10 secrets to the perfect burger, according to chefs

‘My No. 1 secret for making the perfect burger is to ensure you have the perfect ingredients. The burger patty has to be made with a juicy blend of medium and lean meats, the bun either pretzel or brioche, and the cheese must be aged. I prefer my burger patties to be pressed for a smash burger and all dressed for a flavour bomb party.’—Chanthy Yen, founder of Touk and chef of Parliament Pub & Parlour in Montreal

‘The burger blend is the most important element. What’s a burger if you can't taste the beef? The second most important thing is everything else. You could have a wagyu blend but underseason it, overcook it, use sub-par toppings and cheap bread and end up with something incredibly unappetizing. There isn’t one secret. Everything takes a lot of care.’—Luciana Giangrandi and Alex Meyer, chefs and co-owners of Boia De in Miami

‘Extremely good grass-fed beef, from a breed that has plenty of marbled fat in it for flavour and great omega-3 oils, is the real secret. I try very hard to avoid all feedlot beef these days, as it is so dire for global warming and emissions and, not to mention, inhumane. Free-range, grass-fed beef is where it's at. You don’t need to eat it all the time, but you do need to make sure you know where its coming from – and you can taste it in the meat.’—Thomasina Miers, founder of Wahaca in London

‘Mix the ground beef with a delicious blend of garlic, onion, soy sauce and beef fat before forming the patty. It gives a very moist result, and the beef fat will enhance the beef flavour and also protect it from drying out.’—Agustin Ferrando Balbi, chef-founder of Andō in Hong Kong

‘Cook burgers using high heat – there’s no such thing as a slow-cooked burger… at least not a good one! Cooking with high heat sears the burger and locks in juices.’—Brian Jupiter, chef-owner of Ina Mae Tavern and Frontier in Chicago

‘If you are using the grill, the best way to get the oozing, melty cheese is to put some hot water in a heat-safe pot and close the grill. The steam will give you that melting perfection without drying the edges.’—Marwa Alkhalaf, chef-director of Nutshell in London

‘Without a doubt, butter. I know that sounds crazy, but butter is my secret weapon. It helps the good quality meat caramelize. Butter has an ability to really round out the beefy flavor and create a juicy and succulent burger.’—Nyesha Arrington, Los Angeles-based chef and former Top Chef contestant

‘The secret to making the best burger is not to press the patty when cooking it. That releases all its juices. Instead, pinch the center so that when it’s cooking, it doesn’t puff too much.’—Cesar Zapata, chef of Phuc Yea and Pho Mo at Time Out Market in Miami

‘My No. 1 secret for making the perfect burger is getting the grill nice and hot and keeping the toppings fresh and simple. Don't try to pile everything you’re craving on one burger, because it will just be too many competing flavors. Oh, and if you love crunch, add chips to your burger – it's a game changer!’—Kathryn Ferries, sous chef at Stofa Restaurant in Ottawa

‘As a vegan, my secret is to skip the meat and use kidney beans, oat flour and veggies in the mix. It took me years to come up with the RHK burger and it is absolutely amazing.’—Heather Costa, chef-owner of Revolution Health Kitchen at Time Out Market in Boston
