keto big mac smash burgers

Keto Big Mac Smash Burgers are a low-carb twist on the classic Big Mac, featuring crispy smashed beef patties, melty cheese, and a special sauce, all wrapped in a low-carb tortilla.

Ingredients

Scale
  • 1 lb ground beef (80/20 works best)
  • 1 tsp kosher salt
  • 1/2 tsp black pepper
  • 1/2 tsp garlic powder (optional)
  • 46 low-carb tortillas (small/medium ‘carb balance’ style)
  • 46 slices American cheese (or cheddar)
  • 1/2 cup mayonnaise
  • 2 tbsp sugar-free ketchup
  • 1 tbsp yellow mustard
  • 2 tbsp dill pickle relish (or finely chopped pickles)
  • 1 tsp white vinegar (or pickle juice)
  • 1/2 tsp paprika
  • 1/4 tsp onion powder
  • 1/4 tsp garlic powder
  • Pinch of salt + pepper
  • 1 1/2 cups shredded iceberg lettuce
  • Dill pickle chips (the more, the better)
  • Optional: diced onion

Instructions

  1. Make the special sauce: Stir together mayo, sugar-free ketchup, mustard, relish, vinegar, paprika, onion powder, garlic powder, salt, and pepper. Set aside.
  2. Prep the beef: Divide ground beef into 4–6 balls (about 3–4 oz each). Season with salt, pepper, and garlic powder.
  3. Heat the pan: Warm a large cast iron or nonstick skillet over medium-high heat until hot.
  4. Smash onto the tortilla: Place a tortilla in the skillet. Set one beef ball in the center and smash it thin with a spatula (use parchment between spatula and beef). Press so the beef spreads close to the tortilla edges.
  5. Cook: Let cook 2–3 minutes until the beef is browned and crispy at the edges.
  6. Flip: Flip the whole thing so the tortilla hits the pan. Immediately add a slice of cheese on top of the beef and cook 1–2 minutes until the tortilla is lightly toasted and the cheese melts.
  7. Build: Remove from heat. Add shredded lettuce, pickle chips, and a generous drizzle of special sauce (plus onions if you like).
  8. Fold & serve: Fold like a taco and eat hot. Repeat with remaining tortillas and beef.

Notes

  • Smash thin for maximum crisp.
  • Keep lettuce and pickles cold and add after cooking.
  • Store components separately up to 3 days; reheat patties/tortillas in a skillet for best crisp.
