1. 1. Prepare the Ground Beef: First, heat a large skillet or cast iron pan over medium high heat. Add the ground beef to the hot pan. Break it apart with a spatula. Cook the beef until it completely browns, crumbling it as it cooks. Once fully cooked, drain any excess grease from the pan. Season the cooked beef with salt and black pepper. Stir well to combine. Remove the beef from the skillet and set it aside to cool slightly.

2. 2. Make the Keto Big Mac Dressing: In a medium bowl, combine all the dressing ingredients: mayonnaise, sugar free ketchup, sugar free dill pickle relish, yellow mustard, white vinegar, onion powder, garlic powder, smoked paprika, and the optional sweetener. Whisk everything vigorously until you achieve a smooth and creamy consistency. Taste the dressing and adjust seasonings if necessary. You might want a little more sweetness, tang, or spice.

3. 3. Assemble the Salad Base: Grab four large individual serving bowls or one large serving platter. Evenly distribute the chopped romaine lettuce among them or across the platter. This creates your crisp, refreshing base.

4. 4. Layer the Toppings: Next, equally divide the warm (or cooled) seasoned ground beef over the lettuce in each bowl. Then, sprinkle the shredded cheddar cheese over the beef. Follow with generous portions of chopped dill pickles and finely diced red onion.

5. 5. Finish and Serve: Drizzle a generous amount of the homemade Keto Big Mac dressing over each salad. Finally, garnish with a sprinkle of sesame seeds. Serve your Keto Big Mac Salad immediately and enjoy every delicious, low carb bite!
