Overview
Tuna is best when it stays ruby and tender, which is why timing and temperature matter so much. Sous vide lets you gently warm the center for sashimi-like texture, then add a fast sear for a crust without blowing past medium-rare. Use this guide to dial in everything from poke-ready cubes to seared steaks for salads and rice bowls.
Core Time & Temperature
| Doneness | Temperature | Time | Max Time |
|---|---|---|---|
| Seared Rare | 105°–110°F | 30 min | 60 min |
| Warm Center | 115°–120°F | 40 min | 90 min |
| Firm | 125°F | 45 min | 2 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. Note: For sashimi-style temperatures below 130°F / 54°C, use sushi-grade tuna frozen to FDA standards (-4°F / -20°C for 7 days or -31°F / -35°C for 15 h) to eliminate parasites. Follow safe cooking practices and USDA guidelines for internal temperatures. Use the freshest seafood available, keep everything chilled before cooking, and serve lower-than-130°F preparations immediately.

Texture Profiles
- 105°–110°FSeared Rare
- Sashimi-style center, just warm enough to take a sear.
- 115°–120°FWarm Center
- A little more opaque but still tender.
- 125°FFirm
- Fully cooked tuna for salads or sandwiches.
Prep & Bagging
- Season with salt and desired spices
- Add aromatics if desired (garlic, herbs, citrus)
- Vacuum seal or use zip-top bag with water displacement method
- Ensure food is fully submerged during cooking
Finishing & Searing
- Remove from bag and pat completely dry with paper towels
- Optional: chill briefly in freezer (5–10 min) to prevent overcooking during sear
- Heat pan over high heat until smoking
- Add high smoke-point oil
- Sear 45–60 sec per side without moving
- Rest briefly before serving
