Gordon Ramsay roasted a chef who covered an expensive Wagyu steak with Nutella

• Gordon Ramsay roasted a chef who covered a Wagyu steak with Nutella on TikTok.
• Gustavo Tosta (@realguga on TikTok) told Insider it was one of his unconventional steak experiments.
• He's also cooked steak with peanut butter, mayonnaise, pineapple, and sparkling water.

Gordon Ramsay has reacted to many cooking videos on TikTok, but one of his most popular clips to date involves Nutella spread all over a pricey Wagyu steak.

"Nutella on Wagyu? Seriously!! You idiot Nutella sandwich," Ramsay wrote in the caption of the video, which has been viewed more than 31 million times.

But Gustavo Tosta, the Miami chef behind @realguga on TikTok, told Insider that his Nutella Wagyu steak is just one of the many unconventional steak experiments that he's become known for.

Tosta has cooked steak with everything from sparkling water and peanut butter to mayonnaise and pineapple. He gets much of his inspiration from his 2.58 million YouTube subscribers, who asked him to mix Nutella with Wagyu - one of the most expensive meats in the world.

"They said, 'Guga, we love Nutella, we love steaks, why don't we combine them together?' And my first thought was, 'That's crazy, why would I do that?'" he said with a laugh.

But Tosta has a "don't knock it until you try it" policy, so he decided to conduct a new experiment and film it for Ramsay. And his short TikTok definitely caught the "MasterChef" star's attention.

"What are you doing? Oh come on, Nutella on Wagyu?" Ramsay exclaims during the video. "You have to be kidding me. Stop it! Seriously? What an idiot!"

Tosta told Insider that he "couldn't stop laughing" when he saw Ramsay's reaction video.

"Let's be honest, Gordon Ramsay is a superstar, that's facts," he said. "It was the funniest thing I'd ever seen."

Tosta admits he also got a bit worried that the Michelin-starred chef didn't realize his Nutella steak was just an experiment. But his loyal followers soon flooded Ramsay's comments to set the record straight.

"I started looking at the comments and, to my surprise, all of my subscribers and viewers were telling him everything that I was thinking. 'Gordon you cannot roast Guga, what are you doing? He knows everything about meat!' I was like, wow, my viewers got my back! It was awesome," Tosta said.

Meat has always been Gustavo Tosta's passion

Tosta, who was born and raised in Brazil, has been cooking meat since he was just a child.

"I'm pretty sure the first thing I ever cooked was a hot dog," he told Insider. "I've always grilled stuff. My grandma used to cook for me all the time, and I always used to be in the kitchen and cooking outdoors."

But Tosta wouldn't make the Nutella steak again

Nowadays, Tosta loves to share his tips and tricks - along with his more unconventional food experiments - on his popular YouTube and TikTok channels, where he's always honest about the outcome.

"Honesty and transparency throughout my entire channel is very important," he said. "We'll tell you if it's disgusting."

And even Tosta wasn't a fan of the Nutella steak.

"I don't recommend you do that," he said. "It was a lot of fun, and that's the thing - when you're doing experiments, you learn a lot. Even as horrendous as it might sound, you really never know how meat will behave until you try it."

Some unconventional techniques that Tosta does love? Throwing in some MSG to improve your meat's flavor, or using pineapple to help tenderize an inexpensive steak.

"If you really want to use a cheap kind of meat, you need to tenderize it first," he said. "And one of the great ways to tenderize a steak is by using natural enzymes from fruit."

Tosta recommends throwing some pineapple in a blender and then covering your steak with it for 30 minutes. But don't leave it on for too long or your steak will disintegrate into mush.

While Tosta was glad to catch Ramsay's attention, he hopes the "MasterChef" star will get the chance to see what he can really cook one day.

"Then I'm pretty sure he'd approve of it," Tosta said. "But then, maybe not. It's Gordon, so who knows!"
