Instructions / Method 👩‍🍳

Step 1: Prepare the Big Mac Sauce 🥄

In a medium bowl, combine all sauce ingredients: mayonnaise, chopped pickles or relish, yellow mustard, sugar-free ketchup, vinegar, paprika, garlic powder, onion powder, salt, and pepper.
If using, add sweetener, grated onion, and/or a few drops of Tabasco for heat.
Mix thoroughly until well combined and smooth.
For best flavor development, cover and refrigerate for at least 30 minutes while you prepare the other components.

Flavor tip: The sauce tastes even better when made a few hours ahead or the day before, allowing the flavors to fully meld together.

Step 2: Prepare the Burger Patties 🥩

In a large bowl, combine ground beef with garlic powder, onion powder, salt, and pepper. Mix gently with your hands until just combined, being careful not to overwork the meat.
Divide the seasoned meat into 4-8 equal portions (depending on how many burgers you’re making) and form into loose balls.
Have your keto tortillas or buns ready and set aside.

Handling tip: Cold meat is easier to work with, so keep your ground beef refrigerated until just before forming the patties.

Step 3: Cook the Smash Burgers 🔥

Heat a large cast-iron skillet or griddle over medium-high heat until very hot.
Place a keto tortilla on your work surface and put a ball of seasoned ground beef in the center.
Cover with a piece of parchment paper and use a flat spatula, burger press, or the bottom of a heavy glass to press the meat into a thin patty that spreads to the edges of the tortilla.

Once the cooking surface is hot, carefully place the tortilla meat-side down onto the skillet.
Use your spatula to firmly smash the patty even flatter against the hot surface. This creates the signature crispy edges of a smash burger.

Continue by

Cook for 3-4 minutes until the edges are crispy and the burger is mostly cooked through.
Carefully flip the burger so the tortilla side is now down.
Immediately place a slice of American cheese on top of the meat.
Cook for another 2-3 minutes until the cheese is melted and the tortilla is crisp.
Transfer to a plate and repeat with remaining patties.

Cooking tip: Don’t overcrowd the pan – cook in batches of 2-3 burgers at a time for best results.

Step 4: Assemble Your Keto Big Mac Smash Burgers 🍽️

Spread a generous amount of the prepared Big Mac sauce on top of each burger.
Add a handful of shredded iceberg lettuce on top of the sauce.
Place 3-4 pickle slices on each burger.
If using, sprinkle with diced onions.
Serve immediately while hot and crispy.

Assembly tip: For extra authenticity, you can make double-decker burgers by stacking two smaller patties with sauce and lettuce between them.

Cooking Tools & Equipment 🛠️

Large cast-iron skillet or flat griddle
Spatula (preferably metal with a straight edge for smashing)
Medium mixing bowl (for sauce)
Large mixing bowl (for meat)
Measuring spoons and cups
Parchment paper
Burger press or heavy, flat-bottomed object for smashing
Sharp knife for chopping vegetables
Cutting board

Equipment note: While a cast-iron skillet is ideal for achieving the best crispy texture, any heavy-bottomed pan will work in a pinch.

Flavor Profile 🌶️

Taste Description

These Keto Big Mac Smash Burgers deliver a perfect balance of savory, tangy, and slightly sweet flavors that replicate the classic Big Mac experience. The crispy-edged beef patties provide rich umami notes while the special sauce brings that signature tangy, creamy element that makes Big Macs so addictive.

Key Flavors & Spices

The magic happens in the sauce with its combination of creamy mayonnaise, tangy pickles, pungent mustard, and warm spices like paprika and garlic powder. The beef patties are enhanced with simple seasonings that complement rather than compete with the sauce.

How to Balance the Flavors

Too tangy? Add a bit more mayonnaise or a touch more sweetener to the sauce.
Not tangy enough? Increase the pickle relish, vinegar, or mustard.
Bland patties? Don’t skimp on salt and pepper in the meat mixture.
Want more kick? Add more Tabasco or chili powder to the sauce.

