Duke’s Mayo Copycat Recipe: Southern-Style Creamy Tang With a Secret Twist

This homemade version captures Duke’s signature tang and creamy texture without compromise. I’ve tested countless variations to nail that distinct Southern flavor profile that sets it apart from other mayonnaises.

The secret lies in the precise ratio of vinegar to egg yolks, plus one unexpected ingredient that replicates the original’s subtle depth. It comes together in 10 minutes with basic kitchen tools, no special equipment needed.

What you get is a rich, velvety condiment with the perfect balance of tang and creaminess. It spreads smoothly, holds up to sandwiches, and tastes exactly like the beloved Southern staple.

Use it everywhere you’d reach for the jarred version. Here’s how to make this copycat recipe at home.

Ingredients for Duke’s Mayo Copycat

Seven simple ingredients recreate that iconic Southern tang and velvety texture at home.

The oil is everything here. Avocado oil gives the cleanest flavor, but any neutral oil works—just avoid strong olive oils. For the vinegar, Distilled white is non-negotiable for authenticity. I grab mine from Walmart or Target—no need for fancy brands. Room temperature yolks emulsify faster, so pull them out 30 minutes before starting (or microwave 10 seconds if you’re impatient).

No Dijon? Yellow mustard at half the amount works in a pinch, but the flavor won’t be as complex. Out of white vinegar? Apple cider vinegar adds color but changes the taste slightly. For a lighter version, cut the oil by a quarter—it’ll be thinner but still delicious. The sugar is subtle but essential; don’t skip it (trust me, I tried).

This keeps in the fridge for about 2 weeks in a sealed jar. The flavor deepens after a day, so make it ahead if you can. If it separates, just whisk it back together. Freezing isn’t recommended—it breaks the emulsion.

Step-by-Step Instructions for Duke’s-Style Mayonnaise

Here’s the method I’ve perfected to replicate that signature Southern tang and creamy texture.

Step 1: Whisk Egg Yolks and Acidic Components

In a medium bowl, whisk together the 2 whole Large Egg Yolks, 2 tbsp Distilled White Vinegar, and 1 tsp Dijon Mustard until fully combined. I like to use a small balloon whisk for this—it creates just the right amount of air without overworking the mixture.

The dijon mustard acts as an emulsifier, so make sure it’s fully incorporated. The mixture should look pale yellow and slightly thickened. At this stage, you’re building the flavor base that gives this mayo its characteristic zing.

Step 2: Incorporate Sweet and Salty Balance

Add the 0.5 tsp Granulated Sugar and 0.5 tsp Kosher Salt to the yolk mixture. Whisk for another 20-30 seconds until the sugar and salt are completely dissolved. You won’t see visible grains, but you’ll notice the mixture becomes slightly more fluid.

This is the secret to balancing the vinegar’s sharpness. The granulated sugar mellows the acidity while the kosher salt enhances all the flavors. I always use Diamond Crystal for this—it dissolves evenly and has the perfect texture for mayo.

Step 3: Begin the Emulsion with Neutral Oil

Here’s where the magic happens. Start adding the 1.25 cups Neutral Oil 1 tablespoon at a time, whisking constantly after each addition. This slow incorporation is crucial for creating a stable emulsion that won’t separate.

After the first ¼ cup is incorporated and the mixture starts to thicken, you can begin adding the oil in a very thin, steady stream while whisking vigorously. The mixture will transform from a thin liquid to a creamy, pale emulsion before your eyes.

Watch for the color to lighten significantly—that’s your visual cue that the emulsion is forming properly. If it looks too thick, don’t worry; the remaining oil will adjust the consistency.

Step 4: Finish with Brightness and Adjust

Once all the neutral oil is incorporated, whisk in the 1 tsp Lemon Juice. The fresh lemon adds a brightness that complements the distilled white vinegar beautifully. You’ll notice the mayo becomes even creamier and develops a subtle sheen.

Taste and adjust the seasoning if needed, though I find the initial measurements hit that perfect Duke’s balance every time. The texture should coat the back of a spoon thickly and hold its shape when spooned. If it’s too thick, you can whisk in a teaspoon of warm water to loosen it slightly.

Transfer to a jar with a tight-fitting lid and refrigerate for at least 1 hour before using. This resting time allows the flavors to meld and the emulsion to fully set.
