What is a Keto Big Mac Smash Burger?
The Keto Big Mac Smash Burger is basically a Big Mac re-made for a keto diet . All the best parts are there — smashed beef patties , special sauce , cheese , pickles , onion — but instead of buns you use lettuce leaves . That switch keeps the carbs really low .
Compared to a regular Big Mac , you swap out the buns for lettuce and use fattier ground beef so it stays juicy . The sauce is made with sugar-free mayo , mustard , and even sugar-free ketchup so you still get that familiar taste .
The “smash” part means you press the beef balls flat on a hot pan or grill so they form a crispy edge . That crust locks in the juices and makes every bite delіcious and tender .
