Most fast-food chains cook their burgers on flat griddles, but some still stick to the old-school flame-grilling method. Real grilling gives burgers that smoky, charred flavor that makes your mouth water. When flames kiss the meat, it creates a taste that flat cooking just can’t match.
1. Burger King

Flame-broiling has been Burger King’s signature cooking method since 1954. Their famous slogan “Have it your way” pairs perfectly with those distinctive grill marks that come from real fire.
Every Whopper gets cooked over an open flame conveyor system. This method creates that smoky taste and slightly charred edges that griddle cooking can’t replicate.
The flame-broiling process takes just the right amount of time to seal in juices while creating a crispy exterior. You can actually taste the difference in every bite.
2. Whataburger

Texas-based Whataburger takes pride in cooking every burger patty over real flames. Their commitment to flame-grilling has made them a beloved regional favorite across the South.
Each quarter-pound patty gets hand-formed and cooked to order on actual grills. The flame-kissed flavor comes through in every juicy bite, especially in their signature Whataburger with cheese.
Unlike many chains that pre-cook patties, Whataburger grills each burger fresh when you order. This dedication to quality flame-grilling keeps customers coming back for that authentic taste.
3. Culver’s

Culver’s ButterBurgers get their name from the buttered, toasted buns, but the real magic happens on the grill. Every patty is flame-grilled to perfection using fresh, never-frozen beef.
The Wisconsin-based chain uses a unique grilling technique that creates a crispy sear while keeping the inside tender. Their flame-grilling process brings out the natural beef flavors without overpowering seasonings.
What sets Culver’s apart is their commitment to grilling each burger when ordered. You might wait a few extra minutes, but that fresh-grilled taste is worth every second.
4. Hardee’s

Hardee’s switched to flame-grilling their premium burgers to compete with higher-end fast-food options. Their Thickburgers benefit tremendously from this real grilling approach.
The chain uses charbroiling equipment that creates authentic grill marks and smoky flavors. Each thick patty gets exposed to actual flames, creating that backyard barbecue taste in a fast-food setting.
Hardee’s flame-grilled burgers stand out because they focus on thick, substantial patties that can handle the intense heat. The result is a burger that tastes more like restaurant quality than typical fast food.
5. Carl’s Jr.

Carl’s Jr. uses flame-grilling for their premium burger lines, especially the famous Western Bacon Cheeseburger. The open-flame cooking method enhances the bold flavors they’re known for.
Their charbroiling process creates a perfect contrast between the crispy, flame-kissed exterior and juicy interior. The grill marks aren’t just for show – they represent real flavor development from actual fire.
The California-based chain discovered that flame-grilling works especially well with their larger, more indulgent burgers. The high heat quickly sears the outside while maintaining that perfect pink center.
6. Habit Burger Grill

Habit Burger Grill built their entire brand around the concept of flame-grilling every burger. Their tagline “Burger the Way it Should Be” reflects their commitment to real grilling techniques.
Each Charburger gets cooked over an open flame, creating that distinctive smoky flavor that sets them apart from griddle-cooked competitors. The flames caramelize the meat’s surface while sealing in natural juices.
The California chain’s flame-grilling process works perfectly with their fresh, never-frozen beef. You can watch the flames work their magic through the open kitchen design at most locations.
7. Freddy’s Frozen Custard

Freddy’s combines old-school flame-grilling with thin, crispy patties that cook quickly over real fire. Their unique approach creates burgers with maximum surface area for optimal flame contact.
The Kansas-based chain smashes their patties on the grill, allowing more meat to touch the flames directly. This technique creates incredible caramelization and those coveted crispy edges that burger lovers crave.
Freddy’s flame-grilling method works especially well because their thin patties cook fast and develop intense flavor. The result is a burger that’s crispy outside, juicy inside, and packed with smoky taste.
8. Steak ‘n Shake

Steak ‘n Shake has returned to flame-grilling their Steakburgers after years of using flat-top grills. The change back to real flames has improved their burger quality significantly.
Their flame-grilling process creates the perfect sear on their signature thin patties. The high heat from actual flames develops complex flavors that complement their classic burger preparations.
The chain’s commitment to flame-grilling shows in every bite of their hand-dipped milkshakes’ perfect companion. Real flames create the authentic taste that made Steak ‘n Shake famous decades ago.
9. Backyard Burgers

Backyard Burgers lives up to their name by flame-grilling every burger like you would in your own backyard. Their commitment to real grilling creates that authentic barbecue experience.
The chain uses actual charcoal and flame-grilling equipment to cook their fresh beef patties. This method produces genuine smoke flavor and those beautiful grill marks that make burgers look as good as they taste.
What makes Backyard Burgers special is their dedication to the slower flame-grilling process. Each burger takes time to develop proper char and smoky flavor, creating a more satisfying eating experience than quick-cooked alternatives.
