The burger has been a part of the QSR chain's menu for 13 years.

CARPINTERIA, Calif. – The QSR chain Carl’s Jr. announced its popular Breakfast Burger will now be available all day, every day at participating restaurants.

The Breakfast Burger has been a staple of the Carl’s Jr. menu for more than a dozen years. It combines bacon, egg and hash brown with the burger including a charbroiled beef patty, American cheese and ketchup.

“When Carl’s Jr. created the Breakfast Burger over a decade ago, we became the first major hamburger QSR chain to put an egg on a burger, and it really was the perfect marriage of a great burger and classic breakfast items,” said Brad Haley, chief marketing officer of Carl’s Jr. and Hardee’s.  “While we’ve served burgers all day for a long time, serving breakfast all day is a big thing in the industry right now. So, the Carl’s Jr. way to meet that demand is to offer our classic Breakfast Burger all day long.”

The Breakfast Burger is available as a single patty burger for $4.39, a double burger patty for $5.69 and as a 100 percent Black Angus beef, 1/3-lb. Thickburger for $5.69. Prices may vary by location.
