Sous Vide Beef Liver
Silky, not grainy — the method that actually makes liver good
Liver's bad reputation mostly comes from overcooking — it goes grainy and bitter fast on a hot pan. Sous vide holds it at the exact temperature where it's pasteurized but still tender. For Pack Stew, you'll puree it into the base. For human plates, a fast sear after brings it to life.
Temperature Guide
| Texture | Temp (°F) | Temp (°C) | Time |
|---|---|---|---|
| Silky / slightly pink | 140°F | 60°C | 45–60 min |
| Fully cooked, tender | 149°F | 65°C | 45–60 min |
| Traditional firm texture | 158°F | 70°C | 30–45 min |
✦ Recommended: 140–145°F for 45–60 min
Steps
- 1
Milk soak (optional but recommended)
Soak liver in milk for 30 minutes to 2 hours before cooking. This mellows any bitterness. Rinse and pat dry.
- 2
Bag
For Pack Stew use: bag plain (no seasoning). For human plates: add salt, pepper, a smashed garlic clove, fresh thyme, and a small pat of butter. Seal.

Sous vide
Cook at 140°F for 45–60 minutes.
- 4
For Pack Stew base
Remove from bag and puree with bone broth until smooth. Fold into your sweet potato / squash base.
- 5
For human plates: sear
Get a cast iron screaming hot. Sear for 30–45 seconds per side — you want color without cooking further. The bag juices can be reduced quickly in the pan as a drizzle.
Notes
Slice thin before or after cooking for more even results. Liver goes from silky to grainy quickly with excess heat — don't overdo the sear.
