Vacuum-packed foie gras preservation
Foie gras is the jewel of French gastronomy. Whether duck or goose, its melting texture and delicate flavor make it an exceptional delicacy. However, it is a fragile and expensive product: therefore, it is crucial to master its storage to avoid spoilage.
In this article, we reveal the secrets to preserving fresh, semi-cooked or cooked foie gras using vacuum sealing, the only method that preserves its taste qualities intact.
Can you freeze foie gras in a vacuum-sealed bag?
Absolutely, and it's even recommended! Vacuum freezing is the ideal method for foie gras. Why?
- Frost protection: The vacuum-sealed bag prevents direct contact with cold air, thus avoiding "freeze burn" which damages the surface of the product.
- Texture preserved: By removing the air, we limit the oxidation of fats (rancidity), which allows the foie gras to retain all its finesse upon defrosting.
How long can you keep vacuum-sealed foie gras?
Vacuum sealing can extend the shelf life by 3 to 5 times compared to traditional storage. However, this depends entirely on the condition of your foie gras (raw, semi-cooked, or preserved).
Summary table of storage times:
| Type of foie gras (Vacuum-packed) | In the refrigerator (+2°C to +4°C) | In the freezer (-18°C) |
|---|---|---|
| Fresh (Raw) Foie Gras | 10 to 15 days | 6 to 10 months |
| Semi-cooked foie gras | 3 to 6 months (depending on the expiration date) | 8 to 12 months |
| Cooked Foie Gras (Preserved) | Several years (Closet) | Useless |
Warning: Never store fresh or semi-cooked foie gras at room temperature, even vacuum-sealed. Only sterilized preserves (jars) are suitable.
The essential tool for your Foie Gras
To avoid crushing your foie gras during packaging, use our machine equipped with the "Pulse" function (manual vacuum control).

Two things need to be distinguished:
- The "Use By" date: "Use by...". For fresh foie gras, never exceed this date, whether vacuum-packed or not. There is a risk of bacterial contamination.
- The "Best Before" date: "Best before...". For canned goods or certain semi-cooked products, the product remains safe after the date, but may lose some flavor.
The advantage of vacuum sealing is that it prevents external contamination. If the bag is well sealed to the product and there is no suspicious odor upon opening, the preservation has been optimal.
How do you vacuum-seal foie gras without crushing it?
Foie gras is a soft product. Using a vacuum sealer too roughly risks flattening it. Here is our method:
-
Chill the foie gras: Always handle it when it is very cold (straight from the fridge), it will be firmer and less prone to being crushed.
-
Use the "Pulse" function: This is the secret. Use a machine that allows you to control the suction manually. Suction the air until the bag conforms to the shape of the liver, then stop before it starts to deform.
-
Seal immediately: Initiate the welding process to secure the package.
By following these tips, you can prepare your terrines in advance for the holidays without any stress!
