Mix the butter with the oil, garlic, garlic powder and herbs, and season with salt and pepper.A pinch of chilli flakes in the butter is also really good.
Halve the baguette or ciabatta, and cut it to size so it fits in your air fryer.
Spread the bread with the garlic butter, then top it with the two cheeses.
Place the pieces in the basket of your air fryer and give them about 6 minutes at 200°C, or until the cheese is golden and the bread is crisp.I don't preheat my air fryer, - but they all heat differently, so do what you normally do.The garlic bread can also be made in the oven, - about 12 minutes at 200°C.
Sprinkle with finely chopped parsley and chilli flakes, if using, before serving.
