Fast food chains have a habit of releasing sandwiches so good they leave fans wanting more. These limited-time favourites often vanish just as they gain loyal followings, sparking online pleas and petitions for their comeback.
Some flavours are simply too good to stay gone – and these standout sandwiches deserve a permanent place on the menu.

1. McDonald's McRib
Every autumn, devoted fans start counting down the days until this saucy legend makes its comeback. The McRib features boneless pork slathered in tangy barbecue sauce, topped with onions and pickles on a soft bun.
Since 1981, McDonald's has turned this sandwich into a cult phenomenon by keeping it seasonal. Fans have even created online trackers to find locations still serving it.
Its limited availability creates massive hype, but wouldn't it be brilliant if you could satisfy that craving any day of the year?
2. KFC Double Down
Forget everything you know about sandwiches because this one ditches the bun entirely. Two crispy chicken fillets replace the bread, sandwiching bacon, cheese, and special sauce in between.
When KFC launched it in 2010, it caused an absolute stir amongst fast food fans and health critics alike. The audacious concept became a viral sensation, with people queuing up to try this bonkers creation.
Though it returns occasionally in select markets, making it permanent would satisfy those who crave its unapologetically indulgent approach to lunch.
3. McDonald's Chicken Katsu Wrap
Japanese flavours met British convenience when this wrap appeared on McDonald's menus. Crispy breaded chicken gets wrapped up with fresh lettuce and a sweet curry sauce that's absolutely moreish.
The katsu craze has swept across Britain's high streets, from fancy restaurants to Pret sandwiches. McDonald's version offered an affordable way to enjoy the trend without breaking the bank.
Its limited run left fans gutted when it disappeared, with many claiming it was the best thing McDonald's had done in years.
4. McDonald's Philly Cheese Stack
American comfort food crossed the pond when this beauty graced UK menus for a brief spell. Two beef patties come loaded with peppers, onions, and that signature cheese sauce that makes Philadelphia cheesesteaks legendary.
The combination of savoury beef and gooey cheese proved irresistible to British burger lovers. Its hearty portions and bold flavours made it stand out from the usual McDonald's lineup.
Bringing it back permanently would give fans a proper taste of Philly without needing a plane ticket.
5. Burger King Fiery Big Fish Sandwich
Not everyone wants beef or chicken, and this spicy fish option gave seafood fans something to celebrate. A crispy fish fillet gets topped with fiery sauce and fresh lettuce on a toasted bun.
Fish sandwiches often play second fiddle at burger chains, but this one brought proper heat and flavour. The spicy kick elevated it beyond boring Friday alternatives, making it genuinely exciting.
Keeping it on the menu permanently would show that Burger King values customers who fancy something different from the usual offerings.
6. Burger King Wagyu Burger
Wagyu beef typically costs a fortune at posh restaurants, so Burger King's affordable version caused quite a stir. Their Gourmet Kings range featured premium wagyu patties with fancy toppings that elevated the whole experience.
The rich, buttery flavour of wagyu made this burger taste miles above standard fast food fare. Pairing luxury ingredients with fast food convenience felt like having your cake and eating it too.
Making it permanent would let everyone enjoy a taste of the high life without emptying their wallets completely.
7. McDonald's Double Big Mac
Sometimes bigger really is better, and this monster took the iconic Big Mac to absolutely ridiculous proportions. Four beef patties instead of two, plus all the classic fixings including that special sauce everyone loves.
When it launched, fans with serious appetites rejoiced at finally having a Big Mac that could properly fill them up. The towering creation became an Instagram sensation, with people sharing photos of their ambitious attempts to finish it.
Keeping it permanent would satisfy those who've always found the regular Big Mac a bit lacking.
