Overview
Asparagus stays bright and tender with a little snap when it cooks in one flat layer. Finish with butter and lemon, or give the spears a quick char.

| Texture | Bath setting | Cook time | Longest time |
|---|---|---|---|
| Crisp-Tender | 180°–183°F | 30 minutes | 1 hour |

Thicker pieces need the longer end of the cook time. Keep everything in one layer, and read the Cook safely section before serving.

Get it ready
- Snap or trim away the woody ends.
- Arrange the asparagus in one layer with butter, garlic, or herbs.
- Seal gently and keep the bag fully submerged while the spears cook.
Finish and serve
- Take the asparagus out of the bag and spoon over the butter and juices.
- Serve as is, or sauté for 1–2 minutes for a little color.
- Finish with lemon, cheese, nuts, or herbs.
Useful tips
- Only sous vide pencil-thick or thicker spears. Thin spears wilt and turn limp in any bath, no matter how brief. The thicker stalks have enough structure to hold their bite and benefit from the gentle, even cook. Skinny asparagus belongs in a hot pan.
- Snap, don't cut, the woody ends. Hold each spear at both ends and bend — it'll snap at the natural break point between the tender top and the woody bottom. This is more reliable than cutting an inch off the bottom and risks zero waste.
- Cook at 183°F for 15 minutes for crisp-tender. Anything longer and the asparagus turns flabby; anything shorter and it's still squeaky. The 15-minute mark gives you bright green, slightly snappy spears that hold their texture on the plate.
- Add butter and lemon zest to the bag, but never the lemon juice. Lemon juice in the bag turns the asparagus grey and dull. The zest gives you the bright lemon flavor without the discoloration. Squeeze the juice over the finished spears at the table.
- Anti-tip: don't peel the bottom inch of the spear. The peel is part of the asparagus's natural texture, and peeling makes the spears wobbly and slimy. If your asparagus is so tough it needs peeling, snap off another inch instead.

Cook safely
Wash your hands for at least 20 seconds, then rinse the vegetables under running water. Do not use soap on produce. Keep it away from raw meat and seafood, use clean tools, and serve it right after cooking. These times are for texture; they are not instructions for canning, sealed storage, chilling, or reheating. Never leave a sealed bag at room temperature.
