Light Mayo Recipe: Creamy, Lighter Spread for Every Sandwich

Creating a lighter mayonnaise that doesn’t sacrifice creaminess is simpler than you might expect. This recipe delivers the same rich, velvety texture you love, but with a fraction of the fat. The key lies in precise emulsification and carefully balanced ingredient ratios that maintain that classic mayo mouthfeel.

What sets this version apart is its versatility. Use it as a base for sandwich spreads, salad dressings, or dips—it performs just like traditional mayo but with cleaner ingredients. The method ensures stable emulsification, so your mayo stays perfectly smooth without separation. Store it properly, and you’ll have a fresh, lighter condiment ready whenever you need it.

Ingredients for Light Mayo

Nine simple ingredients transform into a velvety, lighter mayo that rivals the classic version.

The Greek yogurt is the secret here—Fage 5% gives that perfect creamy texture without heaviness. Use light olive oil (not extra-virgin) to avoid overpowering flavor. For the egg yolk, room temperature is non-negotiable—cold yolks break emulsions. I always grab Dijon mustard from Trader Joe’s (their organic version is smooth and affordable). The vinegar and lemon juice balance each other—don’t skip either unless you want a flat-tasting mayo.

No Greek yogurt? Full-fat sour cream works in a pinch (just strain it first). Out of Dijon? Yellow mustard at half the amount gets you close. For a completely oil-free version, swap the oil for avocado puree—it’s surprisingly good. The sugar is optional but helps round out flavors. If you’re watching sodium, reduce the salt to an eighth teaspoon and add more to taste after blending.

This keeps 5-7 days in a sealed jar in the fridge. The emulsion might separate slightly—just whisk it back together. For longer storage, freeze in ice cube trays (thaw overnight in the fridge). Always use a clean spoon to avoid contamination. The flavor actually improves after 24 hours as everything melds together.

Step-by-Step Instructions for Light Mayonnaise

This method delivers a perfectly creamy, lighter spread that’s easier to make than you might think.

Step 1: Create the Emulsion Base

In a medium bowl, whisk together the large egg yolk, 2 tsp Dijon mustard, 1 tbsp white wine vinegar, and 1 tbsp lemon juice until completely smooth. I like to use a small wire whisk for this step—it creates more surface area for emulsification. The mixture should be pale yellow and slightly thickened after about 30 seconds of vigorous whisking.

Here’s the thing—temperature matters. Make sure your egg yolk is at room temperature, as cold ingredients can cause the emulsion to break. The mustard acts as your stabilizer, while the vinegar and lemon juice provide the necessary acidity for both flavor and preservation.

Step 2: Gradually Incorporate the Oil

Begin adding the 0.75 cup light olive oil in a very slow, thin stream while whisking constantly. I’m talking about 1-2 drops per second at the start. This gradual incorporation is crucial for building a stable emulsion. After you’ve added about ¼ cup of oil, the mixture should start to thicken noticeably.

At this point, you can increase the oil flow slightly, but maintain constant whisking. Watch for the mixture to become pale and creamy—this visual cue tells you the emulsion is forming properly. If it starts looking greasy, stop adding oil and whisk vigorously for 15-20 seconds to re-emulsify before continuing.

Step 3: Lighten with Yogurt and Water

Once all the oil is incorporated and you have a thick mayonnaise base, whisk in the 0.25 cup Greek yogurt. I use full-fat yogurt here because it blends smoothly without thinning the mixture too much. The yogurt adds that signature tang while significantly reducing the overall fat content compared to traditional mayo.

Now add the 2 tbsp water, one tablespoon at a time, whisking well after each addition. This step adjusts the consistency to that perfect spreadable texture. The water helps distribute the fat molecules more evenly, creating a lighter mouthfeel without sacrificing creaminess.

Step 4: Season and Adjust to Taste

Finish by whisking in the 0.25 tsp sea salt and 0.25 tsp granulated sugar. The salt enhances all the flavors, while the sugar (though optional) beautifully balances the acidity from the vinegar and lemon. Taste your creation—it should have a pleasant tang with just enough sweetness to round out the flavors.

Real talk: this is the moment that matters. If the consistency feels too thick, you can whisk in additional water 1 teaspoon at a time until it reaches your preferred texture. Remember that the mayo will thicken slightly as it chills in the refrigerator.

Step 5: Chill and Store Properly

Transfer your light mayo to a clean glass jar with a tight-fitting lid. Let it chill in the refrigerator for at least 1 hour before using—this resting time allows the flavors to meld completely. The texture will also firm up slightly during this chilling period.

Your homemade light mayo will keep for up to 1 week in the refrigerator. Always use a clean utensil when scooping to prevent contamination. The surface might develop a thin layer of oil over time—simply stir it back in before using. Each batch makes enough for about 4 servings, perfect for sandwiches, salads, or as a dip base.

Make-Ahead Tips for Leftovers

Prep Ahead Strategy

You can prepare the emulsion base (egg yolk, mustard, vinegar, lemon juice) up to 12 hours ahead. Store it covered in the fridge, then bring to room temperature before adding oil. This makes the process feel less rushed when you’re ready to finish. I often prep this base the night before sandwich day. 💡

Yogurt Substitution Prep

If using strained yogurt for extra thickness, do this 24 hours in advance. Line a fine-mesh strainer with cheesecloth, add ½ cup Greek yogurt, and let drain over a bowl in the fridge. The result is ultra-thick yogurt that blends seamlessly into your mayo.

Oil Temperature Control

For best results, measure your light olive oil into a separate container and let it sit at room temperature for 30 minutes before using. Cold oil can shock the emulsion and cause separation. I keep mine in a measuring cup on the counter while prepping other ingredients.

Flavor Infusion Prep

Want herb-infused mayo? Steep 1 tbsp fresh herbs (dill, basil, or tarragon) in the vinegar and lemon juice mixture for 1 hour before making the base. Strain out herbs before whisking with the egg yolk. This adds depth without changing the texture.

Batch Freezing

Make a double batch and freeze in ice cube trays for perfect single-serving portions. Once frozen, transfer cubes to a freezer bag. Thaw overnight in the fridge when needed. The texture remains surprisingly smooth after thawing if you whisk it briefly.

Equipment Prep

Chill your mixing bowl and whisk for 10 minutes before starting. This helps maintain stable temperatures during emulsification. I learned this trick from professional chefs—it makes a noticeable difference in the final texture. ❄️
