This Mediterranean Keto Tuna Salad is something different! It’s delicious and it’s got some surprising ingredients in it, making this the perfect keto tuna salad for sandwiches (on low-carb bread), putting on top of keto crackers, serving with avocado – like I do in this recipe – or just out of the bowl on its own. Follow me, Chef Jenn, along as I show you all my tips and tricks to make the best keto tuna salad recipe ever!
This isn’t your typical gloppy mayonnaise-y tuna salad – in this Mediterranean Tuna Salad, a humble can of tuna gets an upgrade!
What You Need to Make Mediterranean Tuna Salad
- A mixing bowl – these mixing bowls are amazing, indestructible, and will last a lifetime
- Solid knife for chopping – this Henkles knife is a great value for the quality
- Cutting board
Ingredients to Make This Tuna Salad
- Sour cream
- Feta cheese – use ricotta salata if you prefer
- Red bell pepper
- Shallot – shallots are like a mild onion but are actually in the garlic family. Use green onion if you have no shallots.
- Salt and pepper
What Kind of Tuna Should You Use?
Tuna packed in water, tuna packed in oil. Tuna with herbs and seasonings. White albacore tuna. And a million different brands. It can be confusing, but here’s the bottom line: whatever tuna you like or have on hand will probably work in this recipe!
Tuna in water – just drain off the water and give it to the cat.
Tuna packed in oil – drain and discard the oil.
The only tuna I’d be reluctant to use is tuna with seasonings because you don’t want the flavor to conflict with the recipe.
How to Make Gluten Free Tuna Salad
- Drain the tuna and put it in a bowl. Add the mayo, sour cream, crumbled feta, chopped red bell pepper, shallot, parsley, and salt and pepper.
- Mix well.
- Cut the avocados and pop out the seed. Serve each half an avocado with 1/4 cup of Mediterranean Tuna Salad.
Chef’s Tips to Make This Low-Carb Tuna Salad
- Don’t like capers? Substitute some chopped olives.
- Don’t have shallots? Use green onion.
- Don’t have fresh parsley? Use 1 tsp dried parsley.
- Don’t have sour cream or mayo? Use the full amount of whichever you have.
- Don’t have a can of tuna? Use a can of well-drained chicken!
How to Serve With Mediterranean Keto Tuna Salad
I like to enjoy this salad inside the cavity of a nice, fresh avocado. That makes a filling meal, or you can use this tuna salad in a lettuce cup, in a low-carb wrap, on top of your favorite Keto Crackers, or enjoy it as a part of composed salad plate along with this Southern Chicken Salad and Shrimp Salad.
Will This Tuna Salad Recipe Freeze?
Sadly, no. The sour cream and mayo don’t freeze well and this recipe will lose texture and liquid through the freezing and defrosting process.
This dish is best eaten fresh.
How Long Will This Mediterranean Keto Tuna Salad Keep?
It is tuna, which has a shorter shelf life than some other proteins, so try to eat it within 2-3 days.
