What is sous vide?
Sous vide is a cooking method where food is sealed in a bag and held in a water bath at an exact temperature for a set time. The bath is set to the finish temperature you want, so the centre and edge cook together. Commercial kitchens use it for ticket consistency, cook-ahead holds, and less overcooking waste. It is not boiling and does not replace your food-safety plan.
What is sous vide?
Foodservice definition, step-by-step method, how it compares with boiling and steaming, and the Canada food-safety notes operators still have to follow.
Key Takeaways
What a commercial kitchen needs to know before clipping a circulator to a bath.
Exact temperature, even doneness
The immersion circulator holds the bath at the target finish temperature so the food does not overshoot the way a pan or oven often does.
Seal, bath, then finish
Season, bag with air removed, cook for the validated time, then sear or broil only when crust and colour matter.
Not boiling or steaming
Boiling is about 100°C / 212°F and aggressive. Steaming is moist heat without precision temperature control. Sous vide holds a lower, set temperature.
Built for service consistency
Same doneness every ticket, better yield on expensive proteins and veg, and cook-ahead options when cooling and retherm rules are documented.
Canada food-premise rules still apply
Use validated time/temperature tables for the item and portion size. Follow provincial food-premise requirements and your HACCP plan for pasteurization, cooling, and hot/cold hold.
Supplies that keep the line reliable
Food-safe bags, nitrile gloves, date/FIFO labels, hotel pans or bath containers, and food-contact sanitizer.
Understanding sous vide in a commercial kitchen
Sous vide (French for “under vacuum,” roughly soo veed) is precision water-bath cooking. On a restaurant line it is a consistency tool: the bath is the doneness, the sear is the finish.
How sous vide works step by step
- Season the food (salt, herbs, fat as needed for the recipe).
- Place in a food-safe vacuum bag or zipper bag; remove air (vacuum or water displacement).
- Set the immersion circulator to the target temperature for that item.
- Cook for the time required for tenderness and, when required, pasteurization for that thickness.
- Remove, pat dry, and finish with sear, torch, or broiler when crust is needed.
- Hold, chill, or serve under your documented procedures.
Typical line setup: circulator clipped to a hotel pan or tank, bags fully submerged, finish station ready at the pass.
Sous vide vs boiling vs steaming vs oven
| Factor | Sous vide | Boiling | Steaming | Conventional oven / pan |
|---|---|---|---|---|
| Temperature control | Exact set point (°C/°F) | ~100°C / 212°F | Near 100°C, less precise | Wide swings; edge overcooks first |
| Evenness edge to centre | High | Low–medium | Medium | Low–medium |
| Overcook risk | Low if time/temp correct | High | Medium | High for lean proteins |
| Texture goal | Uniform doneness; tenderize with time | Soften / extract | Moist heat, no fat barrier | Maillard + drying |
| Typical foodservice use | Repeatable steaks, veg, cook–chill | Stocks, pasta, blanched veg | Veg, dumplings, reheat | Roast, sear, bake |
| Pasteurization path | Time × temp × thickness tables | Not the same process | Not the same process | Separate cook-to-temp rules |
| Finish step | Often sear after bath | Drain / sauce | Plate | Often done in-pan |
Best use for sous vide: when the ticket must hit the same internal doneness every time and you can document time, temperature, and thickness.
Choose boiling / steaming instead when: you need rapid cook of pasta or greens, or you are extracting stock—not holding a precise finish temperature.
What sous vide is not
- Not boiling food in a bag.
- Not a pressure cooker.
- Not “set and forget” without time, thickness, and cooling rules.
- Not a substitute for validated pasteurization charts.
- Not only a home gadget—commercial kitchens use it for yield and repeatability.
Why kitchens use it
- Consistency: same doneness every ticket.
- Holdability: cook ahead, finish to order when procedures allow.
- Yield: less dry, overcooked product.
- Labour: batch prep without gambling every pan.
Foodservice compliance in Canada
Sous vide does not skip cold-chain or hot-hold requirements after the bag comes out. Operators should:
- Use validated time-and-temperature tables for the food and portion thickness.
- Follow provincial food-premise rules and the written HACCP / food-safety plan.
- Control cooling, labelling, and retherm for cook–chill.
- Keep bath water and food-contact surfaces under the same sanitation standards as other prep equipment.
Claims about “safe” sous vide without citing your approved procedures are incomplete. When in doubt, follow your local health authority guidance and Health Canada food-safety principles for cooking and holding.
Supplies that make sous vide reliable
- Vacuum bags / food-safe sealing bags sized for portions
- Nitrile gloves for bagging, seasoning, and plating
- Hotel pans / bath containers and FIFO / date labels
- Sanitizer and food-contact cleaner for the bath area and boards

People Also Ask
Real questions operators search before they set a bath — answered straight.
Is sous vide safe for restaurants?
Yes when you follow validated time/temperature tables for the item and thickness, plus your food-safety plan for cool, hold, and retherm.
Does sous vide replace a sear?
No. The bath sets doneness. The sear builds crust, colour, and aroma.
Can you hold sous vide food for later service?
Many kitchens cook, chill under approved rules, then retherm and finish—only with documented procedures and labels.
What temperature should I use?
It depends on the food, thickness, and desired result. Use a foodservice chart for that item—not one universal number.
Is sous vide the same as boiling in a bag?
No. Boiling is hotter and less precise. Sous vide holds a lower exact bath temperature.
Sous vide vs steaming — which is better?
Neither is universally better. Sous vide wins on precise doneness; steaming wins on speed for many vegetables without bagging.
Frequently asked questions
Is sous vide safe for restaurants?
Yes with validated time/temperature tables and your food-safety plan. Improvising temps or holding outside approved cool/hold rules is the risk—not the bag itself.
Does sous vide replace a sear?
No. Water bath = doneness. Sear / broiler / torch = crust and colour.
Can you hold sous vide food for later service?
Cook–chill in-bag is common when cooling, labelling, storage life, and retherm are written into the plan.
What temperature should I use?
Depends on the food and portion. Use a chart for that item and thickness.
Is this the same as boiling food in a bag?
No. Boiling is ~100°C and aggressive; sous vide holds a lower exact bath temperature.
What equipment do I need on a commercial line?
Immersion circulator, bath container or tank, food-safe bags, thermometer verification, and documented sanitation for the bath area.
