Ingredients

For the Tacos

  • 1 lb lean ground beef (93% lean / 7% fat) (454g)
  • Nonstick cooking spray
  • 6 low carb tortillas (6″ size, 43g each), such as Mission Carb Balance
  • Salt and pepper to taste
  • 1 cup iceberg lettuce, shredded (72g)
  • ¼ cup sweet onion, minced (24g)
  • 1 dill pickle, sliced (35g)
  • Sesame seeds or everything bagel seasoning, for garnish

For the Big Mac Sauce

  • ½ cup blended cottage cheese (120g)
  • 3 tablespoons light mayonnaise (27g)
  • 2 tablespoons pickle relish or grated/finely chopped dill pickle (30g)
  • 1 teaspoon pickle juice (omit if using pickle relish)
  • 1 tablespoon + 1 teaspoon sugar-free ketchup
  • ¾ teaspoon yellow mustard
  • ½ teaspoon monk fruit sweetener or preferred sweetener, to taste
  • ¼ teaspoon garlic powder
  • ¼ teaspoon onion powder
  • ¼ teaspoon salt
  • ¼ teaspoon paprika

Instructions

  1. Prepare the Big Mac Sauce: In a blender or food processor, combine the blended cottage cheese, light mayo, pickle relish (or chopped dill pickle), pickle juice (if using), sugar-free ketchup, yellow mustard, monk fruit sweetener, garlic powder, onion powder, salt, and paprika. Blend until smooth and creamy. Adjust seasoning to taste and set aside.
  2. Cook the Ground Beef: Heat a nonstick skillet over medium-high heat and lightly coat with nonstick cooking spray. Add the ground beef, season with salt and pepper, and cook until browned and cooked through, breaking it up into small pieces with a spatula for a crumbled texture, about 6–8 minutes. Drain any excess fat if needed.
  3. Warm the Tortillas: Lightly warm the low-carb tortillas in a separate skillet or microwave for a few seconds until pliable but not crispy.
  4. Assemble the Tacos: Place warm tortillas on plates. Spread a generous spoonful of the prepared Big Mac sauce onto each tortilla. Add a layer of cooked ground beef, then top with shredded iceberg lettuce, minced sweet onion, and sliced dill pickles.
  5. Garnish and Serve: Sprinkle sesame seeds or everything bagel seasoning over the top to mimic the classic Big Mac bun texture and flavor. Serve immediately while warm and enjoy your low-carb Big Mac smash tacos.

Notes

  • You can use regular mayonnaise if light mayo is unavailable, but this will increase calories.
  • If you prefer, substitute the low carb tortillas with lettuce wraps for an even lower-carb, gluten-free version.
  • The monk fruit sweetener helps balance the tanginess in the sauce, but adjust sweetness to your preference or omit if desired.
  • For a spicier kick, add a pinch of cayenne or hot sauce to the sauce mix.
  • Make sure to cook the beef thoroughly to 160°F for safety, especially when using lean ground beef.
