Bastien Sous Vide
Sous vide is a precision cooking method where food is vacuum-sealed and cooked in a temperature-controlled water bath at 50-85°C for 30 minutes to 72 hours — produces edge-to-edge even doneness impossible to achieve with conventional cooking.
Sous vide (pronounced "soo-VEED") is a cooking method where food is sealed in a bag and cooked in a water bath held at a precise, constant temperature (typically 50-85°C / 122-185°F) for 30 minutes to 72 hours. The name is French for "under vacuum," referring to the vacuum-sealed bags originally used in the technique. It produces results that are nearly impossible with conventional cooking: edge-to-edge doneness with no gradient of overcooked meat near the surface.
I started sous vide cooking with a $70 immersion circulator and a pot I already owned. The first steak I pulled out of that water bath was the most evenly pink piece of meat I'd ever cooked, and I was hooked.
How do you pronounce sous vide?
Two syllables: soo-VEED. The "s" in "sous" is silent, and the "d" in "vide" is pronounced. Many English speakers say "soo-VYD" or drop the final "d," both incorrect. It rhymes with "new creed."
How does sous vide cooking work?
Because the water never exceeds your target temperature, the food can't overcook past that point. A steak set to 54 °C (129 °F) will be 54 °C from edge to edge, not just at the center. Use an instant-read thermometer after the sear to confirm you haven't overshot.
Where did sous vide come from?
Sous vide was developed in the early 1970s in France. Engineer Georges Prud'homme first described vacuum-cooking for industrial food preservation, and chef Bruno Goussault began researching the effects of temperature on various foods. The technique gained its first fine-dining application when chef Georges Blanc used it to cook foie gras: the vacuum seal prevented the significant fat loss that occurred with traditional methods.
Through the 1980s and 1990s, sous vide remained a restaurant secret. High equipment costs kept it out of home kitchens. That changed around 2010 when affordable immersion circulators hit the consumer market, dropping from several thousand dollars to under $100.
What are sous vide times and temperatures by food?
The wide time windows are one of sous vide's best features. A steak at 54 °C is equally good at 1 hour or 3 hours in the bath.
How does sous vide compare to other cooking methods?
Confit is another low-temperature French technique, but it cooks food submerged in fat rather than in a water bath.
What are the advantages of sous vide?
Precision. You pick the exact internal temperature. A medium-rare steak is medium-rare throughout, not just in the center with a gray band around it.
Consistency. Once you find a time and temperature you like, you can reproduce it every single time.
Hands-off cooking. Set it and walk away. Most sous vide cooks have a wide time window, so timing doesn't need to be exact.
Hard to overcook. The water never exceeds the target temperature, so food reaches equilibrium and holds there. A chicken breast at 65 °C can't become 75 °C in a 65 °C bath.
Better yields. Sealed bags retain nearly all the juices. Meat typically loses 5–10% of its weight sous vide versus 20–30% with traditional roasting.
What are the limitations of sous vide?
No browning. A water bath can't produce the Maillard reaction. You need a finishing step (screaming-hot cast iron, a grill, or a kitchen torch) for color and crust.
Longer cook times. Water at 54 °C heats food much more slowly than a 230 °C oven. A steak takes 1–4 hours sous vide versus 10–15 minutes on a grill.
Equipment required. You need an immersion circulator and bags at minimum. Vacuum sealers help but aren't strictly necessary. Standard zip-lock freezer bags work for cooks below about 70 °C. At higher temperatures or for long cooks, silicone bags or proper vacuum-seal bags hold up better.
Texture preferences. Some people find sous vide proteins, especially chicken and pork, unfamiliar. The even doneness can read as "soft" compared to the firmer texture from higher-heat methods. This is personal taste, not a flaw. After cooking a few dozen chicken breasts sous vide, I actually prefer the texture to oven-baked, but I understand it's not for everyone.
Is sous vide safe for food?
Cooking at low temperatures for extended periods raises a fair question: is sous vide safe? The short answer is yes, as long as you follow basic guidelines.
Pasteurization depends on both temperature and time. A chicken breast held at 60 °C for long enough is just as safe as one cooked to 74 °C instantly. Douglas Baldwin's pasteurization tables are the gold standard reference here. The key rules:
Vacuum sealing also prevents freezer burn when storing food long-term, which is a nice side benefit of owning a vacuum sealer.
How do you get started with sous vide?
Start with steak. It shows the biggest difference from conventional cooking and is forgiving on time.
Dry the surface before searing. Pat the protein thoroughly with paper towels after removing it from the bag. Moisture is the enemy of a good crust.
Watch carryover cooking. The finishing sear adds heat. Keep it short (45–60 seconds per side) to avoid pushing the interior temperature past your target. Let the meat rest briefly before slicing.
Save the bag juices. The liquid in the bag is concentrated, flavorful stock. Reduce it in a pan for a quick sauce.
Sous vide in Fond
Fond's recipe timers help you track long sous vide cooks without watching the clock. Set a timer for your target cook window, and Fond notifies you when it's time to pull the bag and start the finishing sear.
