Ingredients For Air Fryer Cheese Toastie

You only need a few simple ingredients.

• 2 slices thick white bread
• butter
• mayonnaise
• Dijon mustard
• grated mature Cheddar cheese

Ingredient Notes And Easy Swaps

Bread

Thick white bread works really well because it crisps up beautifully and holds the cheese filling.

You could also use:

• sourdough
• farmhouse bread
• seeded bread
• wholemeal bread

Cheese

Mature Cheddar is our favourite because it melts well and has plenty of flavour.

You could also try:

• Red Leicester
• Gouda
• Havarti
• mozzarella
• cheese slices
• a mix of cheeses

Butter

Butter on the outside of the bread helps the toastie turn golden, crisp and properly delicious.

Mayonnaise And Dijon Mustard

The mayo and mustard mixture goes inside the sandwich. It adds flavour and helps the toastie stick together as it cooks.

If you don’t like mustard, leave it out or swap for a spoonful of caramelised onion chutney.

Equipment Needed

You’ll need:

• air fryer
• bread board
• cheese grater
• butter knife
• small bowl
• teaspoon
• tablespoon
• silicone tongs

How To Make A Cheese Toastie In The Air Fryer

Step 1 – Butter The Bread

Take one slice of bread and spread butter onto one side.

Place it butter side down on the board.

Step 2 – Mix The Mayo And Mustard

Mix the mayonnaise and Dijon mustard together in a small bowl.

Spread half of the mixture over the top side of the bread.

Step 3 – Add The Cheese

Add the grated cheese and spread it evenly right to the edges.

This helps every bite taste properly cheesy.

Step 4 – Add The Top Slice

Spread the remaining mustard mayo onto the second slice of bread.

Place it on top of the cheese, mayo side down.

Press the sandwich together firmly with your hand, then butter the top slice of bread.

Step 5 – Air Fry The Cheese Toastie

Place the sandwich into the air fryer basket.

Cook at 200°C for 6 to 8 minutes, flipping after 3 to 4 minutes.

The toastie is ready when the bread is golden brown and crisp and the cheese has melted inside.

Step 6 – Slice And Serve

Remove the toastie carefully using tongs.

Slice into halves or quarters and serve straight away while the cheese is still hot and melty.

Best Tips For The Perfect Air Fryer Cheese Toastie

Don’t Skip The Mayo

The mayo helps the sandwich hold together and adds a richer flavour.

Use Grated Cheese

Grated cheese melts more evenly than thick slices.

Press The Sandwich Together

A good press before cooking helps the toastie stay together in the air fryer.

Flip Halfway Through

This helps both sides turn golden and crisp.

Check From 5 Minutes

Air fryers can cook slightly differently, so check early the first time you make it.

Be Generous With The Cheese

You want enough cheese for that proper melty middle.

What To Serve With Air Fryer Cheese Toastie

A cheese toastie is great on its own, but it’s even better with a side.

Try it with:

• tomato soup
• baked beans
• apple coleslaw
• potato salad
• tomato and cucumber salad
• avocado salad
• chips or fries

Easy Cheese Toastie Variations

Cheese And Ham Toastie

Add sliced ham before cooking.

Cheese And Bacon Toastie

Add cooked crispy bacon.

Cheese And Tomato Toastie

Add thinly sliced tomato, but don’t use too much or the bread can go soggy.

Cheese And Chutney Toastie

Add caramelised onion chutney or tomato chutney.

Cheese And Spinach Toastie

Add a small handful of spinach with the cheese.

Air Fryer Toastie Troubleshooting

My Toastie Is Not Crispy

Cook it for another minute or two and make sure the bread is buttered on the outside.

The Cheese Hasn’t Melted

The cheese may be too thickly sliced. Grated cheese melts faster and more evenly.

The Sandwich Is Opening In The Air Fryer

Press it down firmly before cooking. You can also secure it with a cocktail stick if needed.

The Bread Is Browning Too Fast

Reduce the cooking time slightly or check earlier next time.
