Copycat Smashburger French Onion Burger

You can make a copycat Smashburger French Onion burger at home. It is so easy to make this amazing burger at home.

Smashburger makes some of the best hamburgers that you can buy. They are flavorful, made with fresh meat, and made fresh to order. Smashburger is unique in how they prepare their burgers. Smashburger smashes the meat into the grill while cooking. By smashing the meat onto the grill the flavor and juice get locked into the meat. Smashburger does not use ordinary ground beef for their burgers they use minced chuck steak. Using higher quality of meats means that you get a better burger.

What makes the Smashburger French Onion Burger so special

Their French onion burger is a fun new burger that they serve on their limited menu. This burger features sauteed onions, Boursin cheese, swiss cheese, two patties all served up on a delightful onion bun. It’s not every day that you can find a burger that packs so much flavor in itself. This isn’t your ordinary burger, it is one that is extraordinary. The combination of Boursin and Swiss cheese you send up with a burger that is going to make you want to say “oui-oui”.

If you have never purchased Boursin cheese it is a brand of cheese that combines Gournay Cheese and mouthwatering herbs and spices to create an array of delicious flavors—delicately wrapped in our signature foil to preserve freshness. I have to be honest here, I love Boursin cheese, a slice of it makes an ordinary grill chicken breast turns chicken into something extraordinary. Whenever I have guests over I love to serve up some Boursin cheese, the plate of Boursin cheese always comes back empty. The creaminess of this cheese is the perfect substitution for mayonnaise or mustard on a burger.
