Preheat the air fryer. Preheat the air fryer to 360°F.
Make the garlic butter sauce. In a small bowl, stir together the ghee or butter, olive oil, salt, garlic powder, and black pepper until smooth.
Start with the frozen corn. Lightly spray the air fryer basket with olive oil spray. Place the frozen corn cobs in the basket in a single layer, with a little space between each cob if possible.
Air fry to thaw and warm through. Air fry at 360°F for 10 minutes. This first stage helps the frozen corn thaw and heat through before adding the butter sauce.
Brush with garlic butter. Open the basket and carefully brush the corn on all sides with some of the garlic butter sauce. Save the extra sauce for serving.
Finish at higher heat. Increase the air fryer temperature to 400°F and air fry for 3 minutes, or until the corn is hot, tender, and lightly glossy.
Finish and serve. Transfer the corn to a serving plate. Brush with the remaining garlic butter sauce, then sprinkle with parmesan cheese and chopped parsley. Serve warm with lime wedges on the side
Notes
This recipe is for frozen corn on the cob cooked straight from the freezer. No thawing needed.
I use half-size frozen corn cobs. For larger cobs, add 1–3 more minutes as needed.
For fresh corn cobs, air fry at 380°F for 12 to 15 minutes. Brush the corn with the garlic butter sauce before adding it to the air fryer basket.
Store leftovers in an airtight container in the fridge for up to 4 days. Reheat in the air fryer, oven, or microwave until warm.
I don’t recommend freezing cooked corn again because the texture can turn softer and watery after thawing.
