3) Tips for Freezing Red Onions

When freezing red onions, keep these tips in mind to ensure the best results:

– Prevent Onion Smell: Red onions have a strong odor that can permeate other foods in the freezer. To prevent this, wrap the onions tightly in plastic wrap or place them in a sealed freezer bag.

– Freeze According to Preferred Preparation: If you have specific recipes in mind, consider freeze red onions in the form that you will most likely use them. For example, if you often saut onions for stir-fries, freeze them already diced.

4) Longevity of Frozen Red Onions

Frozen red onions can be stored in the freezer for up to three months. While they will still be safe to eat beyond this timeframe, their texture and flavor may deteriorate.

5) Refrigerator Storage

If you have leftover fresh red onions and don’t want to freeze them, they can be stored in the refrigerator for up to 1-2 months. Place them in a cool, dry area, such as the crisper drawer, to maximize their freshness and prevent sprouting.

Repeated freezing and thawing can lead to a loss of flavor and changes in texture. To prevent waste, only thaw the amount you need for a particular recipe.
