Greek yogurt is an excellent mayo substitute for tuna salad.

High in protein, Greek yogurt is a healthy alternative to those worried about their calorie or fat intake.

It is also relatively flavorless and will not alter the overall tuna salad taste as mayonnaise does.

It has a thick, creamy texture that mimics that of mayo and provides a good amount of moisture to the dish.

For a creamier texture, you can make your own Greek yogurt by draining regular yogurt through cheese cloth.

This process removes excess whey and leaves you with thick Greek yogurt perfect for blending into tuna salad.

2 – Avocado

Avocado is perfect for those who prefer to stay away from mayo, but still want a creamy, flavorful dressing.

This fruit has a mild flavor and unique texture when blended, making it a great option for tuna salad.

You can mash the avocado with a fork or blend it into a creamy dressing or dip-like consistency.

Be careful when adding salt as this fruit is high in sodium too.

3 – Cottage Cheese

Cottage cheese is an excellent way to lighten up tuna salad without skipping out on the creamy texture.

Cottage cheese can be quite a bit milder in flavor than mayonnaise and it’s lower in calories and fat.

To make a healthier tuna salad, blend together half a cup of cottage cheese with the ingredients for the traditional recipe.

If you’re looking for an even more mild flavor, try blending equal parts of cottage cheese and Greek yogurt, which will save on calories as well.

4 – Silken Tofu

Silken tofu is a vegan-friendly mayonnaise substitute packed with calcium, good fats, and protein.

The finished dish still has some of the familiar creamy texture of tuna salad but without the dairy.

Mash together 8 ounces of silken tofu with 2 tablespoons of fresh lemon juice, 1 ½ teaspoon of apple cider vinegar, 1 tablespoon of olive or vegetable oil and ¼ teaspoon of sea salt.

Add your desired mix-ins such as celery, pickles or curry powder, then chill in the refrigerator for 30 minutes before serving.

5 – Mustard


For those who don’t like the flavor or texture of mayo, mustard is an excellent alternative.

Mustard can be used to bind tuna and vegetables together just as efficiently as mayo.

Depending on the variety of mustard used, it can add a delightful piquant kick to any tuna dish.

There are many types of mustards to choose from, such as honey mustard, Dijon, or horseradish for example.

Consider adding other flavorful ingredients to help balance out the tartness of certain mustards.

Alternatively, you could mix some mayonnaise into the dish if you prefer a less intense flavor.