Cut smaller burgers in half and secure with toothpicks for party appetizers.

Garnishing Tips

Add a few extra pickle slices on the side.
Serve with extra Big Mac sauce in a small dipping bowl.
For color and freshness, add a small sprig of parsley or a slice of fresh tomato on the side.

Storage & Shelf Life ❄️

Refrigeration: Cooked patties can be stored in an airtight container in the refrigerator for up to 3 days.
Freezing: Uncooked seasoned patties can be frozen for up to 3 months. Separate them with parchment paper for easy thawing.

Reheating: For best results, reheat patties in a skillet over medium heat for 2-3 minutes per side or in an air fryer at 350°F (175°C) for 2-3 minutes. Microwave reheating works but may result in less crispy texture.

Storage tip: Store components separately and assemble just before eating to prevent soggy tortillas.

Cooking Tips & Tricks 🔥

Techniques for Better Results

Hot pan is crucial: Make sure your skillet or griddle is properly heated before adding the patties for optimal searing and crisping.
Don’t skimp on pressing: The firmer you press the patties, the better the crispy edges will develop.
Season generously: Don’t be shy with salt and pepper—properly seasoned beef makes all the difference.
Tortilla selection matters: Choose the lowest carb tortillas you can find—some brands have as little as 1g net carb per tortilla.
Cheese placement: Place cheese on the patty immediately after flipping to ensure proper melting.

Time-Saving Hacks

Prep sauce in advance: Make a bigger batch of Big Mac sauce and store it for multiple meals.
Pre-form patties: Season and shape your meat in the morning or the night before.
Mise en place: Chop all vegetables and prepare toppings before starting to cook.
Assembly line approach: For multiple burgers, set up an assembly station to quickly build each burger.

When Things Go Wrong 🤔

Problem: Burgers falling apart
- Solution: Make sure your meat is cold when forming patties, and don’t flip too early during cooking.
Problem: Tortillas breaking
- Solution: Warm tortillas slightly before using to make them more pliable, or try a different brand with better flexibility.
Problem: Sauce too runny
- Solution: Add more mayonnaise to thicken, or chill longer before using.
Problem: Patties too thick
- Solution: Use a heavier object for pressing and don’t be afraid to really smash them thin.
Problem: Not crispy enough edges
- Solution: Ensure your pan is hot enough before adding patties and press firmly when smashing.

FAQs ❓

Can I substitute the American cheese with another type of cheese?

Yes! While American cheese melts beautifully, you can substitute with cheddar, Swiss, pepper jack, or any melty cheese you prefer. For strict keto, check that your cheese doesn’t contain added starches or fillers.

How do I keep the carb count as low as possible?

Choose the lowest carb tortillas available (some brands have as little as 1g net carb), use sugar-free condiments, and be mindful of quantities of onions and tomatoes if added. Skip any sweetener in the sauce to reduce carbs further.

Can I make these ahead of time for meal prep?

You can prepare components separately (cook patties, make sauce, chop vegetables) but assemble just before eating for best texture. Reheat patties separately and assemble fresh.

What’s the best type of ground beef to use?

80/20 or 85/15 ground beef provides the best flavor and juiciness for smash burgers. Leaner beef (90/10) will work but may result in drier patties.

Can I make these without the tortillas?

Absolutely! Lettuce wraps work great as a zero-carb alternative. Large romaine or iceberg lettuce leaves make excellent wrappers.

How spicy is the Big Mac sauce?

Traditional Big Mac sauce is mildly tangy but not spicy. Add Tabasco, cayenne, or chili powder if you prefer more heat.

Is this recipe truly keto-friendly?

Yes! With approximately 2-6g net carbs per burger (depending on your tortilla choice), these fit perfectly into a ketogenic diet that typically allows 20-50g net carbs daily.

Can I double the recipe for a larger crowd?

Definitely! The recipe scales easily—just double all ingredients. Cook in batches to ensure proper searing and crispy edges.
