Ingredients and substitutions
- Corn - Depending on the size of your slow cooker and corn, you'll need about 6 to 8 corn cobs for this recipe. I fit 8 corn cobs, ends trimmed, into a 6-quart slow cooker.
- Water - You'll need to add a bit of water to the slow cooker to steam the corn and prevent burning at the bottom.
- Butter - Unsalted or salted butter works in this recipe. If using salted butter, you'll want to cut the listed salt in half.
- Seasoning - Salt, pepper, fresh chives, and garlic powder add mild, savory flavor to the butter. Fresh chives could be substituted with other fresh herbs like basil or parsley.

Tips and tricks
Check your slow cooker size - I fit eight medium sized corn cobs, ends trimmed, into a 6-quart oval slow cooker. Make sure the slow cooker isn't overfilled - the lid needs to fit flush with the top (no gaps) for proper cooking. At the same time, a slow cooker shouldn't be underfilled. Fill at least half to three-quarters full for best results.
How to tell when corn is done - Corn on the cob should look bright (the yellow color will intensify slightly), juicy, and tender. Corn cooked too long will look soggy and sometimes tough.
Softened butter - Bring your butter spread to room temperature 30 minutes before serving for easy spreading.
