Key takeaways
- Temperature sets the doneness of a sous vide burger; medium-rare lands around 129 to 134F (54 to 57C).
- Ground beef is higher risk than a whole steak because surface bacteria get mixed throughout, so you must pasteurise by holding time and temperature together.
- Time sets pasteurisation, not doneness, so a longer hold makes a rare-looking burger safe without changing its colour.
- Sous vide adds no browning, so finish with a very hot, very fast sear for crust without overcooking the inside.
A sous vide burger is a ground-beef patty cooked in a precisely temperature-controlled water bath, so the temperature you set is the doneness you get, then pasteurised by time and finished with a hard sear for crust. The first burger I cooked this way changed how I think about pink in the middle: even, juicy, and safe, with no guesswork about the centre.
Doneness temperature
Set the water to the doneness you want; the patty cannot get hotter than the bath, so the colour comes out uniform from edge to edge. The ranges match a steak: rare is about 120 to 128F (49 to 53C), medium-rare about 129 to 134F (54 to 57C), and medium about 135 to 144F (57 to 62C)1. A grill gives you a steep gradient and a guessed centre, while here the whole patty lands on one doneness with no grey band. The temperature decides the colour and feel; what makes a pink burger safe is the next part. For the why behind this, see how does sous vide work.
Ground-meat safety
Ground beef is higher risk than a whole steak, so you must pasteurise it rather than just bring it to temperature. On an intact steak, bacteria sit on the outside surface, which a sear destroys. When beef is ground, that surface gets mixed all the way through the patty, so the centre can carry the same bacteria as the outside2. Sous vide handles this because pasteurisation is time plus temperature together, not temperature alone: a lower temperature simply needs a longer hold. That is how a medium-rare burger at 129 to 134F (54 to 57C) can be made safe, by holding it long enough at that temperature, which a hot grill cannot do for a pink centre. Use Douglas Baldwin’s tables for the exact hold at your temperature, and never improvise the number3. I always set a timer from the moment the patty reaches temperature, not from when it went in. Our food-safety guide covers the full reasoning, and pasteurization explained goes deeper on the time-temperature link.
Hold time
Time sets pasteurisation, not doneness, so a longer cook makes a rare-looking burger safe without changing its colour. Timing depends on thickness, not weight: a patty about one inch thick reaches temperature in roughly an hour, but you keep it in for the pasteurisation hold your chart specifies at your set temperature. Lower temperatures need longer holds. The danger zone runs from 40 to 140F (4 to 60C), and cooking below about 130F (54.4C) is for short cooks only, so a very low, very long burger hold is not the move. Cooking frozen patties straight from the freezer is fine; add roughly 50 percent more time so the centre reaches and holds your target. See can you overcook sous vide for how far you can push the window before texture suffers.
Higher-risk eaters
If you are serving people who are pregnant, very young, elderly, or immunocompromised, skip the pink and cook to the standard safe internal temperature instead. The USDA target for ground beef is 160F (71C), measured in the centre of the patty4. Sous vide still helps here: set the bath to 160F and the burger holds exactly there without drying out the way a grill can. This is the one case where I do not chase a rare centre; the safety margin matters more than the colour.
The sear
Sous vide adds no browning, so you finish the burger with a very hot, very fast sear for crust and colour. The water sits far below the Maillard browning range, so the patty comes out cooked but pale and grey on the surface. Pat it bone dry first, because surface water steams instead of browning, then sear it in a smoking-hot cast-iron pan or on a hot grill for well under a minute a side. Keep it short so the residual heat does not push the inside past your target1. A thin slice of cheese added in the last seconds melts perfectly over the hot crust. Full method is in how to sear after sous vide.

Frequently asked questions
What temperature do you cook a sous vide burger?
Set the water to the doneness you want, the same range as a steak: rare is about 120 to 128F (49 to 53C), medium-rare about 129 to 134F (54 to 57C), and medium about 135 to 144F (57 to 62C). The patty comes up to that temperature and stops, so the colour is uniform edge to edge. Because ground beef is higher risk than whole muscle, hold it long enough to pasteurise at your chosen temperature rather than cooking for the bare minimum.
Is it safe to eat a medium-rare sous vide burger?
It can be, if you pasteurise it. With ground beef, surface bacteria are mixed all through the patty, so it is riskier than a steak where bacteria stay on the outside. Sous vide lets you hold the burger at a lower temperature long enough to make it safe, which is something a hot grill cannot do for a pink centre. Use Douglas Baldwin's tables for the hold time at your temperature, and if you are serving people who are pregnant, very young, elderly, or immunocompromised, cook to the USDA safe internal temperature of 160F (71C) instead.
How long do you sous vide a burger?
Time depends on thickness, not weight, and on pasteurisation rather than doneness. A typical patty about one inch thick reaches temperature in roughly an hour, but you should keep it in long enough to pasteurise at your set temperature, which a chart will tell you. Lower temperatures need longer holds. Cooking far longer than needed will soften the texture, so stay within a sensible window.
Why sous vide a burger instead of grilling it?
Control. A grill gives you a thin gradient from charred to raw and a guess at the centre, while sous vide makes the whole patty one even doneness with no grey band. The bigger reason is safety at lower temperatures: sous vide can pasteurise a pink burger by holding time and temperature together, so you get a juicy medium-rare result safely rather than relying on a high cook-through temperature. You still sear at the end for crust.
Do you sear a sous vide burger before or after?
After. Sous vide produces no browning because the water sits far below searing temperature, so the patty comes out cooked but pale. Pat it very dry, then sear it hard and fast in a smoking-hot cast-iron pan or on a hot grill to build the crust. Keep it short, well under a minute a side, so the heat does not push the inside past your target. See our guide on how to sear after sous vide.
Can you cook frozen patties sous vide?
Yes. You can drop frozen patties straight into the water bath; add roughly 50 percent more time so the centre reaches your set temperature and stays there long enough to pasteurise. Thickness still drives the timing. Treat the hold as time plus temperature together, the same as fresh, and confirm against a reputable chart for the exact temperature you are using.
