Description

Let me just say, this recipe is a game-changer! The first time I made these Keto Big Mac Smash Burgers, my family was blown away by how close they tasted to the real thing, but without the buns or the guilt. I love how the crispy lettuce acts as the perfect low-carb “wrap,” holding together all the classic flavors of a Big Mac—juicy beef, melted cheese, tangy pickles, and that iconic sauce. It’s a hit every time, and I’m confident it will be a go-to in your house too!

Instructions

Prepare the Big Mac Sauce:
In a small bowl, whisk together all the ingredients for the sauce—mayo, ketchup, mustard, pickle relish, vinegar, onion powder, garlic powder, salt, and pepper. Set aside in the fridge to let the flavors meld while you make the burgers.
Shape the Beef Patties:
Divide the ground beef into 6-8 small portions and gently roll them into balls. You don’t want them too compact. Season each ball of beef with salt, pepper, Worcestershire sauce, and mustard.
Cook the Smash Burgers:
Heat a large cast-iron skillet over medium-high heat. Once the skillet is hot, place a ball of beef in the skillet and press down with a spatula to “smash” it into a thin patty. Cook for 2-3 minutes, then flip. Add cheese on top of the patty and let it melt while the second side cooks for another 1-2 minutes. Repeat with the remaining patties.
Assemble the Burgers:
Place a lettuce leaf on a plate. Add a cheeseburger patty, top with pickles, onions, and a generous drizzle of the Big Mac sauce. Add another patty if you’re doubling up (optional). Fold the lettuce over like a wrap and serve.
