Easy Keto Tuna Salad – Only 5 Ingredients

You’ve been hearing about keto diets for a while now, and many of you have decided to give it a try. Maybe you have been following the keto diet for a while and are familiar with the food choices you can make, and those you won’t. But what about the meat, fish, and dairy that you are going to be eating? What about the fat content? Well, don’t worry!!! It’s not as hard as you think! I’m going to show you how to get on the keto diet, what to expect, and how to fill your plate with delicious foods that you will love!

When people hear the word “keto”, most think of the ketogenic diet, which is a high-fat, moderate-protein, low-carb diet. However, there are also ways to eat healthy with a keto-like diet that do not involve cutting carbs. It is possible to eat a keto-lifestyle without having to cut your carbs, and this recipe is a nice way to do so.

There is a keto diet and there is a keto diet. The food that you eat depends on what you are seeking to target and get in your body. Different foods will have different effects and are generally not interchangeable. For example, certain foods that are typically high carb for someone following a low carb diet may be more suitable for someone following a Keto diet.

Tuna salad is a quick and simple dinner, and with just 5 ingredients, it just became a whole lot easier!

If you want to create a low-carb keto tuna salad, you must try this easy recipe. Canned tuna, mayo, green onion, pickle, and lemon juice are all you need to create this keto tuna salad. If you’re feeling particularly fancy, add paprika, garlic, salt, and pepper to the mix.

Even the most sluggish keto diet can benefit from this low-carb tuna salad. Anyone can prepare it in 5 minutes and have a high-quality meal on the table.

Is Mayo a Keto Food?

Because they have low carb macros, all mayos are technically acceptable on a keto diet. Most ordinary mayos, on the other hand, will utilize low-quality, high-inflammatory oils.

Vegetable oil, peanut oil, canola oil, and soybean oil are examples of these oils. Instead, look for mayonnaise prepared from olive or avocado oil. Olive oil mayonnaise is a bit more costly, but it’s definitely worth it to prevent any further irritation.

For keto tuna salad, some of our favorite brands to purchase mayo from are:

  • Avocado oil is a high-quality product that is almost flavorless, making it a wonderful addition to any dish. Primal Kitchen Avocado Oil Mayo– Avocado oil is a high-quality product that is nearly flavorless, making it a fantastic addition to any recipe.
  • Primal Kitchen Duo Mayos– With a normal mayo and a low-carb pesto mayo, this pack offers you double the flavor. This simple keto tuna salad dish might benefit from the addition of pesto mayo.
  • Sir Kensington’s Avocado Oil Mayo– Another high-quality low-carb mayo that is somewhat less expensive than other choices. It’s sugar-free and carb-free, making it ideal for a healthy keto diet.
  • Chosen Foods Mayo is the last high-quality mayo option. It contains high-quality components derived from high-quality avocados. This is the ideal combination for making a low-carb, high-fat dish.

These are all excellent mayonnaise alternatives that can be used in a number of keto recipes. Everything from keto tuna salad recipes to casseroles and keto sandwiches will benefit from them.

Mayonnaise made with olive oil or avocado oil

We mentioned before that avocado oil or olive oil may be used in low carb mayo. The only reason most of the alternatives above used avocado oil is because finding a clean olive oil mayo is tough. To save money, most firms cut their mayo with low-cost oils, which is why avocado oil brands are so costly.

So, any will do; it’s simply a question of choosing a brand that isn’t substituting a lower-cost alternative for their high-quality oil.

What Should You Put in Your Tuna Salad on the Keto Diet?

Need a nice keto dinner but are frustrated by the lack of adaptable choices for tasty recipes? Our keto tuna salad is low in net carbohydrates, tasty, and completely adaptable to your preferences.

To make dinner prep a breeze, we’ve collected a list of all our favorite spices, ingredients, and tuna salad meal ideas.


Everyone knows there’s salt/pepper to taste in every excellent meal, but did you realize you can spice up the same foundation and create hundreds of distinct flavor profiles?

Once we’ve got the tuna salad foundation down, we enjoy experimenting with seasonings to come up with different flavors. The following are some of our favorite spices to use:

  • Curry Powder– Use sugar-free cranberries and curry powder to make a wonderful curried tuna salad.
  • Salt and pepper—Of course, this is a must-have, but don’t be afraid to season to taste.
  • Paprika– Do you like a little heat? To dress up your tuna salad, paprika is the ideal tiny spicy, smoky spice.
  • Thyme– Thyme will create a light and poppy tuna salad that is more herby.
  • Basil– Similar to thyme, basil has an almost Italian taste that works nicely with low-carb yet delicious keto tuna salad.

