Overview
Broccoli, kale, asparagus, and other greens stay vivid when they cook gently. Finish them with a quick sauté or roast for browned edges and a little contrast.

Thicker pieces need the longer end of the cook time. Keep everything in one layer, and read the Cook safely section before serving.
Choose your texture
- 176°–178°FSnappy & Bright
- Bright vegetables with a tender center and a little snap.
Best for
- Asparagus
- Green beans
- Broccolini
Notes
- Finish with toasted nuts or seeds for crunch.
Tips
- Bag greens in a single layer to prevent bruising and help with even cooking.
- Pat dry before finishing so sauces adhere.
- 180°–182°FTender & Velvety
- Softer greens that soak up garlic oil, miso butter, or sauce.
Best for
- Broccoli
- Green beans
- Sugar snap peas
Notes
- Toss with miso butter or sesame oil after the bath.
- Sprinkle with chili crisp for heat.
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.
- 183°–185°FJammy & Soft
- Very soft greens for dips, spreads, or a braised-style side.
Best for
- Spinach
- Kale
- Swiss chard
Notes
- Squeeze out moisture and fold into artichoke dip or spinach pie.
- Finish with crème fraîche and lemon for a side.
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.
Get it ready
- Wash the greens well, trim tough stems, and cut everything into even pieces.
- Arrange the greens in a loose layer with a little oil, butter, and seasoning.
- Seal gently so the leaves are not crushed.
Finish and serve
- Drain away any extra liquid from the bag.
- Toss the warm greens briefly with garlic oil, butter, sesame oil, or sauce.
- Serve right away, or press very soft greens before adding them to a dip or filling.
Useful 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 minutes at 180°F. Tougher greens like collards need 45–60 minutes. 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.

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.
