The oil is key here—canola or light olive oil (not extra-virgin, which overpowers). Diamond Crystal kosher salt gives the cleanest flavor. Eggs should be room temperature for smooth emulsification (cold eggs can break the mayo). Pasteurized eggs are ideal if you’re concerned about raw egg consumption, available at Whole Foods or most major grocers.

No Dijon? Yellow mustard at double the amount works in a pinch. Vinegar swap: apple cider vinegar at 1:1. The lemon juice can be bottled (fresh is best, but bottled is fine). For a slightly sweeter Duke’s-style mayo, increase sugar to 1.5 tsp. Oil can be avocado or grapeseed too—anything neutral.

Keeps in the fridge for about 1 week in an airtight jar (the acidity helps preserve it). The flavor deepens after 24 hours, so make it a day ahead if possible. Don’t freeze—it’ll separate and get weird.

Step-by-Step Instructions for Southern-Style Mayonnaise

Here’s the method that delivers that signature Duke’s tang and creamy texture at home.

Step 1: Combine Eggs and Acid Base

In a food processor or blender, combine the 2 whole Large Egg Yolks and 1 whole Whole Egg. Pulse for 10-15 seconds until the mixture is smooth and slightly frothy. This creates the foundation for your emulsion.

Add the 2 tbsp White Vinegar, 1 tbsp Lemon Juice, 1 tsp Dijon Mustard, 1 tsp Granulated Sugar, and 0.5 tsp Kosher Salt. Pulse again for 5-10 seconds until everything is fully incorporated. The acidity from the vinegar and lemon juice is what gives this mayo its characteristic tang.

Step 2: Begin the Emulsion with Oil

With the processor running on low speed, begin adding the 1.5 cups Neutral Oil in a very slow, thin stream. This is the most critical part of the process—adding the oil too quickly will break your emulsion.

After about 1 minute, you’ll notice the mixture starting to thicken and lighten in color. At this point, you can increase the oil stream slightly, but maintain a steady, controlled pour. The mixture should look like a thick, creamy sauce as the oil incorporates.

Step 3: Complete the Emulsion

Continue adding the remaining oil in that slow, steady stream. As you approach the end of the oil, you’ll see the mixture transform into a thick, glossy mayonnaise. This process should take about 3-4 minutes total from the first drop of oil.

Watch for the moment when the mayo pulls away from the sides of the bowl slightly and makes a soft “slap” sound as it hits the blades—this tells you the emulsion is properly formed. The texture should be smooth, thick, and pale, with no visible oil separation.

Step 4: Adjust and Rest

Once all the oil is incorporated, stop the processor and scrape down the sides with a rubber spatula. Give it one final 5-second pulse to ensure everything is fully combined. Taste and adjust seasoning if needed, though the initial measurements should give you that perfect Duke’s balance.

Transfer the mayonnaise to a jar or airtight container. Let it rest in the refrigerator for at least 30 minutes before using. This resting period allows the flavors to meld together and the texture to set completely. The finished product should be thick enough to hold its shape on a spoon but still spreadable.

Serving Suggestions for This copycat dukes mayonnaise

Classic Sandwich Spread

This mayo shines brightest on a simple BLT or tomato sandwich. I slather 2 tbsp on soft white bread with crispy bacon, ripe tomatoes, and fresh lettuce. The tang cuts through the richness perfectly.

Potato Salad Perfection

Use ½ cup to bind 2 lbs of boiled potatoes with celery, red onion, and hard-boiled eggs. The creaminess elevates the dish without overpowering. I add a pinch of paprika for color.

Let it chill for 1 hour before serving so flavors meld beautifully. 💛

Dip for Fries & Veggies

Mix ¼ cup mayo with 1 tsp smoked paprika and a dash of hot sauce for fries. For raw veggies, thin with 1 tbsp buttermilk for a lighter, tangier dip.

Deviled Eggs

Combine 3 tbsp mayo with 6 hard-boiled egg yolks, 1 tsp mustard, and salt. Pipe into egg whites and dust with paprika. This is my go-to for potlucks.

Grilled Cheese Upgrade

Spread 1 tbsp on the outside of bread before grilling for a golden, crispy crust. The mayo browns better than butter and adds that signature Southern flavor. 🔥
