This Air Fryer Welsh Rarebit recipe is a simple version of a classic British delicacy. There's no need to make a sauce first or melt the cheese before adding to the bread. Simply mix the topping ingredients including the traditional flavours or mustard, Worcestershire sauce and ale along with a good mature cheddar and away you go!
If your air fryer requires pre-heating, start this setting now.
Measure around 150g Grated Cheddar Cheeseinto a bowl. Sprinkle with 2 tsp Plain Flour and toss to coat the cheese strands.
Separate 1 Egg and set aside the white for another time. Add the yolk to the cheese along with 4 tbsp Ale, 1 tsp Worcestershire Sauce and 1 tsp English Mustard Powder.
Mix everything together really well.
Take 2 Slices Bread and put in the air fryer basket.
Air-fry for 3 minutes at 200c/390f.
Remove the lightly toasted bread from the air fryer and flip it over onto a board. Spread around 2 tsp Salted Butter onto the toast.
Pile the cheese mixture onto the slices of buttered toast.
Gently spread out the mixture to totally cover the slices - aim for an even layer rather than a mouth in the centre - this will help even cooking.
Carefully place the toast back into the air fryer.
Air fry for 8 minutes at 170c/340f until the cheese is melted and bubbling. This is a lower and longer cook than regular cheese on toast - this is to make sure the thick layer of cheese melts all the way through and the egg/ale/flour paste has time to fully cook.
Serve hot!
Notes
The air fryer version of this recipe is tested in a Cosori Lite (CAF-LI401S) with a 3.8 litre capacity. The square(ish) shaped basket is 21cm x 21cm and 24cm on the diagonal.
Not all models advise preheating is required. Please follow the recommended instructions for your model. Mine has a specific preheat setting which is 4 minutes at 205c.
For this recipe, I can just fit two thick 60g slices of bread in the basket at a time. This gives just enough room to allow air to circulate. But my bread happened to be long and thin so it fitted well. You may need to check the fit depending on what type of bread you're using.
As all air fryer models are a little different, you may find that you can fit more or less in at a time. Some models include stacking shelves which will increase capacity.
Required cooking times and temperatures can also vary between models and brands. If you know that your air fryer runs a little hotter than most recipes suggest, use a lower temperature. And vice versa. Equally if you find that food cooks more quickly in your machine than instructions usually state, reduce the cooking time (or check it earlier) and vice versa.
