Pesto Shelf Life

The shelf life of pesto can vary depending on whether it’s homemade or store-bought. Typically, store-bought pesto comes with a use-by date and can last up to a week after opening, while homemade pesto usually lasts about 5-7 days in the fridge. Understanding the pesto storage duration ensures you enjoy it at its freshest and avoid any potential spoilage.

Storage Tips and Tricks

Proper Refrigeration

To maximize the pesto freshness period, store your pesto in an airtight container in the fridge. This minimizes exposure to air, which can cause oxidation and spoilage.

Freezing Pesto

If you want to keep pesto for longer, consider freezing it. Transfer the pesto into an ice cube tray to create small, single-use portions. Once frozen, transfer the cubes into a freezer-safe bag. Frozen pesto can last up to 6 months.

Signs of Spoiled Pesto

Knowing the pesto spoilage signs is crucial to avoid consuming bad pesto. Look out for:

  • Mold growth
  • Off smell
  • Discoloration (such as turning brown)
