General tips
Greens at 180°–185°F stay vibrant green because the sealed bag prevents oxidation. Boiled greens turn olive-drab within minutes; sous vide greens hold their color for hours.
Spinach, bok choy, and kale all cook in 20–30 min at 180°F. Tougher greens like collards need 45–60 min. Adjust time by texture, not by a universal rule.
Add a knob of butter or a drizzle of sesame oil to the bag. Greens absorb fat beautifully and the flavor infusion during cooking is more even than tossing after.
Drain greens well before serving or finishing. The bag collects a surprising amount of liquid. Squeeze gently or press in a strainer to avoid watery plates.
Anti-tip: do not overcrowd the bag. Greens wilt dramatically and a bag that looks full of raw greens comes out as a thin layer. Use multiple bags for large batches so heat circulates evenly.
Snappy & Bright tips
Bag greens in a single layer to prevent bruising and ensure even cooking.
Shock in ice water immediately for salads to lock in color.
Pat dry before finishing so sauces adhere.
Tender & Velvety tips
Season right after cooking so the greens absorb dressings before cooling.
For broccoli, sear cut sides in a hot pan after the bath for caramelization.
Add a splash of vinegar or citrus to keep flavors bright.
Jammy & Soft tips
Use a clean towel to squeeze out excess liquid before incorporating into dishes.
Season after pressing to avoid washing away flavor with the moisture.
Blend with a bit of cream or stock for an instant sauce for fish or chicken.
