Frequently Asked Questions
Which cheeses melt best for this?
A mix like gouda, cheddar and maasdam gives stretch, sharpness and a smooth melt. Any good melting cheeses work; avoid hard, dry ones that turn oily.
How do I slice the onions into ribbons?
Run a vegetable peeler down the onion (spear it on a fork for grip) to make thin ribbons that go soft and sweet quickly as they cook.
Oven instead of air fryer?
Yes — bake covered at 200°C for about 25 minutes, stir, then uncovered 10 more until golden. Crisp the bacon separately and crumble on top.
