Tuna salad has long been a lunchtime staple, beloved for its simplicity, versatility, and satisfying protein punch. Traditionally made with canned tuna, mayonnaise, and a few mix-ins like celery or onions, this classic dish can be whipped up in minutes. However, while mayo adds creaminess, it can also be heavy, bland, or overpowering. If you’re looking to ditch the mayo and give your tuna salad a flavor boost, we have some delicious and creative swaps that will not only lighten up your meal but also enhance its taste.
The Basics of Tuna Salad
At its core, tuna salad consists of a few essential ingredients that make it a go-to dish:
- Canned Tuna: The star of the dish, packed with protein and omega-3 fatty acids.
- Binder: Traditionally, mayonnaise holds the mixture together and adds creaminess.
- Crunchy Elements: Ingredients like celery, red onion, bell pepper, or pickles provide texture and contrast.
- Acid & Seasoning: A squeeze of lemon juice, vinegar, salt, and pepper brighten up the flavors.
- Optional Additions: Hard-boiled eggs, mustard, fresh herbs, or spices can elevate the dish.
While mayo is the most common binder, it doesn’t have to be the only option. If you’re ready to swap it out, consider these flavorful and nutritious alternatives.
Best Mayo Swaps for Tuna Salad
1. Greek Yogurt – The Creamy, Tangy Alternative

Greek yogurt is one of the best replacements for mayo, offering a similar creamy texture but with a tangy bite and added health benefits. It’s high in protein, probiotics, and calcium, making your tuna salad even more nutritious.
How to prepare it:
- Mix one part Greek yogurt with one part tuna.
- Add a squeeze of lemon juice and a dash of Dijon mustard for an extra punch of flavor.
- Season with salt, pepper, and fresh dill for a bright, fresh taste.
Greek yogurt also provides a lighter alternative that won’t leave you feeling weighed down, making it an excellent choice for those looking to maintain a balanced diet.
2. Avocado – The Rich and Healthy Fat Option
If you love creamy tuna salad but want to ditch the dairy, mashed avocado is an excellent alternative. Avocado provides a buttery texture, a dose of heart-healthy fats, and a mild, nutty flavor that complements tuna beautifully.
How to prepare it:
- Mash half an avocado with a fork until smooth.
- Mix it into your tuna, adding lime juice and a pinch of garlic powder.
- Toss in some chopped tomatoes and cilantro for a fresh, Southwestern-inspired variation.
Avocado also pairs well with spicy seasonings like chili flakes or cayenne pepper, allowing you to customize your tuna salad to your preferred heat level.
3. Hummus – A Mediterranean Twist
Hummus adds a unique, nutty depth to tuna salad while also providing plant-based protein and fiber. It pairs exceptionally well with Mediterranean flavors like olives, cucumbers, and feta cheese.
How to prepare it:
- Stir two tablespoons of hummus into your tuna.
- Mix in diced red onion, cherry tomatoes, and kalamata olives.
- Serve over mixed greens or in a pita pocket for a refreshing, protein-packed meal.
Hummus-based tuna salad works great as a dip for whole-grain crackers or sliced vegetables, making it a great option for a healthy snack as well.
4. Pesto – The Bold, Herbaceous Upgrade

For a more vibrant and gourmet take on tuna salad, swap out mayo for basil pesto. The combination of fresh herbs, garlic, Parmesan, and olive oil adds a bold, aromatic flavor that takes tuna salad to the next level.
How to prepare it:
- Stir in a tablespoon of pesto with your tuna.
- Add sun-dried tomatoes, arugula, and a sprinkle of Parmesan cheese.
- Serve on whole-grain toast for a sophisticated open-faced sandwich.
Pesto lovers can experiment with different varieties such as sun-dried tomato pesto or spinach pesto to introduce unique flavors to their tuna salad.
5. Dijon Mustard – A Zesty and Low-Calorie Option
If you prefer a tangy, slightly spicy kick, Dijon mustard is an excellent mayo substitute. It’s low in calories but packed with intense flavor, making your tuna salad more dynamic.
How to prepare it:
- Mix one teaspoon of Dijon mustard into your tuna.
- Add capers, chopped scallions, and a touch of olive oil for balance.
- Serve on a bed of greens for a light and flavorful meal.
Dijon mustard works well with additional seasonings like smoked paprika or curry powder for those looking to elevate their tuna salad even further.
