How do you freeze roasted onions?

Freezing roasted onions is a simple way to preserve them for later use. Here's how you can do it:

Step-by-Step Guide to Freezing Roasted Onions

1. Cool the Onions: Allow the roasted onions to cool completely. This is crucial to prevent condensation and ice crystals from forming during the freezing process.

2. Portioning (Using Ice Cube Trays):

   • Portion the cooled onions into ice cube trays. According to one method, don't be afraid to pack them in. This allows you to easily use small amounts of roasted onions later.

3. Freezing in Trays: Place the filled ice cube trays in the freezer.

4. Solid Freezing: Allow the onions to freeze solid.

5. Transfer to Sealed Container:

   • Once the onions are frozen solid, pop them out of the tray or nudge them out with a table knife (if needed).
   • Transfer the frozen onion cubes to a freezer-safe sealed container or freezer bag.

6. Label and Date: Label the container with the contents ("Roasted Onions") and the date of freezing. This helps you keep track of how long they have been stored.

7. Freezing Bags (Alternative): If you don't have ice cube trays, you can spread the cooled onions in a single layer on a baking sheet lined with parchment paper, freeze until solid, then transfer to a freezer bag. This prevents them from clumping together.

Tips for Freezing Roasted Onions

• Cool completely: Ensure the onions are completely cool before freezing to prevent freezer burn.
• Use good quality containers: Freezer-safe containers or bags will help prevent freezer burn and maintain the flavor of the onions.
• Remove excess air: Press out as much air as possible from freezer bags to prevent freezer burn.
• Use within a reasonable time: While properly frozen onions can last for several months, it's best to use them within 2-3 months for the best flavor.

By following these steps, you can easily freeze roasted onions and enjoy them in future recipes.
