Recipe: Keto Big Mac Smash Burgers
Prep Time: 10 minutes | Cook Time: 10 minutes | Total Time: 20 minutes | Servings: 2 burgers
Ingredients
- 1 pound ground beef (80/20)
- 4 slices cheddar or American cheese
- 4 leaves lettuce (iceberg or romaine)
- 4 dill pickle slices
- 2 low-carb burger buns or large lettuce wraps
- 1/4 cup mayonnaise
- 1 tablespoon yellow mustard
- 1 teaspoon white vinegar
- 1/2 teaspoon paprika
- 1/2 teaspoon garlic powder
- 1/2 teaspoon onion powder
- 1/4 teaspoon salt
- 1/4 teaspoon black pepper
- Optional: 1 teaspoon sugar substitute (like erythritol)
Instructions
- In a small bowl, whisk together mayonnaise, mustard, vinegar, paprika, garlic powder, onion powder, salt, pepper, and optional sweetener. Set aside.
- Divide ground beef into 4 equal portions (about 4 ounces each). Roll each into a ball.
- Heat a large cast-iron skillet or griddle over high heat. Add a little oil if needed.
- Place beef balls in the hot skillet and immediately smash them flat with a spatula until about 1/4-inch thick. Season with salt and pepper.
- Cook for 2-3 minutes until edges are browned and crispy. Flip and cook for another 1-2 minutes.
- During the last minute of cooking, top each patty with a slice of cheese. Cover briefly to melt.
- Assemble burgers: On each bun or lettuce wrap, layer lettuce, two patties, pickles, and a generous drizzle of sauce. Serve immediately.
Tips
- For extra crispiness, use a metal spatula to press down firmly when smashing the patties.
- Make the sauce ahead of time and store in the fridge for up to a week.
- For a dairy-free version, use vegan cheese or omit cheese altogether.
