How to Make Keto Big Mac Smash Burgers
Ingredients
- 2 pounds ground beef
- 1 tablespoon salt
- 1 tablespoon pepper
- 1 tablespoon garlic powder
- 1 tablespoon onion powder
- 4 lettuce leaves
- 4 slices cheddar cheese
- 1/4 cup mayonnaise
- 2 tablespoons mustard
- 2 tablespoons sugar-free ketchup
- 1 tablespoon dill pickle relish
- Dill pickle slices (for topping)

Directions
Preheat your skillet over medium-high heat until hot and shimmering.
In a large bowl, mix together the ground beef, salt, pepper, garlic powder, and onion powder until combined.
Form the beef into balls (about the size of a golf ball) and place them in the hot skillet. Use a spatula to smash each ball down firmly, creating patties.
Cook the patties for about 3-4 minutes on each side, or until they are browned and reach your desired level of doneness.
In a small bowl, combine mayonnaise, mustard, ketchup, and dill pickle relish to create your special Big Mac sauce.
Top each burger with a slice of cheddar cheese, a crisp lettuce leaf, and dill pickle slices.
Drizzle the sauce generously over each burger before serving, allowing the flavors to melt together beautifully.
How to Serve Keto Big Mac Smash Burgers
These Keto Big Mac Smash Burgers are best served hot right off the skillet. For a simple yet appealing presentation, stack each burger on a plate and garnish with extra pickle slices or a sprinkle of fresh herbs. To complement these burgers, consider pairing them with a side of crispy zucchini fries or a refreshing garden salad. A cool beverage such as iced tea or sparkling water with lemon will enhance the dining experience.
How to Store Keto Big Mac Smash Burgers
If you have leftovers, store them in an airtight container in the refrigerator. They will remain fresh for up to 3-4 days. For longer storage, you can freeze the patties. Wrap each patty tightly in plastic wrap or aluminum foil before placing them in a freezer-safe bag. They can last up to 3 months in the freezer. When you’re ready to enjoy them, thaw in the refrigerator overnight and reheat in a skillet or microwave until heated through.
Tips to Make Keto Big Mac Smash Burgers
Don’t overcrowd the pan: Cook the patties in batches to get a nice sear.
Use room-temperature beef: It will help the burgers cook evenly and increase juiciness.
Experiment with cheeses: Try pepper jack or Swiss for a flavor twist.
Monitor cooking times: Adjust based on patty thickness to ensure doneness without drying.
Keep the sauce cold: This enhances the contrast of flavors when served.
Sauté the pickles: For a unique twist, try adding seared dill pickles as a topping.
Make sauces ahead: Prepare the Big Mac sauce in advance and store it in the fridge for quick assembly.
Flavor boost: Add a splash of Worcestershire sauce to the meat mixture for enhanced flavor.
Custom toppings: Add avocado slices or crispy bacon for extra richness.
Transform your leftovers: Use cold patties to create a salad or savory omelet.
