The Sous Vide Temperature Calculator provides the precise water bath temperature for achieving your desired doneness with 12 different proteins and vegetables. Unlike conventional cooking where oven or pan temperature far exceeds the target internal food temperature, sous vide works by setting the water bath to exactly the desired final core temperature — making it physically impossible to overcook the food as long as it is held within safe time windows.
The water bath temperature is the most important setting in sous vide cooking and represents a direct cooking choice rather than a process variable. For beef steak: rare (54°C/129°F) produces a deep red, very tender result; medium-rare (57°C/135°F) is the most popular choice with a warm pink center and maximum juiciness; medium (63°C/145°F) gives a slightly firmer, pink-beige center; well done (68°C/154°F) produces a fully cooked, firmer but still moister-than-conventionally-cooked result.
Fish and seafood have very different optimal temperature ranges than red meat. Salmon shows its best silky, translucent texture at 40–47°C (104–117°F) — temperatures that would be far below safe cooking in conventional methods but are safe in sous vide due to the extended, uniform heating. Shrimp and lobster are notoriously easy to overcook conventionally; sous vide at 52–55°C gives the sweet, tender texture of perfectly cooked shellfish impossible to replicate reliably with conventional methods.
Vegetables require much higher temperatures (82–90°C/180–194°F) than proteins because cell wall softening requires pectin degradation at temperatures near boiling. Sous vide for vegetables is less about doneness level and more about precise texture control — root vegetables at 85°C for 1–2 hours produce perfectly tender, intensely flavored results with minimal nutrient loss compared to boiling.
This calculator also outputs both Celsius and Fahrenheit readings and indicates whether the selected temperature guarantees pasteurization over the minimum cooking time, which is critical for food safety guidance.
The temperature values in this calculator are based on the denaturation temperatures of key muscle proteins and the FDA/USDA/food science consensus on safe cooking temperatures with time. Myosin begins denaturing at 50°C and is fully denatured by 55–57°C (explaining why medium-rare beef is cooked to 57°C). Actin denatures at 65–70°C (explaining why well-done beef is less juicy — both major structural proteins are fully denatured and have expelled more water). Collagen conversion to gelatin occurs slowly at 60–65°C over many hours. Fahrenheit conversion: F = (C × 9/5) + 32.
The recommended temperature is the water bath setting — your immersion circulator should be set exactly to this value. Precision to 0.5°C matters for fish and eggs where the texture window is narrow. For beef and other red meat, ±1°C is acceptable. If your circulator lacks precision, always err on the side of 0.5–1°C higher for food safety. After sous vide, always sear quickly at maximum heat (30–60 seconds per side) to develop the Maillard crust and eliminate surface pathogens that may not have reached full pasteurization temperature.

Duck breast at 57°C produces a rosy-pink center with rendered, crispy skin after searing. Duck fat renders better with longer times at this temperature (2–3 hours) before a hard pan sear.

Lobster at 55°C for 30–45 minutes yields buttery, succulent tail meat — the texture that characterizes premium restaurant preparations, impossible with boiling.
Beef rare sous vide is cooked at 54°C (129°F). At this temperature, the beef has a warm red interior, extremely tender texture (myosin is the only significantly denatured protein), and maximum moisture retention. If you prefer true rare but slightly warmer throughout (not cold center), use 52–54°C. For those who want rare-leaning medium-rare, 55–56°C is a sweet spot. Most professional chefs favor 54–57°C depending on cut and personal preference.
The recommended range for chicken breast sous vide is 60–65°C (140–149°F). At 60°C for 90+ minutes, chicken is fully pasteurized with a moist, slightly translucent texture that feels underdone to many diners but is completely safe. At 63–65°C, the texture is more conventional — white, moist, and tender. At 74°C (conventional instant-kill temperature), chicken is fully safe in under 1 minute but becomes drier. Most home cooks prefer 63–65°C for a safe, familiar texture. Never serve chicken below 60°C as pasteurization is not guaranteed at shorter times.
