Layer one layer of frozen french fries in the air fryer basket.
Air fry these french fries at 200C (390F) for 12 minutes. Give a shake at least once during the cooking time to avoid the fries sticking to the basket.
Once your chips have been air frying for 12 minutes they'll be beginning to crisp up nicely and then you can layer on your toppings.
Layer on the cooked beef mince, chopped red pepper, chopped cooked bacon and cheese sauce.
Air fry at 200C (390F) for another 2-3 minutes.
You can use homemade nacho cheese sauce or the squeezy bottled cheese sauce that many UK supermarkets sell.
