As soon as tomorrow (30 December), you'll be able to get the much loved burger with or without bacon.
The Big Tasty is made with fresh 100 percent British and Irish beef, melty cheese made with Emmental, topped with tomato, lettuce, slivered onions and lashings of Big Tasty sauce, all on a sesame seed bun.
As the name says - it's big, it's tasty,
and only available for six weeks - so hurry up if you want to get your hands on
The Big Tasty will be available for £5.99, or you can get it with bacon for £6.39.
Also on the cards for tomorrow will be the new McNuggets. They're 100 percent chicken breast meat in a crispy Katsu Curry panko breadcrumb coating, served with our classic Sweet Curry dip (AKA the GOAT dip).
The new limited edition nugs are also launching on 30 December and represent the 'tastiest way to start 2021'.
McDonald's said: "The new limited edition Katsu Curry Chicken McNuggets are a match made in heaven and everything you didn't know you needed until this very moment.
"Hitting our restaurants on the 30 December, they are the tastiest way to wave goodbye to 2020 and start the new year as you mean to go on!
"If you want to try them then you'll have to be quick, as they're around for just six weeks."
You'll be able to pick up six Katsu Curry Chicken McNuggets for £3.59, nine Katsu Curry Chicken McNuggets for £4.09 or 20 Katsu Curry Chicken McNuggets for £5.99.
The final treat McDonald's will be offering us tomorrow is the signature limited edition Galaxy Salted Caramel McFlurry. It will be available to customers in both the mini and the full sizes.
McDonald's describes the dessert as: "The perfect combination of soft dairy ice cream with pieces of creamy Galaxy chocolate and a swirl of caramel sauce means it is a very popular choice, so make sure you can get one while it is available for 6 weeks."
The Galaxy Salted Caramel McFlurry will set you back £1.39 for the full sized one and 99p for the mini version.