Sous vide salmon at 40–42°C for 30 minutes produces a barely-set, translucent texture similar to sashimi but cooked. At 45–47°C, the texture is silky, tender, and slightly opaque — the preferred range for most chefs. At 52°C, salmon is conventionally done with full opacity but remarkable moisture. At 60°C, salmon is safe for immunocompromised individuals but may become slightly dry. Choose based on the diner's health status and preference. The 45–47°C range is the molecular gastronomy standard.
Yes — this is the defining feature of sous vide. You set the water bath to exactly the desired final core temperature. The food will never exceed this temperature, only approach it asymptotically from below. This is fundamentally different from oven cooking where oven temperature (180–230°C) far exceeds the target internal temperature (57–74°C). In sous vide, the bath temperature equals the target temperature, so precise calibration of your circulator is essential. A well-calibrated Joule, Anova, or professional circulator should hold temperature to within ±0.1°C.
Modern food safety guidelines allow pork to be safely eaten at 60°C (140°F) when held for sufficient time, which is medium doneness with a slight pink tinge — moist, tender, and juicy. The old USDA guideline of 74°C (well done) was updated in 2011 to allow 62.8°C (145°F) with a 3-minute rest. Sous vide pork at 58–60°C gives the best texture: tender, juicy, and slightly pink without any safety concern when minimum times are observed. For pork tenderloin, 58°C is exceptional; for pork chops, 60–63°C is ideal.
Vegetables require 82–90°C (180–194°F) because cell wall softening requires pectin degradation, which occurs near boiling temperature. Carrots, beets, and turnips: 85°C for 60–90 minutes gives tender, vibrant results. Potatoes: 85°C for 60–90 minutes for cubes; 90°C for whole small potatoes. Asparagus: 85°C for 10–15 minutes. Artichokes: 85°C for 45–60 minutes. Green beans: 85°C for 15–20 minutes. Onions: 90°C for 1 hour for fully sweet, jammy results. Always season in the bag with fat (butter, olive oil) for best flavor transfer.
A dedicated immersion circulator or sous vide machine is strongly recommended for temperature precision. However, you can approximate sous vide using a large pot, a probe thermometer, and careful manual temperature management on the stovetop. The challenge is maintaining ±1–2°C for 1–4 hours without a circulation pump. A slow cooker on the lowest setting sometimes maintains 60–65°C; verify with a thermometer before cooking. For practical home cooking without a machine, oven-steaming in a sealed vessel is a closer approximation than stovetop poaching.
The food safety danger zone is 4–60°C (40–140°F), where bacterial growth is rapid. In sous vide, the concern is that food spends time in the danger zone during heating. At 54°C bath temperature, the surface of the food reaches 54°C immediately, but the center may spend 30–90 minutes below 60°C. This is acceptable for whole muscle cuts (beef, pork, lamb) where surface pathogens are killed quickly, but requires attention for fish (parasites) and poultry (Salmonella at the interior). Always observe minimum time requirements and never leave food unattended below pasteurization temperature.
Sous vide eggs (cooked in shell) show dramatic texture differences across a narrow temperature range: at 63°C for 45–90 minutes, whites are barely set and custard-like, yolk is warm and flowing — the famous Japanese onsen tamago. At 64°C, whites are more set but yolk still jammy. At 75°C, whites are fully firm, yolk is slightly soft-boiled style. At 85°C for 15 minutes, hard-boiled equivalent. The most popular sous vide egg is 63–64°C for 60–75 minutes, which produces a uniquely silky, uniform texture impossible with boiling.
For fish, shellfish, and vegetables: yes, adding fat (butter, olive oil) carries fat-soluble flavor compounds and improves heat transfer. For red meat at temperatures above 55°C, fat addition is optional — the meat renders its own fat. However, for lean cuts (chicken breast), adding butter or flavored fat improves perceived juiciness. Aromatics (garlic, thyme, rosemary) can be added to the bag but use with caution at lower temperatures (below 60°C) as raw garlic and herbs can harbor Clostridium botulinum in the anaerobic bag environment. Use dried herbs or blanch aromatics first for safety in long, low-temperature cooks.
