So much so that he thinks the ‘problem in this country’ is people not using enough of it.
The celebrity chef has called for a kitchen cupboard staple to be 'banned' as he slammed the growing popularity of 'packet food' in Britain, reports The Manc.
Shunning a butter substitute that many people use every day as "horrendous", the former Saturday Kitchen host said that margarine was “two elements away from plastic".
Calling for British consumers to replace their margarine with full-fat butter, Martin said many don't know about the “hidden” ingredients in margarine.
Speaking to the Sunday Post, the chef said: “Margarine should be banned. It’s dreadful, dreadful stuff, it’s two elements away from plastic, it’s horrendous stuff.
"It’s the ready-made food, it’s the packet food, the hidden salt, hidden fat. That’s the problem in this country.”
He added that as a “farmer’s kid”, he preferred real butter, full-fat milk and cream, revealing that there was no semi-skimmed milk in his house growing up.
“That’s the problem in this country. It’s not the butter in a butter block or butter you put on your toast,” he said.
The chef, who has a restaurant in Manchester's 253 Casino, is well known and loved for his cookery shows on the BBC, ITV and Channel 4.
After a decade spent fronting BBC's Saturday Kitchen, he then moved across to ITV in 2017 to host his own show: James Martin's Saturday Morning.
His love of butter is well known, with Martin even releasing a book in 2021 called Butter: Comforting, Delicious, Versatile featuring over 130 recipes celebrating the ingredient.
The Yorkshireman puts butter on everything, including his roast potatoes, and as a child would make his own buttery lunchbox sandwiches with slathers of the good stuff, alongside mashed banana and a Cadbury flake.
The foodie-favourite restaurant and bar is now under new management.
The eagle-eyed amongst you may have noticed that Woodside has sadly been closed for a few months.
We certainly have, and ever since December we've had a Woodside Sunday roast-shaped hole in our hearts that's been gasping for one of their glorious Marmite glazed parsnips.
But luckily, it has now been confirmed that Woodside isn't going anywhere as Superfriendz, the team behind Headrow House, Belgrave and many other top Leeds spots will be taking over. Hallelujah.

Woodside opened at the end of 2024 from the owners of The Brunswick and The Melbourne.
Labelling itself as a 'neighbourhood eatery and bar', Woodside quickly became a favourite amongst Leeds foodies and was known for its smoked meats, great cocktails and stellar Sunday roasts (do I need to talk about the parsnips again).
The menu was fresh and innovative, with oysters topped with kiwi granita and an incredibly garish banana split standing out as highlights.

We hope that the new management continues to maintain Woodside's brilliance, but mainly we're just so glad that it's sticking around.
Superfriendz take care of a whole host of spots in the city, including proper Leeds favourites Headrow House, Belgrave Music Hall and Waterlane Boathouse.
Announcing the news to Instagram, Woodside said: "After a longer-than-expected winter break, Woodside is back and will reopen on Thursday 19th March!
"Your favourite neighbourhood bar and eatery returns with the same warm welcome, but an all new management team.
"We can’t wait to see you so keep your eyes on our socials for news on great food and drinks, big screen sports, quizzes and more.
"We’d also like to thank Sam and the original team for all the hard work that went into setting-up the venue. We hope we can do it justice."
A new female-founded business has opened in Leeds and it’s a trinket-lover’s paradise
Clementine Hall
Lisa Angel has just opened inside the Victoria Gate and it’s an Aladdin’s Cave full of jewellery, prints, gifts and everything in between.
The best part? It’s a female-founded brand that has chosen our wonderful city for their first Yorkshire site. We absolutely don't blame them.
Founded in 2004 by Lisa hand making jewellery which she sold at craft fairs local to her Norfolk home, the business has gone from strength to strength every since.
The brand is now a recognised part of the British high street landscape, boasting seven other stores across Norfolk, Suffolk, and the Midlands.

Shoppers can expect beautifully handcrafted jewellery, unique trinkets and wonderful staff who are open to have a natter.
It's the perfect shop for when you don't exactly know what to buy that someone special, just pop in here and you'll be hit with a wave of inspiration immediately.
We could've genuinely spent a good hour in there and come out with a much lighter wallet.
Lisa herself spoke about the opening: “As an independent retailer, we are thrilled to launch in a destination with such a reputation as Victoria Leeds.
"We believe retail should remain grounded in inspiration and discovery, and we look forward to bringing just that to the vibrant city of Leeds, in our first store in the north.”

Managing Director James Moody said: “We're incredibly excited to be opening our first northern showcase store in such a prestigious location.
"Victoria Leeds represents exactly the kind of vibrant retail destination where we can bring the full Lisa Angel experience to new customers. This is a significant milestone for us as we continue to grow our retail presence."
