1-First Step: Gather and prep Collect all ingredients and tools. You will need 4 thick slices of white bread, 2 slices of thin-sliced sharp cheddar, 2 to 4 slices of a melty cheese, and butter or oil spray. Have toothpicks ready to secure the sandwiches if needed. Preheat your air fryer to 370 degrees. While it heats, lightly butter the outsides of each bread slice or spray them with oil.

2-Second Step: Assemble the sandwiches Place one slice of sharp cheddar on the inside of a bread slice, then add 2 to 4 slices of a melty cheese on top. If you like a stronger cheddar flavor, use 2 slices of sharp cheddar plus 2 slices of melty cheese; for a milder melt, stick with 1 slice cheddar and 1 to 2 melty slices. Top with the second slice of bread, making sure the buttered sides face out. Use a toothpick to secure the sandwich corners so it stays together during cooking.

3-Third Step: Arrange in the air fryer Place the sandwiches in the air fryer basket in a single layer, leaving space between them for air to circulate. Overcrowding will cause uneven browning. If your air fryer is small, cook one sandwich at a time or in separate batches.

4-Fourth Step: Cook at the right temperature and time Cook the sandwiches at 370 degrees for a total of 5 to 6 minutes. Flip once halfway through the cook time to get even browning on both sides. Check at the 5-minute mark: the bread should be golden and the cheese should be melting. If you like a deeper toast, add another minute, but watch closely to avoid burning.

5-Fifth Step: Finishing touches and serving Remove sandwiches from the air fryer and take out the toothpicks before serving. Let them rest for 30 to 60 seconds to let the cheese set slightly so it does not drip out when sliced. Cut diagonally for classic presentation and serve with your favorite dipping sauce or a cup of tomato soup.
