Instant Pot Corn on the Cob: The Ultimate Guide to Perfectly Cooked Sweetcorn Every Time
Forget boiling corn on the cob on the stovetop – the Instant Pot offers a faster, easier, and arguably tastier way to enjoy this summer favorite. This comprehensive guide will walk you through everything you need to know about cooking corn on the cob in your Instant Pot, from selecting the perfect ears to achieving that melt-in-your-mouth tenderness.
Why Choose Instant Pot Corn on the Cob?
The Instant Pot provides several advantages over traditional methods for cooking corn on the cob:
- Speed: Cooking time is significantly reduced, making it perfect for busy weeknights.
- Convenience: Minimal prep work is required, and cleanup is a breeze.
- Flavor Enhancement: The steam-cooking method in the Instant Pot helps to retain the corn’s natural sweetness and nutrients.
- Versatility: You can easily adjust cooking times to achieve your preferred level of tenderness.
- Uniform Cooking: Ensures all the kernels are cooked evenly, avoiding any undercooked or overcooked parts.
Selecting and Preparing the Corn
The key to delicious Instant Pot corn on the cob begins with selecting the right ears of corn. Look for ears with tight, green husks, and plump kernels. Avoid ears with dry or damaged husks, as these may indicate the corn is not as fresh.

Prepping the Corn for the Instant Pot:
- Remove the silks: Carefully peel back the husks and remove the silks from each ear of corn.
- Optional: Leave the husks on (for extra flavor and moisture): Some people prefer to leave the husks on for a more intense corn flavor and to retain moisture. If doing this, simply remove the silks.
- Wash the corn: Rinse the corn under cold water to remove any dirt or debris.
- Optional: Butter or oil the corn (for enhanced flavor): Before cooking, you can lightly brush the corn with melted butter or oil for added flavor. This step is entirely optional.
Cooking Corn on the Cob in the Instant Pot: Methods and Tips
There are several methods for cooking corn on the cob in your Instant Pot. We’ll explore two popular techniques:
Method 1: Steam Cooking (with minimal liquid)
This method yields tender, juicy corn with minimal fuss. It’s ideal for preserving the corn’s natural sweetness.
- Add 1 cup of water to the Instant Pot.
- Place a trivet inside the pot.
- Place the corn on the cob upright on the trivet.
- Close the lid and set the valve to sealing.
- Cook on high pressure for 3-5 minutes, depending on the desired tenderness (see variations below).
- Allow for a natural pressure release (NPR) for 10 minutes, then carefully quick release any remaining pressure.
- Carefully remove the corn using tongs or oven mitts.
Method 2: Steam Cooking (in Husks)
This method maintains extra moisture and adds a smoky depth of flavor.
- Add 1 cup of water to the Instant Pot.
- Place the corn on the cob (husks still on, silks removed) upright in the Instant Pot.
- Close the lid and set the valve to sealing.
- Cook on high pressure for 5-7 minutes.
- Allow for a natural pressure release (NPR) for 10 minutes, then carefully quick release any remaining pressure.
- Carefully remove the corn using tongs or oven mitts. Remove the husks and enjoy!
Cooking Time Variations:
The optimal cooking time depends on your preference for tenderness. Here’s a guideline:

- 3 minutes: Slightly crisp-tender corn.
- 5 minutes: Tender-crisp corn.
- 7 minutes: Very tender corn.
Always start with a shorter cooking time and add more time if needed. Overcooked corn can become mushy.
