National Cheeseburger Day deals and freebies on Monday

Say cheese! National Cheeseburger Day arrives Monday, Sept. 18. Here's some tasty places to celebrate with deals and discounts.

DENVER — This article was first published by MileHighontheCheap.com.

National Cheeseburger Day arrives Monday, Sept.  18.

While there are many stories regarding the birth of the cheeseburger, many believe it all started right here in Denver. Back in 1935, a trademark for the name “cheeseburger” was awarded to Louis Ballast of the Humpty Dumpty Drive-In in Denver. Who knows the truth? All we know is that everyone loves a juicy cheeseburger!

Biting into the combo of a good bun, lettuce, tomato, pickle, cheese and juicy burger is so satisfying. Then, there are an endless number of condiments and kinds of cheeses to make it your very own, one-of-a-kind cheeseburger.

The following deals are only valid at participating locations and cannot be combined with any other discount or promotion. There is a limit of one offer per person, while supplies last.

There are no protein substitutions allowed — only beef burgers. Plus, none of the offers are available for third-party delivery.


Applebee’s is serving up their three Classic Burgers for $8.99 each on Monday.

The three choices are Classic Burger, Classic Cheeseburger and Classic Bacon Cheeseburger. Valid for dine-in, the Applebee’s website, or mobile app only. Not valid on third-party delivery sites.

Burger King

Get treated like royalty on National Cheeseburger Day at Burger King.

On Monday, Sept. 18, the fast-food restaurant is giving its Royal Perks loyalty members a free cheeseburger with a minimum purchase of $1. The offer is only available in the BK app.

And you can’t enjoy any burger without fries. Burger King is offering free any size fries every week for its loyalty members through the end of 2023. Unfortunately, you cannot combine the offers in the same transaction.
