Can you vacuum seal asparagus?
Asparagus season is short and intense. Whether green or white, they are delicious but lose their freshness in just a few days. How can we enjoy them all year round?
The answer is vacuum sealing. This technique not only allows you to freeze your asparagus without it becoming mushy, but also to cook it to perfection, concentrating all its flavors.
Storage: How to freeze asparagus in a vacuum bag?
Never freeze raw asparagus directly, as it will become waterlogged. Here's the pro method:
- Preparation: Wash the asparagus. Peel the white ones (no need for the thin green ones) and cut off the tough ends.
- Blanching (Crucial): Plunge them into boiling water for 2 minutes, then immediately into a bowl of ice water. This sets the color and texture.
- Drying: Pat them dry thoroughly. Moisture is the enemy of vacuum sealing.
- Vacuum sealing: Place them flat in the bag. Be careful with the fragile tips!

This is the method used by great chefs to obtain asparagus that is tender but firm, with an intense taste (since they are not cooked in water).
Steps for perfect cooking:
- Season: In the bag, put your raw asparagus, a knob of butter, a pinch of salt and a little lemon juice.
- Seal: Create a vacuum.
-
Cooking: Immerse the bag in a bain-marie (with a immersion circulator) at 85°C .
- Green Asparagus: 12 to 15 minutes.
- White Asparagus: 25 to 35 minutes (depending on the size).
- Serving: Open and enjoy directly, or fry them for one minute to brown them.
