Irish Cheese Toasties (Cheese on Toast) – Easy Classic Recipe

 

If you’re craving something quick, comforting, and irresistibly cheesy, these Irish Cheese Toasties are about to become your new favorite anytime snack. Unlike a traditional grilled cheese, this Irish version is served open‑faced and topped with a rich mixture of eggs, sharp cheddar, Dijon mustard, and Worcestershire sauce, which bakes into a beautifully puffy, golden, savory topping that’s completely addictive. 

It’s a classic UK comfort food — simple, satisfying, and ready in under 20 minutes — perfect for breakfast, lunch, or a cozy late‑night bite. Whether you use brown bread, white, or potato bread, every slice comes out with crispy edges and a soft, cheesy center that hits all the right notes. If you love easy, nostalgic recipes with big flavor, this Irish Cheese Toastie is one you’ll want to make again and again.

 

I am always looking for a nice toastie recipe.  A toastie is what they would call a type of grilled sandwich in the U.K. They can either be open faced and grilled/toasted on the bottoms, or like a toasted sandwich, bun, etc.  toasted on both sides.  They make a lovely lunch or light supper when served with a cup or bowl of soup.

I picked up some nice Irish cheese at the shops to use in this sandwich. White cheddar of course. In the U.K. most cheeses are white, except for Rd Leicester which is orange in color. White is the natural color of most cheeses, unless dyed. 

I wanted to make Eileen and I a simple lunch/supper of a cheese toastie and came across this recipe on this page.  I am not sure if the word Irish refers to the type of cheese used, or the place the recipe hails from. I tend to think it is the type of cheese used. In either case it makes for a really simple and delicious sandwich! I did take the liberty of cutting the recipe down to serve only two people.

We enjoyed these with a hot mug of tomato soup on the side. You could also serve them with some veggie sticks or a salad. They are delicious any which way.  I always like to add a dab of butter to the top of my tomato soup.  It is really lovely this way.  I know  . . .  I am a bit of a glutton and like to bring out the best flavors in anything I cook and eat!  These made for a really lovely lunch.

 

INGREDIENTS NEEDED

TO MAKE

AN IRISH CHEESE TOASTIE 

There is nothing too extraordinary to use in this. DO try to find a good sharp cheddar for it, and a nice country style bread. From the above photograph you can see just how nice and toasty the buttered bottom gets!

• 2 thick slices of bread (brown, potato, white or whole grain)
• 1 TBS softened butter
• 1 large egg, beaten
• 3/4 tsp of English or Dijon mustard
• 3/4 tsp Worcestershire sauce
• 3 ounces (3/4 cup/85g) grated Irish cheddar cheese (Kerry Gold Dubliner is nice)
• 1/4 tsp freshly ground black pepper
• 2 tsp finely chopped chives to garnish

 

NOTES ON INGREDIENTS

 

• I used a farmhouse white bread that was about 1/2 inch thick and quite sturdy.
• I used salted butter.
• I buy my eggs at a local chicken farm. They are free range and organic.
• English mustard is quite hot. If you are not a fan of heat then use Dijon which has a much milder and mellow heat.
• Worcestershire sauce can be found in the condiments section of most shops.
• If you cannot find an Irish cheddar, then use a good strong English one.  Sharp cheese is preferable as is white cheddar.
• I grind my own pepper.

 

HOW TO MAKE

AN

IRISH CHEESE TOASTIE

These are really quite simple to make. Do make sure not to overcook them. Mine did get a touch brown, but they are better when taken out just shy of this.

1. Preheat the oven to 425*F/230*C/ gas mark 7. Line a small baking tray with either aluminum foil or baking paper. Set aside. (This makes for easy cleanup.)
2. Butter both slices of bread on the bottom side and place onto the prepared baking sheet, buttered side down. (You only need to butter the bottom side. This will get nice and toasty in the oven.)
3. Grate your cheddar cheese into a bowl. (I used the large holes on the box grater.)
4. Whisk together the egg, mustard, pepper and Worcestershire sauce until well combined. Stir this mixture into the grated cheese, again combining well. (Mix everything well together.)
5. Divide the mixture between both slices of bread, popping it onto the top. Use a spatula to spread it out in an even layer. (Spread it out evenly. It is best spread right to the edge.)
6. Bake for 8 to 12 minutes in the preheated oven until the edges of the bread are golden and the center is puffy and melted. (Don't allow it to get overly brown.)
7. Remove from the oven. Sprinkle with the chives and serve immediately. (A nice mug of hot soup goes very well with this.)

 

HINTS AND TIPS

FOR MAKING AN IRISH CHEESE TOASTIE

✨Use good, sturdy bread for the best base. The recipe works with brown, potato, white, or multigrain bread, but sturdier slices hold the rich topping especially well.

✨Butter the bread properly — and on the right side. Butter the top of the bread first, then flip it so the buttered side faces down on the baking sheet. This ensures the underside crisps beautifully while the topping stays soft and puffy.

✨Whisk the egg mixture thoroughly. A well‑mixed blend of eggs, Dijon, and Worcestershire gives the topping its signature lift and savory depth. Whisking fully ensures even puffing and flavor in every bite.

✨Use freshly grated cheddar for the best melt. Aged Irish cheddar is traditional, but any sharp, well‑melting cheese works. Freshly grated cheese melts more evenly and gives that gorgeous golden top.

✨Bake until the center is puffed and the edges are golden. This visual cue is key: the topping should rise slightly in the middle, and the bread edges should be crisp and browned. That’s when you know it’s perfect.

✨Serve immediately for the best texture. These toasties are at their peak the moment they come out of the oven — crisp edges, soft centre, and beautifully melty cheese .

✨Make only what you’ll eat fresh. Toasties are best enjoyed right away, so feel free to halve or third the recipe if you’re cooking for one or two .

✨Use a spatula to lift them cleanly. The topping is soft and puffy — a spatula helps you transfer them neatly without tearing the bread

 

FREQUENTLY ASKED QUESTIONS 

CAN THESE BE MADE AHEAD OF TIME?

You can certainly make the cheese mixture up ahead of time and refrigerate it, covered, ready to spread onto your bread when you are ready to cook it. I wouldn't make it any more than 6 to 8 hours ahead of time. Let it come almost to room temperature before using.

WHAT TYPE OF BREAD IS BEST FOR THIS?

You will want to use a sturdy country style bread that will hold up to the toasting and the filling.  I used a white farmhouse loaf for mine. Thick and sturdy.

WHAT IS THE BEST KIND OF CHEESE TO USE?

I recommend a good Farmhouse or Irish sharp cheddar.  Kerry Dubliner is great, but any sharp white cheddar will do.  DO GRATE YOUR OWN CHEESE TO USE IN THIS SANDWICH.

CAN THIS BE MADE IN THE AIR FRYER?

Since this is a small batch recipe, the size is perfectly acceptable to make in an  air fryer which will hold two slices of bread comfortably in a single layer.  

MUST I USE ENGLISH MUSTARD?

English mustard has a lovely heat and color, but you can certainly use a Dijon in it's place. It won't be quite as spicy.

CAN MEAT BE ADDED TO THIS RECIPE?

Certainly you can added chopped bits of ham or bacon to the cheese mixture. You could also add a layer of ham or cooked rashers of bacon to the bread before you add the cheese topping.
