Add all tuna salad ingredients to a bowl and stir until combined. More details and full recipe for Lazy No-Chop Tuna Salad here! You can also use your own tuna salad recipe.

First, cover one side of bread with the mayo or room temp butter. Place that piece of bread into the air fryer, mayo side down. Next, put the cheese slices on the bread, taking care that the cheese doesn’t go over the edges of the bread. Add 1/2 cup of tuna salad on top of the cheese and use a spoon to push it out to each edge of the bread. Finally, take the last pieces of bread and coat one side in mayonnaise, just like the other side. Add that piece of bread to the top of the sandwich, mayo side up.

Shut the air fryer basket and set the air fryer to cook at 380F for 8 minutes, flipping the sandwich halfway through. The tuna melt is done when you see melty cheese and golden brown edges to your preference! Remove from air fryer and cut in half on a cutting board. Repeat for as many tuna melts as you need. I recommend cooking only one tuna melt at a time if you’re using the basket style air fryer.
