The ideal time to boil corn on the cob is generally about 5 minutes once the water has returned to a boil after adding the corn. This timing yields tender, juicy kernels that are not overcooked. Some sources suggest a range of 3 to 7 minutes depending on personal preference, with shorter times for crisper corn and slightly longer for more tender corn. It's important to bring the water to a boil first (without the corn), add the corn, bring the water back to a boil, then simmer for 5 minutes uncovered, occasionally stirring or moving the cobs for even cooking. Overboiling beyond 5-7 minutes can make the corn too soft. Summary of boiling times from sources:
- 5 minutes is the sweet spot for tender, juicy corn
- Some boil for 3 minutes for crisper corn or up to 7 minutes for softer corn
- One source mentions boiling then turning off heat to let it sit covered for about 10 minutes
- Avoid boiling for as long as 20 or 30 minutes to prevent overly soft corn
Thus, for classic boiling, 5 minutes after the water returns to boiling is recommended for perfect corn on the cob.
