Sous vide potatoes: locked time, temperature, and scope
Anova’s Sous Vide Butter-Poached Potatoes recipe specifies 1 lb of small Yukon Gold potatoes cut in half or fingerlings at 190°F (87°C) for 1 hour. It is a recipe-specific cooking path, not a chart for every potato shape or a general food-safety process. Plan to serve this batch immediately after opening the bag.
That narrow scope matters more than a broad “potatoes” label. Geometry changes how much potato sits between bath and center, while the available recipe does not establish replacement times for other cuts. Keep the documented time-and-temperature pair intact instead of borrowing the temperature and adding an unverified amount of time.
Use this shape and size evidence gate first
This compatibility table is the decision tool for this guide. It separates what the cited recipe supports from cases that need their own source or belong to another search intent.
| Potato form | Decision | What to do |
|---|---|---|
| Fresh small Yukon Gold potatoes, cut in half | Use locked schedule | Use 190°F (87°C) for 1 hour for 1 lb; serve immediately after opening the bag. |
| Fresh fingerling potatoes | Use locked schedule | Use 190°F (87°C) for 1 hour for 1 lb; serve immediately after opening the bag. |
| Large whole potatoes; wedges; coins; dice; slabs | New evidence required | Do not transfer this schedule or estimate an extension. Find guidance matching your exact shape and load. |
| Frozen potatoes; stacked or crowded batches | New evidence required | Starting state and load limits are outside available recipe evidence. |
| Mashed potatoes; sweet potatoes; fries or chips | Separate intent | Use a separate, evidence-matched guide. This article does not cover these preparations. |
Do not transfer this potato schedule to another vegetable. Use the separate source-matched guides for sous vide asparagus and sous vide corn on the cob when those ingredients are the actual cook.
The table does not predict failure for excluded forms. It prevents false precision: no matching source here establishes how long a large whole potato, a wedge, or a frozen potato needs at this temperature.
Prepare potatoes and choose documented bag paths
Start with fresh potatoes that fit the gate: 1 lb of small Yukon Gold halves or fingerlings. Before cutting, wash them under running water. FDA advises against soap and commercial produce washes; washing can reduce bacteria but does not eliminate it. FDA produce guidance supplies this produce-handling step, not a sous vide lethality claim.
For packaging, Anova’s recipe names two routes: a zipper-lock bag using water immersion or a vacuum-seal bag. This establishes options used by that recipe; it does not establish a preferred bag brand, bag material, seal method, or capacity limit. Readers who need a separate walkthrough can see how to sous vide without a vacuum sealer.
Cook, check scope, and serve
- Set water bath to 190°F (87°C).
- Cook 1 lb of fresh small Yukon Gold halves or fingerlings for 1 hour, following the cited recipe’s bag path.
- Open bag and serve immediately.
This guide does not require a skillet, oven, or other finishing step because available evidence does not establish one. If a finish matters to your dish, choose a separately supported recipe rather than treating an optional finish as part of this documented schedule.
When texture is not what you expected
Potatoes are firm in the center
Stop before adding time by default. Check whether potatoes were large whole potatoes, a different cut, frozen, more than 1 lb, or crowded in layers. Any of those changes moves batch outside evidence gate. Find shape- and load-matched guidance before changing schedule.
Texture varies from piece to piece
Mixed sizes or a crowded bag can explain uneven results, but this article has no measured source that sets an allowable size range or layer limit. Treat uneven texture as a prompt to return to one eligible shape and 1 lb, not proof that a universal time increase will solve it.
Bag leaks or loses its seal
No controlling source in this guide supports a restart, discard, or recovery protocol. Do not infer one from recipe timing. Resolve bag failure with guidance that addresses your equipment and situation.
Important limits: immediate service, not storage guidance
190°F (87°C) for 1 hour is not presented here as a universal pasteurization, cook-chill, storage, or reheating process. Anova’s cited workflow is for immediate service. USDA does provide general cooked-potato leftover guidance, including 3 to 4 refrigerator days, but that guidance does not validate sealed-bag sous vide cooling or storage. Keep storage and reheating outside this recipe unless you have separate guidance for those steps. USDA’s cooked-potato storage answer is general leftover guidance, not validation for this method.
Bottom line
For eligible fresh small Yukon Gold halves or fingerlings, use Anova’s 190°F (87°C), 1-hour, 1-lb path and serve right away. For any different potato form, starting state, batch arrangement, storage plan, or finish, pause instead of improvising a time: that is new evidence territory.
