Make this keto Big Mac sauce with under 1g net carbs per serving. It captures the creamy, tangy flavor of the original without sugar or high fructose corn syrup. I've tested batches to perfect it for your burgers and salads.
Why the Original McDonald's Big Mac Sauce Fails Keto
The original Big Mac sauce from McDonald's uses soybean oil, sweet pickle relish with sugar, high fructose corn syrup, distilled vinegar, salt, and corn starch. These add hidden carbs.
Sources vary on nutrition. Carb Manager lists 1g net carbs per 2 tbsp. FatSecret shows 2g carbs per 0.7 oz. But 3g net carbs per tablespoon per some data—with 89 calories and 4g sugar.
High fructose corn syrup disrupts ketosis for many, even if net carbs seem low. Keto diets limit you to 20-50g net carbs daily. Sauces add up fast.
- Sweet relish: Pickled cucumbers in sugar syrup.
- HFCS and sugar: Glycemic spikes.
- Corn starch: Extra carbs.
I checked trackers. The sugars make it unreliable for strict ketosis.
Key Ingredient Swaps for Keto Success
Replace sweet pickle relish with dill pickle relish or minced dill pickles. Vlasic or Heinz brands work—0g net carbs if no added sugars. Check labels.
Ditch regular ketchup for sugar-free ketchup. Or mix tomato paste, white vinegar, and monk fruit.
Skip added sugars. Use allulose or monk fruit for subtle sweetness. Allulose mimics sugar's mouthfeel without bitterness. Omit it—the mustard and vinegar balance flavors.
Upgrade mayonnaise to avocado oil mayonnaise or homemade. Avoid soybean oil for less inflammation. Keeps the creamy emulsion.
Spices nail the taste:
- Onion powder
- Garlic powder
- Smoked paprika for earthiness and color
- Garlic salt optional for savoriness (watch sodium)
Ingredients for Keto Big Mac Sauce
This batch yields about 3/4 cup (12 tablespoons). Based on tested ratios like Home. Made. Interest. recipe.
| Ingredient | Amount |
|---|---|
| Avocado oil mayonnaise | 1/2 cup |
| Dill pickle relish (sugar-free) | 4 tablespoons |
| Yellow mustard | 2 tablespoons |
| Sugar-free ketchup | 1 tablespoon |

How to Make Keto Big Mac Sauce: No-Cook Method
Prep takes 5-10 minutes. No cooking needed.
Add avocado oil mayonnaise, dill relish, sugar-free ketchup, yellow mustard, and vinegar to a bowl.
Sprinkle in paprika, onion powder, and garlic powder.
Whisk until smooth emulsion forms.
Refrigerate for at least 30 minutes. Overnight best—spices hydrate, flavors meld.
From my testing, chilling transforms it. Use pickle juice to thin if too thick.
Pro Tip: Finely mince fresh dill pickles or grate them for extra crunch. Add a pinch of dill weed for authentic pickle pop without carbs.

Storage Rules for Freshness
Store in an airtight glass jar in the fridge.
- Lasts 7-10 days typically.
- High acidity may extend to 3 weeks.
- Use clean spoon each time—no cross-contamination.
- Stir before use if separated.
Do not freeze. Mayonnaise emulsion breaks, turns watery.
Signs of spoilage: discoloration, off odors, mold, texture changes. Discard then.
Dietary Adaptations and Allergens
Naturally gluten-free. Adapt for others:
| Concern | Solution |
|---|---|
| Egg allergy | Use egg-free vegan mayo |
| Soy avoidance | Avocado oil or olive oil mayo |
| Vegan | Plant-based mayo, honey-free mustard |
| Dairy | Skip any yogurt variations—base is dairy-free |
Check commercial brands for cross-contamination.
Common Problems and Fixes
I hit these in testing. Easy solves:
- Too thin? Chill longer or add 1 tbsp more mayo. Vinegar overload thins it.
- Too thick? Thin with 1 tsp pickle juice—boosts flavor.
- Not tangy? More mustard or vinegar.
- Lacks depth? Overnight chill.
- Too spicy? Cut paprika/garlic.
- Separates? Whisk before serving.
