McDonald's makes major change to fan favourite Filet-O-Fish for first time in 50 years

The 'King of Fast Food', McDonald's, has upped its game by making a slight change to the iconic Filet-O-Fish burger.

Recently kissing goodbye to its McSpicy x Frank's Red Hot and Steakhouse Stack in favour of the all-new Big Arch burger - featuring two 100 percent British and Irish beef patties, white cheddar cheese slices, crispy onions, fresh onions, shredded lettuce, crunchy pickles, and secret Big Arch sauce - Maccies is known to shakeup its menu every so often.

However, the Filet-O-Fish was launched in the UK half a century ago and has cemented itself as a firm favourite among fast food fans - with some even getting into fights over it.

The unbeatable combination of breadcrumbed fish patty, cheese and tartare sauce has become a go-to for many, but it seems something was still missing.

That something was size, apparently, as it's now been revealed that a Double Filet-O-Fish is set to join the Maccies menu from Tuesday (1 July).

On the day of its release, customers ordering via the McDonald's app will be the beneficiaries of a discounted price.

It'll cost £2 instead of £5.29, which the pescatarian product comes to outside of the Everyday Value Meal deal.

This was cause for celebration on social media, while burger-obsessives even revived an old Facebook group dating back to 2012 named 'The Filet-O-Fish Facebook Society'.

The group has since been flooded with thousands of new members, as one user hailed it as the 'best sandwich going'.

"Ahhhh!! I'm soo happy!!!! Best news ever!!" read another post. "Going to order two Filet-O-Fish now and turn it into a Big Fish Mac, to celebrate! The 1st of July is too far away."

Earlier this month, ex-Maccies corporate chef Mike Haracz weighed in on the menu's 'healthiest' item.

In a TikTok video, Mike - who has over 330,000 followers - claimed that the 'most nutritional' food you can order originates from the breakfast lineup.

Asked by a fan to identify the product boasting 'lower calories, lower cholesterol, and lower saturated fat', he claimed 'most of the items on the menu have these things' yet one specific alteration to the classic Egg McMuffin makes it the ideal order for the health-conscious; get rid of the butter.

"You've got one egg, which is 70 calories, one slice of Canadian bacon, which is lean protein," Mike said.

"Yes, I want to keep a little cheese on there so it's got some kind of flavour, and then you have the English muffin, which I believe is the lowest calorie carrier that you have."

While Mike plied his trade in the US division of the restaurant franchise, which had butterless and cheeseless Egg McMuffins down as between 274-280 calories (originally 310), the UK numbers were even lower.

On this side of the Atlantic, an Egg and Cheese McMuffin is listed at 295 calories ordinarily, but taking the butter and cheese out puts it in the 230-280 range.

For alternative 'low calorie' options, the former Maccies worker recommended getting the Big Breakfast without pancakes.

He noted that while you can 'adjust the menu' with requests, most of them 'are probably not as tasty as what's on the menu currently'.

As for the 'magic' seasoning that goes into Maccies burgers, Mike has also confirmed the surprisingly simple ingredients.

"It's just salt and pepper, there's literally no other things in it," the ex-chef explained in another video.

He encouraged anyone who believed he was telling fibs to go and get the answer out of McDonald's itself through legal means, or by buying one of its burgers and getting it tested.

Mike claimed that to get the mixture just right, you'd use 86 percent salt and 14 percent pepper, and that if you were trying to measure it out then it came out at about a teaspoon each, since salt was much heavier than pepper.
