2.5 pounds	4-6 modest servings	For smaller groups or families, these trays are often available via Instacart and are sized accordingly.

How to Maximize Your Costco Chicken Alfredo

To get the most out of your purchase, consider these useful tips:

Mix Before Baking: The chicken, pasta, and sauce are often layered rather than mixed. Stirring the ingredients lightly before baking can ensure the sauce coats everything more evenly, resulting in a more uniform dish and potentially richer flavor.
Add Extra Ingredients: Enhance the meal by adding your own ingredients. Stir in some frozen peas for a touch of color and extra vegetables, or add more garlic and seasoning to taste.
Serve with Substantial Sides: Pair the pasta with a large side salad and some garlic bread. This helps fill up diners so they consume less of the richer main course.
Proper Storage: If you have leftovers, they will keep well in the refrigerator for a few days. Reheating can sometimes dry out the chicken, so storing it with some extra sauce or adding a splash of milk or cream during reheating can help preserve moisture.
Divide and Conquer: If you won't eat the whole pan, divide it into smaller, freezer-safe portions before baking. You can then pull out a portion for a smaller meal later.
