Sous Vide Steak FAQ
What temperature should I use for sous vide steak?
Pick your doneness and commit. These are good, real-world targets for tender steaks:
- Rare: 125°F to 128°F
- Medium-rare: 129°F to 134°F (my sweet spot is 131°F for strip and filet mignon, 133°F to 137°F for ribeye if you want better fat rendering)
- Medium: 135°F to 144°F
- Medium-well: 145°F to 155°F
Food safety note: Safety is time and temperature, plus good handling. For most healthy adults using fresh whole-muscle steak, 129°F and up is a common sous vide range, but pasteurization depends on how long the center is held at temperature. If you are pregnant, immunocompromised, cooking for someone high-risk, or you want pasteurized steak, use a reputable sous vide time and temperature table and hold long enough at your chosen temperature.
How long should I sous vide steak?
For 1 to 1.5 inch steaks: 1 to 2 hours. For 2 inch steaks: 2 to 3 hours.
You can often go a bit longer without disaster, but texture is cut-dependent. Filet mignon can start to feel extra-soft sooner; ribeye and strip usually tolerate more time. As a general rule for tender cuts, try to stay within about 4 hours total in the bath.
Do I season before or after sous vide?
Season before so the salt has time to work its way in. Then taste after searing. If it needs a pinch of flaky salt, that is not failure, that is finishing.
Dry brine option: If you want to look like you really planned ahead, salt the steaks and refrigerate uncovered for 1 to 24 hours. Then bag and cook. Better seasoning, better crust potential.
Should I put butter in the bag?
You can, but it is not necessary. Many cooks prefer no butter in the bag because butter can mute the beefy flavor. I use butter at the end, in the pan, where it can brown and do its dramatic little performance.
How do I get a better crust?
Dryness and heat. Pat the steak very dry, use a ripping hot pan, and keep the sear short.
If you want maximum crust insurance, chill the steak in the fridge for 10 minutes after the bath and before searing, uncovered. Drier surface, better browning.
How do I keep the bag from floating?
Air is the enemy. Seal well, then clip the bag to the side of the container, and add a sous vide weight (or a metal spoon) inside the bag if needed. If using a zip-top bag, keep the zipper above the waterline so it does not leak.
My pan sear sets off the smoke alarm. Help.
Use a high-smoke-point oil (avocado, grapeseed, canola), use just enough to lightly coat the pan, and turn on the vent fan before you start. A quick sear is your friend. If you have one, an outdoor burner is the ultimate smoke hack.
Is sous vide steak safe?
Yes, when you use proper time and temperature and keep the steak sealed and submerged. Use fresh steak, keep the bath at your target temperature, and do not leave it sitting out after cooking. If you want pasteurization-level certainty, follow a trusted sous vide time and temperature chart for your steak thickness.
