How to Freeze Onions: A Step-by-Step Guide

The key to successful onion freezing is proper preparation. Here’s a step-by-step guide:

1. Select Fresh Onions: Choose firm, blemish-free onions with no signs of sprouting or decay.
2. Clean and Peel: Wash the onions thoroughly and remove any loose skin or roots.
3. Chop or Slice: Cut the onions into the desired size. For smaller onions, you can freeze them whole.
4. Blanch (Optional): Blanching onions in boiling water for a few minutes helps preserve their color and texture. This step is especially recommended for red onions.
5. Cool and Drain: After blanching, plunge the onions into ice water to stop the cooking process. Drain thoroughly.
6. Package and Label: Place the prepared onions in freezer-safe bags or containers, leaving some space for expansion. Label the bags with the date and type of onion.
7. Freeze: Store the packaged onions in the freezer at 0°F (-18°C) or below.

Tips for Freezing Onions

• Freezing Whole Onions: For smaller onions, you can freeze them whole. Simply pack them tightly into freezer bags.
