Assemble the Toasties Bread: Lay out the slices of bread on a clean surface.
Butter: Spread a thin layer of butter on one side of each slice of bread.
Cheese and Onion Filling: On the unbuttered side of two slices, sprinkle half of the grated cheese. Add the chopped onions evenly over the cheese. Season with a pinch of salt and black pepper. Optionally, you can spread a thin layer of mayonnaise on the other two slices of bread for extra creaminess. Top Layer: Place the remaining slices of bread on top of the cheese and onion mixture, buttered side facing out.
Preheat the Air Fryer. Preheat your air fryer to 180°C (350°F) for about 3 minutes.
Cook the Toasties. Place the assembled toasties in the air fryer basket. Depending on the size of your air fryer, you may need to cook them one at a time.
Cook the toasties at 180°C (350°F) for 5-7 minutes, flipping halfway through. Cook until the bread is golden brown and crispy, and the cheese is melted.
Serve. Remove the toasties from the air fryer and let them cool for a minute before slicing. Serve immediately and enjoy your delicious Cheese and Onion Toastie!
Tips: Cheese Variations: You can use other types of cheese like mozzarella, gouda, or a mix of cheeses for different flavors. Add-Ons: Feel free to add extras like sliced tomatoes, ham, or a sprinkle of herbs for added flavor.
Air Fryer Settings: Air fryer models may vary, so keep an eye on the toasties to avoid burning
