Eden Kendall and Katie Garner celebrated Air Fryer Friday by making grilled cheese sandwiches in two different ways: one with butter and the other with mayonnaise. Using the air fryer, they achieved a crispy exterior without needing much oil, making it a healthier option. Eden pointed out how great the air fryer is for this classic dish, while Katie shared how mayonnaise can add a unique flavor. Both sandwiches turned out delicious, encouraging viewers to try their own grilled cheese creations at home. To make the sandwiches, set the air fryer to 380 degrees and cook for 2-4 minutes per side.
