This flavorful Keto Tuna Salad is the perfect option for a low-carb lunchtime meal. It’s easy to make, nutrient-dense, and fully gluten-free!

If you know me, you know I am NOT A FAN of boring salads. If I am going to be eating healthy salads, I want them to also be fun and interesting! And I am not interested in eating the same salad every single time.

Enter the tastiest keto tuna salad recipe ever! It’s loaded with simple but nourishing ingredients packed full of flavor, and it’s perfect for quick and easy lunches.

The tuna salad has a tangy and savory flavor, with a hint of acidity from the lemon. The creamy texture of the mayonnaise blends perfectly with the delicate flakes of tuna, creating a rich base that is uplifted with tasty additions like celery, red onion, and capers.

Is Keto Tuna Salad healthy?

Absolutely. This tuna salad is good for you! Tuna is a source of selenium and vitamin D. It’s also a good source of protein and healthy fats, making it a great keto food to enjoy!

The keto diet is a long-term or short-term dietary approach where you consume a very low amount of carbohydrates, a moderate amount of protein, and a high amount of healthy fats.

This shifts your body into a metabolic state called ketosis, in which it primarily burns fat for energy instead of carbohydrates. This process can aid in weight loss, and there is some evidence that it may help alleviate inflammation.

What’s the best tuna to buy?

Always opt for high-quality canned or jarred tuna with no added ingredients aside from the liquid it is stored in.

I prefer to use tuna stored in water because it’s lower in calories compared to tuna stored in oil. If you don’t mind the added calories and prefer the boost in flavor that tuna stored in oil has, opt for olive oil over any other oil.

Olive oil is generally considered healthier than other oils like sunflower oil or vegetable oil due to its higher content of monounsaturated fats. It’s also not mixed, like vegetable oil often is, so you know you’re getting a higher-quality oil with your tuna.

How to make ahead and store?

Stored in an airtight container in the fridge, the salad will last up to 4 days and can be used as lunch or a light protein-packed snack throughout the week. Freezing is not recommended as it will affect the texture of the dish once thawed.

Serving Suggestions

While this tuna salad does make excellent tuna salad lettuce wraps, there are other ways you can serve it.

Almond-Flour Crackers and Flax Seed Crackers are both great low-carb crackers for dipping, and this Keto Almond-Flour Bread or this Cauliflower Bread can be sliced and toasted to make tuna salad sandwiches. For something a bit more fun, you can also toast some Keto Tortillas in a pan and make little tuna salad roll-ups!