+ More Vegetables

When it comes to keto tuna salad toppings, the possibilities are almost limitless. To create a well-rounded gourmet keto tuna salad, toss in your favorite toppings or stick to a theme. Here are a few of our favorites:

  • Celery, diced– This is by far my favorite ingredient to use in any keto tuna salad dish. It’s both refreshing and crunchy, providing a great texture contrast.
  • Bell Pepper– Finely slicing bell pepper offers you a crunch comparable to celery but without the fiber, which may be easier on the stomach for some individuals. Green peppers are the most keto-friendly, but any bell pepper will suffice if you use a modest portion size.
  • Red onion– Red onion, or any onion for that matter, adds a lot of flavor and texture to keto tuna salad.
  • Boiled Eggs– Adding boiled eggs to keto tuna salad boosts the protein content and creates an egg salad-tuna salad hybrid.

Because of the quick prep time for this dish, you may have a wonderful tuna salad ready in minutes to enjoy all week. Begin personalizing your meal to make it your own.

Make a Meal Out of It

By adding a few additional ingredients, this keto tuna salad dish transforms into a high-quality dinner. The following are some of our favorite dinner themes:

  • Greek Tuna Salad– Omit the pickle and add red onion, feta, kalamata olives, and cherry tomatoes to the basic recipe.
  • Mexican Tuna Salad– Omit the pickle and add chile lime or tajin spice, avocado pieces, cojita cheese, and a pinch of cilantro to this foundation.
  • Tuna Melt Salad– Make this keto tuna salad, but use tuna that has been cooked in olive oil or water. After that, finely dice the pickle and a little amount of white onion. When done, press the tuna salad flat into a bowl and top with a generous amount of cheddar cheese. Microwave until the cheese is melted and gooey, about 2 minutes.

You can always prepare the basic keto low carb tuna salad and then meal prep it later to personalize it with toppings.

Tuna Salad on the Keto Diet: How to Make It

Now that we’ve discussed how to choose the finest low-carb tuna salad/keto choice, it’s time to get to work on the preparation.

You’ll Need These Ingredients

Unlike other salad recipes, we can maintain this one gram of net carbohydrates since we utilize mostly protein and fat. The pickle and onion are the sole sources of carbohydrates.

Tuna, mayo, green onion, pickle, lemon juice, and salt and pepper to taste are required for this dish. We use tuna fish that has been canned in water, but you could instead use tuna fish that has been packed in olive oil.

To prepare this wonderful dish, start by finely cutting the green onion and pickle. Then pour into a basin.

It’s best served with Keto-Friendly Dippers.

Low-carb tuna salad may be prepared in a number of ways, depending on how fast and simple you want to serve it. Here are some great lunch options to offer with this delectable tuna salad:

  • Lettuce cups are the traditional keto diet serving vessel.
  • Pork Rinds– My personal favorite since it adds a little crunch to a creamy dish. It’s also simple to prepare since you don’t have to “create” anything!
  • Keto Crackers– We wrote a whole blog article on keto crackers, including our favorite and unique recipes. They’re simple to prepare and provide a salty flavor to the dish.
  • Cucumber and celery are by far the most hydrating. Because they are high in water, they are light and hydrating.
  • Bell Pepper– A low carb tuna boat may be made by slicing bell pepper into 1′′ cracker sized pieces.

If you prepare this dish, you may serve it in any of these low-carb ways. They’re perfect for a keto diet and need very little preparation.

On a Keto Diet, Can I Eat Canned Tuna?

Tuna in a can is ideal for a keto diet. While you don’t need to be concerned about anything unique to the keto diet, there are some bigger issues with eating canned tuna in excess. Tuna in a can includes mercury, which may be harmful in large doses. Another source of worry is the can itself, which contains a lot of BPA.

What Kind of Tuna Should I Use in a Keto Tuna Salad?

It’s entirely up to you whatever kind of tuna you use for this dish. Albacore and skipjack tuna are the two most common kinds seen in supermarkets. Although many people favor albacore tuna, I love both types in my keto tuna salad dish.

Is Keto Tuna Salad Freezable?

No, freezing keto tuna salad is not a good idea. When mayonnaise is frozen, it loses its texture and taste. This dish should be prepared ahead of time or kept refrigerated for up to two days.

More Simple Recipes

We love quick and simple meals, and we know you do, too. As a result, the keto meals on are straightforward and healthy. No one should have to spend an arm and a leg on nutritious food or struggle to figure out what to use.
