🥄 Equipment
You'll need an air fryer for this recipe and I use the Ninja Foodi Health Grill and Air Fryer*. It not only air fries food but also grills, bakes, and dehydrates too. It's a super useful kitchen gadget and one that I definitely wouldn't do without (* denotes affiliate link).
🔪 How to make 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, 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.
📖 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.

- 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.

What a great recipe! So excited to make toasted cheese sandwiches in the air fryer, and I love the idea of adding grilled peppers. Another variation my family likes is thinly sliced tomatoes. Thanks for another winner from Effortless Foodie!
