Tuna Avocado Salad with Mustard Dressing Ingredients

This recipe uses simple, wholesome ingredients that are easy to find and combine into a nutrient-rich meal. Each component adds flavor, texture, and nutritional value to the final dish.

For the salad base:
Use 2 cans of tuna in water or olive oil, drained well. Tuna provides a rich source of protein and a savory, flaky texture that forms the foundation of the salad.

Add 2 ripe avocados, peeled, pitted, and diced. Avocado brings creaminess, healthy fats, and a smooth texture that balances the saltiness of the tuna.

Include 1/2 small red onion, finely chopped. This adds a mild sharpness and crunch that enhances the overall flavor.

Add 1 small cucumber, diced, for freshness and hydration.

Optional but recommended: 1/2 cup cherry tomatoes, halved, for a burst of sweetness and color.

For the mustard dressing:
Use 2 tablespoons Dijon mustard for a tangy, slightly spicy base.

Add 2 tablespoons olive oil for richness and smoothness.

Include 1 tablespoon lemon juice or apple cider vinegar for brightness.

Add 1 teaspoon honey or maple syrup for a subtle touch of sweetness that balances the mustard.

Season with salt and black pepper to taste.

Optional additions:
A handful of chopped parsley or dill for freshness and herbal aroma.

Tuna Avocado Salad with Mustard Dressing Directions

Start by preparing all your ingredients. Drain the tuna thoroughly to remove excess liquid, then flake it gently into a large mixing bowl using a fork. This helps create a light texture that blends well with the other ingredients.

Next, prepare the avocado. Cut it into small, even cubes and gently add it to the bowl. Be careful when mixing later, as avocado is soft and can mash easily.

Add the chopped red onion, diced cucumber, and cherry tomatoes if using. These vegetables bring crunch, freshness, and color to the salad, making it more vibrant and enjoyable.

In a separate small bowl, prepare the mustard dressing. Whisk together Dijon mustard, olive oil, lemon juice or vinegar, and honey until smooth and slightly creamy. Taste and adjust seasoning with salt and pepper. The dressing should be tangy, slightly sweet, and well balanced.

Pour the dressing over the salad ingredients. Using a soft spoon or spatula, gently fold everything together. Try not to overmix, as you want to keep the avocado pieces intact while evenly coating all ingredients with the dressing.

Once combined, let the salad sit for about 5 to 10 minutes. This allows the flavors to blend and the dressing to lightly absorb into the tuna and vegetables.

Serve immediately for the freshest taste. You can enjoy it in a bowl, over a bed of greens, or as a filling in wraps or sandwiches.

Tuna Avocado Salad with Mustard Dressing Notes

This salad is best enjoyed fresh because avocado tends to soften and slightly brown over time. However, if you want to prepare it ahead, you can store the tuna mixture separately and add the avocado and dressing just before serving.

For extra protein and texture, you can add boiled eggs, chickpeas, or quinoa. These additions make the salad even more filling and suitable as a complete meal.

If you prefer a stronger flavor, you can increase the Dijon mustard slightly or add a pinch of garlic powder to the dressing. For a milder version, reduce the mustard and increase the olive oil or honey slightly.

To keep the avocado fresh if storing briefly, you can toss it lightly in lemon juice before mixing it into the salad. This helps slow down oxidation and maintains its color.

This recipe is naturally gluten-free and can be adapted for low-carb or keto-friendly diets by adjusting the sweetener or omitting it entirely.

It also works well as meal prep when stored properly, but it’s best consumed within 24 hours for optimal texture and flavor.
