How Long Can Tuna Pasta Stay in the Fridge?

Tuna pasta is a perishable food item that can spoil if not stored properly. When cooked, it can last in the fridge for three to five days. Any longer than that, and it becomes a risk for foodborne illnesses.

Temperature and Humidity

The temperature of your fridge plays a crucial role in keeping your food fresh as bacteria multiply more quickly at a warm temperature. Therefore, it’s best to keep tuna pasta at a temperature of 40 degrees Fahrenheit or below.

Sauce and Ingredients

The ingredients used to prepare the tuna pasta may affect its shelf life. For example, the addition of extra proteins such as chicken or shrimp will shorten the shelf life compared to plain tuna pasta dishes. In contrast, drying out the toppings or ingredients will help boost its lifespan.

The same applies to egg sauces or carbonara-style sauces. You may add these sauces while cooking, or you can refrigerate them separately and combine them once reheated. Adding cheese before refrigerating also helps boost the pasta’s lifespan.

Containers and Packaging

Using an appropriate container or packaging material is essential for storing tuna pasta safely. Nonporous materials like glass containers or good quality sealable plastic bags are the best option as they keep moisture out and reduce air exposure.

Be cautious when using containers as metal containers may affect the taste of acidic ingredients like tomato sauce over time. Similarly, styrofoam or paper-only containers may not provide a tight seal, leading to air exposure and spoiling of your tuna pasta.
