Keto Salad Dressing Recipe Mayo: Rich Creamy Flavor Without the Sugar

This keto-friendly dressing delivers the creamy richness you love without the sugar spike. I developed this recipe to satisfy cravings for classic creamy dressings while staying strict to keto guidelines.

The base is simple mayonnaise, which provides that signature rich texture keto diets often miss. A few quality ingredients transform it into a versatile dressing that works on everything from crisp greens to hearty chef salads.

You’ll get a smooth, tangy dressing that clings perfectly to every leaf and veggie. It stores beautifully in the fridge for up to two weeks, making it ideal for meal prep and quick lunches.

Make a double batch—this becomes a staple in any keto kitchen. Here’s how to whip it up in minutes.

Ingredients for Keto Salad Dressing Recipe Mayo

A handful of keto pantry staples blend into silky, tangy perfection for your salads.

The mayonnaise base sets the tone—Duke’s or Hellmann’s Real are top picks for that perfect creamy texture. Sour cream adds richness, but full-fat Greek yogurt works if that’s what you’ve got. For the vinegar, I lean toward apple cider for its mellow tang (the Bragg brand is always in my pantry). Dijon mustard brings depth—Maille or Grey Poupon are solid choices.

No sour cream? Full-fat plain yogurt at the same amount does the trick. Apple cider vinegar can be swapped for white wine or rice vinegar—just keep the quantity the same. If you’re avoiding Worcestershire sauce, coconut aminos at half the amount gives a similar umami kick. Fresh dill works too (use triple the dried amount). The garlic and onion powders are subtle but essential—don’t skip them.

This keeps 2 weeks in the fridge—stir before using, as it’ll thicken slightly. For longer storage, freeze in ice cube trays (it’ll separate a bit but re-emulsifies when whisked). Always use a clean spoon to prevent contamination.

Step-by-Step Instructions for Keto Salad Dressing

This simple method delivers a luxuriously creamy dressing with perfect balance every time.

Step 1: Combine the Creamy Base

In a medium mixing bowl, whisk together the 1 cup Mayonnaise and 0.25 cup Sour Cream until completely smooth. I always use full-fat versions here—they create that rich, velvety texture that makes this dressing so satisfying.

This base provides the body for your creation. The mayonnaise gives it structure while the sour cream adds a subtle tang and extra creaminess. You’ll notice the mixture becomes slightly paler as air incorporates—this is normal and helps create a lighter mouthfeel.

Step 2: Add the Acidic Elements

Next, add the 2 tbsp Apple Cider Vinegar and 1 tbsp Lemon Juice. Whisk vigorously for 30 seconds until fully emulsified. The acidity brightens the richness of the base and balances the flavors beautifully.

Here’s the thing—this is where the magic starts to happen. The vinegar and lemon juice cut through the fat, creating that perfect harmony between creamy and tangy. I like to use freshly squeezed lemon juice for the best flavor, but bottled works in a pinch.

Step 3: Incorporate the Flavor Boosters

Now, add the 1 tbsp Dijon Mustard, 1 tsp Worcestershire Sauce, 0.5 tsp Garlic Powder, and 0.5 tsp Onion Powder. Whisk until all ingredients are thoroughly combined. The Dijon adds a subtle depth, while the Worcestershire brings umami complexity.

The garlic and onion powders provide a mellow, savory backbone without overpowering the dressing. Make sure to use garlic powder, not garlic salt, to avoid making the dressing too salty.

Step 4: Finish with Herbs and Seasoning

Finally, stir in the 0.5 tsp Dried Dill, 0.25 tsp Salt, and 0.25 tsp Black Pepper. I prefer using dried dill here for convenience, but you can substitute 1 tsp fresh dill if you have it on hand.

Taste and adjust the seasoning if needed. The salt enhances all the flavors, while the pepper adds a slight kick. If you’re using fresh dill, finely chop it to distribute evenly throughout the dressing.

Step 5: Rest and Serve

Let the dressing sit for at least 10 minutes before using. This resting time allows all the flavors to meld together, creating a cohesive and balanced taste. The mixture might thicken slightly as it sits—this is perfect for clinging to your greens.

Give it a final whisk before serving to re-emulsify any separated components. This dressing keeps beautifully in the refrigerator for up to 1 week in an airtight container. Just give it a good stir before each use.

Storing and Reheating keto salad dressing recipe mayo

Fridge Storage

Transfer your dressing to a clean glass jar with a tight lid—I use mason jars for easy mixing. It stays fresh in the fridge for up to 2 weeks. Always use a clean, dry spoon to prevent contamination. 💡

Thickening Over Time

After a few days, it may thicken slightly. Just whisk in 1-2 tsp water or lemon juice to restore the perfect consistency. The flavors actually deepen as it sits, making it taste even better after 24 hours.

Freezing Option

For longer storage, portion into ice cube trays and freeze for up to 3 months. Thaw overnight in the fridge, then whisk vigorously to re-emulsify. It may separate slightly, but this is normal for mayo-based dressings.

No Reheating Needed

This dressing is meant to be served cold. Simply give it a good stir before each use to redistribute any settled herbs or spices. The cold temperature helps maintain its creamy texture and fresh flavor.

Signs of Spoilage

If you notice any off odors, mold, or separation that won’t re-emulsify, it’s time to make a fresh batch. With proper storage, this rarely happens within the 2-week window. ❄️

Meal Prep Tip

Make a double batch on Sunday and store in the fridge. It’s ready to grab for quick lunches all week, and the flavors only improve with a day or two of resting time.
