Homemade Keto Burger Sauce Recipe

This keto burger sauce is creamy, tangy, and packed with classic diner style flavor without added sugar. Made with simple low carb ingredients, it is perfect for burgers, lettuce wraps, and dipping.

If you love a classic burger special sauce but want to keep things low carb, this keto burger sauce delivers bold flavor with simple ingredients. It comes together in minutes and works just as well on burgers as it does as a dipping sauce for vegetables or low carb fries, and of course, pairs perfectly with my diner inspired keto copycat In N Out burger (aka protein style).

What Is Keto Burger Sauce?

Keto burger sauce is a low carb version of a classic burger or special sauce. It is typically made with a mayonnaise base and flavored with mustard, ketchup, pickles, and spices without added sugar.

Homemade keto burger sauce offers better control over ingredients and flavor while staying quick and versatile.

Why This Keto Burger Sauce Works

• Creamy base: Mayonnaise creates a rich, smooth texture that coats burgers evenly
• Balanced tang: Mustard and pickle juice add acidity to cut through the richness
• Savory depth: Minced onion and garlic powder bring classic diner style flavor
• Subtle sweetness: Sugar-free ketchup delivers familiar burger sauce sweetness without added carbs
• Perfect consistency: Thick enough to cling to burgers but easy to adjust for dipping or drizzling

Ingredients for Keto Burger Sauce

This recipe uses pantry-friendly, low-carb staples. Here’s what you need:

• Mayonnaise (avocado mayo works especially well)
• Sugar-free ketchup
• Yellow or Dijon mustard
• Dill pickles
• Onion
• Pickle juice
• Salt and black pepper
• Paprika
• Garlic Powder

How to Make Keto Burger Sauce

1. Chill briefly for best flavor, or serve immediately.

3. Stir in the minced pickles, onion, and pickle juice.
4. Season with salt, pepper, paprika, and garlic powder.
5. Adjust thickness with additional pickle juice as needed.

Tips for the Best Low-Carb Burger Sauce

• Finely mince the pickles and onion for a smooth, cohesive sauce.
• Let it rest for 10–15 minutes so the flavors can meld.
• Adjust the tang with more pickle juice or mustard if needed.
• Use avocado mayo for a cleaner flavor and better fat profile.

Ways to Use Keto Burger Sauce

This sauce is more versatile than just burgers:

• Sauce for grilled or smoked chicken, animal style sliders, or patty melts
• Burger bowls or lettuce-wrapped burgers
• Dipping sauce for low-carb fries or roasted veggies
• Spread for keto sandwiches or wraps

Storage and Make-Ahead Tips

• Store keto burger sauce in an airtight container in the refrigerator to maintain freshness and prevent the sauce from absorbing other flavors
• For the best texture and flavor, chill the sauce for at least ten to fifteen minutes before serving to allow the ingredients to fully meld
• The sauce will naturally thicken as it chills due to the mayonnaise base. Stir well before using
• Keto burger sauce keeps well in the refrigerator for up to seven days when properly stored
• This sauce is ideal for meal prep and can be made one to two days ahead for cookouts, grilling nights, or weekly lunches
• Freezing is not recommended, as mayonnaise-based sauces can separate and lose their creamy texture when thawed
