Keto Big Mac Sauce: The Ultimate Low-Carb Copycat Recipe
Have you ever craved that iconic Big Mac flavor but worried it would kick you out of ketosis? What if you could recreate that legendary special sauce while keeping your carb count near zero? The secret to maintaining your keto lifestyle while indulging in fast-food flavors is easier than you might think.
Making your own keto big mac sauce at home isn’t just possible—it’s surprisingly simple and tastes remarkably like the real thing. With just a handful of low-carb ingredients, you can create a creamy, tangy condiment that transforms ordinary burgers into mouthwatering keto-friendly masterpieces.
Ingredients List
The beauty of this keto big mac sauce lies in its simple yet flavorful ingredient list. Each component works together to create that distinctive taste we all recognize, without the hidden sugars and carbs.
- 1 cup mayonnaise (full-fat, preferably avocado oil-based for healthier fats)
- 2 tablespoons sugar-free pickle relish (or finely chopped dill pickles)
- 2 tablespoons yellow mustard
- 1 tablespoon white vinegar
- 2 teaspoons paprika
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1/2 teaspoon salt (or to taste)
- 1-2 packets of monk fruit sweetener or erythritol (adjust to taste)
For substitutions, Greek yogurt can replace up to half the mayonnaise for a tangier profile with fewer calories. If you don’t have sugar-free pickle relish, finely diced dill pickles work perfectly. Apple cider vinegar can substitute for white vinegar, adding a subtle complexity to the flavor profile.
Timing
Preparation time: 5 minutes
Resting time (optional but recommended): 30 minutes
Total time: 35 minutes
This keto big mac sauce comes together in just 5 minutes of active preparation, which is 95% faster than making a traditional homemade sauce that might require cooking. The optional 30-minute rest in the refrigerator allows the flavors to meld beautifully, enhancing the final taste experience.
Step-by-Step Instructions
Step 1: Gather Your Ingredients
Measure all ingredients and have them ready at room temperature for the best blending results. Using room temperature mayonnaise will ensure a smoother consistency in your final sauce.
Step 2: Combine Base Ingredients
In a medium mixing bowl, combine the mayonnaise, mustard, and vinegar. Whisk thoroughly until the mixture becomes smooth and uniform in color. This creates the creamy base that will carry all the other flavors.
Step 3: Add Seasonings
Add the paprika, garlic powder, onion powder, and salt to the mixture. The paprika not only adds flavor but gives the sauce that signature pinkish-orange hue that makes it instantly recognizable.
Step 4: Incorporate Sweetener
Sprinkle in your chosen keto-friendly sweetener, starting with a smaller amount. Traditional Big Mac sauce has a subtle sweetness, so add just enough to balance the tanginess without making it too sweet.
Step 5: Fold in Pickle Relish
Gently fold in the sugar-free pickle relish or chopped pickles. If using chopped pickles, make sure they’re finely diced to distribute evenly throughout the sauce. This adds the characteristic texture and bursts of flavor in every bite.
Step 6: Taste and Adjust
Take a small taste and adjust seasonings as needed. Need more tang? Add a splash more vinegar. Want more sweetness? Add a bit more sweetener. The beauty of homemade sauce is customizing it to your preference.
Step 7: Rest and Refrigerate
Transfer the sauce to an airtight container and refrigerate for at least 30 minutes before serving. While you can use it immediately, allowing the flavors to meld creates a more authentic taste that closely mimics the original.

Compare this to the original Big Mac sauce, which contains approximately 5-7g of carbs per serving, primarily from added sugars. By making this keto version, you’re reducing carbohydrate content by over 80% while maintaining the classic flavor profile.
Healthier Alternatives for the Recipe
While this recipe is already keto-friendly, there are several ways to make it even healthier:
For a probiotic boost, substitute half the mayonnaise with sugar-free plain Greek yogurt. This adds beneficial bacteria while reducing calories and fat content by approximately 30% per serving.
Consider using avocado oil mayonnaise instead of traditional versions made with soybean or canola oil. Avocado oil contains more heart-healthy monounsaturated fats and fewer inflammatory omega-6 fatty acids.
For those sensitive to artificial sweeteners, try using a small amount of stevia extract or simply omit the sweetener altogether. The sauce will have a slightly tangier profile but remains delicious.
Boost the nutritional value by adding a teaspoon of turmeric alongside the paprika. This provides anti-inflammatory benefits and enhances the golden color without significantly altering the taste.
Serving Suggestions
This versatile sauce extends far beyond burger applications. Drizzle it over a deconstructed Big Mac salad with ground beef, lettuce, cheese, and diced pickles for a fork-friendly meal that satisfies fast-food cravings.
Use it as a zesty dipping sauce for keto-friendly chicken tenders, crispy bacon strips, or fresh vegetable crudités. The creamy texture makes it perfect for dipping firm vegetables like bell peppers, celery, and cucumber slices.
Transform ordinary scrambled eggs into a flavor-packed breakfast by adding a dollop of this sauce alongside avocado and cheese. The savory-tangy profile pairs surprisingly well with morning favorites.
For an impressive appetizer, stuff mushroom caps with a mixture of cream cheese and this sauce, then bake until golden. The umami flavors of the mushrooms complement the tangy sauce beautifully.
Common Mistakes to Avoid
- Using sweet pickle relish: Regular pickle relish contains significant added sugars. Always opt for dill or sugar-free varieties to keep carbs in check.
- Over-sweetening: The original sauce has just a hint of sweetness. Start with less sweetener than you think you need—you can always add more.
- Skipping the rest time: While technically optional, the 30-minute refrigeration allows flavors to develop fully. Rushed sauce often tastes one-dimensional compared to properly rested sauce.
- Using low-fat mayonnaise: Low-fat products typically contain added starches and sugars to compensate for flavor. Stick with full-fat mayo for both taste and keto compliance.
- Forgetting to taste-test: Ingredients can vary in potency, especially spices and sweeteners. Always taste and adjust before serving.
Storing Tips for the Recipe
Your homemade sauce will stay fresh in an airtight container in the refrigerator for up to two weeks. The vinegar and salt act as natural preservatives, but always check for any changes in smell or appearance before using.
For longer storage, portion the sauce into ice cube trays and freeze. Once frozen, transfer the cubes to a freezer bag for single-serving convenience. Thaw in the refrigerator overnight before using.
If the sauce separates after storage, simply give it a quick stir to recombine the ingredients. This is normal and doesn’t affect the quality or taste of your sauce.
Consider storing your sauce in squeeze bottles for easy application without mess. This restaurant-style approach makes burger assembly quicker and more precise.
Conclusion
Creating your own keto-friendly Big Mac sauce opens up a world of low-carb possibilities while satisfying those fast-food cravings that can sometimes derail a ketogenic lifestyle.
