🥄 Equipment
Which air fryer? I use the Ninja Foodi MAX PRO Health Grill, Flat Plate and Air Fryer with 7 customisable cooking functions including grill, flat plate, air fry, roast, bake, reheat and dehydrate! It also comes with a digital cooking probe that precisely monitors your food’s temperature as it cooks!
What is an air fryer?
Air fryers are small(ish) kitchen appliances that operate like a convection oven—except in a smaller, more concentrated space.
The air is circulated at a high temperature and evenly around the food, which makes the food cook more quickly than in a conventional oven and helps give foods a crispy coating without the need for lots of oil and fat.
🔪 How to make a cheese toastie in Ninja Foodi air fryer
The recipe card with ingredient quantities and detailed instructions can be found at the bottom of the post
One: Mix together the mayonnaise, dijon mustard, and garlic powder, and then spread a thin layer on one side of each slice of bread.
Two: Turn the slices over and butter the other sides of each slice of bread.
Three: Turn one of the slices back over so the mayo side is facing you and pile the grated cheese onto it.
Four: Place the other slice of bread on top - mayo side down touching the cheese with the buttered side on the outside facing you.
Five: Air fry at 180c for 6 mins. Flip with tongs or a plastic spatula then air fryer for a further 4 minutes until golden and crispy.

💭 Expert tips
- The buttered sides of the bread should always be on the outside.
- To make a healthier lower fat air fryer grilled cheese use reduced-fat cheddar and a cooking oil spray rather than butter.
- Cheese slices can be used in place of the grated cheddar.
🍴 Serving suggestions
What to serve with an air fryer toasted sandwich? Here are a few ideas!
Soup - tomato, pumpkin, roasted swede soup, or parsnip soup all go well with grilled cheese.
Pizza fries or halloumi fries for a real cheese-fest experience!
Sweet potato fries or baked carrot fries.
Sliced pear or apples for a sweet crunch, or how about a fresh beetroot and goats cheese salad?
📖 Variations
- Use different cheeses - crumbled blue cheese, gouda, havarti, or mozzarella would work really well.
- Add a slice of ham for an air fryer cheese and ham toastie. Grilled bacon would also be a good option.
- Spread a layer of caramelised onion chutney underneath the grated cheese layer.
- How about some grilled peppers or artichokes?
- Up the veg and add sliced mushrooms or halved cherry tomatoes.

🥡 Storage
Air fryer grilled cheese is best eaten fresh, straight out of the air fryer.
Leftovers can be reheated in the air fryer for a few minutes.
