5 Minute Copycat Subway Mayonnaise

Just like every kid, mayonnaise used to be my only acceptable sandwich condiment. Out of all the brands, Subway is king. During a long weekend this summer, I decided to crack the code of the Subway mayonnaise recipe. After a bit of trial and error and lots of research, I have created the closest thing to Subway mayonnaise served outside of Subway restaurants.

What Makes the Subway Mayonnaise Recipe Special?

I honestly couldn’t tell you why (until recently) but the mayonnaise at Subway is different. Most mayonnaise is made out of an acid, salt, egg yolk and oil. This follows the same premise but switches some things up and adds lots of flavour enhancements to replicate the addicting flavour of Subway style mayonnaise.

Through my research, everyone said that S&W mayonnaise is the closest retail option to Subway. S&W lists their whole egg mayo ingredients as:

Soybean Oil, Whole Eggs (9%), Corn Syrup, Water, Canola Oil, Vinegar, Salt, Lemon Juice Concentrate, White Mustard (Distilled Vinegar, Water, Mustard Seed, Salt), Rosemary Extract, Paprika.

Research and Development

In order to try and replicate the Subway mayonnaise recipe at home, I started doing research about what people have tried that’s turned out close. The recipe I based this off was from AllRecipes. I followed the recipe exactly as it was and the taste of the oil was overpowering. It wasn’t a hit and certainly wasn’t Subway mayo.

The photo above was all the initial ingredients before blending and tasting for flavour.

I ended up playing with the ratios, as well as adding some additions to cut through the taste of the oil. I didn’t think that would be needed considering canola oil is notoriously plain tasting and neutral.

The Ingredients

Everything you need to make your own Subway mayonnaise recipe is as follows:

  • Eggs
  • Mustard Powder
  • Garlic Powder
  • Sugar
  • White Pepper
  • Salt
  • Vinegar
  • Lemon Juice
  • Salt
  • Neutral Oil of Choice

The only other thing you need is either an immersion blender (my recommendation), a real blender/food processor (more high maintenance, more time, more chance for a failure) or a bowl and a whisk (0% recommended – this will take forever).

The best part about the immersion blender is the speed and ease. This method is nearly fool-proof and takes all of about 35 seconds. I use this immersion blender and love it, and it is conveniently one of the cheapest options at only $54 Canadian. It’s a purchase that I didn’t think I’d use often but actually get tons of unexpected use from.

The Secret to 2 Minute Mayonnaise

Now. I’ve told you how important it is to have an immersion blender instead of a blender/food processor/whisk. Here is why. The picture above is after about 45 seconds of work with an immersion blender in a mason jar.

The key to make this work is to add all ingredients to the bottom of your mason jar, topping them all with oil. Once added, you place in the immersion blender at the very bottom. Keep it at the bottom and blend in pulses of 1-3 seconds at a time until an emulsion forms.

Once the bottom emulsifies, slowly (and I mean SLOWLY) raise the immersion blender. While you do that, don’t just move the blender upwards, move it in a circular type motion like the blender is walking up a spiral staircase. This mimics slowly adding in oil to a food processor, but is way faster with almost no effort.

Calories 122kcal


  • 2 eggs
  • 1/2 tsp mustard powder
  • 1/4 tsp garlic powder
  • 1/2 tsp sugar granulated
  • 1/4 tsp white pepper
  • 2 tsp vinegar distilled or wine vinegar
  • 1 tsp lemon juice freshly squeezed
  • 1/2 tsp salt
  • 2 cups neutral oil canola, vegetable


Immersion Blender Method (Easiest)

  • Add all ingredients to a quart sized mason jar, placing the oil on the top.
  • Place your immersion blender all the way touching the bottom of the jar and blend in 1/2 second – 1 second bursts until it forms an emulsion. Do not lift while you do this.
  • Once the mixture is emulsified, slowly pull up the immersion blender (KEY VERY SLOWLY) until it has reached the top and the whole mixture is combined.
  • For best results, move the immersion blender in circles as you go up so you don't have to reinsert it. There's a chance that the emulsion may break if you bring the blender up and down too much.
  • For best taste, allow to sit in the fridge over night. Store up to 2 weeks.
