How to Make Air Fryer French Onion Grilled Cheese

Start by spread butter on the bread and then place it down onto the air fryer basket. Top with the fried onions and sprinkle some Gruyere cheese on top.

Butter the top of the bread, and then place it on the sandwich. Set the temperature to 360 degrees F for 3-5 minutes. Then flip the sandwich and air fry for another 3-5 minutes, until the sandwich is toasted on both sides.

Can You Use Mayonnaise To Replace Butter?
Butter really gives this grilled cheese incredible flavor, espcially when mixed with the fried onoins. But, if you prefer not, go right ahead and reach for may or a mayo replacement. Many people love the slight change in flavor the mayo gives the grilled cheese. It isn’t a huge difference but it is delicious.
Can I Add Meat To The Sandwich
Want to transform your grilled cheese into a grilled ham and cheese? Or you might want to use up some leftover turkey from the holidays. Go ahead and pile on any of your favorite meats for added flavor to your sandwich.
Does Grilled Cheese Store Well
Unfortunately, no. You will find this sandwich is best served fresh and warm. Otherwise, your sandwich will lose the crispy texture you know and love from this sandwich.
I recommend making these when you want to eat them.
