Things to Consider Before Freezing Pesto

Before freezing pesto, consider the following factors:

Techniques for Freezing Pesto

There are techniques you can use when freezing pesto to ensure optimal results. Let’s explore them below:

Freezing Pesto in Ice Cube Trays

This method allows you to portion and freeze pesto in small, convenient servings.

  • Prepare the pesto according to your desired recipe, ensuring it is well blended.
  • Clean and dry ice cube trays thoroughly.
  • Spoon the pesto into each compartment of the ice cube tray, filling them about 3/4 full.
  • Tap the ice cube tray gently on the countertop to remove any air bubbles.
  • Place the ice cube tray in the freezer and freeze until the pesto is solid, usually for about 4-6 hours.
  • Once the pesto cubes are frozen, remove them from the tray and transfer them to airtight freezer bags or containers.
  • Label the bags or containers with the date of freezing for easy reference.

Freezing Pesto in Freezer Storage Containers

If you prefer larger portions of frozen pesto, you can use freezer-safe containers.

  • Prepare the pesto as usual, ensuring it is well blended.
  • Spoon the pesto into clean and sterilized freezer storage containers.
  • Leave some headspace in the containers to allow for expansion during freezing.
  • Smooth the surface of the pesto and ensure there are no air pockets.
  • Seal the containers tightly to prevent air exposure and potential freezer burn.
  • Label the containers with the date of freezing for easy reference.

How to Thaw and Use Frozen Pesto

Thawing and using frozen pesto is a simple process. Here are a few methods you can use:


Refrigerator Thawing: Transfer the frozen pesto container or pesto cubes from the freezer to the refrigerator. Allow them to thaw slowly overnight or for several hours until they reach a spreadable consistency.

Cold Water Thawing: If you need to thaw pesto more quickly, place the sealed bag or container in a larger container of cold water. Change the water every 30 minutes to maintain its cold temperature. Thawing time will vary depending on the quantity and thickness of the pesto.

Using Thawed Pesto

Stir and Adjust: Once the pesto is thawed, give it a good stir to reincorporate any separated ingredients. If the texture seems grainy, you can blend or process it again to achieve a smoother consistency.

Flavor Enhancements: Thawed pesto can be customized by adding a drizzle of fresh olive oil, a sprinkle of grated Parmesan cheese, or additional fresh basil leaves to enhance its flavor before serving.

Proper Storage of Frozen Pesto

Proper storage is essential to maintain the quality and taste of frozen pesto. Follow these guidelines:

  1. Shelf Life: Frozen pesto can be stored for up to 3-4 months. It’s recommended to use it within this time frame for the best flavor and texture.
  2. Airtight Packaging: Ensure that the freezer bags or containers used for storing pesto are airtight to prevent air exposure and maintain its vibrant color and taste.
  3. Labeling: Clearly label the bags or containers with the date of freezing for easy reference.
