Simple Ingredients for Keto Big Mac Smash Burger

For the Burgers

• 1½ pounds ground beef (80/20)
• 8 slices cheddar cheese
• 2 cups shredded iceberg lettuce
• ½ cup diced white onion
• ½ cup sliced dill pickles
• 1 teaspoon salt
• 1 teaspoon black pepper
• 1 teaspoon garlic powder

For the Keto Burger Sauce

• ½ cup mayonnaise
• 2 tablespoons sugar-free ketchup
• 1 tablespoon yellow mustard
• 1 tablespoon sugar-free pickle relish
• ½ teaspoon garlic powder
• ½ teaspoon onion powder
• ½ teaspoon paprika
• 1 teaspoon pickle juice

Cooking Instructions

1. Prepare the Burger Sauce

Mix mayonnaise, sugar-free ketchup, mustard, relish, garlic powder, onion powder, paprika, and pickle juice in a bowl. Stir well until smooth. Place the sauce in the refrigerator while preparing the burgers.

2. Divide the Beef

Place the ground beef onto a tray. Divide it into eight equal portions. Roll each portion into a loose ball. Do not press the meat tightly because loose beef creates crispier edges.

3. Heat the Skillet

Place a cast iron skillet over high heat. Allow it to become very hot before cooking. A hot skillet creates the crispy golden crust that makes smash burgers taste amazing.

4. Smash the Patties

Place one beef ball onto the hot skillet. Use a sturdy metal spatula to press it flat. Season with salt, pepper, and garlic powder immediately after smashing.

5. Cook the First Side

Leave the burger untouched for about two minutes. The beef will develop crispy brown edges. Avoid moving the patty because this helps create the best crust.

6. Flip and Add Cheese

Carefully flip the burger with your spatula. Place one slice of cheddar cheese on top. Cook for another minute until the cheese melts completely over the juicy beef.

7. Cook Remaining Patties

Repeat the same process with all remaining beef portions. Keep the cooked patties warm on a plate covered loosely with foil while finishing the rest.

8. Assemble the Burger

Place shredded lettuce onto a serving plate. Add two cheesy smash patties. Top with diced onions, dill pickles, more lettuce, and plenty of creamy keto burger sauce.

9. Serve Fresh

Serve immediately while everything is hot and fresh. Enjoy every bite with extra sauce, crunchy pickles, and crisp lettuce for the best homemade burger experience.

Easy Storage and Reheating Guide

Store leftover burger patties in an airtight container inside the refrigerator for up to three days. Keep the lettuce, onions, pickles, and sauce in separate containers to stay fresh.

Reheat the burger patties in a hot skillet for about two minutes on each side. You can also warm them in an air fryer at 350°F for three to four minutes.

Avoid microwaving for too long because it softens the crispy edges. Fresh toppings should always be added after reheating.
