Burgers

CLASSIC BUTTERY JACK®
Melted garlic herb butter on a juicy ¼ lb.* beef patty. Need we say more Nay. But we will anyway. Because this beautiful burger has all the fixins’—provolone cheese, creamy tomato sauce, green leaf lettuce, and fresh sliced tomatoes, all on a Gourmet Signature Bun. Need we say more Nay. For real, this time. *Weight before cooking
BACON & SWISS BUTTERY JACK®
Sometimes, a burger comes along that makes other burgers whimper in fear. This is that burger. Because this ¼ lb.* signature beef patty is topped with melted garlic herb butter, hickory smoked bacon, Swiss cheese, and creamy bacon mayo—and it’s all on a gourmet signature bun. Don’t apologize, it’d be weirder if you weren’t drooling right now. *Weight before cooking
DOUBLE JACK®
This isn’t just a burger. This is a Declaration of Delicious. Two juicy, 100% beef patties with American cheese, fresh sliced tomatoes, hand leafed lettuce, and real mayonnaise—all on a buttery bakery bun. Yeah, Great Britain wishes they could get their hands on this amazing piece of America.
ULTIMATE CHEESEBURGER™
Can a cheeseburger change the world Nah. Don’t be silly. But an Ultimate Cheeseburger With two beef patties, American and Swiss-style cheeses, real mayonnaise, mustard, and ketchup on a buttery bakery bun That can change the world, alright. And maybe Mars. And perhaps that planet with the cool rings around it.
BACON ULTIMATE CHEESEBURGER™
How do you make an Ultimate Cheeseburger—with two beef patties, American and Swiss-style cheese, real mayonnaise, mustard, ketchup, all on a buttery bakery bun—even more ultimate You add three slices of bacon. You read that correctly. Three. Whoever coined “three’s a crowd” has obviously never had this burger.
SOURDOUGH JACK®
You claim you’re not hungry, but that’s before you read about a 100% beef patty topped with bacon, tomato, Swiss-style cheese, real mayonnaise, and ketchup—all on toasted sourdough bread. One more time for emphasis. Toasted. Sourdough. Bread. See Now you’re hungry.
SPICY SRIRACHA BURGER
Bring the heat. Directly to your mouth. This inferno has it all—100% beef, hickory smoked bacon, sliced jalapeños, Pepper Jack cheese, cool shredded lettuce, and fresh sliced tomatoes with spicy, creamy sriracha sauce, all on Jack’s signature toasty sourdough bread. Give your tastebuds a pep talk now, before it’s too late.
JUMBO JACK® CHEESEBURGER
This is the cheeseburger other cheeseburgers have posters of in their bedrooms. A 100% beef patty topped with two slices of American cheese, lettuce, tomato, pickles, chopped onions, real mayonnaise, and ketchup on a Buttery Bakery Bun. Now, you want a poster too, huh
JUMBO JACK®
When you pick up the Jumbo Jack—made with a 100% beef patty topped with hand leafed lettuce, tomato, pickles, chopped onions, and real mayonnaise on a buttery bakery bun—your arms will tremble. And your mouth will open. It’s the delicious type of workout.
JR. JUMBO JACK®
Anywhere else this Jr. Jack would be senior. Because there is nothing junior about this honest-to-goodness beef patty topped with tomato, pickle, lettuce, and chopped onions—with the just-right amount of ketchup and real mayonnaise. But here It’s got some growing up to do.
JR. BACON CHEESEBURGER
You ever call something “junior,” ironically Well, if you haven’t, you’re about to. Because this Jr. Bacon Cheeseburger is a 100% beef patty topped with hickory smoked bacon, American cheese, real mayonnaise and ketchup. And now you have a “junior” appetite. See what we did there
