COOKING TIPS
In the kitchen.
- 1Add directly from the freezer to hot pans for soups, stews, casseroles, and sauces; no thawing is necessary.
- 2Because they release more water than fresh onions, sauté them until the moisture has evaporated to achieve better browning and flavor concentration.
- 3Best used in cooked dishes as the freezing process softens their texture, making them less suitable for raw applications like salads.
- 4Use as a convenient time-saver to build a flavor base (mirepoix) for countless recipes without the tears from chopping.
STORAGE
Keep it fresh.
- Store in an airtight freezer bag or container at 0°F (-18°C) or below to prevent freezer burn.
- For best quality, use within 6 to 8 months of purchase. Do not refreeze after thawing.

How do I cook with frozen onions?
Frozen onions can be added directly to most hot dishes without thawing. They are excellent for sautéing, roasting, or incorporating into soups, stews, casseroles, and sauces. Just be aware they release more water than fresh onions, so adjust cooking time accordingly.
Do frozen onions need to be thawed before cooking?
Generally, no, frozen onions do not need to be thawed before cooking. For most applications like sautéing or adding to hot dishes, you can use them straight from the freezer. Thawing them first can sometimes make them mushier.
What dishes are best suited for frozen onions?
Frozen onions are ideal for dishes where their texture isn't the primary focus, such as soups, stews, chili, casseroles, stir-fries, and sauces. They blend well into cooked dishes, providing flavor without the need for chopping fresh onions.
How long do frozen onions last in the freezer?
Properly stored, frozen onions can last for 6 to 8 months in the freezer while maintaining optimal quality. They will remain safe to eat beyond that, but their texture and flavor might degrade over time.
Do frozen onions taste different from fresh onions?
Frozen onions retain much of the flavor of fresh onions, but their texture will be softer and less crisp due to the freezing process. They are best used in cooked applications where a firm texture isn't required, as they won't have the same bite as raw or freshly sautéed onions.
