Overview
Corn on the cob cooked sous vide is a game-changer for summer dinners and barbecues. Unlike traditional boiling which leaches flavor and nutrients into the water, sous vide locks in corn's natural sweetness and creates incredibly tender, juicy kernels that pop with flavor. The ideal temperature is 183°–185°F / 84°–85°C, which fully cooks the corn while preserving its bright color and sweet taste. The vacuum-sealed environment means you can infuse corn with butter, herbs, and seasonings that penetrate deeply during cooking. Whether you're making classic butter-and-salt corn or Mexican elote-style preparations, sous vide delivers consistent, delicious results with zero monitoring required.
Core Time & Temperature
| Doneness | Temperature | Time | Max Time |
|---|---|---|---|
| Tender Sweet | 183°–185°F | 30–40 min | 1 h |
| Traditional | 185°–190°F | 30–40 min | 1 h |
| Very Soft | 190°–194°F | 30–40 min | 1 h |
Cooking time is consistent for all corn sizes. Fresh, in-season corn works best.
Food Safety Notes
Corn is safe to eat when fully cooked through. At 183°F / 84°C and above, corn reaches proper doneness very quickly. No specific food safety concerns exist for corn cooked sous vide. Always refrigerate cooked corn promptly if not serving immediately and consume within three to four days. Handle produce safely and keep bags below 183°F sealed tightly to avoid botulism risk. Chill leftovers quickly if not serving immediately.
