This guide was put together from published food-science pasteurization data and patterns I’ve noticed across dozens of my own cooks and hundreds of forum threads — not just marketing copy.
If you’ve ever pulled a steak off the grill and second-guessed whether it’s actually medium-rare or just… pink-ish, this guide is for you. The whole point of a sous vide steak temperature chart is that you stop guessing — you pick the exact doneness you want, set the water bath to that number, and the steak simply cannot go past it. Below is the full breakdown of sous vide steak temperature by doneness level, how thickness changes your cook time, and the safety numbers behind why it works even at temperatures well below what you’d expect from a stovetop.
Sous Vide Steak Temperature by Doneness
This is the core chart — pick your doneness, set your circulator to that temperature, and it holds there until you’re ready to sear.
| Doneness | Sous Vide Temperature | What It Looks Like |
|---|---|---|
| Rare | 120–128°F (49–53°C) | Cool red center, very soft |
| Medium-Rare | 129–134°F (54–57°C) | Warm red-pink center, most popular choice |
| Medium | 135–144°F (57–62°C) | Pink throughout, firmer |
| Medium-Well | 145–155°F (63–68°C) | Slightly pink center, noticeably firmer |
| Well Done | 156°F+ (69°C+) | No pink, firmest texture |
If you’re new to the whole method and want the bigger picture before diving into steak specifically, our beginner’s guide to what sous vide actually is covers how the water bath itself works and why time and temperature matter together, not just temperature alone.
Sous Vide Steak Time by Thickness
Temperature controls doneness, but thickness controls how long the steak needs to sit in the bath to reach that temperature all the way through and to safely pasteurize. For a thick cut running toward the top of that range, a dedicated container with a lid — like the picks in our best sous vide containers guide — cuts down on the evaporation you’d otherwise have to top up by hand over a multi-hour cook. This is the part beginners get wrong most often: heating time doesn’t scale in a straight line with thickness — it scales closer to the square of it. A steak twice as thick needs roughly four times as long to heat through, not just double. Rushing a thick cut based on a rough guess is the single most common sous vide steak mistake.
| Steak Thickness | Minimum Time to Heat Through | Recommended Range |
|---|---|---|
| 1 inch (2.5 cm) | ~40–60 minutes | 1–2.5 hours |
| 1.5 inches (3.8 cm) | ~1.5–2 hours | 1.5–3 hours |
| 2 inches (5 cm) | ~2.5–3.5 hours | 2.5–4.5 hours |
A useful thing about sous vide that traditional cooking doesn’t offer: once a steak reaches its target temperature, it doesn’t overcook by sitting longer in the bath (within a safe window — more on that below). That’s why the “recommended range” column is wide. A 1-inch steak left in for 2.5 hours instead of 1 hour comes out exactly the same doneness, just slightly more tender, since the extra time gives connective tissue a bit more time to break down.
A note on precision: the ranges above are conservative estimates meant to keep beginners safely on the long side, not exact lab measurements — actual time varies with your specific cut, starting temperature, and equipment. If you want an exact number for an unusual thickness or a frozen steak, Douglas Baldwin’s tables remain the most detailed reference available for free.
Why These Numbers Are Actually Safe
This is the question almost everyone asks the first time they see “129°F” on a sous vide steak temperature chart, since it’s well below the instant-kill number most of us grew up hearing. The short version: safety comes from the combination of temperature and time, not temperature alone.
The USDA Food Safety and Inspection Service’s actual pathogen-reduction standard isn’t a single instant-kill number — it’s a specific bacterial reduction that can be reached at a lower temperature if you hold it there long enough. Researcher Douglas Baldwin published the pasteurization tables most sous vide cooks still reference today: beef held at 130°F reaches a safe pasteurization level in roughly 112 minutes, while the same result at 135°F takes only about 31 minutes.
Practically, this means: as long as your steak is thick enough that the recommended cook time in the table above already clears the pasteurization hold time for your chosen temperature, you’re covered. For most steaks over an inch thick, this works out naturally — the time it takes to heat the center already exceeds the minimum hold time needed. If you’re weighing this precision against just braising a tough cut in a slow cooker instead, our sous vide vs slow cooker guide breaks down when each method actually makes more sense. The same time-and-temperature safety logic applies to other proteins too — if chicken is next on your list, our sous vide chicken temperature guide walks through the same kind of chart for breast, thighs, and legs
Sear It Right: The Step Sous Vide Doesn’t Do
Sous vide handles the inside of the steak — even, edge-to-edge doneness at exactly the sous vide steak temperature you set, with zero guesswork. What it doesn’t do is brown anything, since water never gets hot enough for browning reactions to happen. That’s why every sous vide steak needs a fast, hot sear right after the bath:
- Remove the steak from the bag and pat it completely dry with paper towels — any surface moisture steams instead of searing.
- Heat a cast-iron or stainless pan until it’s just short of smoking, with a high-smoke-point oil (avocado or refined vegetable oil).
- Sear 45–60 seconds per side, pressing down lightly for even contact. Add a knob of butter and a smashed garlic clove in the last 30 seconds for extra flavor if you like.
- Rest for 2–3 minutes before slicing — since the inside is already at temperature, this rest is much shorter than a traditionally cooked steak needs.
Community FAQ
What’s the best sous vide steak temperature for beginners? 131–132°F is a forgiving, popular sous vide steak temperature to start with for medium-rare — it’s easy to sear well and gives you a clear sense of what sous vide actually changes about a steak.
Can I leave my steak in the sous vide bath too long? Within the recommended range in the table above, no — that’s the main advantage. But don’t leave any steak in a bath below 130°F for more than about 4 hours total, and always sear and eat (or rapid-chill) promptly after removing it from the bag.
Why does my steak look gray instead of red right out of the bag? That’s completely normal — sous vide doesn’t brown or color the surface at all. The color and crust come entirely from the sear afterward.
Do I need a vacuum sealer to sous vide a steak? No. The water displacement method — lowering an unsealed ziplock bag slowly into the water so pressure pushes the air out before sealing — works fine for a single steak and costs nothing extra.
Should I season the steak before or after the sous vide bath? Before — salt and pepper (and any dry herbs) go on before sealing. Save fresh garlic, butter, and fresh herbs for the sear, since they can turn bitter or overpower the meat if cooked for hours in the bag.
