Overview
Ribeye and strip steaks are premium beef cuts with rich marbling that makes them ideal for sous vide cooking. The precise temperature control allows you to achieve perfect edge-to-edge doneness without the grey bands or overcooking that plague traditional high-heat methods. These thick steaks (typically one to two inches) benefit enormously from the water bath's gentle, even heat distribution, which renders intramuscular fat beautifully while keeping the meat tender throughout. After the bath, a quick high-heat sear creates the flavorful crust that defines a great steakhouse experience.
Core Time & Temperature
| Doneness | Temperature | Time | Max Time |
|---|---|---|---|
| Rare | 120°–128°F | 1–3 h | 4 h |
| Medium Rare | 129°–134°F | 1 h 30 min–4 h | 4 h |
| Medium | 135°–144°F | 2–4 h | 4 h |
Cooking time depends on thickness, not weight. Measure at the thickest part.
Food Safety Notes
Cooking time depends on thickness, not weight. Measure at the thickest part. For beef cooked below 145°F / 63°C, pasteurization occurs through sustained heat over time. At 129°–134°F / 57°C (medium-rare), hold for at least ninety minutes to achieve pasteurization. Always sear the exterior in a ripping-hot pan or grill to eliminate surface pathogens. Serve immediately. USDA recommends 145°F / 63°C with a three-minute rest for instant kill, but sous vide's time-temperature control provides equivalent safety at lower temperatures.

Prep & Bagging
- Dry brine with kosher salt one hour before bagging (or up to overnight in refrigerator)
- Pat surface completely dry with paper towels
- Season with freshly cracked black pepper and optional aromatics (thyme sprigs, crushed garlic)
- Vacuum seal or use zip-top bag with water displacement method
- If bags float, weigh them down with a heavy spoon or clip them to the side of the vessel
Finishing & Searing
- Remove steak from bag and pat completely dry with paper towels
- For best crust, chill steak briefly in freezer (five to ten minutes) to prevent overcooking during sear
- Heat cast iron or carbon steel pan over highest heat until smoking
- Add high smoke-point oil (avocado, grapeseed, or clarified butter)
- Sear forty-five seconds per side without moving the steak
- Add butter, garlic, and thyme for final thirty seconds, basting continuously
- Rest three to five minutes before slicing
