Food Creator Reveals The Secret To A Flavour-Packed Tuna Melt

Everyone loves a good toastie – especially when it’s loaded with melty cheese and packed with flavour.
Food content creator @whatwilly recently shared what he calls the “world’s best” tuna melt, and it’s not your standard tuna-and-mayo affair.
In his viral TikTok video, Willy claimed, “I can confidently say that I make one of the best tuna mayo mixes that exists.”
His version takes the classic up a notch with a mix of chopped spring onion, coriander, jalapeños, gherkins and sundried tomatoes – giving every bite a punchy, fresh twist.
The Three Condiments That Transform A Classic Toastie

While most people stick to mayonnaise for a tuna melt, Willy insists that there are “non-negotiable” extras that make all the difference.
His “condimental” trio – harissa, mustard and mayo – is the foundation of the perfect mix.
As he explained, “When going condimental these are my essentials: harissa; mustard, very important; mayo.”
According to him, mustard is what truly elevates the flavour, adding just the right amount of sharpness to balance the richness of the cheese.
Or, as he put it, “Mustard is essential in a tuna mayo. Every time I’ve not added mustard, the tuna mayo has not been as good.”
Simple Steps To Make A Golden, Cheesy Tuna Melt At Home

For those ready to recreate the viral toastie, the method is as simple as it is satisfying.
Mix together tuna, the trio of condiments, lemon zest and Willy’s choice of chopped vegetables before stirring in plenty of cheese.
Pile it high between two slices of white bread – both sides slathered with mayo – and add a layer of crisps for extra crunch.
Fry gently on each side until golden and melted to perfection. Once toasted, slice it open and watch the cheese ooze out.
As Willy’s fans might agree, this version of the tuna melt truly earns its “best in the world” title.
