Instructions
- Prepare burger seasoning, and use for the recipe. In a small bowl combine the kosher salt, ground black pepper, and garlic salt.
- Saute onions with butter on the grill. Sprinkle burger seasoning on the onions. Cook the onions until they are tender. Do not brown the onions.
- Butter each of the buns and cook the buns on the grill. Cook the buns on the grill until they are lightly brown.
- Form 8 balls of the burger meat. Heat the grill to about 350 degrees. Place the balls on the grill. Smash burger meat onto the grill. Season with burger seasoning.
- Cook for 2 to 3 minutes flip and continue to cook on the other side. Place 1 slice of Swiss cheese on each burger while they are on the grill.
- Build the burger by building up from the bottom by adding the two burgers with cheese on each bun. Then top with grilled onions, and spread some Boursin cheese on the top bun. Top the burger with the top bun.
Notes
- For the most authentic Smashburger experience, use a metal spatula with a sharp edge and press down firmly when smashing—don't be gentle! The key is to smash quickly after placing the meat on the hot grill. This creates the signature crispy edges that make Smashburger unique. For even better results, chill your meat balls for 15 minutes before cooking to help them hold together during the smashing process. Keep your onions tender but not browned for the proper flavor profile, and don't skip buttering and toasting the buns—it makes a significant difference in texture and taste.
